Perovskite solar cells have achieved power-conversion efficiency values approaching those of established photovoltaic technologies, making the reliable assessment of their operational stability the next essential step towards commercialization. Although studies increasingly often involve a form of stability characterization, they are conducted in non-standardized ways, which yields data that are effectively incomparable. Furthermore, stability assessment of a novel material system with its own peculiarities might require an adjustment of common standards. Here, we investigate the effects of different environmental factors and electrical load on the ageing behaviour of perovskite solar cells. On this basis, we comment on our perceived relevance of the different ways these are currently aged. We also demonstrate how the results of the experiments can be distorted and how to avoid the common pitfalls. We hope this work will initiate discussion on how to age perovskite solar cells and facilitate the development of consensus stability measurement protocols.

钙钛矿太阳能电池的功率转换效率值已接近已建立的光伏技术，因此，对其运行稳定性进行可靠评估是迈向商业化的下一个重要步骤。尽管研究越来越多地涉及稳定性表征的一种形式，但它们是以非标准化的方式进行的，所产生的数据实际上是无法比拟的。此外，对具有自身特性的新型材料系统的稳定性评估可能需要调整通用标准。在这里，我们研究了不同环境因素和电负载对钙钛矿太阳能电池老化行为的影响。在此基础上，我们评论了我们认为这些方法老化的相关性。我们还演示了如何扭曲实验结果以及如何避免常见的陷阱。我们希望这项工作将引发有关如何老化钙钛矿太阳能电池的讨论，并促进共识稳定性测量协议的发展。
