TiO2 Added PMMA : PVDF-HFP : NaClO4 Nanocomposite Solid Polymer Electrolyte and Its Application in Dye Sensitized Solar Cell

In the present research work, films of pure PMMA, pure PVDF-HFP, PMMA : PVDF-HFP : NaClO 4 polymer blend electrolyte, and different concentrations of TiO 2 nanoparticles doped PMMA : PVDF-HFP : NaClO 4 polymer electrolytes have been prepared with the help of solution casting technique. The research work attempted to fabricate dye sensitized Solar (DSS) cell using best TiO 2 nanoparticles doped thin film. Properties like structural, morphological, optical and conductivity of all the prepared thin films have been investigated through different characterization techniques such as XRD, SEM, FTIR, and AC conductivity respectively. From the results of XRD and SEM of these films, established dominant amorphous nature at 12 wt % of TiO 2 nanoparticles doped PMMA : PVDF-HFP : NaClO 4 thin film. The interaction/complexation of TiO 2 nanoparticles with polymers and salt is observed from IR spectra of vibrational bands. Ionic conductivity measurements of the films have been carried out using AC impedance spectro-scopy, and the optimum conductivity value was found at 1.12 × 10 –3 S/cm. Finally, dye sensitized Solar (DSS) cell has been constructed using the best polymer electrolyte i.e. 12 wt % of TiO 2 nanocomposition PMMA : PVDF-HFP : NaClO 4 , further fill factor and efficiency are calculated and reported as 0.853 and 8.29% respectively. The features of the developed DSS cell have been shown to be stable and exhibit remarkable potential in solar cells.
