3, market structure
Compared with polycrystalline silicon wafers, single crystal silicon wafers have better performance, higher power generation under the same conditions, less power attenuation during long-term use, and stronger weak light response. Especially after the revolution in diamond wire cutting technology, the gap in production costs of single polycrystalline silicon wafers has greatly narrowed, making it have obvious competitive advantages over polycrystalline silicon wafers, which has led to the penetration rate of single crystal silicon wafers and . According to data, by 2021, the proportion of monocrystalline silicon wafers (N-type + P-type) in my country has increased to 94.5%, and the proportion of polycrystalline silicon wafers has decreased to 5.2%.

4, export situation
From the perspective of export situation, before 2020, my country's photovoltaic silicon wafer export volume showed a downward trend overall, mainly because the domestic photovoltaic silicon wafer market has been in a state of supply and demand imbalance for a long time. As domestic production capacity continues to expand, the downward trend of export volume continues to slow down. By 2021, my country's photovoltaic silicon wafer exports will reach US$2.45 billion, an increase of 38.4% year-on-year.
