Considerable efforts are being made to advance inverted (p–i–n) perovskite solar cells (PSCs). Several passivation and insulation strategies have effectively been applied to reduce non-radiative recombination, a notorious issue for PSCs. Consequently, the performance of inverted PSCs has begun to rival those of regular (n–i–p) PSCs, with power conversion efficiency (PCE) values above 26%. The efficiency of tandem solar cells containing an inverted PSC as a subcell has also grown rapidly, reaching >33%. This Review discusses the origin of non-radiative recombinations in PSCs and recent progress in reducing them. We review how innovative device configurations, perovskite composition and interfacial engineering contribute to the high efficiency and long-term operational stability of inverted PSCs. We aim to provide readers with important insights into materials chemistry, physical processing and device configurations to further improve perovskite-based photovoltaics.

人们正在付出相当大的努力来推进倒置 （p-i-n） 钙钛矿太阳能电池 （PSC）。几种钝化和绝缘策略已被有效地应用于减少非辐射复合，这是 PSC 的一个臭名昭著的问题。因此，倒置 PSC 的性能已开始与常规 （n-i-p） PSC 相媲美，功率转换效率 （PCE） 值超过 26%。包含倒置 PSC 作为子电池的叠层太阳能电池的效率也迅速提高，达到 >33%。本综述讨论了 PSC 中非辐射重组的起源以及减少它们的最新进展。我们回顾了创新的器件配置、钙钛矿组成和界面工程如何有助于倒置 PSC 的高效率和长期运行稳定性。我们的目标是为读者提供有关材料化学、物理加工和器件配置的重要见解，以进一步改进基于钙钛矿的光伏。
