Understanding the entropy-driven polymorphism of hybrid perovskites

Hybrid organic-inorganic perovskites (HOIP) such as MAPbI3 (MA = methylammonium, [CH3NH3]+) have attracted tremendous attention over the past years due to their excellent...混合有机-无机钙钛矿（Hybrid organic-inorganic perovskites, HOIP），例如甲胺铅碘（MAPbI3，其中MA代表甲胺阳离子[CH3NH3]+），在过去数年中凭借其优异的……特性引发了广泛关注。
