Antisolvent-assisted growth of inorganic CsPb(Br,I)3 under ambient conditions

Abstract

Controlling the growth of halide perovskite films under high relative humidity (RH) ambient conditions is significant for practical applications. Here, we control the antisolvent-assisted growth reactions with a constant temperature and low RH. With the hot casting setup and antisolvent during growth reactions, the synthesis of high coverage and pinhole-free CsPb(Br,I)₃ films is achieved in ambient air.
