Summary: Polysilicon, a highly refined form of silicon, is the starting material for solar cells. For siliconbased 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.
