“…Also, no quantum confinement effects are anticipated for the NCs due to their size of few hundred nanometers. This size is indeed much larger than the exciton Bohr radius of approximately 6 Å (0.6 nm) for AgBiI 4 , estimated using the 3D Wannier exciton model assuming a relative dielectric constant of 3.36, 24 and an effective average reduced mass of 0.33 m 0 . 43 Therefore, no specific enhancement of the emission is expected from excitonic effects.…”

“…Surface defects represent one of the most limiting factors in the performance and stability of Ag–Bi–I-based photovoltaic cells and photodetectors. Despite the various strategies to suppress these surface defects or imperfections, 13,14,23,24 their influence on the electronic properties of Ag–Bi–I remains largely unexplored. On the other hand, the surface atomic structure of lead-based NCs also influences their electronic structure as well as the structural and other material properties.…”

The search for efficient but inexpensive photovoltaics over the past decade has been disrupted by the advent of lead-halide perovskite solar cells. Despite impressive rises in performance, the toxicity and stability concerns of these materials have prompted a broad, interdisciplinary community across the world to search for lead-free and stable alternatives. A set of such materials that have recently gained attention are semiconductors in the CuI–AgI–BiI3 phase space and their derivatives. These materials include ternary silver bismuth iodide compounds (Ag aBi bI a+3 b), ternary copper bismuth iodide Cu–Bi–I compounds and quaternary Cu–Ag–Bi–I materials, as well as analogues with Sb substituted into the Bi site and Br into the I site. These compounds are comprised of a cubic close-packed sub-lattice of I, with Ag and Bi occupying octahedral holes, while Cu occupies tetrahedral holes. The octahedral motifs adopted by these compounds are either spinel, CdCl2-type, or NaVO2-type. NaVO2-type Ag aBi bI a+3 b compounds are also known as rudorffites. Many of these compounds have thus far demonstrated improved stability and reduced toxicity compared to halide perovskites, along with stable bandgaps in the 1.6–1.9 eV range, making them highly promising for energy harvesting and detection applications. This review begins by discussing the progress in the development of these semiconductors over the past few years, focusing on their optoelectronic properties and process–property–structure relationships. Next, we discuss the progress in developing Ag–Bi–I and Cu–Bi–I compounds for solar cells, indoor photovoltaics, photodetectors, radiation detectors and memristors. We conclude with a discussion of the critical fundamental questions that need to be addressed to push this area forward, and how the learnings from the wider metal-halide semiconductor field can inform future directions.

“…Anti-solvent-assisted crystallization strategy is a common method in perovskite photovoltaics to facilitate the removal of the residual solvent and delicately control the nucleation condition and crystallization rate of the perovskite film [ 33 , 34 , 35 ]. The selection of anti-solvent and deposition routes has great impact on the nucleation speed during the perovskite fabrication.…”

High absorption ability and direct bandgap makes lead-based perovskite to acquire high photovoltaic performance. However, lead content in perovskite becomes a double-blade for counterbalancing photovoltaic performance and sustainability. Herein, we develop a methylammonium bismuth iodide (MBI), a perovskite-derivative, to serve as a lead-free light absorber layer. Owing to the short carrier diffusion length of MBI, its film quality is a predominant factor to photovoltaic performance. Several candidates of non-polar solvent are discussed in aspect of their dipole moment and boiling point to reveal the effects of anti-solvent assisted crystallization. Through anti-solvent engineering of toluene, the morphology, crystallinity, and element distribution of MBI films are improved compared with those without toluene treatment. The improved morphology and crystallinity of MBI films promote photovoltaic performance over 3.2 times compared with the one without toluene treatment. The photovoltaic device can achieve 0.26% with minor hysteresis effect, whose hysteresis index reduces from 0.374 to 0.169. This study guides a feasible path for developing MBI photovoltaics.
