    Abstract: Provided is a dye-sensitized solar cell. Specifically, the present invention provides a dye-sensitized solar cell which is designed to reduce the production cost, improve productivity and increase energy efficiency by using a carbon electrode as a counter electrode, and a manufacturing method thereof. The dye-sensitized solar cell according to the present invention is characterized by comprising a working electrode, a counter electrode, and an electrolytic layer separating the two electrodes, wherein the counter electrode comprises a carbon electrode formed on a first transparent substrate, wherein the carbon electrode is a conductive transparent carbon electrode. According to the present invention, it is possible to remarkably reduce the production cost by using a relatively low-cost material, i.e. carbon electrode, and improve the solar cell efficiency by preventing oxidation with the electrolytic layer owing to corrosion and oxidation resistance of the carbon electrode.
