Metal halide perovskite have shown great potential for applications in photovoltaics, light-emitting diodes and photon detectors, mainly owing to their superb optoelectronic properties, low-cost raw materials and facile fabrication process. Although, polycrystalline perovskite thin-films have been actively investigated for preparing various optoelectronic devices, the presence of detrimental defects at grain boundaries, serious ion migration and limited stability unfortunately hinder their device performance and practical application. As a contrast, perovskite single crystals (SCs) exhibit no grain boundaries, much lower trap density and much improved stability, hence providing a more attractive choice for not only optoelectronic device applications but also fundamental research. In this review, recent progress in the growth methods of perovskite SCs is summarized, followed by giving a detailed introduction of the intrinsic properties of perovskite SCs including optical properties, defects, charge carrier dynamics, ion migration and stability. On these base, the applications of perovskite SCs in various optoelectronic devices like solar cells, photodetectors, and radiation detectors are discussed, where the relationship between the composition, device architecture and device performance is highlighted. Finally, a tentative discussion on the current challenges and future opportunities in the development of perovskite SCs and optoelectronic devices is presented.

钙钛矿单晶的合成、本征性质及光电应用研究进展

金属卤化物钙钛矿在光伏、发光二极管和光子探测器方面显示出巨大的应用潜力，这主要是由于其卓越的光电性能、低成本的原材料和简便的制造工艺。尽管多晶钙钛矿薄膜已被积极研究用于制备各种光电器件，但不幸的是，晶界存在有害缺陷、严重的离子迁移和有限的稳定性阻碍了它们的器件性能和实际应用。相比之下，钙钛矿单晶 (SC) 没有晶界，陷阱密度低得多，稳定性也大大提高，因此不仅为光电器件应用而且为基础研究提供了更具吸引力的选择。在这篇评论中，总结了钙钛矿SCs生长方法的最新进展，然后详细介绍了钙钛矿SCs的固有性质，包括光学性质、缺陷、电荷载流子动力学、离子迁移和稳定性。在此基础上，讨论了钙钛矿 SC 在太阳能电池、光电探测器和辐射探测器等各种光电器件中的应用，重点介绍了组成、器件架构和器件性能之间的关系。最后，对钙钛矿 SC 和光电器件发展中的当前挑战和未来机遇进行了初步讨论。离子迁移和稳定性。在此基础上，讨论了钙钛矿 SC 在太阳能电池、光电探测器和辐射探测器等各种光电器件中的应用，重点介绍了组成、器件架构和器件性能之间的关系。最后，对钙钛矿 SC 和光电器件发展中的当前挑战和未来机遇进行了初步讨论。离子迁移和稳定性。在此基础上，讨论了钙钛矿 SC 在太阳能电池、光电探测器和辐射探测器等各种光电器件中的应用，重点介绍了组成、器件架构和器件性能之间的关系。最后，对钙钛矿 SC 和光电器件发展中的当前挑战和未来机遇进行了初步讨论。
