The growth of high-quality single-crystal (SC) perovskite films is a great strategy for the fabrication of defect-free perovskite solar cells (PSCs) with photovoltaic parameters close to the theoretical limit, which resulted in high efficiency and superior stability of the device. Plenty of growth methods for perovskite SCs are available to achieve a maximum power conversion efficiency (PCE) surpassing 21% for SC-based PSCs. However, there is still a lot of room to further push the efficiency by considering new crystal growth techniques, interface engineering, passivation approaches, and additive engineering. In this review, we summarize the recent progress in the growth of SC-based perovskite films for the fabrication of high-efficiency and stable PSCs. We describe the impact of SC growth of perovskite films and their quality on the device performance and stability, compared with the commonly used polycrystalline perovskite films. In the last section, the challenges and potential of SCs in PSCs are also covered for future development.
高质量单晶（SC）钙钛矿薄膜的生长是制造具有接近理论极限光伏参数的无缺陷钙钛矿太阳能电池（PSC）的重要策略，这使得器件具有高效率和卓越的稳定性。有大量用于钙钛矿SCs的生长方法可实现基于SC的PSC的最大功率转换效率（PCE）超过21%。然而，通过考虑新的晶体生长技术、界面工程、钝化方法和添加剂工程，仍有很大的提升效率的空间。在本综述中，我们总结了用于制造高效稳定PSC的基于SC的钙钛矿薄膜生长的最新进展。我们描述了钙钛矿薄膜的SC生长及其质量对器件性能和稳定性的影响，并与常用的多晶钙钛矿薄膜进行了比较。在最后一部分，还讨论了SCs在PSC中的挑战和潜力，以供未来发展参考。
