In the recent anniversary issue of Trends in Chemistry, Brennan et al. review halide segregation in mixed-halide perovskites, discussing multiple perspectives on the underlying origins and reported routes to retard halide segregation. Here, we argue that only slowing down the segregation may be insufficient to achieve long-term stability.

混合卤化物钙钛矿长期稳定性的途径

在最近的化学趋势周年纪念中，Brennan等。综述了混合卤化物钙钛矿中的卤化物偏析，讨论了有关潜在成因的多种观点，并报道了阻碍卤化物偏析的途径。在这里，我们认为仅放慢种族隔离可能不足以实现长期稳定。
