Solution-coating processes are promising methods to form active layers with low-cost input in the industrial development of perovskite solar devices. Among available coating processes, of particular interest are those capable of producing uniform coatings with small defect distribution over large areas at high speeds, referred to as scalable methods. Slot-die coating is one of these methods. It involves the meniscus coating of liquids or solutions over a static or moving substrate. This review discusses recent advances in slot-die coating of active layers used in perovskite solar cells (PSCs) and modules (PSMs). Various strategies to control ink spreading over substrates, wet film drying, and post-coating crystallization of light-absorbing perovskite layer are outlined along with different approaches and materials used in post-deposition defects healing. Then, commonly used solvents for perovskite ink formulation are analyzed based on their specific rheology and potential effect on human health and equipment safety. Also, precursor materials, solvents, and strategies to obtain desirable properties and morphology in the slot-die coating of charge-transporting layers are discussed. Lastly, an analysis of the performance of slot-die coated perovskite solar mini-modules and future perspectives on this topic conclude this review.

用于可扩展制造钙钛矿太阳能电池和模块的狭缝模头涂层

在钙钛矿太阳能器件的工业开发中，溶液涂覆工艺是一种以低成本形成有源层的有前途的方法。在可用的涂层工艺中，特别令人感兴趣的是那些能够在大面积上高速生产具有小缺陷分布的均匀涂层的工艺，称为可扩展方法。狭缝模头涂布是这些方法之一。它涉及在静态或移动基材上进行液体或溶液的弯液面涂层。本综述讨论了钙钛矿太阳能电池（PSC）和模块（PSM）中使用的有源层槽模涂层的最新进展。概述了控制油墨在基材上铺展、湿膜干燥和光吸收钙钛矿层的涂覆后结晶的各种策略，以及用于沉积后缺陷修复的不同方法和材料。然后，根据其特定的流变性以及对人类健康和设备安全的潜在影响，对钙钛矿油墨配方中常用的溶剂进行了分析。此外，还讨论了前体材料、溶剂以及在电荷传输层的狭缝模头涂层中获得所需性能和形态的策略。最后，对槽模涂层钙钛矿太阳能微型模块的性能进行了分析，并对该主题的未来展望进行了总结。
