High quality freestanding pristine graphene (PG) and boron-doped graphene (BG) were prepared by a novel and versatile method. BG is more conductive than PG due to a larger density of state generated near the Fermi level. Using BG as a back electrode, we achieved improved hole-collecting ability and photovoltaic efficiency for CdTe solar cells.
