实验在聚（3-己基噻吩）（P3 HT）和[6，6]-苯基-C61-丁酸甲酯（PC 61 BM）共混物中掺杂低能带隙聚合物材料（PDTBDT-DTNT）作为互补电子给体，以提高有机太阳能电池（OSC）的功率转换效率（PCE）。通过掺杂10 wt% PDTBDT-DTNT，OSC的PCE从3.19%增加到3.75%，这比基于P3 HT：PC61 BM的二元共混物的OSC（宿主细胞）的PCE高17.55%。与宿主细胞相比，短路电流密度（Jsc）增加至10.11 mA·cm− 2。虽然PCE的改善可以部分归因于通过掺杂适当的PDTBDT-DTNT来获得更多的光子以用于2个供体的互补吸收，但是由于级联能级的矩阵而促进电荷分离和传输以及抑制电荷复合也是重要的。活性层薄膜的良好形貌有利于三元器件性能的优化。
Doping a low‐bandgap polymer material (PDTBDT‐DTNT) as a complementary electron donor in poly(3‐hexylthiophene) (P3HT) and [6,6]‐phenyl‐C61‐butyricacid methyl ester (PC61BM) blend is experimented to improve the power conversion efficiency (PCE) of organic solar cells (OSCs). The PCE of OSCs was increased from 3.19% to 3.75% by doping 10 wt% PDTBDT‐DTNT, which was 17.55% higher than that of the OSCs based on binary blend of P3HT:PC61BM (host cells). The short‐circuit current density (Jsc) was increased to 10.11 mA·cm−2compared with the host cells. Although the PCE improvement could partly be attributed to more photon harvest for complementary absorption of 2 donors by doping appropriate PDTBDT‐DTNT, the promotion of charge separation and transport as well as the suppression of charge recombination due to a matrix of cascade energy levels is also important. And the better morphology of the active layer films is beneficial to the optimized performance of ternary devices.
