主　　题：Graphene Heterojunction Solar cell 

摘      要：Graphene-on-semiconductor has been proved to be a quality heterojunction with efficient photoelectric conversion.In this work,we constructed Schottky junction solar cells by combing graphene woven fabrics(GWFs)and n-doped single crystal silicon,and examined the performance of solar cells when GWFs of different meshes were used.Sparse GWFs possessed high optical transparency but led to poor carrier collection,whereas dense GWFs could collect carriers efficiently but generated too few photo carriers due to low transparency.The GWFs with an optimal mesh could provide a good balance between the generation and collection of photo-induced carriers to deliver high power conversion efficiency.
