摘要
Abstract Development of industrially relevant thin‐film deposition processes is a necessity for upscaling the perovskite solar cell technology to commercial product‐level. This work reports on a sequential deposition method for state‐of‐the art triple cation perovskite by slot‐die coating. During this two‐step process, first, a layer of lead iodide mixed with cesium iodide is deposited, followed by applying the organic cations on top, inducing conversion to perovskite during a second slot‐die coating step. By carefully tuning the ink composition and the deposition parameters, uniform perovskite layers of 5 × 10 cm 2 are obtained. Power conversion efficiencies up to 19% for small laboratory solar cells adopting a planar device configuration and up to 15.2% for mini‐modules with an aperture area of 12 cm 2 are presented. These values are among the highest efficiencies achieved in the literature for slot‐die‐coated perovskite.
