Introduction to the Photovoltaic Industry Chain

● The growth of photovoltaic grade silicon single crystals is carried out in a crystal growth furnace at 1500 ℃, and thermal field components such as heaters are made of graphite. The insulation of the thermal field is achieved by carbon fiber insulation materials.

● Polycrystalline casting is prepared by directional solidification method, and the heater consists of side heaters, top and bottom heaters. The insulation is also achieved by carbon fiber insulation material.
