Abstract
The tin chloride mediated tin oxide (SnO2) nanoparticles were synthesized using sol–gel chemical method and further envisaged in dye-sensitized solar cells (DSSCs). Three steps; synthesis of nanoparticles, formation of paste using suitable surfactants and film development using doctor-blade method onto glass and indium-tinoxide substrates (annealed at 500 ℃ for 1 h) were preferred before making the SnO2 electrode for DSSCs application. Influence of ITO substrate on the structural elucidation, morphological evaluation, grain size and Raman shift properties of SnO2 nanoparticles was eliminated by forming a film onto ITO-free glass substrate. Enhanced light absorbance at 500 nm due to the N719 dye molecules adsorption compared to pristine SnO2 electrode revealed 1.7% solar-to-electrical conversion efficiency.
