ABSTRACT:
A dye-sensitized solar cell using an ion-bound oligomer complex is provided. The dye-sensitized solar cell comprises an electrolyte, comprising a first oligomer having a C5-30heteroaryl group containing a nitrogen heteroatom as a basic functional group at both ends of the molecule, mixed with a second oligomer having an acidic functional group selected from among carboxylic acid, phosphoric acid, and sulfonic acid, at both ends of the molecule, to thus form a salt, which then leads to an ion-bound oligomer complex that constitutes the electrolyte. The solar cell exhibits excellent mechanical properties, can be manufactured conveniently, and can have a high energy conversion efficiency.
