Study of Effect TiO2 Thin Film Morphological on Polyaniline/TiO2 Solar Cell Efficiency
AMER N. J AL-DAGHMAN
Abstract
In this work study preparation, structural, optical and electrical properties of polyaniline (PANi), nanocrystalline TiO2 and PANi: TiO2 nanocomposites. The TiO2 powder of particle size 50-60 nm was synthesized by sol-gel technique and the polyaniline was synthesized by chemical oxidative polymerization of aniline. The composite films were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) and UV-Vis spectroscopy and the results were compared with polyaniline films. The intensity of diffraction peaks for PANi: TiO2 composites are lower than for TiO2. The characteristic FTIR peaks of PANi were found shift to higher wave number in PANi: TiO2 composite. These observed effects have been attributed to interaction of TiO2 particles with PANi molecular chains.
