有机-无机复合钙钛矿单晶材料的研究进展

由于具有可调谐的光学带隙、较高的载流子迁移率、高外量子效率、较长的载流子寿命和载流子扩散长度等优点,新型有机-无机复合钙钛矿材料在太阳能电池、光电探测器、LED等光电领域展现出潜在的应用优势。自2009年第一块钙钛矿太阳能电池获得了3.8%的光电转换效率以来,钙钛矿材料成为世界范围内研究的热点。根据近年来钙钛矿材料的发展历程,概述了钙钛矿单晶材料从含Pb到无Pb(包含Sn-基、Ge-基无铅钙钛矿材料、类钙钛矿材料以及双钙钛矿材料)的发展历程和主要应用领域。

Research Progress of Organic-Inorganic Composite Perovskite Single Crystal Materials

New organic-inorganic hybrid perovskite materials exhibit potential applications in photoelectric fields (such as solar cells, photodetectors, LED and so on), due to their tunable optical bandgap, high carrier mobility, high external quantum efficiency, and long carrier lifetime as well as carrier diffusion length. Since the first perovskite quantum dot sensitized solar cells were prepared with the efficiency of 3.8% in 2009, perovskite materials have once again raised the research boom and widely been studied worldwide. Based on the development of perovskite materials in recent years, the single crystals of Pb-based perovskite materials and Pb-free perovskite materials, including Sn-based, Ge-based perovskite materials, perovskite-like materials and double perovskite materials and their application were reviewed.
