ALTERNATIVE PROCESSES AND EQUIPMENT FOR ADVANCED MANUFACTURING OF PV TECHNOLOGIES TO BOOST THE EUROPEAN ENERGY INDEPENDENCE

ongoing

The EMPOWER project will develop alternative equipment and processes to advance PV manufacturing, tackling the bottlenecks across the entire value chain-from Si wafer production to PV module fabrication-. Our goal is to reduce Capital Expenditure (CapEx) and Operating Expenditure (OpEx), leading to a lower Levelized Cost of Electricity (LCOE) in Europe. We aim to enhance throughput, yield, sustainability, and decrease energy and raw material consumption. We will demonstrate the high-quality N-type Si wafers production using direct wafering tools, bypassing the traditional PolySi, ingot, and sawing process, contributing to cost reduction, minimizing waste production CO2 footprint. This innovative wafering technology will revolutionize the traditional wafer process, revitalizing Europe's PV upstream industry. Simultaneously, we will demonstrate alternative metallization processes for solar cells to reduce silver (Ag) consumption, high-throughput edge passivation to mitigate power loss during cell cutting, and high-speed interconnection and lamination to meet flexibility requirements in diverse cell and module configurations. The emphasis is on advancing N-type Si-based high-efficiency solar cell technologies, prioritizing low carbon footprint production, with an opportunity to compete with the Chinese PV industry. Leveraging Industry 4.0 implementation, EMPOWER aims to enhance production efficiency, improve PV production quality, and further reduce production costs. The project includes a demonstration of a virtual vertically integrated PV production line, along with the development of business cases and market introduction strategies. Through close collaboration in a multidisciplinary and multiactor approach including a solid exploitation and business development strategy, EMPOWER will not only achieve low-cost European PV manufacturing, but also bring Europe back to the leadership in the PV sector.
