These particles combine and crystallize into polysilicon. Utilization value: From the development history of international solar cells, it can be seen that its development trend is monocrystalline silicon, polycrystalline silicon, ribbon silicon and thin film materials (including microcrystalline silicon-based films, compound-based films and dye films).
The counterweight electric heater is actually a convection electric heater, and the body of this electric heater can be designed very thin. The hot air generated by heating elements such as silicon crystal plate convection the indoor cold air, which makes the whole indoor air temperature rise and reach a warm state.
Extended data:
Polycrystalline silicon can be used as raw material for drawing monocrystalline silicon, and the difference between polycrystalline silicon and monocrystalline silicon is mainly manifested in physical properties. For example, the anisotropy of mechanical properties, optical properties and thermal properties is far less obvious than that of monocrystalline silicon; In electrical properties, the conductivity of polycrystalline silicon crystal is far less significant than that of monocrystalline silicon, or even almost no conductivity.
In terms of chemical activity, there is little difference between them. Polysilicon and monocrystalline silicon can be distinguished in appearance, but the real identification must be determined by analyzing the crystal plane direction, conductivity type and resistivity. Polycrystalline silicon is the direct raw material for producing monocrystalline silicon, and it is also the basic electronic information material for contemporary semiconductor devices such as artificial intelligence, automatic control, information processing and photoelectric conversion.
