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.
