Although the power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have made great progress, the surface and interface defects still affect their PCE and stability and hinder the commercialization. To overcome this problem, 1-methylimidazole (1-MIm) and 1-methylbenzimidazole (1-MBIm) were used as the interfacial passivation agents to passivate the defects at surface and interface. The results indicated that, in contrast to 1-MIm, 1-MBIm displayed a stronger Lewis coordination interaction with the uncoordinated Pb2+ to reduce the non-radiativ
