Highlights High quality and strongly oriented perovskite films are prepared by two step doctor blading in air. Methylammonium chloride induced low dimensional intermediate phase regulates the crystallization and orientation of the perovskite. Two step doctor bladed perovskite solar cells achieve a power conversion efficiency (PCE) of 23.14%, while 1.03 cm2 PSCs and 10.93 cm2 mini modules achieve PCEs of 21.20% and 17.54%, respectively.
