COBALT-BASED COMPOUND FOR SOLAR CELL

WIPO Patent Application WO/2012/118346

A2

The present invention relates to a cobalt-based compound for a solar cell. Particularly, the cobalt-based compound of the invention: is used in an electrolyte system of a dye-sensitized solar cell, thereby enabling the preparation of a dye-sensitized solar cell into a thin film which is thinner than a conventional dye-sensitized solar cell; can improve durability of the dye-sensitized solar cell since it is less corrosive to metals; and particularly improves the efficiency of the dye-sensitized solar cell due to a high redox potential difference.
