To prevent the worst outcomes of climate change and increase Europe’s energy independence, urgent and massive efforts are requiredto transform Europe’s energy production to renewable and secure sources. Photovoltaics (PV) has emerged as a key technology in theseefforts with projected annual growth rates of 30-35% over the next years. A strong base of PV industry across the entire value chainis, therefore, of strategic importance for Europe to support this strong market growth. Since the currently dominating silicon (Si) PVtechnology is approaching its efficiency limit, PEPPERONI aims to 'spice up' cost-efficient industrial Si cells with a thin perovskite topcell in a monolithic tandem device. This technology promises the best ratio of performance over manufacturing costs and therefore enablesto push solar module efficiencies beyond the limit of Si at lowest CO2 footprint. The key objective of PEPPERONI is to enable largescaleproduction of such tandem PV modules in Europe by (i) demonstrating 26%-efficient modules on industrial scale; (ii) developingfabrication processes for high-volume manufacturing; (iii) extending the operational stability of tandems to meet market expectations(>30 yr); and (iv) removing any human health or environmental risk. To reach these objectives, PEPPERONI capitalises on the worldleadingtandem PV expertise of a strong and complementary consortium: 4 equipment suppliers, 2 material suppliers, 1 service provider,9 R&D institutes and universities that hold tandem efficiency world records, and one of the world's largest PV module manufacturers:PEPPERONI coordinator Q CELLS. When joining forces, their excellence puts PEPPERONI in the unique position to set up a tandempilot line in Europe by 2026. This will establish a robust and competitive European innovation base and PV supply chain, putting allinvolved partners well on track towards GW-scale production of solar modules in Europe by 2030.
