1. A process for manufacturing polycrystalline silicon sheets for use in solar cells, consisting in : - depositing a film of polycrystalline silicon over the entire surface of a carbon strip (4) by passing the strip through a bat (2) of molten silicon, characterized in that it further consists in : - cutting off the edges of said strip (4) when covered with the silicon film so as to obtain a strip (11) comprising a respective layer (12, 13) of silicon on each side of a carbon sheet (14), and - eliminating the carbon sheet by chemical or electrochemical oxidation so as to obtain two sheets of silicon. |
