Abstract

In the current scenario, electrolyte plays a crucial role in the fabrication of Dye-Sensitized Solar Cells (DSSCs). To advance the performance of DSSCs, it is essential to explore electrolyte with polymers. Polyvinyl alcohol (PVA) is non toxic, bio compatible, bio degradable, thermally and chemically stable water-soluble polymer with excellent mechanical strength and transparency, which is anticipated to be an excellent candidate in DSSCs. An attempt was made on Polymer based electrolyte with nano filler thin films which are prepared using dip coating technique. The properties of the prepared films are characterized by various experimental techniques such as FTIR, UV-Vis and Electro Chemical Impedance spectroscopy. The Fourier Transform Infrared (FTIR) analysis reveals the complexation of the polymer nanocomposite network and the UV–visible spectral study shows the optical band gap. Besides, the impedance analysis indicates high ionic conductivity which is due to ionic mobility and segment motion of polymer network. The outcome of the studies reveals the interaction of electrolyte with polymer and nano filler for Dye -Sensitized Solar Cells.
