    • A method of manufacturing a graphene-containing electrolyte includes, in the order recited: (a) deoxidizing graphene oxide to form graphene; (b) dissolving the graphene in a carbonate solvent to provide a graphene-containing solution; and (c) adding an oxidation-reduction agent composed of 1-butyl-2,3-dimethylimidazolium iodide (BDI) and optionally iodine (I2) into the graphene-containing solution to provide the graphene-containing electrolyte. Deoxidizing the graphene oxide may be accomplished by dissolving the graphene oxide in an aqueous solvent that is a mixture of water and an alkyl imidazole-based iodine to form a solution; and centrifuging the solution to obtain the graphene. A dye-sensitized solar cell may include the graphene-containing electrolyte to fill a space defined between first and second electrodes.
    • 制造含石墨烯的电解质的方法按照以下顺序包括:(a)使氧化石墨烯氧化形成石墨烯; (b)将石墨烯溶于碳酸酯溶剂中以提供含石墨烯溶液; 和(c)将由1-丁基-2,3-二甲基咪唑碘化物(BDI)和任选的碘(I 2)组成的氧化还原剂加入到含石墨烯溶液中以提供含石墨烯的电解质。 氧化石墨烯可以通过将石墨烯氧化物溶解在水和基于烷基咪唑的碘的混合物的水性溶剂中来形成溶液来实现, 并离心溶液以获得石墨烯。 染料敏化太阳能电池可以包括含石墨烯的电解质,以填充限定在第一和第二电极之间的空间。
