| Abstract: | Well-aligned ZnO nanorod arrays (ZNRAs) were grown on coated indium tin oxide coated glass substrates from aqueous solutions at low temperature. Morphologies, crystalline structure and optical transmission were investigated by a scanning electron microscope, X-ray diffraction and UV–Visible transmission spectra, respectively. The results showed that ZNRAs grew vertically from the substrates, having uniform thickness and length distribution, ZnO nanorods were wurtzite-structured (hexagonal) ZnO. The high optical transmission in the visible region was also achieved. Furthermore, a hybrid solar cell was be constructured using ZNRAs as inorganic layer, and a power conversion efficiency of 0.47 % was achieved. |
