We commenced production of multicrystalline ingots in May 2006. To produce multicrystalline ingots, the molten polysilicon is changed into a block through a casting process in the multicrystalline furnaces. Crystallization starts by gradually cooling the crucibles in order to create multicrystalline ingot blocks. The resulting ingot blocks consist of multiple smaller crystals as opposed to the single crystal of a monocrystalline ingot. The output of a multicrystalline furnace is higher than that of a monocrystalline furnace. 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.
