Abstract
Disclosed herein are a novel dye for a photoelectric device and a photoelectric device comprising the dye. More particularly, the dye for a photoelectric device incorporates different quaternary ammoniums into a carboxyl or phosphoric acid-substituted bipyridyl ligand of the dye, and a photoelectric device comprising the same. The dye for a photoelectric device as disclosed herein exhibits improved photosensitivity and light absorbing characteristics, thereby making it possible to fabricate a highly efficient photoelectric device when the dye is included in the device.
