The graphene and 'a material that is obtained in the laboratory from the graphite, and consists of a monatomic layer of carbon atoms, or has very thin thickness equal to that of a single carbon atom. Of graphene have long been known of his property, 'the conductor, and has also been made to the graphene transistor with a frequency double than in silicon.
Now thanks to a study by the USC (University of Southern California) on graphene will be able to 'be used for the construction of photovoltaic cells . What is
this? The photovoltaic cells are cells that use carbon chemistry as an alternative to traditional silicon cells. Research on them and 'active for some time, and the purpose and' to create a PV even more 'green and more' flexible.
Graphene should serve to create a transparent and flexible film suitable for coating the organic solar cells.
still can not 'talk about a real revolution, because the cells have an efficiency very low in carbon compared to silicon, but on the other hand' the organic cells are much more 'flexible use and have a much lower cost, and of course even less environmental impact.
So far, practical applications are not entirely predictable, but for example, thanks to this film in graphene will 'create a polymer can be used on clothes (to get enough energy to ricare phones, for example) but also on camping tents for a bit 'of energy wherever you go.
The properties' of graphene have been known for several decades, but it 's only since 2004 that has' begun to study the possible applications in as soon as it was difficult to obtain good quality graphene and work' in bulk '. Who knows 'so what other interesting applications will be able' to have this material.
