What is the difference between mono and multicrystalline silicon cells?

Monocrystalline and multicrystalline cells are different due to their pre-production. The difference between monocrystalline and polycrystalline cells is due to the difference in their pre-production processes, which makes them different from each other in terms of appearance and electrical performance. From the appearance of: monocrystalline silicon cells four corners are rounded notched, the surface is not patterned; polycrystalline silicon cells four corners for the square corner, the surface has a pattern similar to the ice flower (the industry known as polycrystalline colorful), there is also a - a kind of suede polycrystalline silicon cell surface is not obvious ice flower-like pattern (the industry known as polycrystalline suede); monocrystalline silicon cells reflective film suede surface colour is generally presented as black blue, polycrystalline silicon cells reflective film suede surface The surface colour of the cell anti-reflective film is generally blue.

For the user, there is no significant difference between monocrystalline and polycrystalline cells with the same conversion efficiency. Both monocrystalline and polycrystalline cells have a good lifetime and stability. Although the average conversion efficiency of monocrystalline silicon cells is about 1% higher than that of polycrystalline silicon cells, monocrystalline silicon solar cells can only be made into quasi-squares (4 corners are rounded), and when forming solar modules, part of the area is not filled, whereas polycrystalline silicon solar cells are square and do not have this problem, so the conversion efficiency of solar modules is almost The conversion efficiency of solar modules is therefore almost identical. In addition, because the manufacturing process of the two solar cell materials is different, the energy consumed in the manufacturing process of polycrystalline solar cells is about 30% less than that of monocrystalline solar cells, so polycrystalline solar cells account for an increasing share of the world's total solar cell production, and the manufacturing cost will be much smaller than that of monocrystalline silicon cells, so the use of polycrystalline silicon solar cells will be more energy efficient and environmentally friendly!
