Thin-film solar cells might offer large-scale and cheap production with highly tunable properties, e.g., semi-transparency, color, thickness, or flexibility. Slot-die coated nanocrystal and bulk hybrid perovskite thin films are significant for high-efficiency next-generation solar cell absorber materials. In this work, we show the feasibility of creating high-quality thin films of this material class by the easily scalable and roll-to-roll compatible deposition method of meniscus-guided slot-die coating. We use time-resolved grazing-incidence X-ray scattering to investigate the crystal structure, texture, and morphology of the printed thin films. We track the printing process in real-time and extract parameters describing the quality and kinetics of the printing process. We also present solar cell data with perovskite absorber layers printed from colloidal hybrid perovskite nanocrystal solution.
