Title (EN) METHOD FOR MAKING SILICON FOR SOLAR CELLS AND OTHER APPLICATIONS
(FR) PROCÉDÉ DE FABRICATION DE SILICIUM POUR CELLULES SOLAIRES ET POUR D'AUTRES APPLICATIONS
Abstract: front page image
(EN)A method for preparation of high purity silicon suitable for photovoltaic cells using reduction of silica, which is pre-purified in an aqueous solution, in presence of a reducing agent, preferably carbonaceous agent, where the pre-purified silica has a low amount of boron suitable for photovoltaic cells is described.
(FR)La présente invention concerne un procédé de préparation de silicium de haute pureté qui convient pour des cellules photovoltaïques au moyen de la réduction du silice, qui est pré-purifié dans une solution aqueuse en présence d'un agent de réduction, de préférence un agent charbonneux, le silice pré-purifié possédant une faible quantité de bore, ce qui convient pour des cellules photovoltaïques.
