Abstract
The TiO2 films were deposited on glass substrate at different thicknesses with different deposition frequencies (1, 2, 3 and 4 times) using spin coating technique and their structural properties were investigated. Subsequently, the nanocomposited aligned ZnO nanorods and TiO2 were formed by deposited the TiO2 on top of aligned ZnO Nanorod on ITO-coated glass at different thicknesses using the same method of TiO2 deposited on glass substrate. The nanocomposited aligned ZnO nanorod/TiO2 were coated with different thicknesses of 900 mu m, 1815 mu m, 2710 mu m, 3620 mu m and ZnO without TiO2. The dyesensitized solar cells were fabricated from the nanocomposited aligned ZnO nanorod/TiO2 with thickness of 900 mu m, 1815 mu m, 2710 mu m and 3620 mu m and ZnO without TiO2 and their photovoltaic properties of the DSSCs were investigated. From the solar simulator measurement the solar energy conversion efficiency (eta) of 2.543% under AM 1.5 was obtained for the ZnO nanorod/TiO2 photoanode-2710 mu m Dye-Sensitized solar cell.
