The products made by directional solidification of silicon materials. In general, silicon materials including raw polysilicon and monocrystalline silicon back materials, raw poly-silicon is generally referred to as the material, its purity is high, the price is also expensive; monocrystalline silicon back materials such as monocrystalline silicon rod, edge leather, Guo, the battery after cleaning treatment of raw materials and so on.
Silicon in the single crystal furnace (in the solar-grade monocrystalline silicon production process in the direct-pull furnace is more common) and then through a series of processes can grow into monocrystalline silicon Bonzi, the silicon ingot is processed by subsequent machining, the monocrystalline silicon ingot is obtained, and the wafer is processed by slicing machine.
