Abstract
Analysis of the Electricity Consumption for the Production of Electronic-Grade Polysilicon (Fraunhofer ISE, on behalf of Wacker Chemie AG). Fetched by the auto-model research pass; the figures below are cited from this source in the model's flow, idiot-index, energetic-index, and market tabs.
Key facts
- Solar-grade (SoG) polysilicon specific electricity consumption 60-71 kWh/kg (2023, CPIA and Fraunhofer ISE data)
- Electronic-grade (EG) polysilicon electricity consumption estimated at ~92-124 kWh/kg for 2025
- EG is 32-53 kWh/kg higher than SoG
- CVD reactor: EG rod growth at ~1 mm/h needs ~66 kWh/kg vs ~35 kWh/kg at 1.9 mm/h for SoG; CVD step ~31 kWh/kg higher for EG
