Characteristics of PolySilicon Technology
First: Difference in appearance Technical features of polysilicon From the appearance, the four corners of the monocrystalline silicon cell are arc-shaped, and there are no patterns on the surface; while the four corners of the polysilicon cell are square corners, and the surface has patterns sim...Read more -
The main uses of polysilicon
polysilicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooling conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these crystal nuclei grow into grains with different crystal plane orientations, these gra...Read more -
What are the raw materials for producing polysilicon?
The raw materials for producing polysilicon mainly include silicon ore, hydrochloric acid, metallurgical grade industrial silicon, hydrogen, hydrogen chloride, industrial silicon powder, carbon and quartz ore. Silicon ore: mainly silicon dioxide (SiO2), which can be extracted from sili...Read more -

Method for preparing polysilicon.
1. Loading Place the coated quartz crucible on the heat exchange table, add silicon raw material, then install heating equipment, insulation equipment and furnace cover, evacuate the furnace to reduce the pressure in the furnace to 0.05-0.1mbar and maintain vacuum. Introduce argon as a pro...Read more -
What is polysilicon？
polysilicon is a form of elemental silicon, which is a semiconductor material composed of multiple small crystals spliced together. When polysilicon solidifies under supercooling conditions, silicon atoms arrange in a diamond lattice form into many crystal nuclei. If these nuclei grow into grains...Read more -
