吡啶胺驱动的配位与氢键界面钝化实现高效钙钛矿太阳能电池
Pyridylamine-driven Interfacial Passivation via Coordination and Hydrogen Bonding Enables Efficient Perovskite Solar Cells
摘要
Abstract
Perovskite solar cells(PSCs)have garnered significant attention for their high efficiency,but their commer-cial application is hindered by stability issues caused by defects such as uncoordinated Pb2+ions and halide vacancies.This work introduces 3-amino-2,6-dichloropyridine(ADCP)as a novel pyridylamine additive for PSCs,aiming to en-hance both device efficiency and stability.ADCP features a pyridine functional group that coordinates with Pb2+ions and forms hydrogen bonds with halide ions,enabling dual-site passivation of defects.This dual interaction reduces Pb-related defects,improves crystallinity,and enhances charge transport within the perovskite layer.The devices exhibit a PCE of 25.59%,with significant improvements in long-term stability,maintaining 81%of the initial PCE for nearly 500 h.The study highlights the effectiveness of pyridylamine-driven passivation in overcoming stability issues and enhancing the over-all performance of PSCs,providing a promising strategy for high-efficiency,stable perovskite photovoltaics.关键词
