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.

The way photons interact with solar cells, they can only generate electricity from the sun’s energy up to a certain point. After that point (86 percent) thermal energy, or heat, is created. One way to improve thermodynamic efficiency is to construct multi-junction or tandem solar cells. This improves efficiency by dividing the solar spectrum .
