摘要: In this study, zinc oxide (ZnO) nanorods were synthesized on indium-tin-oxide (ITO) glass substrates by a hydrothermal process using various molar concentrations of Zn(NO3)2•6H2O+C6H12N4. Subsequently, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and x-ray diffraction (XRD) were used to obtain the surface morphology, chemical composition, and crystallographic structure of the nanorods. These nanorods were then submerged in a dye solution and used as the working electrode for a dye-sensitized solar cell (DSSC). The I-V and optoelectronic characteristics of DSSCs using the nanorods prepared by various concentrations of Zn(NO3)2•6H2O+C6H12N4 as the electrodes were measured to obtain their fill factors and conversion efficiency. The experimental results revealed that the ZnO film prepared by 0.2M of this compound exhibits a uniform distribution of dense nanorods whose shape and microstructure are beneficial to dye adsorption and carrier transport. Therefore, the DSSC fabricated with the nanorods prepared by the 0.2M process has an improved short-circuit current, fill factor, and conversion efficiency.
