Transmission Electron Microscopy, X-ray Diffraction and Raman Scattering Studies of Nanophase TiO2

Dye-sentized solar cells differ from conventional semiconductor devices in that they separate the function of lught absorption from charge-carrier transport. In the present authors' review, the principal role of the TiO2 photoanode is emphasized by a detailed presentation of its characterization by different experimental methods, while the photoelectric responses of the cells, a work which is still in progress, are indicated in the references cited. In the present work, the microstructural properties of nanosized TiO2 were studied by HREM, ED, XRD, SAXS and Raman spectroscopy. An method of determining nanosized TiO2 grain size based on low-frequency Raman scattering is presented.
