The Cover Feature shows the efficient and stable CH 3 NH 3 PbI 3 (MAPbI 3 ) perovskite solar cell prepared under high humidity atmosphere. The current reported high‐performance devices are fabricated in a controlled inert/dry atmosphere, which increases the manufacturing costs for the potential large‐scale production. In this work, the selected tert‐butylammonium [C(CH 3 ) 3 NH 3 + ] organic cations could cover the surface and fill the grain boundaries of the perovskite film to protect it from damage by water. This measure delivers a power conversion efficiency of 19.3 %, prepared under 50 % relative humidity, as well as improved humidity and thermal stability for the devices.
