PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell capable of keeping an output voltage high as a whole by using a conductive material having low resistance.SOLUTION: A dye-sensitized solar cell 10 is composed of four power generation cells 28A-28D. Negative electrodes 18A-18D thereof face positive electrodes 38A-38D, an electrolyte 74 is sealed between them, and power generation layers 24A-24D are brought into contact with the electrolyte. On one principle surface of a polyimide layer 32 on which the positive electrodes 38A-38D are formed, wiring layers 44A-44D corresponding to the positive electrodes 38A-38D are provided at positions where they overlap with both of the corresponding positive electrodes and the adjoining positive electrodes. The wiring layers 44A-44D are connected to through holes 52A-52D passing through the polyimide layer 32 by conductors 54. The negative electrode of the power generation cell is connected to the wiring layer connected to the adjoining positive electrode of the power generation cell on the peripheral side, except for the wiring layers and negative electrodes where lead-out terminal parts are formed. |
