Solution-processed small-molecule solar cells are demonstrated by insertion of graphene quantum dots (GQDs). The GQDs play an important role in increasing current density and fill factor which correlate with improved EQE and effective surface morphology. The multiple scattering and a reduced charge transport resistance lead to enhanced performances.
