Abstract

Some recent results from our laboratory on the properties of microporous colloidal TiO₂ film electrodes are summarized. The photoelectrochemical properties of the colloidal film electrodes are compared with solid transparent thin films of TiO₂. In particular the information that can be derived from analysis of the action spectra for front and back side illumination of the films is given. The mechanism of charge separation in the colloidal film is qualitatively discussed in terms of the kinetics at the electrode-electrolyte interface, and some effects of the presence of O₂ in the electrolyte are demonstrated. Finally we also briefly report the solar energy efficiency from measurements on dye-sensitized TiO₂ film electrodes in solar cells.
