Doping leads to new efficiency record for graphene solar cells

Doping graphene with trifluoromethanesulfonyl-amide (TFSA) has enabled researchers at the University of Florida (UF) to set a new efficiency record for graphene solar cells. While the record-breaking efficiency of 8.6 percent is well short of the efficiencies seen in other types of solar cells, it is a big improvement over previous graphene solar cells that saw efficiencies ranging up to 2.9 percent. The development provides hope for cheaper, durable graphene solar cells in the future.
