The Cover Feature shows the efficient and stable CH₃NH₃PbI₃ (MAPbI₃) 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(CH₃)₃NH₃⁺] 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. More information can be found in the Full Paper by Liu et al. on page 2385 in Issue 11, 2019 (DOI: 10.1002/cssc.201900106).

封面人物：通过痕量掺杂大型阳离子在高湿度环境中制造高效稳定的钙钛矿太阳能电池（ChemSusChem 11/2019）

封面特征示出了有效且稳定的CH ₃ NH ₃碘化铅₃（MAPbI ₃）钙钛矿高湿度气氛下的太阳能电池制备。当前报道的高性能设备是在受控的惰性/干燥气氛中制造的，这增加了潜在大规模生产的制造成本。在这项工作中，选定的叔丁基铵[C（CH ₃）₃ NH ₃⁺有机阳离子可以覆盖钙钛矿膜表面并填充其晶界，以保护其免受水的破坏。该措施可在相对湿度为50％的条件下制备出19.3％的功率转换效率，并改善了器件的湿度和热稳定性。有关更多信息，请参见Liu等人的论文全文。就在第11期，2019页2385（：10.1002 / cssc.201900106 DOI）。
