Abstract: PURPOSE: A photo electrode for a dye sensitized solar cell including silica particles coated with titanium dioxide and a manufacturing method thereof are provided to manufacture a light scattering electrode which satisfies a shape control and a light property by forming a titanium dioxide layer after the silica particles are made. CONSTITUTION: The surfaces of silica particles are coated with titanium dioxide. A titanium dioxide is crystallized by thermally processing silica nano particles coated with titanium dioxide. The silica nano particle is made with a sol-gel method by mixing silicon-contained alkoxide compound and organic solvent. The average thickness of the titanium dioxide is 5 nm to 50 nm. The average diameter of the silica particle is 50 um to 1 um.

Abstract: PURPOSE: An inversion photonic crystal structure, a manufacturing method, a solar cell thereof, and a manufacturing method thereof are provided to improve a specific surface area by additionally forming a nano-sized porous part. CONSTITUTION: A light absorption layer(351), which contains TiO2, is formed on a transparent conductive board(300). A plurality of photonic crystal particles(311) are formed to be arranged on the light absorption layer at a uniform interval. A solution is filled between the photonic crystal particles by coating a solution(320) which mixes a TiO2 precursor and a surfactant. An optical scattering layer is formed by eliminating the photonic crystal particles and the surfactant.
