PIGMENT FOR PHOTOELECTRIC CONVERTER, AND PHOTOELECTRIC CONVERSION FILM, ELECTRODE, AND SOLAR CELL USING SAME

摘要

Provided is a pigment for a photoelectric converter that has broad absorption from the visible to the near infrared regions. The pigment for a photoelectric converter comprises at least molecules that contain elemental phosphorus and form coordinate bonds at least at these phosphorus atoms and one type of metal complex that forms coordinate bonds with a terpyridine derivative that has at least one adsorbing group capable of being adsorbed by a metal oxide. The metal complex is the pigment for a photoelectric converter showing absorption derived from spin-forbidden transition.
