摘要
A series of conducting polymer complexes of poly (3-decylthiophene) and titanium dioxide (PDT/TiO 2) in different proportions were synthesized. Scanning electron microscope (SEM) depicted the morphology of the samples, defining that TiO 2 was successfully coated by poly (3-decylthiophene) molecules. X-ray diffraction patterns (XRD) showed that the interplaner spacing of the composite samples was smaller than the pure TiO 2. X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR) showed that there was chemical interaction between PDT and nano-TiO 2 in the complexes. Cyclic voltammetry (CV) showed that the energy gap of the PDT/TiO 2 composite was lower to 0.86 eV, which was the smallest when the proportion was 2:1. Ultraviolet-visible spectra (UV-vis) showed that optical performance was far superior to both PDT and TiO 2. A solar cell was sensitized by PDT/TiO 2, and a solar-to-electric energy conversion efficiency of 0.185% was obtained with the system.
