Silicon Ingot
We have the best production technology for ingot that may be used for high-efficient wafer manufacturing.
Silicon ingot is produced by melting and reforming the polysilicon, which is the main material for solar energy technology, into a rectangular form. This is used in sliced forms to be produced into wafers for the use in solar energy technology.
