Abstract
A transparent electrode having thermal stability, composed of a transparent conductive material containing a pentavalent element, a method of fabricating the same, and a dye-sensitized solar cell including the electrode. The transparent electrode having thermal stability does not substantially deteriorate even when it is exposed to high temperatures and its conductivity is not reduced. Thus, the dye-sensitized solar cell including the electrode can have improved performance.
