Processes for the preparation of solar-grade silicon and photovoltaic cells |
| abstract |
A process for the manufacture of high-purity elemental silicon is described. The process includes the step of preparing a silica gel composition by reacting at least one organosilane compound with an aqueous composition, so as to form granules of the silica gel. A hydrocarbon species is then decomposed by way of a hydrocarbon cracking reaction in the presence of the silica gel composition, so that carbon resulting from the decomposition of the hydrocarbon species is deposited on the granules of the gel composition. Heating of the carbon-containing silica gel composition to an elevated temperature produces the elemental silicon product. Related methods for making photovoltaic cells, using the elemental silicon, are also described. |
