Excess Pbl2 evolution for triple-cation based perovskite solar cells with 21.9％efficiency
文献摘要：
The triple cation mixed perovskites(CsFAMA)are known as one of the most efficient candidates for per-ovskite solar cells(PSCs).It is found that the power conversion efficiency(PCE)of triple-cation based devices would increase with the test time extending,and the maximum efficiency is normally obtained after several days aging storage.Here,the relationship between enhanced device performance,excess Pbl2 and its evolution in triple cation perovskite films of initial days was systematically explored.The CsFAMA-PSCs are prepared by two-step methods under two environmental conditions,including in the glove box and the ambient air(30％humidity).After 7 days testing,the maximum PCE of PSCs under two conditions dramatically increased 12.4％and 12.2％,reached 21.68％and 21.89％,respectively.At ini-tial days,the XRD peak intensities of perovskite phase gradually decreased and those corresponding to Pbl2 increased.Along with time-resolved photoluminescence(TRPL)and kelvin probe force microscopy(KPFM),it was found that the defects were passivated with the evolution of Pbl2.This work reveals the excess Pbl2 and its evolution in perovskite film,which can further supplement the understanding of Pbl2 defect passivation.
