Title:

NOVEL RUTHENIUM-BASED DYE AND METHOD FOR PREPARING SAME

Document Type and Number:

WIPO Patent Application WO/2016/032266

Kind Code:

A1

Abstract:

The present invention relates to a novel ruthenium-based dye and a method for preparing the same and, more specifically, to a bipyridine-based ruthenium dye which prevents an interaction with I2 of an electrolyte by introducing a hydrophobic group combined with oxygen into a ligand site; exhibits improved photoelectric conversion efficiency and long-term stability, thereby greatly improving efficiency and lifespan of a solar cell; and is synthesized by a relatively simple method, thereby reducing manufacturing costs. The bipyridine-based ruthenium dye of the present invention is used as a dye in a dye-sensitized solar cell (DSSC), and thus has higher efficiency and better long-term stability than existing dyes, thereby significantly improving efficiency of the solar cell.
