What is the difference between monocrystalline silicon solar cells and polycrystalline silicon solar cells?

Solar cells are divided into monocrystalline silicon and polycrystalline silicon. What are the differences between them?


Monocrystalline silicon solar cells have high photoelectric conversion efficiency.


Monocrystalline solar panel is an assembly of several monocrystalline silicon solar cells assembled on one panel in a certain way. The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%, which is the highest among all kinds of solar cells.


The cost of monocrystalline silicon solar panels is high.


The cost of monocrystalline silicon solar panel is so high that it can not be widely used. As the single crystal silicon is generally packaged with toughened glass and waterproof resin, it is strong and durable.


Longer service life of monocrystalline silicon solar panels


The service life of monocrystalline silicon solar cells is generally up to 15 years, and up to 25 years. It is mainly used in the production of high quality solar lamps.


What are the characteristics of polysilicon solar cells?


The fabrication process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower, and its photoelectric conversion efficiency is about 12%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells. The materials are easy to manufacture and save power consumption. The total production cost is lower, so it has been developed in a large number. In addition, the service life of polysilicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of performance price ratio, monocrystalline silicon solar cells are slightly better.
