The application of interface modification in improving the stability of perovskite solar cells

In recent years, perovskite solar cells (PSCs) have experienced rapid development, driven by their exceptional photovoltaic performance, remarkable power conversion efficiency, and straightforward fabrication processes. However, the issue of stability has remained a significant challenge hindering their commercialization. This article explores the effects of various environmental factors, including temperature, humidity, and light exposure, on the stability of PSCs, with a particular focus on the structural characteristics of the cells themselves. It further delves into the mechanisms that influence the stability of PSCs, reviewing recent advancements in areas such as the defect passivation of perovskite films and the optimization of energy levels within PSCs. The article concludes by offering an outlook on the ongoing trends in interface modification techniques for PSCs, aiming to enhance their long-term stability and enable their broader and more practical application in the future. Through these efforts, the commercialization and widespread use of PSCs could be significantly advanced.
