This review article examines the current state of understanding in how metal halide perovskite solar cells can degrade when exposed to moisture, oxygen, heat, light, mechanical stress, and reverse bias. It also highlights strategies for improving stability, such as tuning the composition of the perovskite, introducing hydrophobic coatings, replacing metal electrodes with carbon or transparent conducting oxides, and packaging. The article concludes with recommendations on how accelerated testing should be performed to rapidly develop solar cells that are both extraordinarily efficient and stable.

了解钙钛矿光伏电池的降解机理并提高其稳定性

这篇评论文章探讨了目前对金属卤化物钙钛矿太阳能电池在暴露于湿气，氧气，热量，光线，机械应力和反向偏压时如何降解的认识。它还强调了提高稳定性的策略，例如调整钙钛矿的组成，引入疏水涂层，用碳或透明导电氧化物代替金属电极以及包装。本文最后提出了有关如何进行加速测试以快速开发既高效又稳定的太阳能电池的建议。
