The defects in perovskite films are one of the most non‐negligible factors that can attenuate the performances of perovskite solar cell. This work fabricates defect‐reduced perovskite film by using the lead indicator (dithizone) as an additive of perovskite functional layer. The dithizone can retard the crystallization rate of perovskite films, passivate the defects, and enhance the structure stability of perovskite by coordinating with lead atoms. As a result, the device doped with dithizone yields outstanding power conversion efficiency and stability.
