• Polysilicon from Sand to Solar Cells, it Starts Here

    Oct 26, 2014· Summary: Polysilicon, a highly refined form of silicon, is the starting material for solar cells. For silicon-based solar cells, polysilicon is the starting material. What is polysilicon, and how is a silicon cell made from polysilicon Polysilicon is formed from Quartzite, a form of quartz sandstone rock. For simplicity sake, you could consider quartzite as comprising pure sand.
