Poly Crystalline Silicon Wafers For Solar Cell

Polycrystalline silicon wafers are a lower cost solar cell material compared to monocrystalline silicon wafers. The following is an introduction to the different aspects of polysilicon wafers:

The crystalline form of polycrystalline silicon wafers is irregular, so there are certain differences in their lattice constants and impurity distributions. This makes polycrystalline silicon wafers have poor electrical performance, but also makes polycrystalline silicon wafers have better light absorption capabilities, so they are widely used in solar cells.

Since the production process of polycrystalline silicon wafers is relatively simple, its cost is relatively low, about half of that of monocrystalline silicon wafers.
