Graphene and its derivatives have been used in perovskite solar cells because of their excellent optical, electrical and flexible properties. The stability and photoelectric conversion efficiency of devices can be improved by adding graphene or graphene derivatives. This paper mainly introduces the application progress of graphene and its derivatives in perovskite solar cells. It may provide reference for the future to develop high performance and high stability devices by exploring the application of graphene and its derivatives in perovskite solar cells.
