Process for making silicium crystals for photovoltaic applications.

摘要

1. A method of obtaining silicon crystals for photovoltaic applications and having a photovoltaic conversion efficiency of not less than 10%, in which the silicon is purified by passing through a plasma jet, the starting material being constituted by monocrystalline or polycrystalline P-type or N-type recyclable silicon waste having a concentration of impurities and a crystallization state such that its resistivity is not less than 0,05 ohm.cm.
