Graphene as a front contact for silicon-perovskite tandem solar cells

Oct 03, 2015

Researchers at the Helmholtz-Zentrum Berlin (HZB) developed a process for coating perovskite layers with graphene for the first time, so that the graphene acts as a front contact in silicon-perovskite tandem solar cells.

A traditional silicon absorber converts the red portion of the solar spectrum very effectively into electrical energy, whereas the blue portions are partially lost as heat. To reduce this loss, the silicon cell can be combined with an additional solar cell that primarily converts the blue portions and a particularly effective complement to conventional silicon is perovskite. However, it is normally very difficult to provide the perovskite layer with a transparent front contact. While sputter deposition of indium tin oxide (ITO) is common practice for inorganic silicon solar cells, this technique destroys the organic components of a perovskite cell.

Saint Jean Carbon receives NSERC research grant

Oct 03, 2015

Saint Jean Carbon logoSaint Jean Carbon, a publicly traded junior mining exploration company, has announced that it has secured a research grant from the Natural Sciences and Engineering Research Counsel of Canada (NSERC).

The grant covers the cost from the research and development work conducted at the University of Waterloo Applied Carbon Nanotechnologies Laboratory, where the company has been working on a number of projects, such as working towards creating superconducting room temperature graphene, using the patented sonicating method to better understand how to produce mass quantities of graphene and working toward building greater efficiencies in lithium battery grade materials.

A novel measurement technique could prevent defects in graphene

Oct 03, 2015

Researchers at Pennsylvania’s Lehigh University have reported a breakthrough in efforts to non-invasively characterize the properties of graphene. This work could potentially enable scientists to rapidly monitor levels of strain as graphene is being fabricated, thereby helping to prevent the formation of defects.

By using Raman spectroscopy, a technique that collects light scattered off a material’s surface, and statistical analysis, the scientists were able to take nanoscale measurements of the strain present at each pixel on the material’s surface and obtain a high-resolution view of the chemical properties of the graphene surface.

Haydale enters into a joint development and commercialization agreement with Scott Bader

Oct 03, 2015

Haydale logoHaydale announced that its composites division Haydale Composite Solutions (HCS) has entered into a joint development and commercialisation agreement with Scott Bader Company, a global supplier of liquid resins, gel coats and adhesives.  

Under the agreement, HCS will functionalize Graphene Nano Platelets utilising its proprietary HDPlas® process and add them to Scott Bader’s Crestapol resin to create a highly loaded masterbatch. This masterbatch will then be diluted down by Scott Bader and HCS into a range of concentrations from 1% to 8% and cast into resin plaques which will then be tested to quantify any improvements in mechanical, physical, electrical and thermal performance.

IBM swaps silicon for carbon nanotubes in transistors

Oct 03, 2015

IBM logoIBM scientists announced a remarkable engineering achievement - they have managed to exchange the silicon transistor contacts in transistors for smaller, more efficient, carbon nanotubes. This could have revolutionary potential as silicon is getting harder to shrink in size, while CNTs can allow a reduction in the size of transistors.

The smaller silicon transistor contacts get, the higher their electrical resistance becomes. There comes a point where the components simply get too small to conduct electrons efficiently and it seems that silicon is nearing that point. Carbon nanotubes, on the other hand, are a different story. They measure less than 10 nanometers in diameter (less than half the size of today's smallest silicon transistor contact) and IBM actually had to devise a new means of attaching these tiny components. Known as an "end-bonded contact scheme" the 10 nm electrical leads are chemically bonded to the metal substructure. Replacing these contacts with carbon nanotubes won't just allow for computers to crunch more data, faster. This breakthrough ensures that they'll continue to shrink, following Moore's Law, for several iterations beyond what silicon components are capable of.

Graphene-Info interviews NanoXplore's CEO, Dr. Soroush Nazarpour

Oct 01, 2015

Soroush Nazarpour PhotoGroup NanoXplore is a Montreal-based company specializing in the production and application of graphene and its derivative materials. The company's CEO and President, Dr. Soroush Nazarpour, was kind enough to answer a few questions we had regarding NanoXplore's technology and business.

Q: Hello Dr. Soroush. Can you update us on your current graphene material production and your new 3-ton GNP production facility?

Our Montreal production facility is running at full steam. Not only are we producing a full range of graphene materials, we are making more and more graphene-enhanced polymer products. In October we will be moving to a new facility, having outgrown our current space. The new facility will double our lab facilities and more than quadruple our production floor space.

We are seeing especially strong demand for graphene-enhanced plastics and rubber, with most customers focusing on improving mechanical and thermal characteristics. We have also seen a lot of emerging demand for coatings for textiles and other flexible substrates for thermal management, improved surface properties and protection.

Disappearing carbon circuits on graphene to possibly benefit security and biomedical applications

Sep 30, 2015

Researchers at the Georgia Institute of Technology used carbon atoms deposited on graphene with a focused electron beam process, to demonstrate a technique for creating dynamic patterns on graphene surfaces. The patterns could be used to make reconfigurable electronic circuits, which evolve over a period of hours before ultimately disappearing into a new electronic state of the graphene.

Beyond allowing fabrication of disappearing circuits, the technology could be used as a form of timed release in which the dissipation of the carbon patterns could control other processes, such as the release of biomolecules.
