GEL-TYPE POLYMER ELECTROLYTE COMPOSITION AND DYE-SENSITIZED SOLAR CELL INCLUDING SAME

摘要

The present invention relates to a gel-type polymer electrolyte composition and a dye-sensitized solar cell including same. The gel-type polymer electrolyte composition of the present invention, including a polyethylene glycol-polyproylene glycol-polyethylene glycol (PEG-PPG-PEG) block copolymer, can have low crystallinity without the problem of electrolyte leakage, thereby allowing easy injection of an electrolyte solution as the dye-sensitization of the solar cell does not lead to blockage of the inlet for electrolyte injection, and thereby allowing a longer lifespan, which results in high photoelectric conversion efficiency, and thus rendering the present invention useful for the electrolyte in the dye-sensitized solar cell.
