Abstract

ABSTRACT: Poly(1-vinylpyrrolidone- co -vinyl acetate)-based quasi-solid polymer electrolytes doped with potassium iodide are prepared. The highest room temperature ionic conductivity of 1.72 mS cm −1 is obtained. The dielectric studies are performed to understand the ion conduction mechanism. Fourier transform infrared study has been performed to understand complexation of the poly(1-vinylpyrrolidone- co -vinyl acetate)-based quasi-solid polymer electrolytes. The best power energy conversion efficiency (η) obtained is 2.94% with short circuit current density ( J sc ) of 8.05 mA cm −2, open circuit voltage ( V oc ) of 0.58 V, and fill factor of 63% under standard light intensity of 100 mW cm −2 irradiation.
