摘要

在实验室中，大多数钙钛矿薄膜都是通过自旋镀膜和抗溶剂工程来实现的。工业更喜欢卷对卷兼容技术，如槽模或刀片涂层，其中抗溶剂的应用一直被证明是有问题的。我们展示了一种新颖的方法，即用一张纸将钙钛矿薄膜沉积在空气中。与使用干燥的纸张相比，将用作涂抹剂的纸张浸泡在绿色抗溶剂中可以使太阳能电池的效率提高82%。最后，提出了该方法的自动化版本，以供将来实现。

Method for fabricating flexible solar cell perovskite semiconductors via a sheet of paper applicator soaked in anti-solvent

Most perovskite films in laboratories are deposited by spin coating and antisolvent engineering to achieve high efficiency. Industry prefers roll-to-roll compatible techniques such as slot-die or blade coating, where the application of anti-solvent has always proven to be problematic. We show a novel method that uses a sheet of paper to deposit the perovskite films in air. Soaking the paper used as an applicator in a green anti-solvent improved the efficiency of the solar cell by 82% compared to the same when using a sheet of dry paper. Finally, an automated version of the method is proposed for future implementation.
