200um Polycrystalline Silicon Wafer For Solar Cell
Polysilicon wafers are usually packaged with a special protective film to avoid contamination and scratches on the surface. Packaging materials generally use materials such as plastic film and foam. During transportation, polysilicon wafers need to take professional logistics and protection measures to ensure that they are not damaged.
Description
Description
Polycrystalline silicon wafers are silicon wafers composed of many crystal grains, and the manufacturing cost of polycrystalline silicon wafers is lower than that of single crystal silicon wafers. There are grain boundaries between the crystal grains of polycrystalline silicon wafers, so the electron transfer efficiency is slightly lower than that of single crystal silicon wafers, but its energy conversion efficiency can also reach a higher level.
use:
Polycrystalline silicon wafers are mainly used in the field of solar panel manufacturing and semiconductor manufacturing. In the field of solar panel manufacturing, polycrystalline silicon wafers are one of the main materials for manufacturing ordinary solar panels. In the field of semiconductor manufacturing, polysilicon wafers are mainly used to manufacture transistors, sensors, and optoelectronic devices.
