Abstract

For the new working electrode materials of dye-sensitized solar cell (DSC), TiO₂/SiO₂ nanocomposite thin films were prepared by cathodic electrodeposition at room temperature. The thin film and DSC made of TiO₂/SiO₂ nanocomposite were characterized with photocurrent density, X-ray diffraction (XRD), field emission - scanning electron microscopy (FE-SEM) and photovoltaic performance test. The addition of appropriate amount of SiO₂ in the electrodeposition was essential and gave rise to achieve the superior crystallinity, photocurrent density and photovoltaic performance of the resulting TiO₂/SiO₂ electrode, which was significantly superior to a bare TiO₂ electrode. In the optimized TiO₂/SiO₂ electrode, SiO₂ was found to act as an energy barrier at the TiO₂/electrolyte interface, resulting in the significant enhancement of the photocurrent density on the film and the photovoltaic performance on the corresponding DSC.
