Ultrasmooth perovskite films are usually prepared by the solvent-engineering, fast-crystallization process, and/or Lewis base adduct approaches8,19–21. In all these one-step methods, high-quality perovskite or perovskite intermediate films were achieved by timely application of antisolvent such as ...
