摘要

在这篇简短的综述中，我们将讨论在更好地理解混合成分金属卤化物包晶材料中的偏析现象以及与之密切相关的离子迁移现象（发生在单相和混合包晶中）方面的最新进展。我们尤其关注这些现象的电化学方面，因为它们与设备的运行稳定性尤为相关。我们简要概述了抑制偏析/离子迁移的方法，随后总结了包晶体太阳能电池和包晶体发光二极管的稳定性里程碑。最后，讨论了未来的展望和挑战。

Metal halide perovskites: stability under illumination and bias

In this short review, we discuss recent progress in developing better understanding of the segregation in mixed composition metal halide perovskite materials and the closely related phenomenon of ion migration (which occurs in both single phase and mixed perovskites). We focus in particular on electrochemical aspects of these phenomena, since they are particularly relevant for the operational stability of devices. A short overview of the methods to suppress segregation/ion migration is given, followed by a summary of the stability milestones in perovskite solar cells and perovskite light emitting diodes. Finally, future outlooks and challenges are discussed.
