Instruction of Polycrystalline Silicon Solar Cells/Solar Panels
2022-08-18
The production 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. In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the material is simple to manufacture, power consumption is saved, and the total production cost is lower, so it has been greatly developed. In addition, the service life of polycrystalline silicon solar cells is also shorter than that of monocrystalline silicon solar cells.
The production of polycrystalline silicon solar cells needs to consume a large amount of high-purity silicon materials, and the manufacturing process of these materials is complicated and the power consumption is very large, which accounts for more than half of the total production cost of solar cells. In addition, the drawn monocrystalline silicon rod is cylindrical, and the solar cell made by slicing is also a wafer, and the plane utilization rate of the solar module is low. Therefore, since the 1980s, some European and American countries have invested in the development of polycrystalline silicon solar cells. 18v solar panel,320 watt solar panel price,335 watt solar panel
