Patent number: 7910824Abstract: 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 C5-30 heteroaryl 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.Type: GrantFiled: August 16, 2007Date of Patent: March 22, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Byung Hee Sohn, Sang Cheol Park, Jung Gyu Nam, Won Cheol Jung, Young Jun Park, Yong Soo Kang, Yong Gun Lee
