PHOTOSENSITIZER CONTAINING BENZOTHIAZOLE FOR PHOTOVOLTAIC CELL, AND PHOTOVOLTAIC CELL INCLUDING THE SAME

摘要

PURPOSE: Dye for dye-sensitized solar battery is provided to have high photo absorption degree and absorption degree within 400-550 nm, and to able to remarkably improve photo-electric conversion efficiency when used as a sensitizer for a dye-sensitized solar battery.;CONSTITUTION: Dye for dye-sensitized solar battery comprises a structure in chemical formula 1. In chemical formula 1, D1 and D2 is selected from a group consisting of aromatic hydrocarbon group, substituted or unsubstituted heterocyclic groups, and combinations thereof, B and C is selected from a substituted or unsubstituted aromatic hydro carbon group, a substituted or unsubstituted heterocyclic group, a vinyl group, a substituted or unsubstituted polyvinyl group, and a combination thereof, and A is an acidic functional group.;COPYRIGHT KIPO 2013
