polysilicon
Solar panel material
Polysilicon is silicon composed of many small crystals rather than a single continuous crystal structure.
It serves as the raw material for semiconductor manufacturing and solar cell production.
Wafers are cut from polysilicon ingots, then processed into the chips that power electronics.
The term distinguishes it from monocrystalline silicon, which has superior but more expensive properties.
