High-molecular-weight conjugated polymer HD-PDFC-DTBT with N-(2-hexyldecyl)-3,6-difluorocarbazole as the donor unit, 5,6-bis(octyloxy)benzothiadiazole as the acceptor unit, and thiophene as the spacer is synthesized by Suzuki polycondensation. HD-PDFC-DTBT shows a large bandgap of 1.96 eV and a high hole mobility of 0.16 cm(2) V(-1) s(-1) . HD-PDFC-DTBT:PC71 BM-based inverted polymer solar cells (PSCs) give a power conversion efficiency (PCE) of 7.39% with a Voc of 0.93 V, a Jsc of 14.11 mA cm(-2) , and an FF of 0.56.
通过铃木缩聚反应合成了以N-(2-己基癸基)-3,6-二氟咔唑为给体单元、5,6-双(辛氧基)苯并噻二唑为受体单元、噻吩为间隔基的高分子量共轭聚合物HD-PDFC-DTBT。HD-PDFC-DTBT具有1.96 eV的大带隙和0.16 cm² V⁻¹ s⁻¹的高空穴迁移率。基于HD-PDFC-DTBT:PC71 BM的倒置聚合物太阳能电池（PSC）的功率转换效率（PCE）为7.39%，开路电压（Voc）为0.93 V，短路电流密度（Jsc）为14.11 mA cm⁻²，填充因子（FF）为0.56。
