本文综述了近年来有机金属卤化物钙钛矿太阳能电池的研究进展。我们讨论了用于构建钙钛矿光活性层的不同化合物，以及该系统的光电特性。探讨了影响钙钛矿活性层形貌的因素，如材料组成、膜沉积方法、铸造溶剂和各种后处理。本文回顾了最近出现的制备高性能钙钛矿薄膜的不同策略，以创建具有大或小晶粒尺寸的多晶薄膜。总结了采用介超结构和平面结构构建的器件，并讨论了制造工艺对操作效率的影响。最后，概述了钙钛矿太阳能电池发展中的重要研究挑战（滞后、热湿不稳定性、机械柔韧性以及无铅材料的开发），并讨论了它们的潜在解决方案。
We review recent progress in the development of organometal halide perovskite solar cells. We discuss different compounds used to construct perovskite photoactive layers, as well as the optoelectronic properties of this system. The factors that affect the morphology of the perovskite active layer are explored, e.g. material composition, film deposition methods, casting solvent and various post-treatments. Different strategies are reviewed that have recently emerged to prepare high performing perovskite films, creating polycrystalline films having either large or small grain size. Devices that are constructed using meso-superstructured and planar architectures are summarized and the impact of the fabrication process on operational efficiency is discussed. Finally, important research challenges (hysteresis, thermal and moisture instability, mechanical flexibility, as well as the development of lead-free materials) in the development of perovskite solar cells are outlined and their potential solutions are discussed...
