Abstract
A layer-by-layer approach is developed to prepare uniform and compact CH₃NH₃PbI(3-x)Clx perovskite films for perovskite solar cells with a high efficiency up to 15.12% and an improved stability. Moreover, a record high efficiency of 12.25% is achieved for these flexible perovskite solar cells. This study represents an important step forward in developing high-performance and stable perovskite solar cells.
