The European Technology and Innovation Platform Photovoltaics (ETIP PV) is a continuation of the European PV Technology Platform (EU PVTP) and the Solar European Industry Initiative (SEII) in a single platform under the new SET Plan governance. The ETIP PV’s mission is in line with the Energy Union and the SET Plan priorities with focus on “Renewable technologies at the heart of the new energy system” and Europe to become “number 1 in renewables”.

Current single‐junction crystalline silicon (c‐Si) solar cells are approaching their power conversion efficiency (PCE) limit. Tandem solar cells are expected to overcome such efficiency limit, with perovskite on c‐Si tandems being a promising candidate for commercialization over the next years. This work aims atdescribing the conditions that tandem cells and modules need to fulfill to successfully enter the market in 2030. We first estimate that industrial c‐Si photovoltaic modules may reach a price level of
