Abstract

We have used sol-gel spin-coating method to prepare nano-crystalline titanium dioxide (TiO₂) films. An assembly of indium-tin oxide(ITO)/nano-crystalline TiO₂/polyaniline/Al has been made in a sandwich structure. The junction thus obtained shows rectifying behavior. Their I-V characteristics indicate that a p-n junction at nano-crystalline TiO₂-polyaniline interface has been created .In our experiment, we change the ratio of titanium alkoxide and ethanol in process of preparing TiO₂ sol, when the ratio of titanium alkoxide and ethanol at 3:7, the largest open voltage(Voc) of 0.397 V and short current density(Jsc) of 65.9 muA/cm² are obtained under simulated solar radiation (50 mW/cm²).
