有機-無機復合鈣鈦礦單晶材料的研究進展

Research Progress of Organic-Inorganic Composite Perovskite Single Crystal Materials

  • 摘要: 由於具有可調諧的光學帶隙, 較高的載流子遷移率, 高外量子效率, 較長的載流子壽命和載流子擴散長度等優點, 新型有機-無機復合鈣鈦礦材料在太陽能電池, 光電探測器, LED等光電領域展現出潛在的應用優勢。自2009年第一塊鈣鈦礦太陽能電池獲得了3.8%的光電轉換效率以來, 鈣鈦礦材料成為世界範圍內研究的熱點。根據近年來鈣鈦礦材料的發展歷程, 概述了鈣鈦礦單晶材料從含Pb到無Pb(包含Sn-基, Ge-基無鉛鈣鈦礦材料, 類鈣鈦礦材料以及雙鈣鈦礦材料)的發展歷程和主要應用領域。

     

    Abstract: 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.
