Posted October 01, 2018 09:05:01A new generation of graphene oxide nanoparticles with the potential to be used as a replacement for conventional solar cells has been discovered by researchers in a study published in Nature Communications.
Led by Professor Michael Sacks, the team used the graphene oxide produced by the graphene-based photocatalysis process to make a thin film of the metal.
The film was then sandwiched between layers of copper and glass, forming a semiconductor structure that was a little bigger than a postage stamp.
The researchers say that the new graphene oxide material, which is very thin, can be scaled up to several micrometers and can be fabricated on a silicon substrate.
The team says that this new material is suitable for use in photovoltaic cells and could be used to produce photovolcanoes, batteries, and solar cells, which would be useful for a wide range of applications from energy storage to solar arrays and other devices.
This new material, dubbed graphene-sulfur-polymer (GSP) graphene oxide, has the potential for widespread use as a thin-film photocatalyser.
The GSP graphene oxide film can be grown to about 100 micrometres (millionths of a meter) and is composed of a layer of graphene, with a layer and a half of sulfur oxide.”GSP graphene-silicon is a flexible material that can easily be fabricated into a flexible, conductive material,” Professor Sacks said.
“This new graphene-rich material is very flexible, which allows us to create films of up to 100 micron in size.”
Professor Sacks and his colleagues describe the graphene as a flexible sheet with many useful applications.
“In the near future, graphene-polymers may be used for many applications,” he said.
“GSP can be useful in a wide variety of applications, including photovacuum-based power generation, solar energy storage, solar cells and solar-powered vehicles.”GSP has a broad range of properties, including good electrical conductivity, good thermal conductivity and high mechanical strength.
The research team also used the material to make photovolaris batteries, which could be useful to use as batteries for electric vehicles.
The graphene-material-based materials could also be used, the researchers say, in photostatic cells that use solar energy to charge the batteries.
In a paper published in the journal Nature Communications, the scientists describe a variety of graphene-derived photocatlas which they have produced using the graphene process.
“The materials we developed are excellent at the formation of graphene sheets, and we are working on developing graphene oxide sheets as well,” Professor Anthony Gattis, who is the paper’s senior author, said.
The paper is titled: “High-performance graphene oxide photovolemic materials based on graphene oxide semiconducting nanocomposites”.
The researchers describe their research in their paper, and they plan to apply their graphene-like process for the production of more advanced graphene- and graphene-metal-based photovolesms.
The scientists said that they have already successfully applied graphene-pigment-based solar cells to demonstrate that the graphene/silicon process is suitable to produce solar cells that are as efficient as silicon photovolasms.
Professor Gatts said the team is continuing to work with the materials researchers to further improve the material’s ability to form photocataps and to use it in photodetectors, which use graphene as the basis of a photocatacitive layer.
“We have demonstrated that the nanocomposition of graphene is capable of forming solar cell layers that are approximately 100 microns thick,” he told TechRadar.
“These are very good photocatapulmonary materials that we hope to be able to use in the next generation of solar cells.”
“Graphene-based polymers are a promising alternative to silicon-based semiconductors in the semiconductor industry.”
Grapheme is a compound that is made from the amino acids glycine and aspartic acid.
It is used to make synthetic drugs and other organic materials.
