The difference between monocrystalline silicon and polycrystalline silicon

Difference in appearance

The four corners of the monocrystalline silicon cell are arc-shaped and have no pattern on the surface; the monocrystalline silicon is dark blue, almost black; while the four corners of the polycrystalline silicon cell are square, with a pattern similar to ice flowers on the surface, and the polycrystalline silicon is sky blue. Bright colors.

Use the difference above

For users, there is not much difference between monocrystalline silicon batteries and polycrystalline silicon batteries, and their lifespan and stability are very good. The average conversion efficiency of monocrystalline silicon cells is higher than that of polycrystalline silicon, but the current price is also higher than that of polycrystalline silicon.

Differences in Manufacturing Processes

Polycrystalline cells have fewer production process steps than monocrystalline cells, so the energy consumed in the manufacturing process of polycrystalline silicon solar cells is slightly less than that of monocrystalline silicon solar cells, but the power generation of monocrystalline cell modules is higher. big.

Monocrystalline vs Polycrystalline

The application of monocrystalline photovoltaic panels is earlier than that of polycrystalline photovoltaic panels. The current situation is that the application of polycrystalline silicon in power stations is much higher than that of monocrystalline silicon, with monocrystalline silicon accounting for 30% and polycrystalline silicon accounting for 70%. The conversion rate, the efficiency of single crystal is higher than that of polycrystalline, about 10%-20%. The cost of single crystal is slightly more expensive than that of polycrystalline, and the cost of different manufacturers is different. At present, the cost performance of polycrystalline is slightly higher than that of monocrystalline. As the cost of monocrystalline components decreases, the price may be lower than that of polycrystalline silicon.

Silica sand is the raw material for the production of silicon wafers. LZZG’s silica sand production line and silica sand washing equipment have been used in many silica sand production factories.
