非富勒烯受体-铱配位聚合物 BTP-N-Ir 作三线态敏化剂，三元有机太阳能电池效率达 20.37%
Nonfullerene Acceptor−Iridium Coordination Polymer as a Triplet Sensitizer for Efficient Organic Photovoltaics
AI 导读
研究报道了一种非富勒烯受体-铱配位聚合物 BTP-N-Ir，作为三元有机太阳能电池的三线态敏化剂，器件最高效率达 20.37%。该聚合物敏化剂单-三线态能隙小，可生成寿命较长的三线态激子，激子转移至受体分子内激发（i-EX）态后解离为自由电荷贡献光电流。作者称这一以 i-EX 为中间态的三线态激子转移路径比此前体系更有效。
推荐理由
作者把非富勒烯受体与铱配位聚合，给出三线态激子经 i-EX 中间态转移的新路径，并记录 20.37% 的效率。
创新点
以非富勒烯受体与铱配位构建聚合物敏化剂，让三线态激子经受体 i-EX 中间态解离，形成区别于以往体系的三线态激子转移路径。
