1) Demand drives the price of trichlorosilicon skyrocketing
Trichlorosilane (SiHCl3), also known as trichlorosilane, silicon chloroform, is mainly used in the production of polysilicon, silane coupling agent, the application of polysilicon for solar cells, semiconductor materials, cermet materials, optical fiber;
The applications of silane coupling agents are surface treatment, sealing plastics, sealants, adhesives and adhesives for coatings, etc.
Driven by the rapid growth of photovoltaic demand, trichlorosilicon presents a mismatch pattern between supply and demand, and its price rises sharply.
Since this year, the price of photovoltaic grade products has increased from less than 6000 yuan/ton to the current market price of about 15000-17000 yuan/ton, and the gross profit before tax of manufacturers can reach about 10000 yuan/ton.




2) The demand for photovoltaic grade trichlorosilicon grows rapidly
At present, the effective capacity of TRICHlorosilicon in China is 566,000 tons (including the part produced and used by downstream enterprises). From January to July of 2021, the output of trichlorosilicon is 205,300 tons (sales volume, excluding the part produced and used by downstream enterprises), with a year-on-year growth of 9.73% and an operating rate of about 72.5%.
But excluding the supporting downstream polysilicon and silane coupling agent of the enterprise, the actual operating rate is expected to be 90%. On. From the perspective of demand structure, the sellable photovoltaic level capacity is only about 165,000 tons, and the sellable photovoltaic level capacity under construction (technological transformation) is only about 35,000 tons.
With the rapid growth of photovoltaic demand for 21H2 downstream, the shortage pattern of photovoltaic grade trichlorosilicon is expected to be further intensified.
According to statistics, the domestic polysilicon capacity from 2020 to 2022 is 420,000 tons, 600,000 tons and 950,000 tons respectively. According to the calculation of 125GW, 170GW and 230GW installed capacity and 1:1.2 volume ratio, the corresponding polysilicon demand is 450,000 tons, 650,000 tons and 890,000 tons. The corresponding demand for photovoltaic grade TRICHlorosilicon is 230,000 tons, 330,000 tons and 440,000 tons, with a compound annual growth rate of 40%, which will greatly drive the demand for photovoltaic grade trichlorosilicon.
