Potential applications for solar energy?
The very first application where graphene is going to be used is probably as a replacement for (the relatively expensive metal) indium selenide in solar cells. Research indicates that graphene is probably going to be massively adopted in the marketplace in a few years. -- CNN
Graphene is a two dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb or chicken wire structure. It is the thinnest material known and yet is also one of the strongest. It conducts electricity as efficiently as copper and outperforms all other materials as a conductor of heat. Graphene is almost completely transparent, yet so dense that even the smallest atom helium cannot pass through it. (ref)
"I am completely convinced that graphene is going to end up changing our lives. Exactly how, I don't know and I don't think anyone can know for sure but there is nothing thinner, stronger or more suitable to conduct electricity and that has to be useful for many important things." A statement from Tomás Palacios to CNN. Tomás is the Emmanuel E. Landsman Career Development Associate Professor of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT) -- CNN
