Abstract | Techniques for increasing conductivity of graphene films by chemical doping are provided. In one aspect, a method for increasing conductivity of a graphene film includes the following steps. The graphene film is formed from one or more graphene sheets. The graphene sheets are exposed to a solution having a one-electron oxidant configured to dope the graphene sheets to increase a conductivity thereof, thereby increasing the overall conductivity of the film. The graphene film can be formed prior to the graphene sheets being exposed to the one-electron oxidant solution. Alternatively, the graphene sheets can be exposed to the one-electron oxidant solution prior to the graphene film being formed. A method of fabricating a transparent electrode on a photovoltaic device from a graphene film is also provided. |
