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.
