Abstract

Perovskite solar cells have achieved a high efficiency and exhibited great potential for commercialization. Blade- and slot-die-coating techniques are regarded as the most competitive approaches for the future industrialization due to their capability for large-area fabrication. In contrast to the simple spin-coating method employed in lab-scale fabrication, the blade- and slot-die-coating techniques involve complex fluid dynamics and film growth processes, thereby leading to inferior film quality and device performance. In this review, we comprehensively analyze the influence of fluid mechanisms involved in all the blade-coating process and summarize the key points for preparing large-scale and uniform perovskite films. Subsequently, we highlight the influence of different solvent extraction techniques on the nucleation and crystallization processes of perovskite films. Moreover, a comprehensive assessment is performed to present the current states and challenges faced by both single-junction wide- and narrow-bandgap solar cells as well as all-perovskite tandem solar cells. Finally, we present a discussion aimed at advancing the development of large-area perovskite solar cells.

用于串联装置的叶片涂覆钙钛矿：液体机制，薄膜形成和性能

钙钛矿太阳能电池已经取得了很高的效率，并显示出巨大的商业化潜力。刀片和槽模涂层技术被认为是未来工业化中最具竞争力的方法，因为它们具有大面积制造的能力。与实验室规模制造中采用的简单旋转镀膜方法相比，刀片和槽模镀膜技术涉及复杂的流体动力学和薄膜生长过程，因此导致薄膜质量和器件性能较差。本文综合分析了流体机制对叶片涂膜过程的影响，总结了制备大规模均匀钙钛矿膜的关键。随后，我们重点介绍了不同溶剂萃取技术对钙钛矿薄膜成核和结晶过程的影响。此外，对单结宽窄带隙太阳能电池以及全钙钛矿串联太阳能电池的现状和面临的挑战进行了全面的评估。最后，我们对推进大面积钙钛矿太阳能电池的发展进行了讨论。
