Research on Polycrystalline Solar Silicon-A High-Purity Pilot Plan Development

摘要

Advances in the photovoltaic (PV) industry have resulted in a series of novel technologies involved in high-purity polycrystalline silicon (PSi) manufacturing. Until recently, the demand of high-purity PSi to satisfy the PV demand was extremely lower than those focused on the microelectronics industry. Nevertheless, since last year this trend has begun to witness changes in the opposite direction. Although the maximum purity is still required by microelectronics, referred to as 11Ns, the PV solar energy industry requires the preponderant PSi (6Ns - 9Ns) produced worldwide.
