▎ 摘　　要

NOVELTY - Increasing conductivity of a graphene film, comprises forming the graphene film from one or more graphene sheets; and exposing the graphene sheets to a solution comprising a one-electron oxidant configured to dope the graphene sheets to increase a conductivity thereof, thus increasing the overall conductivity of the film. USE - The method is used for increasing conductivity of a graphene film (claimed). ADVANTAGE - Improved techniques for reducing the sheet resistance of transparent graphene films are provided. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are: (1) a graphene film having increased conductivity prepared by the method above; and (2) a method of fabricating a transparent electrode on a photovoltaic device from a graphene film.
