Finished Polysilicon

Yichang CSG has adopted the improved SIEMENS method, that is to say, based on the original SIEMENS process, it adds a dry recovery system for the reduction of tail gas, and SiCl4 hydrogenation process, achieving the close-loop circle. This method reduces product’s unit energy consumption by using large-scale reduction furnace, thus decreases material consumption.
Poly-crystalline silicon is the main material of semiconductor and solar energy cell to produce molectron, discrete device and solar cell. With the rapid development of PV industry, for poly-crystalline silicon, the demand from solar energy cell is more than that from semiconductor. Solar energy is an affluent and environmentally friendly renewable resource, and its development is greatly supported by every country.
