Correlated alkyl chain length to defect passivation efficacy in perovskite solar cells

Abstract

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