Routes toward Long-Term Stability of Mixed-Halide Perovskites
Matter , Volume 2 - Issue 4 p. 800- 802
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.
