Anti-solvent processing was used for fast crystallization of perovskite precursor film, which can form dense perovskite film.However, the crystals from this method are usually small due to the fast crystal growth process, which could lead to grain boundary recombination. Here, element chloride is introduced to enhance the perovskite layer crystallinity via slowing down the perovskite crystallization process by simultaneous introduction of methylammounium chloride(MACl) and cesium chloride(CsCl) into precursor solution.As a result, we achieve high quality of pin-hole free perovskite film with large crystal size. A power conversion efficiency of 21.55% with free of hysteresis of the device is obtained, which is among the highest efficiency of planar structure perovskite solar cells. 关键词：太阳能电池氯化物电影质量添加剂多重生长过程晶化过程
