Abstract: The Optoelectronic properties of organic-inorganic hybrid devices consisting of Ag/VOPc/n-Si/Ag structure have been investigated through analyzing the current-voltage characteristics. We have also studied the effect of illumination on the open circuit voltage, capacitance and reverse resistance with consideration of VOPc film thickness. The dark I-V characteristics display rectification behaviour of such hybrid structures and a very high photo-capacitive response under illumination of 200 lx is observed. Furthermore due to the generation of photo induced charges, under illumination, the decrease in reverse bias resistance to one third of its value is observed.

Abstract: The structural and surface properties of thin, metal oxides films can be tailored by including various additives in the precursors’ systm. The paper presents a comparative approach concerning the properties of WO3 thin layers obtained via spray pyrolysis deposition (SPD) using hydrophilic and hydrophobic polymers as additives. The influence of the thin films composition and morphology is reported, considering their applications of photocatalyst in the advanced treatment of waters resulted in the dye finishing industry, containing methylen blue and methyl orange.
