SOLUTION PROCESSED GRAPHENE THIN FILMS AND THEIR APPLICATIONS IN ORGANIC SOLAR CELLS

We present a review of the recent progresses in solution processing graphene thin films and highlight some of the uses of graphene and graphene thin films in the construction of organic solar cells. We demonstrate a simple phenomenological model to describe the relationship between sheet conductivity and transmittance in graphene films with good agreement to all of the data found in the literature. We show that graphene thin films have been proven useful in the construction and improvement of organic solar cells not only as a replacement electrode, but also as an active acceptor material, or as a counter electrode when integrated into a conducting polymer matrix.
