본문내용
The solar cell consists of two conducting glass electrodes in a sandwich configuration, with a redox electrolyte separating the two. On one of these electrodes, a few micron-thick layer of TiO2 is deposited using a colloidal preparation of monodispersed particles of TiO2. The compact layer is porous with a high surface area, allowing monomolecular distribution of dye molecules. After appropriate heat treatment to reduce the resistivity of the film, the electrode with the oxide layer is immersed in the dye solution of interest (typically 2x10-4M in alcohol) for several hours. The porous oxide layer acts like a sponge and there is very efficient uptake of the dye, leading to intense coloration of the film. Molar absorbances of 3 and above are readily obtained within the micron-thick layer with a number of Ru-polypyridyl
