PHOTOCATALYST MAKING METHOD USING TRANSITION METAL, AND THE DYE SENSITIZED SOLAR CELLS INCLUDING PHOTOCATALYST

摘要

PURPOSE: A manufacturing method of a photocatalyst having transition metals, and a manufacturing method of a dye-sensitive solar cell including the photocatalyst are provided, which can improve the energy conversion efficiency of the dye sensitized solar cell. CONSTITUTION: A manufacturing method of a photocatalyst including transition metals comprises a step for forming sludge through a centrifuge process, after stirring the photocatalyst in which the transition metal is supported, and a step for creating a photocatalyst particle by calcining and pulverizing the sludge. The transition metal is chrome, vanadium, silver, gold, palladium, platinum, molybdenum, or niobium. A manufacturing method for a dye-sensitized solar cell comprises the following steps: manufacturing paste by using the photocatalyst particle; manufacturing a photoelectrode with the paste; and forming a solar cell with a hot pressing method.
