The price of silicon material is weak and stable this week. The mainstream transaction price of single crystal compound feeding is 308 yuan/KG, and the mainstream transaction price of single crystal dense material is 305 yuan/KG. Most silicon material enterprises are in the order scheduling and delivery stage this week, with few new orders signed, and silicon material prices have not been adjusted temporarily; Although the expansion capacity is still being released, due to the impact of the epidemic and the increase of rainy and snowy weather, the inventory of silicon materials in transit has increased, the supply has lagged behind in stages, and the high price may continue. At present, the number of long-term silicon material orders signed by leading enterprises is more than that of new enterprises, and the number of silicon material bulk orders available on the market is expected to increase.
