Single-component iodonium initiators with strong oxidability and different electron delocalization properties were designed to replace lithium bis(trifluoromethanesulfonyl)imide and 4-tert-butylpyridine in doped 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD), which can oxidize Spiro-OMeTAD without air assistance. The devices based on this oxidizing Spiro-OMeTAD showed excellent efficiencies of 25.16 % (certified: 24.85 % for 0.062-cm²) and 20.71 % for a 15.03-cm² module as well as remarkable overall stability.

碘引发剂：为 Spiro-OMeTAD 的无空气氧化提供高效稳定的钙钛矿太阳能电池

设计了具有强氧化性和不同电子离域特性的单组份碘鎓引发剂来代替掺杂的2,2′,7,7′-四(N,N-二-p)中的双(三氟甲磺酰)亚胺锂和4-叔丁基吡啶。 -甲氧基苯胺)-9,9'-螺二芴 (Spiro-OMeTAD)，无需空气辅助即可氧化 Spiro-OMeTAD。基于这种氧化 Spiro-OMeTAD 的器件表现出 25.16% 的出色效率（经认证：0.062-cm ²模块为 24.85%），15.03-cm ²模块为 20.71%，以及出色的整体稳定性。
