文摘
On-fabrication solid-state N-doping of graphene is developed using a Zonyl-added ZnO layer on a graphene surface. Inverted organic solar cells based on the graphene cathode and the ZnO layer exhibit a power conversion efficiency of 7.5%—a high-record power conversion efficiency of single-junction organic solar cells with graphene electrodes. For the first time 100% power conversion efficiency with respect to the ITO cathode is achieved.
