N2 - A duel-source co-evaporation technique is developed to fabricate Cs-substituted MA-{mathbf {1-x}} \mathbf {Cs} -{mathbf {x}}PbI-{mathbf {3}} perovskite film with superior large area uniformity, solar cell efficiency and stability. Upon optimization of all layers and interfaces, our current status for the rigid thin film cell efficiency is over 21.5% and that for the flexible device over 18.3%, both are among the highest for their respective categories. More importantly, the devices are found showing very good stability over long term exposure in ambient with very low degradation. After a representative cell was exposed in ambient lab condition for a year, its final cell efficiency is as high as over 95% of its initial efficiency with its degradation accounts for only smaller than 5%. Further analysis on the stability of the perovskite solar cells will be discussed.
