Procedure based on the EFG procedure for the production of ribbon-shaped bodies from crystalline solid materials

摘要

A method is provided for producing solar cells employing slightly curved or nearly flat monocrystalline silicon ribbons. The ribbons are formed by cutting or slicing monocrystalline hollow tubes along their lengths, the tubes having been formed according to crystal growing processes disclosed in U.S. Pat. No. 3,591,348.
