Abstract
This invention relates to a method for making an electrolyte composition of a dye-sensitized solar cell comprising utilizing exfoliated clay nanoplatelets and the method for rapidly encapsulating cations. The electrolyte composition mainly includes exfoliated clay nanoplatelets, an ionic liquid and iodine. The method for rapidly encapsulating cation comprises adding the exfoliated clay nanoplatelets into a cationic solution, wherein the exfoliated clay nanoplatelets encapsulates cations and recovers into a layered structure such that phase separation of the solution occurs; and filtrating the solution to separate the clay nanoplatelets encapsulating the cations. The exfoliated clay nanoplatelets have a unique property of encapsulation for the cations, is suitable for use in an electrolyte composition for dye-sensitized solar cells, cationic drug encapsulation and environmental protection.
