- Abstract
TiO nanostructures have been treated using different kind of surfactant to modify its optical absorption and morphology. TiO nanostructures were prepared via simple method on indium tin oxide (ITO) surface, namely, liquid-phase deposition technique (LPD) at 50°C. The TiO nanostructures film with a thickness of about 236 nm was annealed at 400°C for 1 h in the air to enhance the interconnectivity of the particles. The dense and compact TiO nanoparticle with different shape, particle size and surface morphology was used as a photovoltaic material in a photo-electrochemical cell of ITO/TiO/electrolyte/platinum. TiO nanostructure films were treated with three different kinds of surfactants: cetyltrimethylammonium bromide (CTAB), hexamethylenetetramine (HMT) and polyvinylpyrrolidone (PVP). It was found that the film treated with HMT performed best, with a J of 57.5 μA/cm. In conclusion, optical absorption, band gap and grain size of TiO nanostructure influenced the performance of the cell.
