Abstract Over the past decade, organic-inorganic metal halide perovskite solar cells (PSCs) have skyrocketed to a certified power conversion efficiency (PCE) of 25.2%. Unfortunately, the instability of perovskite impedes the commercial development of PSCs in the long run when exposing to continuous illumination, moisture and high temperature. With recent progress in smart self-healing materials, empowering perovskite solar cells with self-healing capability has become a promising way to efficaciously improve the device long-term stability and durability. Herein, this article reviews recent advances in self-healing performance of perovskite solar cells. Self-healing types of perovskite films are outlined and the self-healing mechanism among perovskite solar cells are systematically discussed. Finally, an outlook on the challenges and prospects of self-healing perovskite solar cells was proposed and analyzed. This review provided a promising pathway for self-healing perovskite solar cells with durable stability.

自修复钙钛矿太阳能电池

摘要 在过去十年中，有机-无机金属卤化物钙钛矿太阳能电池 (PSC) 的认证功率转换效率 (PCE) 已飙升至 25.2%。不幸的是，钙钛矿的不稳定性在长期暴露于连续光照、潮湿和高温时阻碍了 PSC 的商业发展。随着智能自愈材料的最新进展，使钙钛矿太阳能电池具有自愈能力已成为有效提高器件长期稳定性和耐久性的有前途的方法。在此，本文回顾了钙钛矿太阳能电池自愈性能的最新进展。概述了钙钛矿薄膜的自修复类型，并系统地讨论了钙钛矿太阳能电池之间的自修复机制。最后，提出并分析了自修复钙钛矿太阳能电池的挑战和前景。该综述为具有持久稳定性的自修复钙钛矿太阳能电池提供了一条有前途的途径。
