Multi-walled carbon nanotube/poly(3-hexylthiophene) (CNT/P3HT) and CNT-graft-poly(3-dodecylthiophene) (PDDT)/P3HT nanohybrids were applied in active layers to study the effects of these nanostructures on the polymer solar cell (PSC) performance. The charge-carrier dynamics and photophysics were studied in the binary and ternary systems based on P3HT, pre-developed nanostructures and/or phenyl-C71-butyric acid methyl ester (PC71BM) through the electrochemical impedance spectroscopy and morphological analyses. The weaker bimolecular recombination in the photoactive layer, consisting of CNT-graft-PDDT/P3HT nanostructures, was confirmed by short-circuit current (J_sc) and open-circuit voltage (V_oc) measurements as a function of light intensity. PSC composed of P3HT:PC71BM:CNT-graft-PDDT/P3HT PSC exhibited the highest PCE of 4.18% with significantly increased J_sc and V_oc.

将多壁碳纳米管/聚（3-己基噻吩）（CNT / P3HT）和CNT-接枝-聚（3-十二烷基噻吩）（PDDT）/ P3HT纳米杂化物应用于活性层，以研究这些纳米结构对聚合物太阳能的影响电池（PSC）性能。通过电化学阻抗谱和形态分析，在基于P3HT，预开发的纳米结构和/或苯基-C71-丁酸甲酯（PC71BM）的二元和三元系统中研究了载流子动力学和光物理。由短路电流（J _sc）和开路电压（V _oc）证实，由CNT-接枝-PDDT / P3HT纳米结构组成的光敏层中较弱的双分子复合。）测量值与光强度的关系。由P3HT：PC71BM：CNT-graft-PDDT / P3HT组成的PSC的PCE最高，为4.18％，J _sc和V _oc显着增加。
