Enriched In2O3/WO3 nanocomposites as photoanode for a dye-sensitized solar cell in photo powered energy system

Tungsten oxide nanoparticles (PWNPs) and indium/tungsten oxide nanocomposites (IWNCs) were synthesized by the facile hydrothermal method. Powder X-ray diffraction (XRD) results confirmed the formation of the orthorhombic and body-centered cubic crystalline structure of PWNPs and IWNCs. An increase in roughness of IWNCs than PWNPs was evident through atomic force microscopy (AFM), which in turn increases the electrical conductivity of IWNCs. Dye-sensitized solar cells (DSSCs) for PWNPs and IWNCs were investigated as electron-transport layers in planar DSSCs. The integration of indium in the tungsten oxide layer led to enhanced power conversion efficiency (PCE) of about 4.69% due to the electron transfer and reduced back-recombination.

Automated summary

Tungsten oxide nanoparticles and indium/tungsten oxide nanocomposites were successfully synthesized by the hydrothermal method. The results showed that the integration of indium in the tungsten oxide layer can enhance the power conversion efficiency of dye-sensitized solar cells due to electron transfer and reduced back-recombination.
