“…With respect to ABSe 3 selenium‐based compounds, BaZrSe 3 was the first to be synthesized by Aslanov in 1964 . Later, Sr 1– x Ba x ZrSe 3 compounds were successfully synthesized in 1997 by Tranchitella et al using a mixture of SrSe, BaSe, Zr, and Se (with 40% and 20% molar excess of Se and Zr), in evacuated silica ampoules at high temperatures (900–950 °C) . Different crystalline structures were observed, depending on the [Ba]/([Sr] + [Ba]) ratio: NH 4 CdCl 3 type for 0 < x < 0.68 values, biphasic mixtures of NH 4 CdCl 3 and CsNiCl 3 ‐type compounds for 0.68 < x < 1.0 values, and commensurate mismatched chain compound for the Ba 1.07 ZrSe 3 having a new orthorhombic needle‐like structure.…”

Chalcogenide AB(S,Se)3 materials have recently attracted increased attention as they could simultaneously solve both the stability and toxicity issues faced by conventional perovskite solar cells. Computer‐aided design of metal chalcogenide semiconductors has experienced important progress over the past few years, leading to the discovery of very promising AB(S,Se)3 compounds and derivatives for application as absorbers in thin‐film photovoltaic devices. Experimental evidence demonstrates that the synthesis of such compounds is possible, confirming the theoretical predictions, although more research work needs to be done to further investigate the optoelectrical properties of the corresponding thin films. With the aim to provide an exhaustive starting point to further develop chalcogenide absorbers and related devices, this Review presents both an overview of the predicted chalcogenide materials and interesting derivatives for thin‐film solar cells applications, as well as a summary of the synthesis techniques developed so far to prepare such materials. The possible challenges that can be encountered during the development of chalcogenide‐based solar cells are also discussed.

“…Growth of BaZrSe 3 was first reported by Aslanov, who concluded that it crystallizes in a hexagonal structure, and that BaTiSe 3 and BaTaSe 3 were isostructural with BaZrSe 3 . [ 39 ] Later, Tranchitella et al found that BaZrSe 3 instead forms an off‐stoichiometric misfit phase, [ 74,75 ] which was also seen for SrTiSe 3 . [ 75 ] Given these findings, a GdFeO 3 ‐type perovskite structure for BaHfSe 3 , as reported in the Ph.D. thesis of Moroz, [ 111 ] seems unlikely.…”

“…ABSe 3 compounds with slightly smaller A cations, namely, SrZrSe 3 , [ 74 ] SrHfSe 3 , [ 82 ] and EuZrSe 3 , [ 94 ] were all grown in the NH 4 CdCl 3 ‐type phase. To the best of our knowledge, no phase transitions or alternative crystal structures have been reported for these compounds, in contrast to their sulfide relatives.…”

Chalcogenide perovskites have recently emerged into the spotlight as highly robust, earth abundant, and nontoxic candidates for various energy conversion applications, not least photovoltaics (PV). Now, a serious effort is required to determine if they can emulate the PV performance of the better‐known, part‐organic halide perovskites, in applications such as tandem solar cells. This review summarizes the surprisingly large body of literature pertaining to chalcogenide perovskites, which have been investigated for many years despite only recently being considered for applications. The confusing variety of claims coming from computational materials discovery is clarified, and it is specified which chalcogenide perovskites actually exist and should form the focus of experimental work. The highly interesting optoelectronic and transport properties of the known materials at their current stage of development are summarized, which makes a clear case for investigating them further. The existing synthesis literature is collated, which provides some important and possibly unnoticed clues to experimentalists grappling with these somewhat challenging materials. The authors hope that the highlighting of this information will facilitate further exciting studies, better approaches, and new progress for chalcogenide perovskites.
