What Elements Does Polysilicon Contain?

the main component of polysilicon is the element silicon. Silicon is one of the most abundant elements in the earth's crust, it is a non-metallic element with good semiconductor properties and optical properties, so it is widely used in semiconductor materials and solar cells and other fields.

The element oxygen in polysilicon is a major impurity element. Oxygen can exist in polysilicon in the form of oxides, which affect the electrical and optical properties of silicon materials.

Polysilicon also contains a small amount of carbon. Carbon can exist in the form of carbide in polysilicon, it will have a certain impact on the lattice structure and electrical properties of silicon materials.

polysilicon also contains trace amounts of nitrogen. Nitrogen can exist in the form of nitride in polysilicon, it will affect the electrical conductivity and thermal properties of silicon materials.

polysilicon also contains trace amounts of phosphorus. Phosphorus can be in the form of phosphide in polysilicon, which affects the electrical conductivity and optical properties of silicon materials.

polysilicon also contains a small amount of molybdenum. Molybdenum can exist in the form of molybdenum compounds in polysilicon, it will have a certain impact on the electrical conductivity and thermal properties of silicon materials.

In addition to the above elements, polysilicon may also contain other trace amounts of impurity elements, which will have a certain impact on the performance of polysilicon. Therefore, in the production of polysilicon materials, the raw materials need to be finely controlled and processed to ensure the high purity and stability of polysilicon materials.
