Perovskite solar cells represent a promising photovoltaic technology, which achieves record power conversion efficiencies over 24%. However, a problem on the commercial processing is the unavoidable efficiency loss during the scalable fabrication of perovskite solar module. The efficient and reliable fabrications of high‐quality large‐area perovskite films guarantee commercialized up‐scaling of perovskite solar cells with high efficiency. Herein, a simple dynamic antisolvent quenching (DAS) process is presented to understand large‐area uniform perovskite films to obtain an efficient perovskite solar module. This method provides a facile and universal approach to fabricate cracks‐free and uniform large‐area mixed‐cation perovskite films. A champion module device (10 × 10 cm²) with efficiency of 17.82% (another module with certified efficiency of 17.4%) is obtained using DAS process.

用于10×10 cm2钙钛矿太阳能电池组件旋涂的动态抗溶剂工程，接近18％

钙钛矿太阳能电池代表了一种有前途的光伏技术，可实现创纪录的功率转换效率超过24％。然而，商业加工中的问题是在钙钛矿型太阳能模块的可扩展制造期间不可避免的效率损失。高质量，大面积钙钛矿薄膜的高效可靠制造可确保钙钛矿太阳能电池的商业规模化升级。本文中，提出了一种简单的动态抗溶剂淬火（DAS）工艺，以了解大面积均匀的钙钛矿薄膜，从而获得有效的钙钛矿太阳能电池组件。这种方法为制造无裂纹且均匀的大面积混合阳离子钙钛矿薄膜提供了一种简便而通用的方法。冠军模块设备（10×10 cm ²）的效率为17.82％（使用DAS工艺获得另一个模块的认证效率为17.4％）。
