Abstract

original image

Solution-processable functionalized graphene (SPFGraphene, see figure) is used as the electron-accepting material in organic photovoltaic (OPV) devices for the first time, showing that it is a competitive alternative. The fabrication and performance of bulk heterojunction OPV devices with SPFGraphene and different donor materials is presented, together with the impact of post-fabrication annealing.
