Slices

Polycrystalline silicon slices for photovoltaic panels

Polycrystalline silicon is produced by melting high-purity silicon in a crucible and then slowly cooling it to form solid ingots. These ingots are then sliced into thin wafers, which are used as the base material for solar cells. Polycrystalline silicon has an impurity level of 1. . Poly-crystalline solar cells are composed from many different silicon crystals, and are the most common type of solar cells produced. Whether you're a solar project developer, an engineering procurement manager, or an investor in renewable energy, understanding this material's role can. . Polycrystalline silicon (poly-Si), also known as multicrystalline silicon (mc-Si), is a material widely used in the manufacturing of photovoltaic (PV) cells.
