Abstract
A dye-sensitized photoelectric converter with enhanced light absorptance and photoelectric conversion efficiency is provided. The dye-sensitized photoelectric converter includes a transparent substrate (e.g., glass), a (negative) electrode composed of a transparent conductive layer such as FTO (fluorine-doped tin(IV) oxide SnO), a semiconductor layer holding multiple types of photosensitizing dyes, an electrolyte layer, a counter (positive) electrode, a counter substrate, and a sealing medium (not illustrated). In some embodiments, the multiple types of photosensitizing dyes have minimum excitation energies that are different from one another. In some embodiments, the multiple types of dyes have steric configurations that are different relative to one another.
