ABSTRACT:
A method is provided for producing flat substantially monocrystalline ribbons, e.g. silicon ribbons for use in making flat solar cells. The ribbons are produced by growing substantially monocrystalline flat hollow tubes, and then excising the edge portions of the tubes so that the flat sides of the tubes form discrete ribbons.
