Abstract	This work presents a photo electrochemical cell based on zinc oxide (ZnO) nanoparticles and poly(acrylic) acid (PAA) doped with sodium iodide (NaI) and iodine (I$_{2}$) polymer gel electrolyte. The ZnO powders were synthesized by sol–gel storage and sol–gel centrifugation. The ZnO powder synthesized via sol–gel centrifugation showed the optimal structural properties, with largest crystallite sizes of 58 nm, average particles size between 20 and 80 nm and indirect band gap energy of 3.20 eV. The highest conductivity [(8.0 ± 0.1) × 10$^{−2}$ S cm$^{−1}$] was obtained for PAA + 0.8 M NaI + 0.02 M I$_{2}$. This sample achieved the lowest activation energy (0.029 eV) and electrochemical stability at 1.6 V. The ZnO powder synthesized via sol–gel centrifugation and PAA + 0.8 M NaI + 0.02 M I$_{2}$ was fabricated as a Cu–ZnO/PAA + 0.8 M NaI + 0.02 M I$_{2}$/C-ITO photo electrochemical cell.
