Organic-inorganic perovskite solar cells (PSCs) are among the most attractive and efficient emerging thin film photovoltaic technologies. The perovskite films have been fabricated by lots of deposition methods, including one-step/two-step spin coating, thermal evaporation and vapor assisted processes. However, the laboratory-based fabrication methods are not well matched with large area manufacture for actual use. Spray coating deposition technique is being explored to prepare perovskite films to break the bottleneck plaguing large scale production. Herein, a comprehensive study is conducted in fabricating perovskite films by air-brush spraying method. The spraying process is classified into three stages, namely, 1) atomization process, 2) droplet flight and 3) film deposition. Each of them is discussed in detail from principles to parameters. Integrating the three aspects above, high quality perovskite films comparable to spin coated films are obtained. A best power conversion efficiency (PCE) of 16.68% is achieved for planar structure PSCs, which is prominent among the PSCs fabricated by spraying method. In addition, devices with spraying method show excellent optical and electrical properties. The principles we discuss here could be applied in the actual condition for mass production.

有机-无机钙钛矿太阳能电池（PSC）是最有吸引力和最有效的新兴薄膜光伏技术之一。钙钛矿薄膜是通过许多沉积方法制造的，包括一步/两步旋涂，热蒸发和蒸汽辅助工艺。但是，基于实验室的制造方法不能与实际使用的大面积制造很好地匹配。正在探索喷涂沉积技术来制备钙钛矿薄膜，以打破困扰大规模生产的瓶颈。在此，对通过气刷喷涂法制造钙钛矿薄膜进行了全面的研究。喷涂过程分为三个阶段，即1）雾化过程，2）液滴飞散和3）膜沉积。从原理到参数均详细讨论了它们中的每一个。综合上述三个方面，获得了可与旋涂膜相比的高质量钙钛矿膜。平面结构PSC的最佳功率转换效率（PCE）为16.68％，这在通过喷涂方法制造的PSC中尤为突出。此外，采用喷涂方法的设备还具有出色的光学和电学性能。我们在这里讨论的原理可以应用于大规模生产的实际条件。
