This work presents new bulk p-n hetero-junction where iodine doped TiO(2) (I-TiO(2)) acts as n and poly(3, 4-ethylenedioxythiophene): polystyrenesulphonate (pEDOT:PSS) as p-element. Heterogeneous films were obtained by means of potentiostatic polymerization of monomer on the metal electrode in presence of suspended I-TiO(2) particles in the electrolyte, (applied potentials in a range of 0.8-1.1 V versus Ag/AgCl/0.1M KCl). The procedure brings about hybrid films where I-TiO(2) particles are uniformly incorporated into the bulk polymer matrix. An incorporation of I-TiO(2) into the pEDOT: PSS matrix causes increase in the measured current under visible light illumination.
