Enhancing open-circuit voltage in CH3NH3PbI3(Cl)perovskite solar cell has become a major challenge for approaching the theoretical limit of the power conversion efficiency.Here,for the first time,we demonstrate that the synergistic effect of PbI2 passivation and chlorine incorporation via controlling the molar ratio of PbI2,PbCl2(or MACl)and MAI in the precursor solutions,boosts the open-circuit voltage of CH3NH3PbI3(Cl)perovskite solar cell over 1.15 V in both mesoscopic and inverted perovskite solar cells.
