A dye-sensitized solar cell is provided having at least one organic compound to absorb solar radiation and donate electrons, at least one semiconductor to transport electrons, and at least one hole transporting material formed of a water-based electrolyte gel that includes at least one polymeric compound and at least one electrolyte solution. Preparation of the water based gel includes gelling at least one hydrophilic polymer that is present at least in a concentration, depending on molecular weight and/or degree of hydrolyses and/or degree of polymerization, sufficient to form the gel from the aqueous solution.
