Polycrystalline Silicon 553
Polycrystalline Silicon is a silicon crystal made by the reaction of polysilicon powder, hydrogen and argon gas and other gas mixtures. The grain size of polycrystalline silicon is much larger than that of monocrystalline silicon, and the crystal structure is irregular with more grain boundaries, and the electrical properties are not as good as those of monocrystalline silicon.

Description
Polycrystalline Silicon is produced on a large scale and has a short production cycle. Monocrystalline silicon production scale and production cycle are much worse than polycrystalline silicon, which is one of the reasons why polycrystalline silicon is more competitive in the market.
Polycrystalline Silicon is low. Polysilicon grain structure is not identical, electrons, hole life and diffusion length is not exactly the same, resulting in a small short-circuit current, improve photoelectric conversion efficiency.
The size of Polycrystalline Silicon is large. Compared to monocrystalline silicon, polycrystalline silicon has a larger grain size, so it is more tolerant of defects in the wafer during preparation and easier to manufacture
