CsPbBr(3) has received more and more attention in the field of optoelectronic devices due to its excellent stability. To address the cost and environmental concerns associated with the use of toxic methanol, water has been explored as a substitute solvent for CsBr in the preparation of CsPbBr(3) perovskite solar cells (PSCs). In this study, we utilized methanol as an anti-solvent of the CsBr/H(2)O solution to regulate the detrimental effects of water on the CsPbBr(3) film and control the crystallization process. From results of the experiment, it was found that methanol anti-solvent treatment ...
