Abstract
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 (Jsc) and open-circuit voltage (Voc) 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 Jsc and Voc.
