主　　题：Lead iodide Residue Regulation Perovskite solar cells Efficiency Stability 

摘      要：Lead iodide(PbI2) is a vital raw material for preparing perovskite solar cells(PSCs),and it not only takes part in forming the light absorption layer but also remains in the grain boundary as a *** other words,the PbI2 content in the precursor and as formed film will affect the efficiency and stability of the *** moderate residual PbI2,it passivates the bulk/surface defects of perovskite,reduces the interfacial recombination,promotes the perovskite stability,minimizes the device hysteresis,and so *** PbI2 residue will reduce the interfacial passivation effect and device *** addition to facilitating the non-radiative recombination,over PbI2 residue can also lead to electronic insulation in the grain boundary and deteriorate the device ***,the impact and regulation of PbI2 residue on the device performance and stability is still not fully ***,a comprehensive and detailed review is presented by discussing the PbI2 residue impact and its regulation strategies(i.e., elimination,facilitation and conversion of the residue PbI2) to manipulate the PbI2 content,distribution and ***,we also show future outlooks in this field,with an aim to help further the progression of high-efficiency and stable PSCs.
