Patent ID: 8563346

Claim:
A method for manufacturing an electrode of a dye-sensitized solar cell using an inkjet printing process, the method comprising: depositing a barrier layer on a transparent substrate; forming a metal electrode on the barrier layer by jetting an ink solution containing nano metal powder on the barrier layer; and forming a transparent conductive layer on the barrier layer on which the metal electrode is formed, the transparent conductive layer configured to protect the metal electrode from a liquid electrolyte; forming a working electrode and a counter electrode by coating metal oxide with dye on a predetermined portion of the transparent conductive layer; and bonding the working electrode and the counter electrode, and filling electrolyte between the working electrode and the counter electrode, wherein the ink solution is formed by mixing an ink composition with a polar or nonpolar solvent, wherein the ink composition contains a nano metal powder having a particle size of about 20 nm to about 100 nm, and wherein the amount of nano metal powder is about 10 wt % to about 95 wt %, and the amount of the polar or nonpolar solvent is about 5 wt % to about 90 wt % based on the total weight of the ink composition.
