<P>PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell superbly maintaining photoelectric conversion efficiency for a long period of time, by preventing exfoliation and damage of a sealing part due to swelling of electrolytic solution, and preventing decrease of the electrolytic solution in an inner space. <P>SOLUTION: A pressure regulating means 21 of the dye-sensitized solar cell consists of a tank 25 equipped with a storage part 26 capable of housing the electrolytic solution 14. The tank 25 is made of, for instance, a bellows-shaped elastic cylindrical member. Such a tank 25 has a bellows part expanded and contracted along an L-direction accordance with volume variation due to temperature change of the electrolytic solution 14 to change a volume of the electrolytic solution 14 capable of being housed in the storage part 26. <P>COPYRIGHT: (C)2009,JPO&INPIT |
