The formation of bicontinuous carrier path between donor and acceptor pairs is an important factor for the enhancement of photovoltaic performance. Large interfaces can be generated in hybrid blends of organic and inorganic materials due to their intrinsic incompatibility, which leads to phase separation that could be used to improve the dissociation of photogenerated excitons into free charge carriers. In this study, is investigated the morphology diversity of the deposited organic materials on titania nanotubes. Used organic materials are copper phthalocyanine, sodium salt derivatives of copper phthlocyanine, and polythiophene. Titania nanotubes were prepared by the anodization of titanium foil. Nanostructures was developed with thermal vacuum evaporation, spin-coating, immersion, and electrochemical reactions. The factors affecting on the morphologies were analysed with the aid of SEM. |
