Abstract
The present invention provides a method for fabricating a working electrode. The method comprises the following steps: providing a photoelectrode, which comprises a conductive substrate with a semiconductor material; providing a dye solution, which comprises a dye dissolved in a solvent; and applying a voltage for conducting an electrophoresis to adsorb said dye onto a surface of said semiconductor material. The method of present invention makes the dye adsorbed fast to a surface of a semiconductor material by electrophoresis, and therefore, significantly reduces the time for fabricating a dye-sensitized solar cell.
