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.
