Abstract:
1. A dye-sensitized solar cell having multiple photoelectric conversion elements, where each element has a negative electrode on which a dye-sensitized generation layer is provided, as well as a positive electrode opposingly positioned in a manner sandwiching the generation layer, and an electrolytic solution is sealed in a space formed by a sealant provided around the negative electrode and positive electrode; wherein: the multiple photoelectric conversion elements are positioned around the dye-sensitized solar cell except at its approximate center; multiple wiring layers corresponding to the positive electrodes of multiple photoelectric conversion elements are positioned, via an insulation layer, on a non-optical receiving side of the dye-sensitized solar cell; and the dye-sensitized solar cell comprises: a negative electrode terminal part which is connected to the negative electrode of one of the multiple photoelectric conversion elements and used for taking out the electrodes at the approximate center; a first electrode coupling means for electrically connecting the positive electrode and corresponding wiring layer; a positive electrode terminal part which is formed on the wiring layer connected to the positive electrode of another element among the multiple photoelectric conversion elements other than the one of the multiple photoelectric conversion elements and which is used for taking out the electrodes at the approximate center; and a second electrode coupling means for connecting adjacent photoelectric conversion elements by electrically connecting the negative electrode of an element on which the negative electrode terminal part is not provided, with a wiring layer on which the positive electrode terminal part is not provided, on an outer periphery side of the dye-sensitized solar cell, wherein the wiring layer is formed at a position overlapping as viewed from above, via the insulation layer, with both the positive electrode of the corresponding photoelectric conversion element and the positive electrode of another photoelectric conversion element adjacent to the corresponding photoelectric conversion element.
