Dye-sensitized solar cell and electrolyte thereof, and methods of manufacturing dye-sensitized solar cell and electrolyte

A method of manufacturing a dye-sensitized solar cell, the method comprising:

• adding a polymerization initiator to an aqueous solution prepared by dissolving a water-soluble polymer and a crosslinking agent in water to prepare an aqueous solution for molding hydrogels;
• injecting the aqueous solution for molding hydrogels between a working electrode or a counter electrode and a dummy substrate;
• solidifying the aqueous solution for molding hydrogels to mold a hydrogel membrane between the working electrode or the counter electrode and the dummy substrate;
• and
• removing the dummy substrate and attaching the counter electrode or the working electrode to an exposed surface of the hydrogel membrane.

A method of manufacturing an electrolyte for dye-sensitized solar cells, the method comprising:

• preparing a hydrogel membrane;
