A novel 2D benzodifuran (BDF)-based copolymer (PBDF-T1) is synthesized. Polymer solar cells fabricated with PBDF-T1 show high power conversion efficiency of 9.43% and fill factor of 77.4%, which is higher than the performance of its benzothiophene (BDT) counterpart (PBDT-T1). These results provide important progress for BDF-based copolymers and demonstrate that BDF-based copolymers can be competitive with the well-studied BDT counterparts via molecular structure design and device optimization.
一种新型二维苯并二呋喃（BDF）基共聚物（PBDF-T1）被合成。使用 PBDF-T1 制备的聚合物太阳能电池表现出 9.43%的高光能量转换效率和 77.4%的填充因子，这高于其苯并噻吩（BDT）对应物（PBDT-T1）的性能。这些结果为 BDF 基共聚物提供了重要进展，并表明通过分子结构设计和器件优化，BDF 基共聚物可以与经过充分研究的 BDT 对应物相竞争。
