Solar cell is the main core component of photovoltaic power generation. Its material is mainly crystalline silicon. Compared with polycrystalline silicon, monocrystalline silicon has the characteristics of lower defects and stronger mechanical strength, and the conversion efficiency of monocrystalline silicon solar cells is about 2% higher than that of polycrystalline silicon. And with the introduction of diamond wire cutting technology in 2015 and the subsequent development of new solar cell technologies such as PERC, TopCon, and HIT, the manufacturing cost of monocrystalline silicon cells has dropped rapidly and the conversion efficiency has increased significantly. In recent years, the market share of monocrystalline silicon has been rapid rising
