ALTERNATIVE SILICON WAFER GROWTH TECHNOLOGY FOR LOW-COST HIGH-EFFICIENCY PHOTOVOLTAICS

Objective

ALLEGRO aims to establish a competitive and resilient European silicon wafer manufacturing ecosystem by developing and demonstrating a disruptive kerfless wafer technology based on epitaxial growth from the gas phase. This innovative approach eliminates the energy- and material-intensive steps of conventional wafer production, significantly reducing costs, carbon footprint, and reliance on imports. ALLEGRO will demonstrate wafer manufacturing, including equipment, advanced inline inspection, and AI-driven process control capable of gigawatt-scale production of high-quality EpiWafers. While the consortium includes international expertise, ALLEGRO is designed to rely primarily on a European supply chain for key equipment and infrastructure, reinforcing strategic autonomy and industrial resilience. The project directly supports the goals of the Net-Zero Industry Act, REPowerEU, and the European Solar PV Industry Alliance.
