Graphene, perovskites, and silicon – an ideal tandem for efficient solar cells

Posted By Graphene Council, Wednesday, March 4, 2020

Graphene Flagship researchers at the University of Rome Tor Vergata, the Italian Institute of Technology (IIT) and its spin-off, Graphene Flagship Associate Member BeDimensional, in cooperation with ENEA have successfully combined graphene with tandem perovskite-silicon solar cells to achieve efficiencies of up to 26.3%. Moreover, they envisioned a new manufacturing method that, thanks to the versatility of graphene, allows to reduce production costs and could lead to the production of large-area solar panels. Graphene-based tandem solar cells almost double the efficiency of pure silicon.

Laws of physics limit the maximum efficiency of silicon solar cells to 32%. For that reason, scientists have spent decades trying to come up with other alternatives, such as III-V and perovskites. However, the latter present several manufacturing challenges, and scaling up the production of solar panels is a key step towards success. With 'tandem cells', scientists  had previously combined the advantages of both silicon and perovskites – however stability, efficiency and large-scale manufacturing still seemed like a far-fledged dream.

But then graphene came into play – and it could be a game changer. Graphene Flagship researchers identified its potential for energy harvesting, and in fact have dedicated two different industry-oriented 'Spearhead Projects' to dig into the possibilities of graphene-based solar cells. This new paper published in Joule – a reference journal in the field of energy research – is yet another proof that graphene and related layered materials will enable the commercialisation of more efficient and cost-effective large area solar panels.

Aldo di Carlo, lead author and researcher in Graphene Flagship partner University of Rome Tor Vergata, explains: "Our new approach to manufacture graphene-enabled tandem solar cells provides a double advantage. First, it can be applied to enhance all the different types of perovskite solar cells currently available, including those processed at high temperatures. But more importantly, we can incorporate our graphene using the widespread 'solution manufacturing methods', key to further deploy our technologies industrially and deliver large-surface, graphene-enabled solar panels."

Francesco Bonaccorso, co-author, co-founder of Graphene Flagship spin-off BeDimensional, says: "This innovative approach proposed in the context of the Graphene Flagship is the first step toward the development of tandem solar cells delivering an efficiency higher than the limit of single junction silicon devices. Layered materials will be pivotal in reaching this target.".

Emmanuel Kymakis, Graphene Flagship Energy Generation Work Package Leader, says: "There are some compatibility issues that have to be tackled before the full exploitation of the perovskite-Si tandem PVs concept. This pioneering work demonstrates that the integration of GRMs inks with on-demand morphology and tuneable optoelectronic properties in a tandem structure, can lead to high-throughput industrial manufacturing. Graphene and related materials improve the performance, stability and scalability of these devices.

The stacked silicon-perovskite configuration will act as the foundation of the new Graphene Flagship Spearhead Project GRAPES, in which a pilot line fabrication of graphene-based perovskite-silicon tandem solar cells will take place, paving the way towards breaking the 30% efficiency barrier and a significant decrease on the Levelized Cost of Energy."

Andrea C. Ferrari, Science and Technology Officer of the Graphene Flagship and Chair of its Management Panel, adds: "The application of graphene and related materials to solar energy generation was recognized as a strategic priority since the start of the Graphene Flagship. The first graphene-based solar farm is being set up this year. These new results underpin our effort for the following 3 years to produce panels defining the state of the art. This also shows how the work of the Graphene Flagship strongly aligns with the UN's Sustainable Development Goals."

Synergistic Antiviral Activity of Graphene Oxide and Common Antiviral Agents

Posted By Graphene Council, Wednesday, March 4, 2020
Not only does loading antiviral agents on graphene oxide produce a synergistic antiviral effect, but it also enhances the biocompatibility and reduces the cytotoxicity of the drugs. Researchers have found that the antivirus nanomedicines designed based on GO which have been tested against a specific virus can also exert the same antiviral effect against a wider range of viruses from the Herpesviruses to the novel Coronavirus.

Due to their two-dimensional structure, sharp edges, and negatively charged surfaces, graphene oxide (GO) nanosheets are capable of interacting with microorganisms such as bacteria and viruses and destroying them by disrupting their plasma membrane or by generating reactive oxygen species to induce oxidative stress. Nevertheless, GO also interacts with living cells depending on its concentration; as the wise saying goes: “The only real difference between medicine and poison is the dose....and intent.”

On the other hand, there are a large number of substances whose antimicrobial properties have been proven over the years, among which are hypericin and curcumin; studies have shown that hypericin and its derivatives, which are extracted from Hypericum perforatum, have antiviral activity against a broad spectrum of viruses including the herpes simplex virus types 1 & 2, influenza virus, Sendai virus, chronic hepatitis C virus, etc.

Hence, now it is time to integrate what researchers have learned during all those years of research and experiment; GO’s high drug-loading capacity and low cytotoxicity make it the standout choice as a drug carrier; according to a recent study conducted by the researcher of Sichuan Agricultural University, loading an optimized dosage of hypericin on GO reduced its cytotoxicity while improving its antiviral activity both in vitro and in vivo. The resulting antiviral combination was tested against novel duck reovirus (NDRV) and reported to inhibit its replication by preventing the transcription of its target gene and suppressing the expression of its target protein in the early stage of the treatment. Moreover, in vivo tests indicated that hypericin-loaded GO could reduce pathological lesions of the ducklings infected with NDRV, thus increasing their chance of survival.

Similar antiviral and antibacterial effects have also been seen in curcumin, which is the most biologically active substance in Curcuma longa – also known as turmeric. In 2017, a group made up of American and Chinese researchers reported in their article – published in the Nanoscale journal – that loading curcumin on GO not only did improve the biocompatibility of GO but also reduced the cytotoxicity of both GO and curcumin. Their studies revealed that curcumin-loaded GO had synergistic antiviral activity against the respiratory syncytial virus, and inhibited its binding to host cells. This virus is recognized as the major viral pathogen of the lower respiratory tract in infants.

Apart from the curcumin itself, carbon quantum dots derived from curcumin have been proven effective against enterovirus 71 (EV71). In a new study carried out in Taiwan, core-shell quantum dots were synthesized from curcumin using a one‐step dry heating method, resulting in their surfaces preserving many of the moieties of polymeric curcumin, as if curcumin were loaded on the quantum dots. Figure 1 schematically illustrates the synthesis process and antiviral activity of these nanomaterials; accordingly, the mechanism behind their antiviral activity is inhibiting the EV71 virus from both attaching to the host cells, replicating, and exiting from the infected cells.

What is remarkable about all three of these studies is that loading antiviral agents on GO enhances its biocompatibility while reducing the cytotoxicity of both GO and the antiviral agents (e.g., curcumin and hypericin), in addition to the fact that the two substances combine synergistically to form a more effective therapeutic agent than each of those substances alone. Furthermore, researchers have found that the antivirus nanomedicines designed based on GO which have been tested against a specific virus can also exert the same antiviral effect against a wider range of viruses from the herpes virus to the novel Coronavirus.

Concrete results: First Graphene and University of Adelaide use graphene to produce high-strength cement

Posted By Graphene Council, Wednesday, March 4, 2020
Graphene additives from First Graphene have been shown to increase the strength of cement mortar significantly, enabling the construction of lighter and more environmentally friendly buildings and civil engineering structures.

In a paper published in the journal Construction and Building Materials, researchers at the University of Adelaide report that the addition of just small amounts of First Graphene’s PureGRAPH® products to cement can increase the building material’s compressive and tensile strengths by 34% and 27%, respectively.

These findings are significant given the impact that the production of cement has on the environment. Cement is the source of about 8% of the world's carbon dioxide (CO2) emissions, according to the UK's Royal Institute of International Affairs. If the cement industry were a country, it would be the third largest emitter in the world, behind China and the US. It contributes more CO2 than aviation fuel (2.5%) and is not far behind the global agriculture business (12%)[1].

Chief technology officer, at First Graphene, Dr. Andy Goodwin, says: “By increasing the strength of concrete with PureGRAPH®, we can use less material to produce a structure with the necessary mechanical properties. If it was to be adopted across the construction industry, we believe that the use of PureGRAPH® could cut global CO2 emissions by approximately 2.5%.”

The University of Adelaide researchers have tested a number of graphene-enhanced mortars, and they have found that a mixture containing 0.07%-by-weight ultra-large size (56 ± 12 µm) pristine PureGRAPH® possesses optimal mechanical properties. This enhancement is attributed to improvements in the degree to which the cement paste hydrates, which results in the production of more calcium silicate hydrate gel. Adhesive bonds are also created as a result of friction generated between the sheets of PureGRAPH® and the cement gels, strengthening the cement matrix composites and impeding the development of cracks within them.

These benefits are achieved with little-to-no modification to the mortar production process. Dr. Andy Goodwin says: “The PureGRAPH® concrete additive was introduced as an admixture directly in the water used for preparing the cement mortar. No additional mixing equipment or processing steps were required.”

First Graphene has developed an electrochemical process that enables the tonnage-scale manufacture of pristine, high-aspect-ratio platelets of graphene with a typical thickness of 5-10 carbon layers. Dr. Andy Goodwin concludes: “The initial results obtained by the University of Adelaide researchers using our graphene are extremely encouraging. We look forward to the next stage in our partnership, as we continue to develop leaner, greener concrete materials.”

Graphene from sugar, a sweet protocol

Posted By Graphene Council, Saturday, February 29, 2020

Scientists from the Centre for Nano and Soft Matter Sciences, Bengaluru, an autonomous institution under the Department of Science & Technology, Government of India have synthesised reduce graphene oxide (rGO) by the combustion of table-sugar.

The group led by Prof. C. N. R. Rao consisting of Dr. P. Chithaiah from CeNS and Prof. G. U. Kulkarni from JNCASR, Bengaluru has developed a rapid and simple route for the synthesis of rGO by the combustion of table-sugar. This method being single-step and reproducible is advantageous compared to the reported protocols used presently. Further, the synthesis doesn’t involve any metal catalysts, expensive reagents, solvents, hazardous chemicals, and, most importantly, it has the ability to produce graphene oxide in large quantities at rapid rates.

Graphene, a one-atom-thick, two-dimensional sheet of sp2 hybridized carbon atoms is known as a wonder material, as it is stronger than diamond, conducts better than copper along with many other interesting properties. However, the production of graphene in large scale has many challenges to address. 

Till date, methods like chemical vapor deposition, arc discharge, aerosol pyrolysis, mechanical exfoliation, solvothermal, hydrothermal synthesis, laser reduction of graphite oxide have been developed to prepare graphene (reduce graphene oxide, rGO).

All these methods either involve hazardous chemicals, high temperatures, and inert atmosphere making them expensive and thus becoming irrelevant for bulk scale applications.

The team believes that the process developed may have a significant impact on various products, including batteries. Their work has been published in the ‘Beilstein Journal of Nanotechnology.’

Oil separation made easier with 2D material membrane

Posted By Graphene Council, Friday, February 28, 2020
University of Manchester researchers have made a leap forward in overcoming one of the biggest problems in membrane technology- membrane fouling.

Membrane-based separations are essential for various processes, such as water filtration and oil and gas separation. The use of graphene and other 2D materials in membrane technology has attracted significant attention due to the tunability of these materials making it possible to filter impurities previously not thought possible.

Fouling is an inevitable event in membrane separation, where blockages occur in the pores of a membrane, stopping the flow and preventing the membrane from functioning normally. Fouling is an especially severe issue for oil separation technology due to how easily the oil droplets stick onto the membrane surface.

Published in Nature Communications, the team based in the Department of Chemical Engineering & Analytical Science, Henry Royce Institute and the National Graphene Institute in collaboration with University College London (UCL), have demonstrated that the exfoliated two-dimensional form of vermiculite, a natural clay mineral, can be used as a fouling resistant coating for oil-water separation.

It is well known that increasing the water wettability and decreasing the oil adhesion on a membrane can reduce membrane fouling due to oil deposition. The scientific community has in the past mainly focused on tuning the surface charge of the membrane by chemical modification to enhance the water wettability and hence reduce fouling. These attempts have succeeded in part, but long-term antifouling properties were yet to be attained.

Now the team at The University of Manchester have found that the wetting properties of vermiculite membranes, prepared by stacking many layers of two-dimensional vermiculite sheets, can be tuned from super-hydrophilic to hydrophobic simply by exchanging the cations present on the surface and between the layers of vermiculite.

Developing antifouling membranes for oil-water separation is a long-sought objective for scientists and technologists, which is evident from the rapid growth in the number of publications in this area, Professor Rahul Raveendran Nair.

Further, the team also demonstrated how to exploit this unusual property for reducing the membrane fouling during oil-water filtration by using superhydrophilic lithium exchanged vermiculite (lithium vermiculite) as a coating layer for commercial microfiltration membranes.

Dr Kun Huang, the lead author of the paper said: “Lithium vermiculite membranes not only provide superhydrophilicity but also repel oil droplets during filtration due to their underwater superoleophobic property. The under-water oil adhesion on vermiculite coated microfiltration membranes was more than 40 times lower than the noncoated membrane.”

The demonstrated oil-water separation is just one example of the use of super-hydrophilic antifouling membranes. Their application could be expanded to other areas such as developing self-cleaning surfaces, and antifouling filters for biofiltration.

Professor Rahul Raveendran Nair said: “Developing antifouling membranes for oil-water separation is a long-sought objective for scientists and technologists, which is evident from the rapid growth in the number of publications in this area. We believe our work provides a major advance in the fundamental understanding of wetting properties of solids down to the molecular level and is a notable milestone in the development of robust fouling resistant membrane technologies.”

The work was done in collaboration with scientists from the Department of Physics & Astronomy at UCL to probe the mechanism of the unusual water wetting transition in the vermiculite membrane upon ion exchange.

Patrick Rowe, from UCL said: “Our study shows how the atomic-scale details of the interaction between water molecules, surfaces and ions are important for understanding the surface properties of solids. The high water affinity and hence lower oil droplet interaction of the lithium vermiculite is due to the unique arrangement of water molecules on the surface of lithium vermiculite.”

Dr. Christie Cherian, who co-authored the paper said, “The presence of ions in the vermiculite membrane helped to pin the water molecules firmly on the surface even when the membrane is exposed to oil for a prolonged period of time, a property unique to the vermiculite coated membrane, shows promise for using it as a long-term antifouling coating.

Study puts spin into quantum technologies

Posted By Graphene Council, Thursday, February 27, 2020

A team of international scientists investigating how to control the spin of atom-like impurities in 2D materials have observed the dependence of the atom's energy on an external magnetic field for the first time.

The results of the study, published in Nature Materials, will be of interest to both academic and industry research groups working on the development of future quantum applications, the researchers say.


Researchers led by Prof Vladimir Dyakonov at the University of Würzburg in collaboration with scientists from the University of Technology Sydney (UTS), the Kazan Federal University and the Universidade Federal de Minas Gerais, demonstrated the ability to control the spin of atom-like impurities in 2D material hexagonal boron-nitride. By combining laser and microwave excitation the researchers were able to change the spin states, for example "up" to "down", of atom-like impurities hosted in the material and show the dependence of their energy on an external magnetic field.

This is the first time that the phenomenon has been observed in a material that is made of a single sheet of atoms like graphene. The researchers say that this newly demonstrated quantum spin-optical properties, combined with the ease of integrating with other 2D materials and devices, establishes hexagonal boron-nitride as an intriguing candidate for advanced quantum technology hardware.

"2D atomic crystals are currently some of the most studied materials in condensed matter physics and materials science," says UTS physicist Dr Mehran Kianinia, a co-author of the study.

"Their physics is intriguing from a fundamental point of view, but beyond that, we can think of stacking different 2D crystals to create completely new materials, heterostructures and devices with specific designer properties," he says.

UTS researcher, Dr Carlo Bradac, a senior co-author of the study says that in addition to adding another unique property, to an already impressive range of properties for a 2D material, the discovery has enormous potential for the field of quantum sensing.

"What really excites me is the potential [in the context of quantum sensing]. These spins are sensitive to their immediate surroundings. Unlike 3D solids, where the atom-like system can be as far as a few nanometres from the object to sense, here the controllable spin is right at the surface. Our hope is to use these individual spins as tiny sensors and map, with unprecedented spatial resolution, variations in temperature, as well as magnetic and electric fields onto variations in spin" Dr Bradac says.

"Imagine, for instance, being able to measure minuscule magnetic fields with sensors as small as single atoms. The possibilities are far reaching and range from nuclear magnetic resonance spectroscopy for nanoscale medical diagnostic and material chemistry to GPS-free navigation using the Earth's magnetic field," he says.

However quantum-based nanoscale magnetometry is "just one area where controlling single spins in solids is useful" says senior author of the study UTS Professor Igor Aharonovich.

"Beyond quantum sensing, many quantum computing and quantum communication applications rely on our ability to control the spin-state--zero, one and anything in between--of single atom-like systems in solid host materials. This allows us to encode, store and transfer information in the form of quantum bits or qubits," he says.

Amongst many others, this research highlights how scientists are quickly becoming masters in the craft of manipulating objects in the quantum regime. In fact, achievements like Lockheed Martin's Black Ice project and Google's quantum supremacy are proof that we are striding away from mere proof-of-concept experiments towards real world, quantum-enabled solutions to practical problems.

Gratomic Provides Update to Shareholders

Posted By Graphene Council, Tuesday, February 25, 2020
Gratomic Inc is pleased to provide the following update to shareholders on general operations and the issuance of mining license ML215.

Mining License Update


On the 24th of January the Company's Co-CEO, Arnoldus Brand met with the Ministry of Mines and Energy in Namibia to satisfy a request that came from the special committee that is in charge of recommending the mining license request to the Minister of Mines and Energy, to provide an update on mine development and to fulfill certain criteria required for the approval of the mining license.

The Company is happy to report that it fulfilled 100% of the required criteria during the meeting and was requested to amend the current Environmental Impact Assessment and Environmental Management Plan over EPL 3895 to include ML 215.

After meeting with the members of the special committee, the Company immediately engaged Risk-Based Solutions (RBS) CC, Consulting Arm of Foresight Group Namibia (FGN) (Pty) Ltd, to start amending the EIA and EMP to include ML215. The final submission of the amended EIA and EMP was done on the 17th of February 2020. Through this submission Gratomic has now fulfilled all requirements to satisfy the committee's requests and is now waiting to hear back from the Ministry of Mines and Energy with respect to the granting of mining licence ML215.

We would like to thank the Ministry for their co-operation and hard work to help Gratomic advance towards a mining company from a junior exploration company.

Operations Update

The Chinese manufacturing facility that is supplying the last pieces of equipment that make up the greater part of the drying circuit for the Aukam mine graphite processing plant has experienced significant delays due to the impact of the Coronavirus and has been unable to ship the equipment. The Company has been waiting for correspondence from the manufacturer on the platform designs that are required to be poured at the same time as the shipment leaves China to provide a sufficient curing period for the concrete platforms. The minimum shipping time from China to Namibia is 39 days once the equipment leaves port. We foresee further delays at both the port of China and the port of Walvis Bay given strict quarantine restrictions at both ports currently.

On the 19th of February the Company received feed-back from the manufacturer on the platform designs and confirmation that some of the staff have returned back to the factory and it is now able to proceed with shipping of the remaining equipment.

The List of Equipment from China includes the following:

Cyclone Cluster

10 m Electrical Dryer

Thickener

600 mm conveyor belt

Filter press

Slurry pumps and lines

The equipment was specifically designed and built to accommodate mass balance pull and the treatment of Aukam Graphite based on the results of our pilot testing programs.

The remainder of the equipment has already been set up on site and what remains is the arrival of this equipment to fully complete the 20,000 tonnes per year operating capacity of the processing facility.

We appreciate the patience of our shareholders during this delay.

We further sympathize with our Chinese vendors as they have been going through a difficult time.

Management Update

In an effort to reduce the Company's expenditures, the majority of Namibian staff and management has agreed to go to 50% remuneration as per SECTION 12 (6) OF THE NAMIBIAN LABOUR ACT NO 11 OF 2007 until the granting of ML215. The Canadian management team has lead by example by doing the same in an effort to preserve capital for operations.

The efforts by the Namibian team to agree to such conditions is extraordinary and shows their commitment to the success of the business.

We thank each and every one of our devoted and hard-working employees for their commitment towards the success of Gratomic as a company.

Financing Update

Gratomic further pushes to conclude its current financing as the Company moves towards fully commercializing its assets.

To date the Company has raised CAD $626,000 of up to a CAD $2.5 million-dollar issuance.

Management has excelled beyond their calling to do as much as they can to further operations along and will continue to work relentlessly to earn success.

TODA Notes Update


Further to the press release of October 17, 2019, where Gratomic announced the Supply Agreement with TODAQ Holdings ("TODAQ") to supply TODAQ with an aggregate of USD $25,000,000 of graphite, payable in TODA Notes ("TDN"), and the subsequent press release on December 20, 2019 where Gratomic received its first of two purchase orders from TODAQ, Gratomic is pleased to provide an update on the current status of TDN trading. TDN has been trading on BitForex, a digital asset exchange, with a 30-day average price and volume of approximately USD $0.24 and USD $950,000, respectively. TDN first started trading on Bitforex on November 1, 2019 at a price of USD $0.10 and a volume of USD $300,000. To follow TDN, please click the following link: https://www.bitforex.com/en/spot/tdn_btc. No TDN will be issued to the Company until the equipment arrives from China and the processing plant is in production.

Arno Brand, Co-CEO, stated: "These have been trying times for the Company as it progresses its efforts to evolve from a junior exploration company to a mining company. The achievements of those that have sacrificed their time in making it a reality will not go unnoticed. The Company is still in a very strong position as it has built its operations without having to fall on the assistance of an abusive debt transaction that will impede its profitability and damage shareholder value going forward. I am proud of our team for their patience and hard work as we wait for our mining license. I would further like to thank all the shareholders for their continued support."

Risk Factors

No mineral resources, let alone mineral reserves demonstrating economic viability and technical feasibility, have been delineated on the Aukam Property. The Company is not in a position to demonstrate or disclose any capital and/or operating costs that may be associated with satisfying the terms of the TODAQ Supply Agreement.

Gratomic wishes to emphasize that Supply Agreement is conditional on Gratomic being able to bring the Aukam project into a production phase, and for any graphite being produced to meet certain technical and mineralization requirements.

Gratomic continues to move its business towards production and as part of its business plan, expects to obtain a National Instrument 43-101 Standards of Disclosure for Mineral Projects technical report to help it ascertain the economics of Aukam. Presently the Company uses its existing pilot processing facility to produce certain amounts of graphite concentrate from accumulated surface graphite.

The Company advises that it has not based its production decision on even the existence of mineral resources let alone on a feasibility study of mineral reserves, demonstrating economic and technical viability, and, as a result, there may be an increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with developing a commercially mineable deposit.

The Supply Agreement provides that if Gratomic is unable to deliver graphite in accordance with the orders from Todaq, Todaq has the right to refuse to take any subsequent attempt to fulfill the order, terminate the agreement immediately, obtain substitute product from another supplier and recover from the Company any costs and expenses incurred in obtaining such substitute product or suing for damages under the contract.

Historically, such projects have a much higher risk of economic and technical failure. There is no guarantee that production will begin as anticipated or at all or that anticipated production costs will be achieved.

Failure to commence production would have a material adverse impact on the Company's ability to generate revenue and cash flow to fund operations. Failure to achieve the anticipated production costs would have a material adverse impact on the Company's cash flow and future profitability.

Steve Gray, P.Geo. has reviewed and approved the scientific and technical information in this press release and is Gratomic's "Qualified Person" as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects.
