摘要
铅卤钙钛矿薄膜在光伏领域中展现出显著的应用潜力.然而,其商业化进程仍面临稳定性问题的挑战.近年来,铅卤钙钛矿薄膜的晶格应变逐渐受到广泛关注.研究表明,晶格应变不仅直接影响铅卤钙钛矿薄膜的能带宽度、载流子迁移率和缺陷形成能量,还可能引发薄膜降解.因此,调控晶格应变被视为提升铅卤钙钛矿薄膜性能与稳定性的有效策略.本文综述了近年来在铅卤钙钛矿薄膜晶格应变调控方面的研究进展,重点讨论了不同调控方法对铅卤钙钛矿薄膜及其光伏器件的性能和稳定性的影响,并对未来的研究方向进行了展望.
Abstract
Lead halide perovskite films have demonstrated significant potential in photovoltaic applications.However,their commercialization is still challenged by issues of stability.In recent years,lattice strain in lead halide perovskite films has garnered increasing attention.Research indicates that lattice strain not only directly affects the band gap,carrier mobility,and defect formation energy of lead halide perovskite films but may also induce film degradation.Thus,controlling lattice strain is considered an effective strategy to enhance the performance and stability of lead halide perovskite films.This paper reviews the recent advancements in the control of lattice strain in lead halide perovskite films,focusing on the impact of various control methods on the performance and stability of these films and their photovoltaic devices.Future research directions are also discussed.
