PURPOSE: A method for manufacturing a photoelectrode using a chemical bath deposition method, the photoelectrode manufactured by the same, and a dye-sensitized solar cell are provided to reduce the processing time by directly forming the photoelectrode on a transparent conductive substrate or a seed layer which is formed on the transparent conductive substrate. CONSTITUTION: A metal oxide layer (40) is formed on a transparent conductive substrate (10). The metal oxide layer includes a first metal oxide particle (20) and a second metal oxide particle (30). Photosensitive dyes are absorbed on the metal oxide layer. A metal oxide core-transition metal oxide shell (50) is formed by coating the transparent conductive substrate including the metal oxide layer with a transition metal oxide shell. The calcination of the metal oxide core-transition metal oxide shell is performed on the transparent conductive substrate.

PURPOSE: A porous transition metal oxide structure, a manufacturing method thereof, a photoelectrode including the same, and a dye-sensitized solar cell including the photoelectrode are provided to prevent a low photocurrent density by forming the porous transition metal oxide structure with a porous heterogeneous composite structure using a self-assembly method of a polymer particle. CONSTITUTION: A polymer sacrificial layer with a 3D porous structure is formed on a base material. A first transition metal oxide precursor (10) or a first transition metal oxide particle is injected to the polymer sacrificial layer. A first transition metal oxide structure with a pore (20) which is three-dimensionally arranged is formed by removing the polymer sacrificial layer. A second transition metal oxide layer (30) is formed by coating the inner wall of the pore with a second transition metal oxide material. A third transition metal oxide layer (40) is formed by coating the second transition metal layer with a third transition metal oxide material.

The first transition metal oxide structure has pores arranged in three dimensions. The second transition metal oxide particles(30) are arranged in the 3D pores to form the second transition metal oxide structure. A manufacturing method of the porous transition metal oxide structure comprises the following steps: forming a sacrifice layer containing polymer colloidal particles on a substrate; injecting the first transition metal oxide precursor or the first transition metal oxide particles into the sacrifice layer; forming the first transition metal oxide structure having pores arranged in three dimensions by removing the sacrifice layer; and forming the second transition metal oxide structure by injecting the second transition metal oxide particles into the pores.
