Effect of anatase TiO2 overlayer on the photovoltaic properties of rutile phase nanostructured dye-sensitized solar cell

摘要

Titanium Dioxide (TiO2) optoelectronic devices and a potential material for the future solar cell applications. In this study, the combination of anatase-phased TiO2 layer and rutile-phased TiO2 nanorods and nanoflowers film will be studied. Anatase-phased TiO2 layer was deposited using Spray Pyrolysis Deposition method and rutile-phased TiO2 nanorods and nanoflowers film were prepared by hydrothermal method using steel made autoclave. Crystalline structures, morphology characteristics of combinated films were investigated by X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM) and power conversion efficiency.
