Tungsten-doped TiO2 thin films were prepared by sol–gel method on fluorine-doped tin oxide-coated substrates as working electrodes of dye-sensitized solar cells. The influences different W doping (0, 2, 4, 6, and 8 at%) the microstructure, optical, photovoltaic properties W-TiO2 thin-film DSSCs studied measurement X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), Brunauer–Emmett–Teller (BET) analysis, electrochemical impedance (EIS). An optimal performance was observed with a 6 at% W-doped film, resulting in Voc 0.68 V, Jsc 20.2 mA/cm2, an FF 68.6%, efficiency (η) 9.42%. photoanode improved 75%. This is because film increases specific surface area transfer rate.
