METHOD FOR MANUFACTURING MULTI-JUNCTION SOLAR CELL

摘要

Provided is a method for manufacturing a multi-junction solar cell having high conversion efficiency, by which a multi-junction solar cell is able to be manufactured in a short time by a simple process. A method for manufacturing a multi-junction solar cell according to the present invention is provided with: a step a for forming a coating film of an aluminum paste on one surface of a silicon substrate; a step b for subjecting the silicon substrate and the coating film to a firing process; and a step c for laminating a group III-V compound solar cell layer on the other surface of the silicon substrate by wafer bonding or by crystal growth.
