Market context
Polysilicon, semiconductors and data centres
Processor chips depend on a precise industrial chain: high-purity silicon, crystal growth and wafers, followed by semiconductor fabrication. Expanding computing and AI bring attention to the materials and infrastructure behind that chain. Data centres use finished chips, not raw polysilicon.
From silicon to the computing era

Different markets. Different requirements.
Solar-grade material is not automatically interchangeable with electronic grade. WACKER’s 2025 results reported very strong performance for hyperpure semiconductor polysilicon alongside lower solar-grade sales volumes. AI growth does not establish a shortage across all polysilicon grades or qualify a particular plant to supply advanced chips.
Power and technical qualification
The IEA’s 2025 Energy and AI report projects data-centre electricity use more than doubling by 2030 in its base case. This informs energy-infrastructure analysis, rather than directly forecasting polysilicon demand. Evaluating the offered asset requires product-purity data, impurity controls, operating records, energy costs and customer qualification requirements before defining its target application.
