This article introduces the method to fabricate a transparent graphene conductive film from graphite powder by a solution process. Chemically oxidized graphite powder was dispersed in water, and it was exfoliated by repeated centrifugation and washing processes to obtain graphene oxide (GO). Successively, a GO film was prepared by coating a transparent substrate with the GO solution, and it was chemically and thermally deoxidized to produce a transparent graphene conductive film. To date, organic thin film photovoltaic cells with the graphene transparent electrodes have shown the power conversion efficiency as high as 1.2 %. Novel application of GO to organic/inorganic heterojunction solar cells will be also presented.
