Abstract

A new polymer electrolyte Polyvinyl alcohol (PVA) doped with ammonium iodide (NH4I) have been developed, characterized and applied in Dye sensitized solar cell (DSSC). Polymer electrolyte shows enhancement in electrical conductivity by salt doping and then decrease after a certain composition. Infrared spectroscopy (IR) as well as x ray diffraction (XRD) affirmed composite nature of the polymer electrolyte. The polymer morphology has been studied using optical microscopy. Based on maximum conducting sample we have developed a DSSC which shows short circuit current density of 0.46 mA/cm2, open circuit voltage of 0.65 volt with overall conversion efficiency of 0.29 % at 1 sun condition..
