Abstract

• Zinc oxide nanorod with hexagonal structure was achieved by using chemical bath deposition method under atmospheric pressure by using zinc nitrate hexahydrate [Zn(NO3)2.6H2O] and hexamethylene-tetramine (C6H12N4) at constant temperature 93ºC and the deposition time of 2 hours, 4 hours and 6 hours. The prepared film was grown on the surface of zinc oxide seed layer. The surface morphologies and the structural characterization of zinc oxide (ZnO) nanorods were characterized by Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) technique. The XRD pattern of the sample revealed that ZnO nanorods have hexagonal crystallite structure. Photovoltaic parameters such as short circuit current density Jsc, open circuit voltage Voc, fill factor FF, and overall conversion efficiency η for the fabricated cells were determined under illumination. In the analysis of photoelectrochemical properties, ZnO DSSC showed more pronounce in their performance and it has the efficiency of 0.12%.
