A photo electrode for a dye-sensitized solar cell including a hollow sphere metal oxide nano particle and a manufacturing method thereof are provided to improve energy conversion efficiency by absorbing the dye, generating a photoelectron, and obtaining a light diffusion effect. A photo electrode for a dye-sensitized solar cell includes a conductive substrate, a porous film, and a light diffusion layer porous film. The porous film having a metal oxide nano particle layer in which the dye is absorbed is formed in the conductive substrate. The light diffusion layer porous film having the hollow sphere metal oxide nano particle layer in which the dye is absorbed is formed on the metal oxide layer.
