摘要: 金属卤化物钙钛矿材料因其优异的光电性能和可调控的晶体结构,在太阳能电池、发光二极管和光电探测器等领域展现出巨大的应用潜力。结构畸变作为调控钙钛矿材料性能的重要手段,能够显著影响其电子结构、载流子动力学和光电特性,为设计新型功能材料提供了重要途径。近年来,钙钛矿单晶的结构畸变调控研究取得了显著进展。通过改变基底特性、引入有机阳离子、调控卤素组成或施加外部应力,研究人员能够有效调节钙钛矿单晶的晶格对称性和电子能带结构,从而优化其光电性能。特别是,结构畸变对载流子动力学、激子行为和缺陷态密度的调控作用,为开发高性能钙钛矿器件提供了新的途径。本文首先阐述了钙钛矿材料结构畸变的表征方法与机理基础,随后详细分析了实验条件下诱发钙钛矿结构畸变的主要影响因素,进而深入探讨了结构畸变与材料光电性能的构效关系,为钙钛矿光电材料的结构畸变与性能调控提供了参考。

Abstract: Metal halide perovskite materials have demonstrated significant application potential in fields such as solar cells, light-emitting diodes, and photodetectors due to their excellent optoelectronic properties and tunable crystal structures. Structural distortion, as a crucial means of regulating the performance of perovskite materials, can significantly influence their electronic structure, carrier dynamics, and optoelectronic properties, providing an important pathway for designing novel functional materials. In recent years, research on the regulation of lattice distortion in perovskite single crystals has made remarkable progress. By altering substrate properties, introducing organic cations, modulating halide composition, or applying external stress, researchers can effectively adjust the lattice symmetry and electronic band structure of perovskite single crystals, thereby optimizing their optoelectronic performance. In particular, the regulatory effects of lattice distortion on carrier dynamics, exciton behavior, and defect state density offer new avenues for developing high-performance perovskite devices. This paper first elaborates on the characterization methods and mechanistic principles of structural distortions in perovskite materials, then thoroughly analyzes the key influencing factors that induce structural distortions under experimental conditions. Furthermore, it provides an in-depth discussion on the structure-property relationship between lattice distortions and optoelectronic performance, offering both theoretical foundations and practical guidance for structural distortion control and performance optimization of perovskite optoelectronic materials.
