“…These results are debated: Correa-Baena et al derived the above exciton binding energy values based on the default assumption that the observed PL is associated with free exciton recombination. However, other investigations of the PL emission of these materials demonstrates that the observed PL is associated with the recombination of selftrapped excitons, hence the thermal quenching of the PL cannot be traced to the exciton binding energy (McCall et al, 2017;Mei et al, 2021.). It has to be mentioned that zero-dimensional Cs 3 Sb 2 I 9 features considerably stronger exciton self-trapping than the two-dimensional counterparts, reflecting the more prominent trapping effects taking place with lower structural dimensionality (Mei et al, 2021).The cation substitution impacts the films morphology: the Cs 3 Sb 2 I 9 film comprised small grains, while those of Rb 3 Sb 2 I 9 and K 3 Sb 2 I 9 displayed much larger grains (Correa-Baena et al, 2018).…”

In recent decades, many technological advances have been enabled by nanoscale phenomena, giving rise to the field of nanotechnology. In particular, unique optical and electronic phenomena occur on length scales less than 10 nanometres, which enable novel applications. Halide perovskites have been the focus of intense research on their optoelectronic properties and have demonstrated impressive performance in photovoltaic devices and later in other optoelectronic technologies, such as lasers and light-emitting diodes. The most studied crystalline form is the three-dimensional one, but, recently, the exploration of the low-dimensional derivatives has enabled new sub-classes of halide perovskite materials to emerge with distinct properties. In these materials, low-dimensional metal halide structures responsible for the electronic properties are separated and partially insulated from one another by the (typically organic) cations. Confinement occurs on a crystal lattice level, enabling bulk or thin-film materials that retain a degree of low-dimensional character. In particular, quasi-zero dimensional perovskite derivatives are proving to have distinct electronic, absorption, and photoluminescence properties. They are being explored for various technologies beyond photovoltaics (e.g. thermoelectrics, lasing, photodetectors, memristors, capacitors, LEDs). This review brings together the recent literature on these zero-dimensional materials in an interdisciplinary way that can spur applications for these compounds. The synthesis methods, the electrical, optical, and chemical properties, the advances in applications, and the challenges that need to be overcome as candidates for future electronic devices have been covered.

“…To investigate the bandgap of Ag-Bi-I thin films, researchers have relied on their optical absorption spectra and density functional theory (DFT) calculations. Compared to bismuth-based hybrid perovskite-inspired materials such as double perovskites and A 3 BiX 9 compounds (where A is a monovalent cation such as Cs + /Rb + /CH 3 NH 3 + and Xis a halide anion such as I -/ Br -/Cl -), which are limited by their wide indirect bandgaps (E g > 2.0 eV), [30,34,36,[125][126][127] Ag-Bi-I materials have a considerably smaller bandgap in the range of 1.55-1.82 eV (indirect) and 1.6-1.93 (direct), [38,39,42,79,90] as determined from the Tauc analysis of their UV-vis absorption spectra, which is more favorable for photovoltaic applications. The wide range in the bandgap of silver bismuth iodides arises from different compositions and synthesis conditions.…”

In the wake of lead-halide perovskite research, bismuth-and antimony-based perovskite-inspired semiconducting materials are attracting increasing attention as safer and potentially more robust alternatives to lead-based archetypes. Of particular interest are the group IB-group VA halide compositions with a generic formula A x B y X x+3y (A + = Cu + /Ag + ; B 3+ = Bi 3+ /Sb 3+ ; X -= I -/Br -), i.e., silver/copper pnictohalides and derivatives thereof. This family of materials forms 3D structures with much higher solar cell efficiencies and greater potential for indoor photovoltaics than the lower-dimensional bismuth/ antimony-based perovskite-inspired semiconductors. Furthermore, silver/ copper pnictohalides are being investigated for applications beyond photovoltaics, e.g., for photodetection, ionization radiation detection, memristors, and chemical sensors. Such versatility parallels the wide range of possible compositions and synthetic routes, which enable various structural, morphological, and optoelectronic properties. This manuscript surveys the growing research on silver/copper pnictohalides, highlighting their composition-structure-property relationships and the status and prospects of the photovoltaic and optoelectronic devices based thereon. The authors hope that the insights provided herein might accelerate the development of eco-friendly and stable perovskiteinspired materials for next-generation photovoltaics and optoelectronics.
