Polymer electrolytes were prepared by doping PEO:KI/I 2 with an ionic liquid (IL) 1‐ethyl 3‐methylimidazolium thiocyanate (EMImSCN). FTIR confirmed composite nature while X‐ray diffraction (XRD) measurement affirmed the reduction in crystallinity, when IL was added. The ionic conductivity was improved by the addition of IL. The photoelectrochemical effect of the IL–doping in the terms of the current density J sc and efficiency of a dye sensitized solar cells (DSSC) has also been discussed.
