Photovoltaic silicon rods, as the key raw material for solar cells, are divided into monocrystalline silicon rods and polycrystalline silicon rods, which are molded by high purity silicon melting and special processes. Monocrystalline silicon rods are prepared by the direct drawing method, while polycrystalline silicon rods are commonly used in the directional solidification method. These silicon rods are cut and processed into wafers, which are further processed into solar cell wafers and finally assembled into photovoltaic modules for photovoltaic conversion and clean energy supply. By the end of 2022, the global PV wafer production capacity will be about 664GW, of which 97.9% will be contributed by Chinese mainland enterprises. It is expected that in 2023, the production capacity of Chinese mainland manufacturers will reach 881GW, and the output will be about 622GW, with the export volume growing by more than 93.6%, highlighting China's remarkable growth and global dominance in this field.
