Molecular Motion and Dynamic Crystal Structures of Hybrid Halide Perovskites,Hybrid halide perovskites are semiconductors with a twist. Their structures are highly dynamic with disorder occurring across a range of length and time scales. Herein, we discuss the atomic processes that underpin this behaviour and how they are linked to photovoltaic performance.沙发 发表于 2025-3-24 04:02:19
