Abstract ：ZnO nanorods are passivated with a TiO2 interfacial layer prepared by the atomic layer deposition method and applied in the CH3 NH3 PbI3 perovskite solar cell, which show a positive effect on the fill factor and power conversion efficiency. With TiO2 interfacial passivation, the charge recombination in the ZnO/CH3 NH3 PbI3 interface is effectively suppressed and the maximum power conversion efficiency is enhanced from 11.9% to 13.4%.
