Abstract

. As a result, DEAET-treated devices show enhanced open-circuit voltages, reduced hysteresis, and improved stabilized power conversion efficiencies, approaching 19%. In addition, DEAET significantly enhances device stability, with treated solar cells retaining their initial performance for over 350 h under shelf-storage conditions and maintaining 80% of their initial PCE after more than 2 h of continuous operation under ISOS-L-1 conditions. The encouraging findings of this study lay the foundation for the utilization of tertiary ammonium-thiol-based salts as efficient agents for interface engineering in perovskite solar cells.
