空气稳定自由基 TTM-1Cz 作添加剂，D18:L8-BO 有机太阳能电池效率达 20.63%
Air‐Stable Radical Additives Modulate Spin‐Dependent Recombination in High‐Efficiency Organic Solar Cells
AI 导读
研究者在 D18:L8-BO 非富勒烯有机太阳能电池中引入空气稳定的有机自由基 TTM-1Cz 作添加剂，冠军能量转换效率达 20.63%，认证效率 20.45%。
推荐理由
原文用瞬态吸收与磁光电流区分了自由基添加剂的堆积效应与自旋调控作用，并给出 20.63% 的器件效率。
创新点
用空气稳定自由基的双重态引入自旋相关复合调控，并通过闭壳类似物对照把分子堆积效应与自由基特有的自旋效应区分开。
