We devised to fabricate ionic liquid-aided perovskite solar cells (PSCs) under atmospheric conditions with controlled 40% humidity using the bar coating method with the application to the future roll-to-roll method. The long-term moisture stability of IL-aided device (non-encapsulated) remain above 90% of their initial output after 1000 h storage at ambient with a relative humidity range of 40-50%.
