“…The poor film morphology results in a reduction in the fill factor (FF) of the PSCs, which ultimately gives rise to an underperforming PCE. Lastly, with eco-friendly element compositions, chalcogenide PVK-based solar cells are promising candidates with their high resistance to water and temperature [243]. In 2016, BaZr 0.75 Ti 0.25 S 3 , reported by Meng and his teams, had a bandgap of 1.43 eV that almost reached the Shockley-Queisser limit [244].…”

Perovskite solar cells represent one of the most promising emerging photovoltaic technologies due to their high power conversion efficiency. However, despite of the huge progress made not only in terms of the efficiency achieved, but also fundamental understanding of relevant physics of the devices and issues which affect their efficiency and stability, there are still unresolved problems and obstacles on the path towards commercialization of this promising technology. In this roadmap, we aim to provide a concise and up to date summary of outstanding issues and challenges, and progress made towards addressing these issues. While the format of this article is not meant to be a comprehensive review of the topic, it provides a collection of the viewpoints of the experts in the field which covers a broad range of topics related to perovskite solar cell commercialization, including those relevant for manufacturing (scaling up, different types of devices), operation and stability (various factors), and environmental issues (in particular the use of lead). We hope that the article will provide a useful resource for researchers in the field and that it will facilitate discussions and moving forward towards addressing the outstanding challenges in this fast developing field.

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.

“…17 However, sulfide perovskites are synthesized at high temperatures (800−1000 °C), and the study of their charge transport is in the early stages. 18 An obvious obstacle to introducing S 2− into halide perovskites is charge balance. We therefore considered organosulfides (RS − ) as more suitable ligands to replace halides.…”

Although sulfide perovskites usually require high-temperature syntheses, we demonstrate that organosulfides can be used in the milder syntheses of halide perovskites. The zwitterionic organosulfide, cysteamine (CYS; +NH3(CH2)2S–), serves as both the X– site and A+ site in the ABX3 halide perovskites, yielding the first examples of 3D organosulfide-halide perovskites: (CYS)PbX2 (X– = Cl– or Br–). Notably, the band structures of (CYS)PbX2 capture the direct bandgaps and dispersive bands of APbX3 perovskites. The sulfur orbitals compose the top of the valence band in (CYS)PbX2, affording unusually small direct bandgaps of 2.31 and 2.16 eV for X– = Cl– and Br–, respectively, falling in the ideal range for the top absorber in a perovskite-based tandem solar cell. Measurements of the carrier dynamics in (CYS)PbCl2 suggest carrier trapping due to defects or lattice distortions. The highly desirable bandgaps, band dispersion, and improved stability of the organosulfide perovskites demonstrated here motivate the continued expansion and exploration of this new family of materials, particularly with respect to extracting photocurrent. Our strategy of combining the A+ and X– sites with zwitterions may offer more members in this family of mixed-anion 3D hybrid perovskites.
