​Because of the difference of the pre-production process between monocrystalline silicon and polycrystalline silicon, there are some differences in their appearance and electrical performance.

Because of the difference of the pre-production process between monocrystalline silicon and polycrystalline silicon, there are some differences in their appearance and electrical performance. The four corners of the monocrystalline silicon solar cells are circular, and the surface of the monocrystalline silicon solar cells has no pattern. The four corners of the polycrystalline silicon solar cells are square, and the surface of the monocrystalline silicon solar cells has ice-like pattern.

For users, there is no big difference between monocrystalline and polycrystalline silicon solar cells. The life and stability of monocrystalline and polycrystalline silicon solar cells are very good. Although the average conversion efficiency of monocrystalline silicon solar cells is about 1% higher than that of polycrystalline silicon cells, because monocrystalline silicon solar cells can only be made into quasi-square (its four corners are circular arcs), when they are composed of solar cell components, a part of the area is unsatisfactory, while polycrystalline silicon solar cells are square, there is no such problem, so sub-solar cell components. The efficiency is almost the same. In addition, polycrystalline silicon solar cells consume less energy than monocrystalline silicon solar cells because of the different manufacturing processes of the two kinds of solar cell materials. Therefore, polycrystalline silicon solar cells account for a large share of global solar cell production and cost less than monocrystalline silicon solar cells. Therefore, the use of polycrystalline silicon solar cells will be more energy-saving and more environmentally friendly.
