Polycrystalline silicon (or semi-crystalline silicon, polysilicon, poly-Si, or simply "poly") is a material consisting of multiple small silicon crystals. Polycrystalline cells can be recognized by a visible grain, a "metal flake effect".OverviewPolycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, form of, used as a raw material by the solar and . Polysilicon. . In single-crystal silicon, also known as, the crystalline framework is homogeneous, which can be recognized by an even external colouring. The entire sample is one single, continuous and unbrok.
