Lead-halide perovskites have attracted significant attention due to their favorable optoelectronic properties, simple processing, and the availability of precursor materials. Their performance is strongly governed by the crystallinity and morphology of the typically polycrystalline thin films. Among strategies to optimize these features, nanocrystal seeding has emerged as a promising route. Here, we show improved crystallographic orientation and reduced defect density in printed FAPbI3 thin films through the introduction of CsPbI3 nanocrystal nucleation seeds. Incidence-angle-varied GIWAXS enabled depth-resolved structural analysis, revealing seed incorporation and corresponding modifications of the energy landscape through the film thickness.
