Polyethylene oxide (PEO) gel polymer electrolytes (GPEs) were prepared using tetrapropylammonium iodide (TPAI). The mass fraction (TPAI) in the electrolyte was varied to increase the productivity of the solar cell. It increased the ionic conductivity of the electrolyte at room temperature from 8.426 1mОhm∗sm and 373K temperature to 18.117 1mОhm∗sm. The increase in ionic conductivity with the addition of TPAI salts was associated with an increase in the diffusion coefficient, mobility, and density of charge carriers.
