Prospect for Bismuth/Antimony Chalcohalides‐Based Solar Cells

Jizhou He,
Xiaodong Hu,
Zonghao Liu
et al.

Abstract: 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 structu… Show more

“…19 Hence, Bi-based ionic crystals can be used as multiferroics, superconductors, high ionic conductors, photocatalysts, and photovoltaics. 16,17,[20][21][22][23] Bismuth-based semiconductors are a class of materials with special electronic and optical structures. [13][14][15]20,24 Due to the positive valence band position and strong oxidation ability of most bismuth-based semiconductors, they are ideal catalysts for water splitting and photocatalytic degradation of pollutants.…”

“…In addition to the substitution elements of Pb 2+ with the same valence, such as Sn 2+ and Ge 2+ , which can form a classical angle-shared octahedral perovskite structure with cations at the A site and halogen ions at the X site, elements with different valence from Pb 2+ , such as Ag + , Bi 3+ , and Sb 3+ , can also replace Pb 2+ at the B site to form a new perovskite structure. , Because the electronic configuration of 6s 2 6p 0 for Bi 3+ is the same as that of Pb 2+ , Bi 3+ is a suitable candidate to replace Pb 2+ which has lower toxicity and is more stable than Sn 2+ . In recent years, Bi 3+ has been widely utilized in the substitution of Pb 2+ and the formation of perovskite derivatives.…”

“…In the search for alternatives, chalcohalides are quickly gaining attention as semiconductors for multiple applications. For example, quaternary lead-free Sn 2 PnS 2 I 3 (where Pn = Sb or Bi) chalcohalides display some of the most desirable features of chalcogenide and halide materials, including direct, visible band gaps (<1.6 eV). Following their original discovery and crystallographic determination, these materials have earned renewed interest in photovoltaics, thermoelectrics, and catalysis applications. Furthermore, based on preliminary solar devices, tin chalcohalides are believed to exhibit inherently high stability and power conversion efficiency (PCEs), highlighting their potential as valuable materials for energy conversion. , …”
