METHOD FOR FORMING CASTING MOLD, METHOD FOR MANUFACTURING SUBSTRATE FOR SOLAR CELL ELEMENT, METHOD FOR MANUFACTURING SOLAR CELL ELEMENT AND CASTING MOLD FOR MANUFACTURING SILICON INGOT

摘要

PROBLEM TO BE SOLVED: To provide a solar cell element having excellent characteristics and a method for manufacturing a substrate constituting the solar cell element without a pulverizing step and particularly to provide a method for forming the casting mold for manufacturing silicon ingot suitable for obtaining the substrate.;SOLUTION: The method for forming the casting mold includes a step of: forming body by kneading ceramic powder containing silicon nitride powder and a first binder solution; a step of: forming slurry by adding a second binder solution to the body; and a step of forming a mold releasing layer by applying the slurry to the surface of a casting mold base body.;COPYRIGHT: (C)2010,JPO&INPIT
