Chalcogenide perovskites, ABX₃ crystal structure with X=S, Se or Te, are emerging light absorber as an alternative to toxic and unstable halide perovskites. Despite their promising properties, the absence of lowtemperature solution processing poses a major obstacle for chalcogenide perovskite-based optoelectronic devices. In this review, we survey various synthetic techniques for chalcogenide perovskites, focusing on BaZrS3 composition. Research progress in non-solution processing methods, such as solid-state reaction and pulsed laser deposition, is briefly covered and recent reports about low-temperature solution processing for chalcogenide perovskite are highlighted. Future research perspective toward realizing chalcogenidebased optoelectronic device based on solution processing is provided. We believe this timely review will facilitate the discovery of novel solution processing for chalcogenide perovskites, the challenging materials with tantalizing prospects.
