“…Therefore, developing methods to control and optimize the properties of chalcohalides suitable for solar cells is imperative. Sb/Bi chalcohalides used for solar cells are prepared by many techniques including spray pyrolysis [ 40 ], spin coating [ 24 , 45 , 46 , 47 , 51 ], solvothermal synthesis [ 49 , 53 ], and mixed techniques [ 23 , 38 , 48 , 65 ]. In this section, the fabrication methods reported to date are categorized and described, with the solar cells fabricated presented by the method in Table 4 .…”

“…Using this method, nanorod-based BiSI films with an E g value of 1.61 eV were obtained ( Figure 5 f,g). Recently, Xiong et al also reported the fabrication of BiSI nanorods arrays based on a two-step method [ 49 ]. However, their method involved the solvothermal synthesis instead of spin coating in each step, as illustrated in Figure 6 a.…”

“…Following the initial application of Sb sulfoiodide (SbSI) in solar cells by the Seok group in 2018 [ 38 ], multiple Sb/Bi chalcohalide solar cells have been proposed. Thus far, the materials investigated for use in solar cells include ternary (MChX and M 13 Ch 18 X 2 , where M = Sb, Bi) [ 23 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ] and quaternary chalcohalides (

Despite their comparable performance to commercial solar systems, lead-based perovskite (Pb-perovskite) solar cells exhibit limitations including Pb toxicity and instability for industrial applications. To address these issues, two types of Pb-free materials have been proposed as alternatives to Pb-perovskite: perovskite-based and non-perovskite-based materials. In this review, we summarize the recent progress on solar cells based on antimony/bismuth (Sb/Bi) chalcohalides, representing Sb/Bi non-perovskite semiconductors containing chalcogenides and halides. Two types of ternary and quaternary chalcohalides are described, with their classification predicated on the fabrication method. We also highlight their utility as interfacial layers for improving other solar cells. This review provides clues for improving the performances of devices and design of multifunctional solar systems.

“…Some nanorod array films have been fabricated as light absorbers for new‐generation highly efficient solar cells. The light absorbers of nanorod array oriented parallelly to the carrier transporting direction can efficiently suppress optical reflection and improve light scattering and trapping [28] . Such radical junction device structure guarantees sufficient light absorption, charge generation, and carrier separation and transportation [29,30] .…”

BiSCl single‐crystalline nanofibers were synthesized by a facile one‐pot solvothermal approach for the first time. BiSCl possesses a double chain type structure and grows readily along the c‐axis, resulting the fibrous morphology. UV/Vis absorption spectroscopy revealed that BiSCl nanofibers exhibit a strong light absorption in a wavelength range from UV to visible light, corresponding to a bandgap of 1.96 eV. Ultraviolet photoelectron spectroscopy and density functional theory calculations revealed that BiSCl is a direct n‐type semiconductor with valence band maximum and conduction band minimum located at 6.04 and 4.08 eV below the vacuum level, respectively. To investigate the photovoltaic performance, the homogeneous thin film of BiSCl‐nanorod array was fabricated on a TiO2 porous film by a modified solvothermal process, where the nanorod array is oriented vertically to the surface of the TiO2 porous film. A proper band alignment of BiSCl‐based solar cells with an architecture of fluorine‐doped tin oxide (FTO)/TiO2/BiSCl/(I3−/I−)/Pt gave a PCE of 1.36 % and a relatively large short‐circuit photocurrent density of 9.87 mA cm−2 for the first time. The preliminary photovoltaic study result revealed a potential possibility of BiSCl‐nanorod array as a light absorber for solar cells that can be fabricated by the low‐cost solution process.

Inorganic–organic hybrid lead halide perovskites are emerging optoelectronic materials for solar cell application. However, the toxicity concerns and poor stability largely hamper their practical applications. For these reasons, the search for “perovskite‐inspired” alternatives, having the same advantages but overcoming the drawbacks of the lead‐based one, has become an important sector in the field. Among the candidates, Bi3+ and Sb3+ containing materials are of great interest, due to their electronic structures resembling the Pb2+. Bismuth/antimony chalcohalides have been known for a long time as the potential absorber in photovoltaics, even if their performances are still low. Interestingly, pnictogen chalcohalides can be the stepping stone toward numerous quaternary compounds, including some perovskite structures. The understanding of the fundamental properties and the current limitations of both the starting ternary compounds and the final quaternary materials can allow the achievement of improved photovoltaic absorbers, stable, and efficient. In this review, the fundamental properties and device performances of many ternary pnictogen chalcohalides and the derived quaternary compounds are summarized, focusing on the different preparation strategies.
