Tin‐based perovskite is a competitive analog with lead halide perovskite, but there are significant gaps in power conversion efficiency (PCE) and stability between tin‐ lead‐based solar cells. The characteristics of the easy oxidizability Sn 2+ rapid crystal growth for tin‐based two major issues remained to be overcome. Herein, an additive (4‐pyridylamidoxime (4‐PyAO)) multiple functional groups introduced precursor solution. oxidation crystallization rate both retarded by 4‐PyAO addition. prepared film high quality fewer trap states carrier recombination, extraction transfer adjacent transport layer also become more efficient. As result, corresponding devices deliver highest PCE 9.02%, accompanied short‐circuit current density, open‐circuit voltage, fill factor 19.90 mA cm −2 , 0.63 V, 72.48%, respectively. More importantly, best device without encapsulation maintains 92% its initial after 2500 h aging test nitrogen atmosphere, which may attributed synergic effect among different groups.

As an alternative technology to the standard evaporated metal top electrode in perovskite solar cells, transfer method is featured with low cost, simple process, and ease of scalability. However, as preparation less expensive electrodes (Ag Cu) explored, mismatch between hole‐transport layer results anomalous photovoltaic properties. In this study, work function hole‐transporting material adjusted by changing dopant content achieve a good energy‐level match either Ag or Cu material. The power conversion efficiencies devices based on transferred can reach 18.41% 17.25%, respectively, which are comparable performance devices.
