  • Nanoparticle having imidazolium salt chemically bound thereto, method of preparing the same, and nanogel electrolyte for dye-sensitive solar cell comprising the same
    Patent number: 8808565
    Abstract: A nanoparticle to which an imidazolium salt is chemically bonded, a method of preparing the same, and a nanogel electrolyte for dye-sensitized solar cells comprising the same are disclosed. The present invention may provide a dye-sensitive solar cell with good economic feasibility, stability and photoelectric conversion efficiency using the nanogel electrolyte, wherein the nanogel electrolyte may reduce the concentration of ionic liquids and preparation costs while improving economic feasibility, long term stability, and photoelectric conversion efficiency.
    Type: Grant
