Perovskite solar cells (PSCs) are gaining prominence in the photovoltaic industry due to their exceptional photoelectric performance and low manufacturing costs, achieving a significant power conversion efficiency of 26.4%, which closely rivals that of silicon solar cells. Despite substantial advancements, the effective area of high-efficiency PSCs is typically limited to about 0.1 cm in laboratory settings, with efficiency decreasing as the area increases. The limitation poses a major obstacle to commercialization, as large-area, high-quality perovskite films are crucial for commercial applications. This paper reviews current techniques for producing large-area perovskites, focusing on slot-die coating, a method that has attracted attention for its revolutionary potential in PSC manufacturing. Slot-die coating allows for precise control over film thickness and is compatible with roll-to-roll systems, making it suitable for large-scale applications. The paper systematically outlines the characteristics of slot-die coating, along with its advantages and disadvantages in commercial applications, suggests corresponding optimization strategies, and discusses future development directions to enhance the scalability and efficiency of PSCs, paving the way for broader commercial deployment.
钙钛矿太阳能电池（PSCs）因其卓越的光电性能和较低的制造成本，在光伏产业中日益受到关注，其功率转换效率高达26.4%，已可与硅太阳能电池相媲美。尽管取得了重大进展，但在实验室环境中，高效PSCs的有效面积通常限制在约0.1平方厘米，随着面积增加效率会降低。这一限制成为商业化的主要障碍，因为大面积、高质量的钙钛矿薄膜对于商业应用至关重要。本文综述了当前生产大面积钙钛矿的技术，重点介绍了狭缝式涂布法，该方法因其在PSC制造方面的变革潜力而备受关注。狭缝式涂布法可精确控制薄膜厚度，并且与卷对卷系统兼容，适用于大规模应用。本文系统地概述了狭缝式涂布法的特点，以及其在商业应用中的优缺点，提出了相应的优化策略，并讨论了未来的发展方向，以提高PSCs的可扩展性和效率，为更广泛的商业应用铺平道路。
