Metal halide perovskite solar cells (PSCs) have gained significant attention in thin-film photovoltaic research for their high power conversion efficiency (PCE) and facile fabrication processes. This study presents the use of inkjet printing to fabricate thin films combinatorial mixed formamidinium tin-lead perovskites evaluates layer quality device performance. Our findings demonstrate that incorporating Pb up 50% into FASnI3 enhances lattice stability. The investigation focused on optimizing composition ratio improved performance with FASn0.5Pb0.5I3-based PSCs achieving highest PCE 10.26%. Additionally, these exhibited an absorption spectrum extending beyond 1000 nm, corresponding a 1.25 eV bandgap. results suggest can effectively enhance tin–lead-based PSCs, supporting scalability manufacturing.
