| Abstract |
Inspired by nature, intelligent self-healing materials have recently been exploited also in the field of photovoltaics to mimic natural systems achieving self-repairing. The past decade has witnessed perovskite solar cells (PSCs) skyrocketing to a certified power conversion efficiency of 26.1%. However, their intrinsic instability, when exposing to moisture, high temperature, and continuous illumination, hampers their commercial development for a long-term use in ambient operating conditions. Therefore, the use of smart self-healing materials, based on self-assembling properties and dynamic interactions, empowers PSCs with self-recovery abilities to reinforce their pivotal role as efficient photovoltaic devices and encourage their exploitation in the market. Herein, the current progress in self-healing perovskite materials with a special focus on self-recovery after moisture exposure or mechanical damage with the aim to provide a valuable insight for research on this topic to accelerate the PSC commercialization process is highlighted. |
