ABSTRACT:
Processes for the continuous deposition of crystalline silicon on graphite substrates, the silicon being undoped or N- or P-doped and the substrates being useful for photovoltaic cells and other electronic devices, the processes comprising placing crystalline silicon in at least one crucible having a capillary port with a vertical axis in its lower part; bringing the silicon to its melting point; bringing a graphite substrate into contact with the pendant drop formed at the lower mouth of the capillary; moving the substrate at a selected speed in a constant predetermined direction; and removing the substrate coated with the crystalline substance at chosen time intervals.
