摘要：This paper reports on the enhanced cell efficiency of structures and properties of regioregular poly(3- hexylthiophene) (P3HT)/multiwalled carbon nanotube (MWNT) hybrid materials. The prepared hybrid materials were characterized using ultraviolet–visible absorption spectroscopy, photoluminescence spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Different concentrations of these MWNTs were suspended in polymer solutions and spin-cast onto indium tin oxide (ITO) glass. Solar cells with a device structure of ITO/poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate)/P3HT:MWNTs/aluminum were then produced using evaporated aluminum as the back contact. The results showed that the ratio of P3HT to MWNTs considerably influenced the performance of the fabricated solar cells. The efficiency of the solar cells increased with the ratio of carbon nanotubes. Monochromatic incident photon-to-electron conversion efficiency analysis was performed and the results indicated that at the optimal P3HT/MWNTs ratio (=1/1), the solar cells demonstrated a high-quality conversion of 2.16% with a fill factor of 42.22%, an open circuit voltage of 0.56 V, and a short circuit current of 9.12 mA/cm2.
