Solar Silicon

Designed specifically to meet the needs of the solar industry, our solar silicon can help PV module manufacturers reduce costs while continuing to meet stringent customer performance expectations. Silicor’s solar silicon is a compelling alternative to costly electronic-grade (EG) silicon produced through the Siemens process or with fluidized bed reactor technology.
Silicor's solar silicon:
Achieves in-line PV cell conversion efficiencies comparable to cells manufactured using primarily EG silicon
Enables module manufacturers to improve margins
Can be used as a drop-in replacement for EG silicon, or as part of a blend
Is optimized to minimize the presence of dopants, particularly boron and phosphorus
Our solar silicon already powers more than 20 million PV cells worldwide, and modules created with our solar silicon have earned certifications from UL, IEC and TÜV Rheinland.
Silicor’s material has also demonstrated exceptional performance at a number of module testing sites, including the National Renewable Energy Laboratory’s headquarters and a facility in Sunnyvale, California.
