Abstract

A simple surface treatment with N-methyl-1,3-propane diammonium diiodide (Me-PDAI₂) on top of 3D perovskite inducing the formation of a thin 3D (Me-PDA)Pb₂I₆ perovskitoid layer is reported, leading to smoother surface texture, longer charge-carrier lifetime, higher charge-carrier mobility, and reduced surface-defect density. With the perovskitoid surface modification, the device efficiency is improved from 20.3% to 22.0% along with enhanced stability. In addition, the perovskitoid surface engineering approach is applicable to different perovskite compositions.
