Repair Strategies for Perovskite Solar Cells
In recent years, organic-inorganic hybrid halide perovskite solar cells(PSCs) have obtained rapid development due to their excellent optoelectronic properties and low fabrication cost. However, owing to the environmental sensitivity of perovskite materials, the instability of PSCs is the key issue hindering its commercialization. Developing feasible strategy to repair the degraded PSCs stands for effective and unique means to prolong the operational lifetime of PSCs. Herein, we summarize various methods to repair the degraded PSCs under the influence of different environmental conditions. Along with the repairing process, the optoelectronic properties of perovskite film as well as the corresponding PSCs are discussed. Some suggestions on how to further improve the intrinsic stability of perovskite and repairing effect of PSCs are also provided.
