Lamination and recrystallization of perovskite thin films for photovoltaics

This work presents lamination as an innovative fabrication process for perovskite-based photovoltaics (PVs). Solar cells are processed in two independent half-stacks, subsequently united by hot-pressing. This method enables new choices for materials, deposition techniques, and architectures. Lamination thereby offer the necessary fabrication flexibility to address the remaining milestones of perovskite PVs – scalability, stability, and efficiency –, paving the way toward commercialization.
