Metal halide perovskites exhibit remarkable properties for optoelectronic applications, yet their susceptibility to ion migration poses challenges for device stability. Previous research has predominantly focused on the migration of the halide ions. However, the migration of cations, which also has a significant influence on the device performance, is largely overlooked. In this Perspective, we review the migration of cations and their impacts on perovskite materials and devices. Special attention shall be devoted to recent insights into the migration of L-site organic cations in 2D/3D perovskites. We outline inspirations and directions for further research into the cation migration of perovskites, highlighting new possibilities in advancing perovskite optoelectronics.

卤化铅钙钛矿中的离子迁移：阳离子很重要

金属卤化物钙钛矿在光电应用中表现出卓越的性能，但它们对离子迁移的敏感性给器件稳定性带来了挑战。先前的研究主要集中在卤化物离子的迁移上。然而，阳离子的迁移对器件性能也有重大影响，但却在很大程度上被忽视了。在本视角中，我们回顾了阳离子的迁移及其对钙钛矿材料和器件的影响。应特别关注对 2D/3D 钙钛矿中 L 位有机阳离子迁移的最新见解。我们概述了进一步研究钙钛矿阳离子迁移的灵感和方向，强调了推进钙钛矿光电子学的新可能性。
