Florida Researchers See Record Efficiency for Graphene in Solar Cells

Description University of Florida nanoresearchers report unprecedented power conversion efficiency with a new graphene-based solar cell.

Prior attempts at using graphene’s single-atom-thick honeycomb lattice in solar cells have shown power conversion efficiencies up to 2.9 percent. The UF team more than tripled those levels, with a record-breaking 8.6 percent efficiency. They achieved these results by chemically treating, or doping, graphene with trifluoromethanesulfonyl-amide, or TFSA.

The results are published in the current online edition of Nano Letters.
