BLOCKING LAYER OF PARTICLE MEANS FOR DYE-SENSITIZIED SOLAR CELL AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A corpuscular type blocking layer for a dye sensitized solar cell and a manufacturing method thereof are provided to simplify a manufacturing process by simultaneously firing the blocking layer and a photo electrode layer after the blocking layer is dried at low temperatures. CONSTITUTION: Crystalline metal oxide nano particles are dispersed in solvents. The size of the crystalline metal oxide nano particle is 5 nm or less. A film is formed by spraying the solvents with the dispersed crystalline metal oxide nano particles on a conductive substrate. The solvents are removed from the conductive substrate with the film. The block layer and the photo electrode layer are simultaneously fired.
