Abstract: Disclosed is a method for adsorbing a dye for a dye-sensitized solar cell. The method includes: coating a paste including metal oxide nanoparticles on the upper surface of a titanium oxide thin film and calcining the coated paste to form a porous film; adding an additive to a sensitizing dye solution to promote the adsorption of the dye; and dipping the porous film in the sensitizing dye solution to adsorb the sensitizing dye onto the surface of the porous film. The sensitizing dye solution is a dispersion of the sensitizing dye in an organic solvent. Also disclosed are a working electrode prepared using the sensitizing dye solution and a dye-sensitized solar cell including the working electrode. The addition of the additive shortens the time of dye adsorption. Despite the shortened adsorption time, the dye does not undergo desorption in the long term as well as in the short term, ensuring long-term stability of the solar cell.
