Recently, much attention has been paid to solar cells based on inorganic perovskite materials. However, the quality and thickness of perovskite films are still unsatisfactory due to the limited solubility of the starting materials. Described here is a simple multiple coating process for fabrication high quality perovskite films under full air condition. Defects such as pinholes can be effectively eliminated by the second coating with a further increase in grain size, which significantly suppresses charge recombination in perovskite films. In addition, such film thickness can lead to improve the absorption of incident light. As a result, the traditional inverted planar perovskite solar cells achieve an energy conversion efficiency of 11.5% with significantly improved device parameters, which is 44% more than the control device (8%). In addition, the stability of the device is also improved by such high-quality multiple coated perovskite films. The results show that this multiple coating method is a promising choice for high strength and efficient perovskite solar cells.
