Applied bias photon-to-current conversion efficiency of ZnO enhanced by hybridization with reduced graphene oxide

140rGO-hybridization improved the charge transfer properties and suppressed defect-based recombination of ZnO, which increased the photocurrent density and applied bias photon-to-current efficiency (ABPE) from 0.55% (ZnO) to 0.95% (rGO/ZnO).
