Perovskite solar cells have made significant strides in recent years. However, there are still challenges in terms of photoelectric conversion efficiency and long-term stability associated with perovskite solar cells. The presence of defects in perovskite materials is one of the important influencing factors leading to subpar film quality. Adopting additives to passivate defects within perovskite materials is an effective approach. Therefore, we first discuss the types of defects that occur in perovskite materials and the mechanisms of their effect on performance. Then, several types of additives used in perovskite solar cells are discussed, including ionic compounds, organic molecules, polymers, etc. This review provides guidance for the future development of more sustainable and effective additives to improve the performance of solar cells.
近年来，钙钛矿太阳能电池取得了重大进展。然而，钙钛矿太阳能电池在光电转换效率和长期稳定性方面仍存在挑战。钙钛矿材料中缺陷的存在是导致薄膜质量不佳的重要影响因素之一。采用添加剂钝化钙钛矿材料中的缺陷是一种有效方法。因此，我们首先讨论钙钛矿材料中出现的缺陷类型及其对性能影响的机制。然后，讨论了钙钛矿太阳能电池中使用的几种添加剂，包括离子化合物、有机分子、聚合物等。本综述为未来开发更可持续、更有效的添加剂以提高太阳能电池性能提供了指导。
