DYE-SENSITIZED SOLAR CELL AND MANUFACTURING METHOD THEREOF USING BINDER HAVING HYDROXY GROUP AND CARBOXYL GROUP

摘要

A dye-sensitized solar cell using a copolymer binder including a hydroxy group and a carboxyl group and a manufacturing method thereof are provided to increase an open circuit voltage and short circuit current by using the copolymer. A relative electrode includes a light-transmitting material(10), a conductive light-transmitting layer(20), and a platinum layer(30). An optical electrode includes a copolymer binder comprising a hydroxy group and a carboxyl group, a mixture layer comprising a transition metal oxide, and a conductive light-transmitting layer. An electrolyte solution(50) is positioned between the relative electrode and the optical electrode. The copolymer binder comprising the hydroxy group and the carboxyl group is composed of a styrene-based monomer comprising a vinyl group, an acrylate-based monomer comprising the hydroxy group, and a methacrylic acid-based monomer including the carboxyl group.
