The power conversion efficiency (PCE) of organic–inorganic lead halide perovskite solar cells (PSCs) has exceeded 25%, approaching the best record of their silicon counterpart. However, lifetime issues still stand between PSCs and the goal of mass commercialization. For instance, most photoactive perovskites are hydrophilic, and moisture can quickly turn some of their constituents to compounds yielding trap states. Some perovskites are not thermally stable in the temperature window of solar cell operation and will transform into photo-inactive non-perovskites. If a perovskite is of an inadequate quality, e.g., vacancies, surface area, or grain boundaries per unit volume are high, there exist more defect sites, acting as migration pathways for perovskite ions under photo-bias, and the migration changes the perovskite's composition. An unstable perovskite/charge transport material (CTM) interface allows cross-contamination between molecules from both sides of the interface. Even without external stress, perovskite ions in an operating PSC undergo redox processes, which create defect states or initiate chemical chain reactions to accelerate PSC degradation. This mini-review discussed recent progress in solving issues, including the above, to stabilize PSCs with competitive PCE beyond 20%. The remarkable longevity of 15 PSCs under accelerated aging tests was probed in depth from three viewpoints: (1) perovskite compositions and dopants, (2) perovskite additives, and (3) CTMs. This mini-review, within which crucial perovskite-stabilizing methods were systematically analyzed, can be used as a quick-start guide when dealing with PSCs' stability in the future.

有机-无机卤化铅钙钛矿太阳能电池（PSC）的功率转换效率（PCE）已超过25％，接近其硅同类产品的最佳记录。但是，生命周期问题仍然存在于PSC和大规模商业化目标之间。例如，大多数光敏钙钛矿是亲水性的，水分会迅速将其某些成分转变为能产生陷阱态的化合物。某些钙钛矿在太阳能电池运行的温度范围内不是热稳定的，它们将转变为光敏非钙钛矿。如果钙钛矿的质量不足，例如每单位体积的空位，表面积或晶界很高，则存在更多的缺陷位点，充当光致偏压下钙钛矿离子的迁移途径，并且迁移会改变钙钛矿的成分。不稳定的钙钛矿/电荷传输材料（CTM）界面允许界面两侧的分子之间发生交叉污染。即使没有外部应力，运行中的PSC中的钙钛矿离子也会经历氧化还原过程，该过程会产生缺陷状态或引发化学链反应，从而加速PSC的降解。此小型审查讨论了解决上述问题的最新进展，以稳定具有竞争性PCE超过20％的PSC。从以下三个方面深入探讨了15种PSC在加速老化测试中的出色寿命：（1）钙钛矿成分和掺杂剂；（2）钙钛矿添加剂；（3）CTM。这份小型综述对系统关键的钙钛矿稳定化方法进行了系统地分析，可作为将来处理PSC稳定性时的快速入门指南。
