  • Patent number: 7863448
    Abstract: Disclosed is a novel dye for use in a photoelectronic device, wherein the photoelectronic device is comprised of a photoanode comprising the dye. According to the novel dye, the dye is derived through the introduction of a group which narrows the dihedral angle of the dye ligand as well as through the introduction of conjugated groups. Since the dye has improved light sensitivity and absorption properties, it can be used to fabricate a photoelectronic device with high power conversion efficiency.

  • Patent number: 7626115
    Abstract: Disclosed are a novel dye, having a dispersant functional group to simultaneously exhibit a dye function and a dispersant function, and a dye-sensitized solar cell including the same. According to this invention, the dye may simultaneously manifest a dye function for absorbing light, made possible by being adsorbed on the entire surface of metal oxide particles, to thus produce excited electrons which are then transferred into a conduction band of metal oxide, and a dispersant function for preventing the agglomeration of the particles to thus improve the uniformity of the metal oxide particles in a paste and film density.
