Abstract

Disclosed are a dye-sensitized solar cell module and a method for manufacturing the same. Particularly, the dye-sensitized solar cell module includes alkali-free thin glass having a reduced thickness instead of the conventional soda-lime as a glass material to manufacture a dye-sensitized solar cell module, such that a working electrode and a counter electrode of the dye-sensitized solar cell module, respectively, have a thickness and a weight reduced by about 70 to 80% without a bending phenomenon or performance degradation of glass. Such dye-sensitized solar cell module of the present invention is suitably applied as a vehicular component that requires reducing weight
