N2 - Quasi-solid-state electrolytes based on poly(vinylidene fluoride-co-hexafluoropropylene) (PVdf-HFP), propylene carbonate (PC), 1,2-dimethoxyethane (DME) and different concentrations of 1-methyl-3-propylimidazolium iodide (MPII) salt were prepared. The highest room temperature conductivity of 4.6 x 10-3 S cm-1 was achieved with 1.0M MPII. The effect of MPII on the conductivity was discussed on the basis of number free ions. The number of free ions were estimated by impedance spectroscopy method. DSSC at 1.0M MPII shows the conversion efficiency, η of 3.70% with short-circuit current density, Jsc of 8.65 mA cm-2, open circuit voltage, Voc of 641 mV and a fill factor, FF of 66%.
