UNIDIRECTIONAL ELECTROLYTE INJECTION HOLE STRUCTURE AND DYE-SENSITIZED SOLAR CELL MODULE HAVING SAME

摘要

The present invention relates to a unidirectional electrolyte injection hole structure for a dye-sensitized solar cell and a dye-sensitized solar cell module having same, and more particularly, to a unidirectional electrolyte injection hole structure for a dye-sensitized solar cell, in which a fluid may pass while an electrolyte is injected into cells and sealing may be maintained by a pressure of the injected electrolyte itself, and a dye-sensitized solar cell module having same. In the unidirectional electrolyte injection hole structure according to the present invention, since unidirectionality is maintained by the pressure of the injected electrolyte itself, the electrolyte may be simply injected through a simplified structure and may efficiently be prevented from leaking. Also, when the electrolyte is insufficient due to long-time use, an electrolyte may be simply filled without a separate structure. Also, in the dye-sensitized solar cell module, since the electrolyte may be injected into the cells constituting the module all at once through an electrolyte path having the unidirectionality defined between the cells without a separate injection hole for each cell, the number of injection electrolyte holes of the dye-sensitized solar cell module may be reduced. Thus, non-generating areas may be reduced, and a cost advantage can be derived.
