With the rapid developments in lead halide perovskite solar cell technology, record-high power conversion efficiencies have been achieved, and significant research efforts have been directed toward stability, which is still a major challenge facing the commercialization of perovskite solar cell technology. In this review article, we review the research progress that has been made on the stability of perovskite solar cells. We start with an analysis of recently reported operational stability profiles of perovskite solar cells. On the basis of the analysis, we determine the solar cell lifetime (i.e., T₈₀ values) and the total amount of energy generated during the lifespan of a perovskite solar cell, from which several trends are inferred. In the subsequent sections, we further examine the instability issues associated with various constituents in a perovskite solar cell and the new methods/strategies that have been developed to solve these issues.

随着卤化钙钛矿太阳能电池铅技术的飞速发展，已经实现了创纪录的高功率转换效率，并且针对稳定性的研究也很多，这仍然是钙钛矿太阳能电池技术商业化所面临的主要挑战。在这篇综述文章中，我们回顾了钙钛矿太阳能电池稳定性方面的研究进展。我们从分析最近报道的钙钛矿太阳能电池的运行稳定性概况开始。在分析的基础上，我们确定了太阳能电池的寿命（即T ₈₀值）和钙钛矿型太阳能电池寿命期间产生的能量总量，由此可以推断出几种趋势。在接下来的部分中，我们将进一步研究与钙钛矿太阳能电池中各种成分相关的不稳定性问题，以及为解决这些问题而开发的新方法/策略。
