摘要

金属卤化物钙钛矿太阳能电池已经能够实现25.7%的认证光电转化效率，接近于晶硅太阳能电池26.7%的最高认证效率。众所周知，,ABX,3,钙钛矿材料的晶体结构组分工程在实现高效和稳定的器件方面发挥着关键作用，尤其是近几年受到研究人员广泛关注的,X,位卤素阴离子组分工程。最近，研究人员在引入赝卤素阴离子作为钙钛矿晶体的掺杂组分、前驱体添加剂、薄膜后处理材料、电荷传输材料、界面钝化剂以及改性剂等方面开展了多项研究工作，结果证明赝卤素离子修饰是提高器件效率和稳定性的重要策略。本综述详细对比和总结了目前可用于钙钛矿太阳能电池的多种类型的赝卤素离子，并对其影响钙钛矿晶体薄膜形貌、光电特性、载流子迁移特性和器件光伏特性及稳定性等方面的深入机理和作用本质进行了深入总结。同时，本文还对目前尚未被探索开发的赝卤素离子进行了展望和分析，以期在未来研究中能有效促进钙钛矿太阳能电池光伏特性的提升。

Abstract

Metal halide perovskite solar cells have been able to achieve certified photovoltaic conversion efficiencies of 25.7%， approaching the maximum certified efficiency of 26.7% for crystalline silicon solar cells. It is well known that the component engineering of the crystal structure of ,ABX,3, perovskite materials plays a key role in achieving efficient and stable devices， especially the component engineering of the ,X,-site halide anion， which has received much attention from researchers in recent years. Recently， researchers have carried out several studies on the introduction of pseudo-halide anions as doping components， precursor additives， thin film post-treatment materials， charge transport materials， interfacial passivation， and modifiers for perovskite crystals， and the results demonstrate that pseudo-halide ion modification is an important strategy to improve device efficiency and stability. This review provides a detailed comparison and summary of the various types of pseudo-halide ions currently available for use in perovskite solar cells and provides an in-depth summary of the mechanisms and nature of their effects on perovskite crystal film morphology， photovoltaic properties， carrier migration properties， and device photovoltaic characteristics and stability. At the same time， this paper also provides an outlook and analysis of the currently unexplored pseudo-halide ions to effectively contribute to the enhancement of the photovoltaic properties of perovskite solar cells in future research.
