Abstract Chalcogenide perovskites have garnered increasing attention as stable, non‐toxic alternatives to lead halide perovskites. However, their conventional synthesis at high temperatures (>1000 °C) has hindered widespread adoption. Recent studies developed low‐to‐moderate temperature methods (<600 using reactive precursors, yet a comprehensive understanding of the pivotal factors affecting reproducibility and repeatability remains elusive. This study delineates critical in low‐temperature BaMS 3 (M═Zr, Hf, Ti) compounds presents generalized framework. Innovative approaches are for synthesizing this framework involving organometallics solution deposition. The molecular precursor routes, employing metal acetylacetonates generate soluble metal–sulfur bonded complexes metal–organic produce metal‐thiolate, metal‐isothiocyanate, metal‐trithiocarbonate species, demonstrated yield carbon‐free . These achieved most contiguous films BaZrS BaHfS deposition date. Furthermore, hybrid processing method stacking sputter‐deposited Zr solution‐deposited BaS layers is employed synthesize contiguous, oxygen‐free film. diffuse reflectance measurements indicate direct bandgap ≈ 1.85 eV 2.1 film under investigation.
