Abstract
Ascorbic acid was for the first time introduced as an effective antioxidant additive to enhance the efficiency and stability of Sn-based perovskite solar cells. It not only can effectively hinder the precursor solution of Sn-based perovskite from oxidation but modulate the Sn-based perovskite crystallization via forming associated intermediate complexes. A high PCE of 14.01% with improved stability can be finally realized in a MA0.5FA0.5Pb0.5Sn0.5I3 PVSC processed with AA additive, outperforming the value (12.18%) of the control device processed with the regular SnF2 additive.199
