Session: 3CO.7 Large Area Perovskite Solar Cells and Modules
Topic: 3. 1 Perovskites
Summary / Abstract: While impressive efficiency progress has been achieved for perovskite-based solar cells, process upscaling represents one of the main remaining hurdles to commercial applications. In this contribution, the development of a scalable method to process perovskite layers in air is presented. Combining gas-quenching and optimized precursors stoichiometry, pinholesfree films were obtained via low temperature solution processing. When integrated in single junction devices, power conversion efficiency > 18% was achieved on 10 cm² modules.
