“…BiI3 also demonstrates rather large absorption coefficients in visible region on the order of 105-106 cm-1 [248]. However, SbI3 single crystals were found to have an Urbach energy over 200 meV at room temperature [248], indicating that several defect states may exist within the band gap.…”

Lead-halide perovskites have demonstrated astonishing increases in power conversion efficiency in photovoltaics over the last decade. The most efficient perovskite devices now outperform industry-standard multi-crystalline silicon solar cells, despite the fact that perovskites are typically grown at low temperature using simple solution-based methods. However, the toxicity of lead and its ready solubility in water are concerns for widespread implementation. These challenges, alongside the many successes of the perovskites, have motivated significant efforts across multiple disciplines to find lead-free and stable alternatives which could mimic the ability of the perovskites to achieve high performance with low temperature, facile fabrication methods. This Review discusses the computational and experimental approaches that have been taken to discover lead-free perovskite-inspired materials, and the recent successes and challenges in synthesizing these compounds. The atomistic origins of the extraordinary performance exhibited by lead-halide perovskites in photovoltaic devices is discussed, alongside the key challenges in engineering such high-performance in alternative, next-generation materials. Beyond photovoltaics, this Review discusses the impact perovskite-inspired materials have had in spurring efforts to apply new materials in other optoelectronic applications, namely light-emitting diodes, photocatalysts, radiation detectors, thin film transistors and memristors. Finally, the prospects and key challenges faced by the field in advancing the development of perovskite-inspired materials towards realization in commercial devices is discussed.

In this paper a novel method of SbSI single crystals fabrication is presented. In this method a sonochemically prepared SbSI gel is used as an intermediate product in a vapour growth process. The main advantages of the presented technique are as follows. First, the SbSI gel source material has lower temperature of sublimation and allows to avoid explosions during SbSI synthesis (the sonochemical synthesis is free of any explosion hazard). Second, but not least, the grown SbSI single crystals have smaller ratio of longitudinal and lateral dimensions. The cross sections of the presented crystals are relatively large (they are up to 9 mm 2 ). The crystals have been characterized by X-ray diffraction, angle-resolved optical spectroscopy, and diffusive reflectivity.

“…The VA group metal triiodides MI 3 (M = Sb and Bi), a class of novel two-dimensional (2D) compounds, have attracted much interest owing to their unique physicochemical properties and versatile applications. 1,2 A distinctive member in MI 3 materials, SbI 3 possesses excellent optical and electrical properties, and thus emerges as a promising candidate for solid-state batteries, radiation detectors, and photocatalysts. [2][3][4][5][6] SbI 3 forms a quasimolecular layered crystal, where each layer is constituted by an I-Sb-I sandwich via strong covalent-ionic bonds, and the adjacent layers are piled up along the c-axis direction by weak van der Waals interactions.…”
