Abstract
Herein, the correlation between crystallization and external factors (solubility and solvent evaporation rate) is conducted for solution-processed CsPbI2Br film. With moderate precursor solution temperature, homogenous, pinhole-free, large crystalline grain size and thick CsPbI2Br film was obtained, which effectively increased the light absorption, and decreased recombination loss. As a result, the optimized champion device achieved long-term stabilized PCE of 14.81%.183
