Low ionic conductivity in gel polymer electrolytes with large cations is undoubtedly a critical issue. This research's main objective was to explore potassium iodide influences on the conductivity in gel polymer electrolytes. PVA-based gel polymer electrolytes (GPEs), including tetrapropyl ammonium iodide and potassium iodide have been prepared. The GPEs have been characterized by X-ray diffraction (XRD) and electrical impedance spectroscopy (EIS). The GPEs prepared haves been recognized as an amorphous region through the X-ray diffraction analysis. The GPE sample's conductivity (100 wt% of tetrapropyl ammonium iodide) of 6.24 x 10(-3) S cm(-1) was the lowest. The existence of potassium iodide in the GPE system improves the conductivity. The conductivity of 9.72 x 10(-3) S cm(-1) of GPE containing 30 wt% of tetrapropyl ammonium iodide and 70 wt% of potassium iodide was the highest derived from the EIS analysis. All prepared GPEs have the potential to be used for dye-sensitized solar cell applications. The dyesensitized solar cell efficiency has been improved by similar to 30% if potassium iodide exists in the GPE system.
