Abstract
Tungsten oxide nanoparticles (PW NPs) and silver-doped tungsten oxide nanocomposites (SW NCs) were synthesized via hydrothermal method. Structural, optical, morphological, and electrical properties of the synthesized samples were characterized by X-ray powder diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDAX), and UV–visible spectroscopy. XRD results confirmed the formation of Ag2WO4 NCs with an average crystallite size ranging from 38 to 9 nm. SEM analysis revealed the formation of nanoclusters. Further SW4NCs shows highest rate constant (0.108 min−1) for methyl blue (MB) dye degradation. Variation in the electrical conductivity and activation energy was studied by DC conductivity studies. Dye-sensitized solar cells (DSSCs) were fabricated using PW and SW NCs films as photoanodes simultaneously, and the photoconversion efficiency (PCE) was found to increase.
