Dow Corning Corp. has announced that it has achieved a milestone in solar energy technology: a solar-grade (SoG) silicon derived from metallurgical silicon that exhibits good solar cell performance characteristics when blended with traditional polysilicon feedstock. This new silicon feedstock material, Dow Corning(R) PV 1101 SoG Silicon, is the first commercially available feedstock produced from such technology using large scale manufacturing processes.
This silicon will increase the availability of feedstock to the photovoltaic industry, providing new options to ingot, wafer and cell producers. Dow Corning began bulk production of PV 1101 earlier this summer, and bulk customer shipments began in August. Progressive ramping up of the PV 1101 SoG
Silicon production facility to full speed is currently in progress.
