报告摘要：

有机-无机复合钙钛矿材料ABX3具有特殊的光导、离子导电、电导和发光等性能，在太阳能电池、场效应晶体管、以及发光二极管等领域具有潜在的应用价值，是世界各国研究的热点，目前研究比较多的大都是含Pb的有机-无机复合钙钛矿材料，在太阳能电池方面光电转换效率已经突破25.2 %，同时考虑到Pb的毒性，寻找替代Pb的材料成为目前研究的焦点。

对于有机-无机复合钙钛矿材料研究，大都是基于多晶或无定形薄膜材料，不能准确的反映材料的本征性质以及可能存在的各向异性。高质量的晶体是研究材料物理本征性能的最佳载体，基于以上问题，我们研究组率先在国际上合成与生长了含Pb的和无Pb的有机-无机复合钙钛矿大尺寸的单晶，并且对其基本性能进行了表征，相关工作发表在Angew. Chem. Int. Ed., Chem. Mater., J. Mater. Chem. A, CrystEngComm等国际知名期刊上。
