<p>The present invention relates to a counter electrode for a dye-sensitized solar cell including a conductive polymer and a metal nanoparticle and a method for manufacturing the same and, more particularly, to a counter electrode for a dye-sensitized solar cell including a composite material having metal nanoparticles dispersed in a conductive polymer layer, a method for manufacturing a dye-sensitized solar cell, which comprises: a step 1 of manufacturing a metal nanoparticle-conductive polymer composite material by adding a reducing agent after mixing a conductive polymer solution and a metal precursor; a step 2 of spin-coating the composite material of step 1 on a substrate coated with a transparent electrode; and a step 3 of manufacturing a counter electrode by heat-treating the substrate coated with the composite material of step 2, and a dye-sensitized solar cell manufactured by the manufacturing method. The counter electrode of the present invention has transparency, flexibility, and conductivity, which are the advantages of the conductive polymer and the metal nanoparticle, and can be provided at a relatively low price compared to the case using only a metal material. Also, the method for manufacturing a counter electrode according to the present invention enables a solution coating process to simplify the process and enables a low temperature process to be applied to a flexible substrate. Furthermore, since the conductive polymer can disperse the metal nanoparticles and maintain stability at the same time, the deterioration of the conductivity and charge transfer characteristics of the metal nanoparticle due to the addition of a stabilizer can be prevented.</p> |
