Abstract: A method for depositing a large-area graphene layer and an apparatus for continuous graphene deposition using the same are disclosed. The method can include forming a titanium (Ti) layer on a substrate by sputtering, reducing the titanium layer by spraying a reductant gas containing a hydrogen gas (H2) and a purge gas onto the titanium layer while moving in a first direction in relation to the substrate and exhausting the reductant gas and the purge gas. The method can also include forming graphene by spraying a reactant gas containing a graphene source and the purge gas onto the titanium layer while moving in a second direction opposite the first direction in relation to the substrate and exhausting the reactant gas and the purge gas.

Abstract: The present invention provides a method for manufacturing an electrode of a dye-sensitized solar cell using an inkjet printing process, an electrode formed thereby, and a dye-sensitized solar cell having the electrode. According to the method, a metal electrode is formed by jetting an ink solution containing nano metal powder on a transparent substrate or a transparent substrate in which a barrier layer is deposited to improve coating performance of a transparent conductive layer. A transparent conductive layer is formed on the transparent substrate on which the metal electrode is formed. The transparent conductive layer protects the metal electrode from liquid electrolyte.
