摘　　要：In the past 10 years,perovskite solar cells(PSCs)have undergone extremely rapid development,with a record certified power conversion efficiency(PCE)of 26.7%,which is very close to the limit efficiency.However,the inherent instability caused by ion migration impedes the realization of long-term operationally stable PSCs.In this review,the types and mechanisms of ion migration occurring in various functional layers of negative-intrinsic-positive(n-i-p)PSCs are summarized.Additionally,methods of suppressing ion migration are systematically discussed.Finally,the prospects of current challenges and future development directions are proposed to advance the achievement of high-performance regular PSCs with high stability and PCE.
