Monocrystalline Ingots

We commenced production of monocrystalline ingots in March 2009. To produce monocrystalline ingots, we place polysilicon into a quartz crucible in a furnace, where the polysilicon is melted. Then, a thin crystal seed is dipped into the molten silicon to determine the crystal orientation. The seed is rotated and then slowly extracted from the molten silicon to form a single crystal as the molten silicon and crucible cool. Once the single crystals have been grown to pre-determined specifications, they are surface-ground to produce ingots. The uniform properties of a single crystal promote the conductivity of electrons, thus yielding higher conversion efficiencies. We have developed manufacturing technologies that enable us to increase our yield of ingots, reduce electricity costs and enhance the utilization rate of furnaces and consumables, such as crucibles.
