DYE-SENSITIZED SOLAR CELL OR SUB-MODULE THEREOF

摘要

The present invention relates to a dye-sensitized solar cell or a sub-module thereof. The dye-sensitized solar cell comprises a photoelectrode, a transparent electrode, and an electrolyte connecting two electrodes electrically. The photoelectrode and transparent electrode are formed on the same surface, wherein the two electrodes are electrically insulated in the absence of the electrolyte. According to the present invention, a transparent conductive oxide-coated area may be reduced by half through the formation of the photoelectrode and a catalyst electrode on one substrate. As a result, the production cost of the dye-sensitized solar cell can be reduced significantly because the coating of the transparent conductive oxide-coated area is the greatest expense in the production of the dye-sensitized solar cell. In addition, general glass, metal thin film, and polymer substrate, which are not coated with a transparent conductive oxide thin film, can be used for the opposite side of the substrate where the electrodes are formed, as an opposed substrate. Thus, more kinds of opposed substrates can be used depending on their applications.
