Abstract: Perovskite films have fostered significant progress in the field of optoelectronic devices, particularly in solar cells, due to their excellent optoelectronic properties and cost-effective fabrication process. As a promising technique for large-scale industrial production of perovskite films, the blade-coating method has attracted wide attention because of its low cost, large-area coating capability, and simplicity. However, during the blade-coating process, perovskite films often present challenges such as poor film uniformity, high defect density, and uneven crystallization, which greatly affect the efficiency and stability of the devices. In this review, we summarize the application of blade-coating methods to the fabrication of perovskite films, with a focus on analyzing key factors affecting film quality, including precursor solution formulations, solvent characteristics, evaporation rate, crystallization kinetics, and film thickness. In particular, we discuss the impact of environmental factors on the perovskite crystallization process during blade-coating and explore how optimizing the blade-coating process and precursor solution composition can improve film uniformity and device performance. Additionally, we discuss the main challenges and shortcomings in the blade-coating preparation of perovskite films, including defects during large-area fabrication, differences in solvent evaporation rates, and their effects on crystallization quality. Strategies for addressing these issues are proposed. Finally, the future prospects of the blade-coating method in large-scale production of perovskite films are outlined, emphasizing the importance of a deeper understanding of perovskite film crystallization mechanisms and the development of novel additives to enhance the performance of perovskite optoelectronic devices and accelerate their industrialization.
