<p>Photoactive (IOI) inorganic/organic interface assemblies were prepared using an occlusion electrodeposition method. Poly-2,2′:5′,2′′-Terthiophene (PTTh) were the organic thin films that occluded each of CdS, TiO<sub>2</sub>, and Zn-doped WO<sub>3</sub> nanoparticles.<strong> </strong>The energy band gap structures were investigated using spectroscopic and electrochemical techniques.<strong> </strong>The obtained assemblies were investigated in aqueous solutions under both dark and

Oxygen played an important role in minimizing electron/hole recombination as was evident by observed very low photocurrent when oxygen was removed by nitrogen purge. Results show that PTTh/CdS gave the greatest photocurrent, followed by PTTh/Zn-WO<sub>3</sub> and PTTh/TiO<sub>2</sub>.</p>
