Main properties and value of polysilicon

Property
Polysilicon is a very important semiconductor material because of its semiconductor properties, but a small amount of impurity can greatly affect its conductivity. It is widely used in the electronic industry to manufacture semiconductor radio, tape recorder and refrigerator. Basic materials for color TV, video recorders, electronic computers, etc. Chlorinated by dry silica powder and dry hydrogen chloride under certain conditions, then condensed and rectified. Jiangxi eutectic photovoltaic technology co., Ltd photovoltaic eutectic photovoltaic technology co., Ltd. Polysilicon can be used as the raw material for drawing monocrystalline silicon. The difference between polysilicon and monocrystalline silicon is mainly in physical properties, for example, the anisotropy of mechanical, optical and thermal properties is much less obvious than that of monocrystalline silicon. In terms of electrical properties, the electrical conductivity of polycrystalline silicon crystal is much less than that of monocrystalline silicon, even almost no conductivity. The difference between the two is very small. Polysilicon and monocrystalline silicon can be distinguished from each other in appearance, but the real identification must be made by analyzing and determining the orientation of crystal plane. Polysilicon is the direct raw material of monocrystalline silicon, which is the modern artificial intelligence, automatic control, information processing. Basic electronic information materials for semiconductor devices such as photovoltaic conversion. Known as the "cornerstone of the microelectronics building".

Value
In solar energy utilization, monocrystalline silicon and polysilicon also play a great role. Although at present, to make solar power generation have a large market, by the majority of consumers. It is necessary to improve the photoelectric conversion efficiency of solar cells and reduce the production cost. From the current international solar cell development process can be seen that its development trend is monocrystalline silicon, polycrystalline silicon, ribbon silicon. Thin film materials (including microcrystalline silicon based films). Compound based film and dye film). Jiangxi eutectic photovoltaic technology co., Ltd.
