POROUS TRANSITION METAL OXIDE STRUCTURE, PREPARING METHOD OF THE SAME, PHOTOELECTRODE INCLUDING THE SAME, AND DYE-SENSITIZED SOLAR CELL INCLUDING THE PHOTOELECTRODE

摘要

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.
