抄録

Porous and crystalline TiO2 films were prepared on individual metallic Ti plates by the micro-arc oxidation (MAO) method. A novel dye-sensitized solar cell (DSSC) was fabricated ; a TiO2 film prepared on a metallic Ti plate was used as the cathode, and an indium tin oxide (ITO) glass plate was employed as the anode. This cell possessed characteristics of DSSC. The TiO2 films were prepared in NH4H2PO4, (NH4)2HPO4, and (NH4)3PO4 electrolyte solutions by MAO. Their crystal structures were characterized by an X-ray diffractometer (XRD), surface morphologies were observed by a scanning electron microscope (SEM), and thicknesses were measured using an eddy-current-type film thickness meter. The results indicated that all films comprised a single-phase of anatase TiO2, exhibited porous surfaces, and had thicknesses in the range of about 2∼5 μm. The effects of the electrolyte solutions on the TiO2 films prepared in them were evaluated. It was found that the TiO2 film prepared in (NH4)2HPO4 exhibited the smallest pore size, namely, 0.5 μm and the smoothest surface morphology. The maximum starting power of a DSSC fabricated in this study was 394.7 mV.
