Finding an effective means of defect passivation is thought to be a promising route for bringing further increases in the power conversion efficiency and the open-circuit voltage (V OC ) of perovskite solar cells. They claim that the method ensured a power conversion efficiency of more than 9% in perovskite cells stored for a month in a water-saturated atmosphere. Al-Ashouri et al. February 7, 2019. However, a large energy loss results from the serious energy level offset of 1.05 eV between CsPbI2Br and Spiro-MeOTAD, hindering the further efficiency improvement of perovskite solar cells. In recent years, the power conversion efficiency of perovskite solar cells has increased to reach over 20%. Lead acetate (PbAc2) is stoichiometrically added in the mother solution consisting of methylammonium iodide (MAI) and lead iodide (PbI2) in 2-methoxyethanol (2ME), leading to MAPbI3 and byproduct methylammonium acetate (MAAc).
