Abstract: Provided are a composition for a semiconductor electrode that can be sintered at a low temperature, a manufacturing method thereof, and a dye-sensitized solar cell using the composition. The composition for the semiconductor electrode comprises a colloid solution containing a nanocrystalline oxide material and an aqueous base solution. Even though the composition does not include binders, the composition can be sintered at a low temperature. By coating the composition on a conductive substrate and treating the substrate with a solution of TiCl 4 , the sintering between the nanoparticles can be reinforced. The dye-sensitized solar cell manufactured using the composition for the semiconductor electrode can have excellent photoelectric conversion efficiency.

Abstract: Provided are a composite polymer electrolyte for a lithium secondary battery in which a composite polymer matrix multi-layer structure composed of a plurality of polymer matrices with different pore sizes is impregnated with an electrolyte solution, and a method of manufacturing the same. Among the polymer matrices, a microporous polymer matrix with a smaller pore size contains a lithium cationic single-ion conducting inorganic filler, thereby enhancing ionic conductivity, the distribution uniformity of the impregnated electrolyte solution, and maintenance characteristics. The microporous polymer matrix containing the lithium cationic single-ion conducting inorganic filler is coated on a surface of a porous polymer matrix to form the composite polymer matrix multi-layer structure, which is then impregnated with the electrolyte solution, to manufacture the composite polymer electrolyte. The composite polymer electrolyte is used in a unit battery. The composite polymer matrix structure can increase mechanical properties. The introduction of the lithium cationic single-ion conducting inorganic filler can provide excellent ionic conductivity and high rate discharge characteristics.
