Heavy pnictogen chalcohalides for efficient, stable, and environmentally friendly solar cell applications

Yong Chan Choi et al.

Summary: Solar cell technology is an effective solution for addressing climate change and the energy crisis. Researchers have revisited heavy pnictogen chalcohalides as emerging solar absorbers due to their potential for efficient, stable, and low-toxicity solar cell applications. This review explores the recent progress, categorizes them into different material types based on their common structural characteristics, and discusses their limitations, challenges, and possible strategies for further development.

Solution-Phase Synthesis and Photoluminescence of Quaternary Chalcohalide Semiconductors

Alison N. Roth et al.

Summary: Mixed-metal chalcohalide semiconductors, specifically Pb2SbS2I3 and Pb2BiS2I3, were synthesized in solution phase using readily available precursors. The reaction parameters were fine-tuned to produce rod-like structures with tunable dimensions. The quaternary chalcohalides exhibited photoluminescence both as an ensemble and at the single particle level, as observed through fluorescence microscopy. Electronic structure calculations were used to evaluate the stability and band gap of Pb2SbS2I3 polymorphs and their coloring patterns. These synthetic methods pave the way for further exploration of complex chalcohalides and other multinary semiconductors for new technological applications.

Mixed Valence of Bismuth in Hexagonal Chalcohalide Nanocrystals

Danila Quarta et al.

Summary: We have developed a colloidal synthesis method for bismuth chalcohalide nanocrystals with a hexagonal phase. The structure of these nanocrystals can be described by the Bi13S18X2 (where X = Br and I) model. It was found that the presence of Bi24+ dimers, formed by columns of Bi atoms, and Peierls-type distortions are responsible for the anomalously low band gap and intervalence charge transfer in this material. Our findings and synthetic approach provide fundamental understanding for the use of hexagonal bismuth chalcohalides in diverse applications such as photocatalysis and thermoelectrics.

Danila Quarta et al.

Summary: In this study, a colloidal approach was developed to synthesize bismuth chalcohalide nanocrystals (BiEX NCs) with adjustable band gaps. The obtained BiEX NCs exhibited chemical stability and solution processability, making them promising candidates for photoelectrochemical applications. The versatile synthetic protocol presented in this study could be valuable for the fabrication of colloidal metal chalcohalide nanomaterials.

Indirect Band Gap Semiconductors for Thin-Film Photovoltaics: High-Throughput Calculation of Phonon-Assisted Absorption

Jiban Kangsabanik et al.

Summary: The discovery of high-performance materials is an active field in photovoltaics research. This study proposes a computationally efficient method to screen potential thin-film PV absorbers by accounting for phonon-assisted absorption across the indirect band gap. Through screening descriptors, 28 candidate materials, including 20 indirect band gap semiconductors, were identified.
