Abstract

Abstract : In article number1700214, Baomin Xu, Chun Cheng and co‐workers fabricate high quality perovskite fi lms by blade coating lead acetate trihydrate sourced precursor solution under harsh ambient conditions. The hydrate water isolates moisture in ambient conditions and forms a quasi‐liquid nutrition pool for the cultivation of MAPbI3 grain domains via Ostwald ripening. As a result, highly oriented grain domains up to 100 μm are achieved after a low‐temperature, short time annealing treatment. The solar cells based on these printable perovskite fi lms give a champion effi ciency of 16.4% with negligible hysteresis.
