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.

Abstract
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.| File | Dimensione | Formato | |
