Abstract

A dye-sensitized solar cell and method for fabricating the same are provided. The dye-sensitized solar cell includes a photo electrode including a first electrode and a Zn-doped TiO2 porous layer disposed on the first electrode, wherein the Zn-doped TiO2 porous layer absorbs a dye. A second electrode is disposed opposite to the photo electrode, wherein the Zn-doped TiO2 porous layer is disposed between the first and second electrodes. An electrolyte is disposed between the photo electrode and the second electrode.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of Taiwan Patent Application No. 098141672, filed on Dec. 7, 2009, the entirety of which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a dye-sensitized solar cell and a method for fabricating the same, and in particular, to a photo electrode of a dye-sensitized solar cell and a method for fabricating the same.[0004]2. Description of the Related Art[0005]Solar energy is a promising alternative energy source. Developments in solar energy technology are driven by the fact that solar energy is continuous and sustainable. Also, solar energy is environmentally friendly.[0006]Generation of solar energy requires solar cells. Simplistically, electricity is generated by circuitry, generated by illumination of a material to generate electrons and holes. For example, a dye-sensitized solar cell (DSSC) is formed by sintering a semico...
