Solid polymer electrolytes (SPEs) were prepared using rice starch as the polymer, sodium iodide (Nal) as the salt and 1-hexyl-3-methylimidazolium iodide (HMII) as the ionic liquid (IL). The solution casting technique was used for preparation of the PEs. The ionic conductivity and temperature dependent properties of the PEs were measured and all the SPEs were found to follow the Arrhenius thermal activated model. Ionic conductivity increased as the percentage of ILs increased. The SPE containing 20% (wt) of HMII IL showed the highest ionic conductivity of 1.83 x 10(-3) S/cm. Spectral and structural characterization of the PEs were performed by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD), respectively. The results of thermogravimetric analysis (TGA) and differential scanning calorirnetry (DSC) indicate that the decomposition temperature (T-dc), glass transition temperatures (T-g) and melting points (T-m) shifted when complexation with HMII occurred. The PEs were used to fabricate dye -sensitized solar cells (DSSCs) and the DSSCs were analyzed under a 1-sun simulator. The SPE with the highest ionic conductivity displayed a short circuit current density (J(sc)) of 9.07 (mA cm(-2)), open circuit voltage (V-oc) of 0.58 (V), a fill factor (FF) of 0.65 and had the highest energy conversion efficiency of 3.42%.
