Solar Grade Silicon
Scrap silicon from semiconductor integrated circuit fabrication can sometimes be reused for solar photovoltaic device manufacturing.
Historically, a large percentage of the silicon used as starting material for solar devices originated from semiconductor waste.
With our powerful, global infrastructure, Advantiv maintains extensive relationships with producers and consumers of scrap silicon, worldwide!
Our capabilities include reclaiming and recycling of used silicon, including bare, coated and patterned silicon wafers.
Unlike solar device manufacturers who buy only P-Type silicon with resistivity > 1Ω-cm, Advantiv can buy all material, including N-Type and resistivity < 1Ω-cm.
N-type and low resistivity materials are directed to our partners who utilize N-type and low resistivity substrates.
If you would like to buy or sell scrap silicon, please contact us.
