The design, synthesis, and characterization of the first examples of furan-containing low band-gap polymers, PDPP2FT and PDPP3F, with substantial power conversion efficiencies in organic solar cells are reported. Inserting furan moieties in the backbone of the conjugated polymers enables the use of relatively small solubilizing side chains because of the significant contribution of the furan rings to overall polymer solubility in common organic solvents. Bulk heterojunction solar cells fabricated from furan-containing polymers and PC(71)BM as the acceptor showed power conversion efficiencies reaching 5.0%.
本文报道了首例含呋喃低带隙聚合物 PDPP2FT 和 PDPP3F 的设计、合成与特性，这类聚合物在有机太阳能电池中具有较高的能量转化效率。将呋喃基团引入到共轭聚合物的主链中，可以使用相对较小的可溶性侧链，因为呋喃环对聚合物在常见有机溶剂中的整体溶解性有很大的贡献。以含呋喃聚合物和 PC(71)BM 作为受体制备的体异质结太阳能电池的能量转化效率达到了 5.0%。
