Polysilicon from Sand to Solar Cells, it Starts Here

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.

Silane Wikipedia

Silane is an inorganic compound with chemical formula, Si H 4, making it a group 14 hydride.It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, somewhat similar to that of acetic acid. Silane is of practical interest as a precursor to elemental silicon. "Silanes" refers to many compounds with four substituents on silicon, including an organosilicon compound.
