Abstract: A method for manufacturing crack-free, large-surface silicon crystal bodies for solar cells wherein a carrier member composed of a carbon fiber fabric is coated with silicon by bringing a molten silicon into contact with the carrier member and crystallizing it. In order to improve the wettability, the carrier member is subjected to an activating surface treatment before the coating. The method is useful for continuous manufacture of silicon sheets for solar cells.
