Dye-sensitized solar cells (DSSCs) face limitations in achieving high efficiency due to the electron recombination phenomenon at the conductive oxide-electrolyte interface. In this study, to enhance the efficiency of DSSCs, doping TiO2 nanoparticles with WO3 nanostructures and silver was employed. The results revealed that utilizing this combination in the fabrication of the photoanode reduces electron recombination and improves the power conversion efficiency of the solar cells. Morphological analysis of the synthesized nanoparticles was carried out using scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). The findings of this study showed that the photoanode based on the Ag-TiO2-WO3 ternary nanostructure exhibited better performance compared to photoanodes made of pure TiO2, WO₃, and TiO2-WO3. Specifically, the cell with the Ag-TiO2-WO3 photoanode achieved a short-circuit current density (Jsc) of 13.63 mA/cm² and a power conversion efficiency of 6.87%. In contrast, cells made with photoanodes of pure TiO2, WO₃, and TiO2-WO3 demonstrated power conversion efficiencies of 3.171%, 0.93%, and 5.631%, respectively.
