Solar cell is the main core component of photovoltaic power generation, its material is mainly crystalline silicon, compared with polysilicon monocrystalline silicon has the characteristics of lower defects, stronger mechanical strength, and monocrystalline silicon solar cell conversion efficiency is about 2% higher than polysilicon, with the introduction of diamond wire cutting technology and perC, TopCon, HIT and other new solar cell technology development, monocrystalline silicon battery manufacturing costs and conversion efficiency increased significantly, in recent years, single silicon market share has risen rapidly.
