Abstract
En 中文
• A choline chloride–sulfamide (CSR) synergistic bimolecular engineering is developed to precisely regulate 1D perovskite growth on 3D perovskite surfaces for inverted solar cells. • Bimolecular interaction and defect passivation facilitate oriented 1D perovskite formation, eliminate residual PbI2, and refine energy level alignment. • The CSR-modified inverted perovskite solar cell achieves a champion efficiency of 25.30% with simultaneously improved VOC and fill factor. • Multifunctional interfacial engineering suppresses non-radiative recombination and enhances charge extraction at the perovskite/ETL interface. • The device exhibits outstanding stability, retaining 82.01% efficiency after 500 h thermal aging and 86% after 800 h MPP tracking.
