Title:
COBALT-BASED COMPOUND FOR A SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2012/128512
Kind Code:
A3
Abstract:
The present invention relates to a cobalt-based compound for a solar cell. More particularly, the cobalt-based compound of the present invention is to be used in an electrolyte system of a dye-sensitized solar cell to be produced into a thinner film than existing dye-sensitized solar cells. Further, the cobalt-based compound of the present invention is less corrosive to metals and thus improves the durability of a dye-sensitized solar cell, and particularly, has a large redox potential difference and thus may improve the efficiency of a dye-sensitized solar cell.
