ABSTRACT:
Molten silicon is controllably fed into a nip between spaced-apart rollers, converted into a wide ribbon of a desired thickness by passing through such nip and then solidified. The solidified silicon ribbon is then severed into plate-shaped bodies of desired dimension for use in the manufacture of solar cells.
