NOVEL ANCHORING LIGANDS FOR SENSITIZERS OF DYE-SENSITIZED PHOTOVOLTAIC DEVICES

摘要

The present invention provides novel dyes for dye sensitized photovoltaic conversion devices. The dyes contain novel anchoring ligands, which have a vinyl or phenylethenyl moiety incorporated in the anchoring bipyridine. Such dyes exhibit an increased molar extinction coefficient and enhanced red response in the visible regions.
