Polysilicon

Polycrystalline material: polysilicon, is a form of elemental silicon. Molten elemental silicon in extreme cold conditions solidification, the silicon atom to diamond crystal lattice are arranged in many forms the nucleation, such as these forms of different grain grown faces orientation, then these grain together, into polycrystalline silicon crystals.
Use value: from the current international solar cell development process can see the development trend for monocrystalline silicon and polycrystalline silicon, ribbon silicon, film materials (including microcrystalline silicon thin film, compounds, the film and dye film).
