Solar-grade silicon
Intermediate-grade silicon utilized for manufacturing of photovoltaic cells. It is cheaper compared to electronic-grade silicon.Crystalline silicon - Wikipedia,Crystalline silicon (c-Si) is the crystalline forms of silicon, either polycrystalline silicon (poly-Si, consisting of small crystals), or monocrystalline silicon (mono-Si, a continuous crystal). Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells. These cells are assembled into solar panels as part of a photovoltaic system to generate solar power from sunlight. In electronics, crystalline silicon is typically the monocrystalline form of silicon, and is used forSolar Grade Silicon - Ferroglobe,SOLAR GRADE SILICON IS A HIGH PURITY MATERIAL TO BE USED AS FEEDSTOCK IN INGOT CRYSTALLIZATION FOR SOLAR POWER CELL'S WAFERS.

It is cheaper compared to electronic-grade silicon.Silicon Alloy – Solar Grade Silicon | Thermo-Calc Software,Impurities in metallurgical grade silicon can drastically modify the material properties relevant for solar cells. For example, transition metal impurities such as iron, copper, and chromium can shorten the lifetime of excited carriers in the silicon solar cell and are thus detrimental to the cell efficiency. Their removal from silicon is therefore an important issue in silicon solar cell,
New Method of Solar Grade Silicon Production
electronic industry, so named scrap. Usually, scrap is not more that 10% of electronic grade polycrystalline silicon.
