Apr 20, 2019 · Just like monocrystalline panels, silicon is also the primary component of a polycrystalline solar panel. But instead of a single silicon crystal, manufacturers use -crystals of silicon for the production of this solar panel. They melt different fragments of silicon to create wafers and then attach them to the panel.

Cz Monocrystalline Silicon Production - PV-Manufacturing

Monocrystalline silicon (mono-Si or c-Si) is silicon which consists of a continuous solid single crystal. The silicon grown for photovoltaic (PV) applications is grown in a cylindrical form with a typical diameter of 8 inches (~200 mm). The surface of the cylinder is then trimmed to make a pseudo-square shape.
