Improved efficiency and stability of Pb–Sn binary perovskite solar cells by Cs substitution
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 MA0.9Cs0.1Pb0.5Sn0.5I3 device can achieve a high efficiency of 10.07% with better thermal and ambient stability than the pristine MAPb0.5Sn0.5I3 device (6.36%).
