“…We recently reported the synthesis of BaZrS 3 nanoparticles at 330 °C, 20 with similar results reported by Zilevu at al. 21 Such nanoparticles are yet to be processed into device-grade films. Turnley et al 22 reported the solution-based synthesis of BaZrS 3 via sulfurization of an organometallic Ba precursor and ZrH 2 at temperatures above 550 °C; however, continuous, dense films were not possible in this approach.…”

Chalcogenide perovskites have attracted increasing research attention in recent years due to their promise of unique optoelectronic properties combined with stability. However, the synthesis and processing of these materials has been constrained by the need for high temperatures and/or long reaction times. In this work, we address the open question of a low-temperature growth mechanism for BaZrS 3 . Ultimately, a liquid-assisted growth mechanism for BaZrS 3 using molten BaS 3 as a flux is demonstrated at temperatures ≥540 °C in as little as 5 min. The role of Zrprecursor reactivity and S (g.) on the growth mechanism and the formation of Ba 3 Zr 2 S 7 is discussed, in addition to the purification of resulting products using a straightforward H 2 O wash. The extension of this growth mechanism to other Ba-based chalcogenides is shown, including BaHfS 3 , BaNbS 3 , and BaTiS 3 . In addition, an alternative vapor-transport growth mechanism is presented using S 2 Cl 2 for the growth of BaZrS 3 at temperatures as low as 500 °C in at least 3 h. These results demonstrate the feasibility of scalable processing for the formation of chalcogenide perovskite thin-films.

“…[14,15] Nanoparticles of BaZrS 3 have also been synthesized at temperatures less than 350 °C, providing evidence that these materials can be solution-processed. [16,17] But it remains to be seen if these nanoparticles can be processed into large-grain thin films. Our group recently developed a direct-tofilm solution-processed route for BaMS 3 (M = Ti, Zr, Hf ) materials that utilizes heat treatment in a sulfur-containing atmosphere at modest temperatures from 500 to 575 °C.…”

Chalcogenide perovskites are promising semiconductor materials with attractive optoelectronic properties and appreciable stability, making them enticing candidates for photovoltaics and related electronic applications. Traditional synthesis methods for these materials have long suffered from high‐temperature requirements of 800–1000 °C. However, the recently developed solution processing route provides a way to circumvent this. By utilizing barium thiolate and ZrH2, this method is capable of synthesizing BaZrS3 perovskite at modest temperatures (500–600 °C), generating crystalline domains on the order of hundreds of nanometers in size. Herein, a systematic study of this solution processing route is done to gain a mechanistic understanding of the process and to supplement the development of device quality fabrication methodologies. A barium polysulfide liquid flux is identified as playing a key role in the rapid synthesis of large‐grain BaZrS3 perovskite at modest temperatures. Additionally, this mechanism is successfully extended to the related BaHfS3 perovskite. The reported findings identify viable precursors, key temperature regimes, and reaction conditions that are likely to enable the large‐grain chalcogenide perovskite growth, essential toward the formation of device‐quality thin films.

Chalcogenide perovskites, ABX<sub>3</sub> 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 low-temperature 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 BaZrS<sub>3</sub> 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 chalcogenide-based 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.
