PURPOSE: A polymer electrolyte nanocomposite is provided to decrease crystallinity of a polymer matrix, to increase ion conductivity, to improve surface contact, and to improve energy conversion efficiency of a dye-sensitized solar battery by mixing the polymer matrix and polyhedral oligomeric silsesquioxane-based nanoparticles. CONSTITUTION: An organic-inorganic hybrid polymer electrolyte nanocomposite comprises a matrix polymer, a nanoparticle, and oxidation-reduction derivatives. A weight average molecular weight of the matrix polymer is 10^4 ~ 10^6 g/mol, the glass transition temperature is -60 to -20°C. The matrix polymer comprises a polar group in the backbone thereof. The polar group is one or more kinds selected from a group consisting of -O-, -CN-, -COO-, -CF-, and -CCl-. A dye-sensitized solar battery comprises a working electrode, the electrolyte, and a counter electrode. |
