Industry-Compatible Fully Laminated Perovskite-CIGS Tandem Solar Cells with Co-Evaporated Perovskite.

ABSTRACT: Perovskite-CIGS thin-film tandem solar cells could potentially share vacuum-based production equipment between sub-cells, reducing CapEx and supply chain dependence while enabling flexible, lightweight designs for versatile photovoltaic applications. However, scalable vacuum-based fabrication techniques for perovskite-CIGS tandems remain limited and challenging. Here, a highly efficient and stable bilayer methylammonium lead iodide perovskite fabricated using a scalable co-evaporation technique is presented. In this bilayer structure, an additional thin layer with an enhanced PbI₂ evaporation rate is deposited atop a thick stoichiometric perovskite film. This approach reduces film roughness and improves the contact potential difference at the perovskite interface. For the first time, this
