摘要:

有机-无机钙钛矿材料因为具有光谱吸收范围宽、缺陷密度低、载流子复合率低等非常优良的光电性能吸引了广泛关注, 掀起了钙钛矿材料研究热潮。近年来杂化钙钛矿型太阳能电池发展迅速, 光电转化效率目前已达到22.1%, 展现出极大的应用潜力。与多晶薄膜相比, 单晶具有极低的缺陷密度和极少的界面缺陷。多个课题组成功培养出大尺寸钙钛矿单晶, 发现钙钛矿单晶材料具有比其他薄膜多晶材料更好的光响应特性, 是设计制备光伏器件的理想材料。在各类钙钛矿材料中, CH3NH3PbI3是研究和应用最广泛的一类钙钛矿材料。本文主要针对近年来CH3NH3PbI3单晶材料的研究制备进行综述, 介绍了CH3NH3PbI3单晶材料的结构及性能, 重点总结了CH3NH3PbI3单晶材料生长制备方法和应用, 并对其发展趋势进行了展望。

Abstract:

Organic-inorganic hybrid halide perovskites have attracted a huge amount of research interest and arised new research upsurge due to its broad absorption range, low trap density, low carrier recombination, and other excellent optoelectronic properties. Perovskite solar cells have shown great potential for application with maximum power conversion efficiencies evolving from 3.8% to 22.1% in just a few years. Single crystal has extremely low defect density and minimal interface defect than polycrystalline materials. Several research groups successfully cultivated large-sized perovskite single crystals, finding that perovskite single crystal is an ideal material for design and fabrication of photovoltaic devices for better light-response than polycrystalline and thin-film materials. Among all kinds of perovskite materials, CH3NH3PbI3 is one of the most widely studied and applied perovskite materials. This paper reviews the study of CH3NH3PbI3 single crystal recently, introducing its structure and superior characteristics. Particularly, growth methods and applications of perovskite single crystals are highlighted. Finally, the development trend of perovskite single crystals is prospected.
