Zusammenfassung:Starting plate-like silicon bodies matched to the dimensions desired in a product silicon crystal bodies are melted and then crystallized on a horizontal carrier member having a net structure using a heater arrangement. The carrier member is substantially not wettable by molten silicon and preferably consists of a quartz glass fiber fabric and is removable after the crystallization. The method is useful for the manufacture of silicon for solar cells and prevents contaminants from the carrier member from being incorporated into the product silicon crystal body and thereby deteriorating the electrical properties of the solar cells.
