Polysilicon Prices September 2025

Market Overview Q3 Ending September 2025

Northeast Asia: In Northeast Asia, polysilicon prices rose sharply as robust solar photovoltaic demand drove procurement from wafer and cell manufacturers. The polysilicon price index reflected stronger downstream activity, supported by government-backed renewable energy projects. While feedstock availability was steady, higher utilization rates among producers pushed values upward. Regional export flows also tightened, adding momentum to price increases across the quarter.

Europe: In Europe, polysilicon prices surged as local demand from solar panel producers combined with limited import availability to create a supply-demand imbalance. The polysilicon price index strengthened significantly, driven by policy support for clean energy expansion and a strong pipeline of solar installations. Higher energy costs and constrained supply chains added to upward pricing momentum, with buyers securing volumes at premium levels to avoid disruptions.

North America: In North America, polysilicon prices climbed moderately as downstream demand from solar energy developers improved. The polysilicon price index showed firmer procurement levels, supported by growing investment in domestic solar manufacturing capacity. While imports helped balance availability, strong renewable energy commitments and stable feedstock costs allowed regional producers to secure higher prices, albeit at a slower pace compared to Europe and Asia.

Product Description

Polysilicon is a highly purified form of silicon produced through chemical vapor deposition of trichlorosilane or silane gas. It is characterized by its crystalline structure, high purity (often exceeding 99.9999%), and excellent semiconductor properties. Polysilicon is primarily used in the production of solar photovoltaic cells, where it serves as the base material for wafers and ingots. It is also critical in the electronics industry for manufacturing semiconductors and integrated circuits. The material exhibits thermal stability, electrical conductivity, and strong resistance to chemical degradation. As the demand for renewable energy grows, polysilicon’s role in solar power generation continues to expand, while its applications in high-tech electronics reinforce its strategic importance in global industries.
