摘要
As a new generation of solution-processable optoelectronic materials, organic-inorganic hybrid halide perovskites have attracted a great deal of interest due to their high and balanced carrier mobility, long carrier dif- fusion length and large light absorption coefficient. These materials have demonstrated wide applications in solar cell, light-emitting diode, laser, photodetector, catalysis and other fields. Comparing with their polycrystalline film counter- part, perovskite single crystals have low trap density and no grain boundaries and thus are anticipated to possess much better optoelectronic performances. Herein, we review the key progress in the development of organic-inorganic halide perovskite single crystals. Particularly, the crystal growth techniques and applications of these advanced materials are highlighted.
作为一种新型的光电材料,有机-无机杂化钙钛矿以其高光吸收系数、长扩散长度、高载流子迁移率等优点为人们所关注.这类材料在太阳电池、光电探测器、发光二极管、激光器、催化等诸多领域有极为优秀的表现.与多晶材料相比,单晶的低缺陷、无晶界等特点使其拥有更好的性能.本文从生长技术和应用两个方面综述了有机-无机杂化钙钛矿单晶的研究进展,并对该领域的未来发展进行了展望.
