ABSTRACT:
Disclosed is a dye-sensitized solar cell comprising a gel electrolyte that contains a gelling agent and an electrolyte, wherein the gelling agent contains at least one kind of a polymer selected from the group consisting of a first polymer in which polysulfonic acid is crosslinked by a metal ion having a valency of not less than two, a second polymer in which polycarboxylic acid is crosslinked by a metal ion having a valency of not less than two, a third polymer in which a quaternary ammonium salt of polysulfonic acid is crosslinked by a metal ion having a valency of not less than two and a fourth polymer in which a quaternary ammonium salt of polycarboxylic acid is crosslinked by a metal ion having a valency of not less than two.
