摘要
高性能金属卤化物钙钛矿太阳能电池目前正从实验室研发向工业生产转型,并在未来全球能源领域展示了其不可估量的应用价值。为了实现高性能的金属卤化物钙钛矿太阳能电池,钙钛矿材料作为有源工作层,其性能的提高和优化过程经过了十几年,并已取得巨大的进步。本文以高性能卤化物钙钛矿中金属位铋离子掺杂的调制研究为重点,系统总结了卤化物钙钛矿薄膜的发展和常规制备工艺。研究表明,三元阳离子钙钛矿可以抑制黄相的形成、改变晶粒尺寸、提高稳定性等特点,成为未来高性能钙钛矿光电器件的首选。文章还对铋离子(Bi^(3+))掺杂钙钛矿体系进行了讨论,研究发现Bi3+的特殊电子结构和无毒化学性质,不仅能够提高钙钛矿的稳定性,还能灵活调控钙钛矿的光电性能,从而实现铋离子掺杂的高性能钙钛矿太阳能电池。结合目前卤化物钙钛矿太阳能电池的研究现状,我们可以预见在未来的器件优化过程中,可以将铋离子掺杂策略与三元混合阳离子钙钛矿相互结合。最后,我们展望了实现高性能金属卤化物钙钛矿太阳能电池的几个潜在研究方向。
High-performance metal halide perovskites solar cells are currently in the transi-tion from laboratory research to industrial production and have demonstrated their immeasur-able application value in the future global energy field.To achieve high-performance metal halide perovskite solar cells,the perovskite materials used as active working layers have undergone a decade-long optimization process resulting in significant progress.Focusing on the modulation research of metal-site bismuth ion doping in high-performance halide perovskites,this paper provides a systematic summary of the development and conventional preparation process of halide perovskites thin films.Researches have shown that ternary cationic perovskites can inhibit the formation of the yellow phase,change grain size,and improve stability,etc.,and become the primary choice for future high-performance perovskite photoelectric devices.The following section discusses the Bi3+doped perovskite system.The special electronic structure and non-toxic chemical properties of Bi3+improve the stability of perovskites and regulate the photoelectric properties,resulting in the preparation of high-performance solar cells.Finally,based on the current research status of halide perovskites solar cells,we foresee that the bis-muth ion doping strategy and ternary mixed cation perovskites can be combined in the future device optimization processes.Additionally,several potential research directions for achieving high-performance metal halide chalcogenide solar cells are highlighted.
