Abstract

Cs substitution was applied to Pb–Sn alloy perovskites to retard the fast crystallization rate. As a result, the derived device performance and stability can be effectively improved. The representative MA_0.9Cs_0.1Pb_0.5Sn_0.5I₃ device can achieve a high efficiency of 10.07% with better thermal and ambient stability than the pristine MAPb_0.5Sn_0.5I₃ device (6.36%).
