This study investigates the optical and morphological characteristics of ZnO, Al-doped ZnO (ZA), and ZnO:Al-SiO2 (ZAS) nanorods prepared using a hydrothermal method. The incorporation of SiO2 aims to enhance light absorption and surface properties, with potential relevance to dye-sensitized solar cell (DSSC) photoanode materials. UV-Vis spectroscopy showed a slight decrease in band gap with Al doping, while the addition of SiO2 improved the overall absorbance. FESEM analysis revealed that the ZAS sample had a more compact and uniform morphology. These results suggest that the combined effects of Al doping and SiO2 compositing can enhance the structural and optical properties of ZnO nanorods, making them promising candidates for future application in DSSC devices. © Published under licence by IOP Publishing Ltd.
