| 英文摘要 | Nanocrystalline TiO2 films were prepared on flexible Ti-metal sheets by electrophoretic deposition followed by chemical treatment with tetra-n-butyl titanate (TBT) and sintering at 450 degrees C. X-ray diffraction (XRD) analysis indicates that TBT treatment led to the formation of additional anatase TiO2, which plays an important role in improving the interconnection between TiO2 particles. as well as the adherence of the film to the substrate, and in modifying the surface properties of the nanocrystalline particles. The effect of TBT treatment on the electron transport in the nanocrystalline films was studied by intensity-modulated photocurrent spectroscopy (IMPS). An increase in the conversion efficiency was obtained for the dye-sensitized solar cells with TBT-treated nanocrystalline TiO2 films. The cell performance was further optimized by designing nanocrystalline TiO2 films with a double-layer structure composed of a light-scattering layer and a transparent layer. The light-scattering effect of the double-layer nanocrystalline films was evaluated by diffuse reflectance spectra. Employing the double-layer nanocrystalline films as the photoelectrodes resulted in a significant improvement in the incident photo-to-current conversion efficiency of the corresponding cells due to enhanced solar absorption by light scattering. A high conversion efficiency of 6.33% was measured under illumination with 100 mW cm(-2) (AM 1.5) simulated sunlight. (C) 2009 Elsevier Ltd. All rights reserved. |
