With the progress in the development of perovskite solar cells, increased efforts have been devoted to enhancing their stability. With more devices being able to survive harsher stability testing conditions, such as damp heat or outdoor testing, there is increased interest in encapsulation techniques suitable for this type of tests, since both device architecture compatible with increased stability and effective encapsulation are necessary for those testing conditions. A variety of encapsulation techniques and materials have been reported to date for devices with different architectures and tested under different conditions. In this Perspective, we will discuss important factors affecting the encapsulation effectiveness and focus on the devices, which have been subjected to outdoor testing or damp heat testing. In addition to encapsulation requirements for these testing conditions, we will also discuss device requirements. Finally, we discuss possible methods for accelerating the testing of encapsulation and device stability and discuss the future outlook and important issues, which need to be addressed for further advancement of the stability of perovskite solar cells.
随着钙钛矿太阳能电池开发的进展，人们已加大努力来提高其稳定性。随着越来越多的器件能够在诸如湿热或户外测试等更严苛的稳定性测试条件下存活，对于适用于此类测试的封装技术的兴趣日益浓厚，因为对于那些测试条件而言，既需要与提高稳定性兼容的器件架构，又需要有效的封装。迄今为止，针对具有不同架构的器件并在不同条件下进行测试，已报道了多种封装技术和材料。在本观点文章中，我们将讨论影响封装有效性的重要因素，并聚焦于已进行户外测试或湿热测试的器件。除了这些测试条件的封装要求外，我们还将讨论器件要求。最后，我们讨论加速封装和器件稳定性测试的可能方法，并讨论未来展望以及为进一步提高钙钛矿太阳能电池稳定性需要解决的重要问题。
