In recent years, perovskite solar cells (PSCs) have been considered as one of the most promising photovoltaic technologies due to their solution processing, cost effectiveness, and excellent performance. The highest certified power conversion efficiency (PCE) achieved to date is 25.8%, which is approaching the best PCE of 26.81% achieved for silicon-based cells. However, perovskite materials are susceptible to various aging stressors, such as humidity, oxygen, temperature, and electrical bias, which hinder the industrialization of perovskite photovoltaic technologies. In this review, we discuss the lifetime of PSCs from the perspective of corrosion science. On one hand, benefiting from a series of anti-corrosion strategies (passivation, surface coating, machining ) used in corrosion science, the stability of perovskite devices is remarkably enhanced; on the other hand, given that perovskites are soft crystal lattices, which are different from traditional metals, the revealed degradation processes and specific methods to improve device operation stability can be applied to the field of corrosion, which can enrich and expand corrosion science.
近年来，由于钙钛矿太阳能电池（PSCs）具有溶液处理、成本效益高和优异性能等优点，被认为是最有前途的光伏技术之一。迄今为止，最高认证的功率转换效率（PCE）为 25.8%，接近硅基电池达到的 26.81%的最佳 PCE。然而，钙钛矿材料容易受到各种老化应力源的影响，如湿度、氧气、温度和电偏置，这阻碍了钙钛矿光伏技术的工业化。在这篇综述中，我们从腐蚀科学的角度讨论了 PSCs 的寿命。一方面，得益于腐蚀科学中使用的一系列耐腐蚀策略（钝化、表面涂层、机械加工），钙钛矿器件的稳定性得到了显著提高；另一方面，由于钙钛矿是软晶格，与传统金属不同，揭示的降解过程和提高器件运行稳定性的具体方法可以应用于腐蚀领域，从而丰富和扩展腐蚀科学。
