Polycrystalline silicon: applications, and properties
Polycrystalline silicon is a material that is used to make solar panels and in electronics. Here we explain it to you. Polycrystalline silicon is a material made of misaligned (polycrystalline) silicon crystal. It occupies an intermediate position between amorphous silicon, in which there is no long-range order, and monocrystalline silicon.
