1. This polysilicon wafer has undergone a good edging process. The process we use is an important step in the fabrication of silicon wafers to reduce wafer breakage in the remaining manufacturing process or future device manufacturing processes. The edge of the finished product is highly polished, so its cleaning effect is improved and the damage is reduced by up to 400%.
2. The price of the polysilicon wafer is lower than that of the single crystal plate, and the polycrystalline plate is made of less silicon. The process of producing polycrystalline silicon cells is simpler and less expensive than the production of monocrystalline silicon cells. The amount of wasted silicon of this polysilicon wafer is also less than that of single crystal panel production. Polycrystalline silicon is in the form of high purity polycrystalline silicon for the manufacture of solar photovoltaic cells.
