Correlating alkyl chain length with defect passivation efficacy in perovskite solar cells
We, for the first time, correlated the alkyl chain length of amine molecules with the defect
passivation efficacy, either on the surfaces or at grain boundaries of perovskite films. Blade-
coated perovskite solar cells with long-chain amine passivation achieved an efficiency of
21.5%, accompanied by a small voltage loss of 0.35 V.
