Properties
Germanium is a brittle, silvery-white semimetal. It has the same cubic crystal structure as diamond.
Germanium is a semiconductor. It has a high refractive index and is high transparency to infrared radiation.
CNGE has already been able to produce 1-8 inch germanium wafer for solar cells with CZ Czochralski “zero dislocation” technology. The products are widely used in solar space cells. The company is now a leading domestic manufacturer of this product. CNGE currently has a class 5 of ISO14644-1 dust-free workshop production line which now can produce 1800 thousand solar germanium wafer annually.
Application
Used in solar space cells.
