Sensitizing dye solution working electrode prepared thereby and dye-sensitized solar cell comprising the same

摘要

The present invention relates to a method of adsorbing a dye for a dye-sensitized solar cell, a photoelectrode using the dye, and a dye-sensitized solar cell using the same, which comprises the steps of coating a paste containing metal oxide nanoparticles on a titanium oxide thin film, Adding an additive capable of accelerating dye adsorption to the photosensitive dye solution, and immersing the porous film in a photosensitive dye dispersed in an organic solvent to adsorb the photosensitive dye on the surface of the porous film, thereby shortening the time for dye adsorption through the additive , Even if the adsorption time is shortened, the desorption of dye does not occur in the long-term or short-term, and the long-term stability of the solar cell can be ensured.
