NOVEL ANCHORING LIGANDS FOR SENSITIZERS OF DYE-SENSITIZED PHOTOVOLTAIC DEVICES

摘要

The present invention relates to novel pyridine compounds that can be used as anchoring ligands in metal-based sensitizing dyes of dye sensitized solar cells (DSC_S). The dyes comprising the polypyridine compounds exhibit improved light harvesting ability and lead to increased conversion efficiencies, in particular in thin TiO₂ film devices.
