Abstract

Forward bias voltage is utilized to regulate ion migration in perovskite solar cells（PSCs）, thereby preventing the accumulation of perovskite ions at the interface, passivating defects, and restoring the performance of aged PSCs. The power conversion efficiency （PCE） of the aged PSCs is restored from 17.8% to 21.5% by implementing the forward bias voltage repair method. Introducing the bias voltage repair method in the maximum power point tracking for 100 hours yielded a total energy gain of 3.1%. An independently constructed integrated characterization environment was used to measure the real-time changes in the electrical and optical characteristics of PSCs before and after the repair process using bias voltage. Furthermore, a physical model was developed to investigate the mechanism behind the repair process, specifically focusing on the regulation of perovskite ion migration by bias voltage. The results demonstrate that the repairing strategy can control ion migration, passivate defects, optimize carrier extraction and transport, and ultimately repair the PSCs.
