Through resource integration and technological innovation, based on production specialization, we carry out business diversification;
Win-Win: Win-win with customers, win-win with employees, win-win with shareholders
Monocrystalline silicon is a crystal with a basically complete lattice structure. It has different properties in different directions and is a good semiconductor material. Monocrystalline silicon rods are grown from the melt using the Czochralski method or the floating zone method in industrial production. The main indicators include minority carrier lifetime, oxygen content, etc. Monocrystalline silicon rods are the raw material for producing monocrystalline silicon wafers. [Learn more]

Solar cells are currently the fastest-developing type of solar energy cells. Their structure and production processes have been standardized, and the products are widely used in both space and terrestrial applications. These solar cells use high-purity monocrystalline silicon rods as raw materials. To reduce production costs, solar cells for terrestrial applications now use solar-grade monocrystalline silicon rods, with somewhat relaxed material performance indicators. Some may also use head and tail materials and waste monocrystalline silicon materials from semiconductor device processing, which are re-pulled into monocrystalline silicon rods specifically for solar cells.
