Summary: In this work, two novel compounds [Et3S][AuI4][I-5] (2) were synthesized by ionic liquid (IL) and applied as active layers in monolithic solar cells. These compounds are composed of tetraiodoaurate anions and polyiodide entities, with infinite polyiodide chains in 1 and pentaiodides in 2, resulting in relatively small electronic bandgaps. The deposition of gold iodide/polyiodide compounds onto porous monolithic substrates with subsequent solar cell characterization is demonstrated for the first time in this study. The devices show promising photovoltaic performance and offer new possibilities for materials design, moving away from lead-based photovoltaic materials. The use of simple polyiodide entities in this study enhances the structural and electronic dimensionality of gold perovskite-type anions.

Summary: Oxygen ingression has been shown to decrease the carrier lifetime of Sn-based perovskites, and our calculations reveal that oxygen tends to form substitutional OI, which remarkably increases the recombination rate of native I vacancies (VI). This explains the observed decline of carrier lifetime in perovskites exposed to air. The enhanced carrier recombination is due to a smaller electron capture barrier of OI, resulting from lattice strengthening and suppressed structural relaxation upon electron capture. These insights offer a route to improve device performance in Sn-based perovskite optoelectronics operating in ambient air.

Summary: Oxygen ingression has been shown to decrease the carrier lifetime of Sn-based perovskites, but the mechanism behind this is unknown. First-principles calculations reveal that oxygen forms substitutional O-I by combining with native I vacancies (V-I), significantly increasing the recombination rate of V-I. This explains the sharp decline of carrier lifetime in perovskites exposed to air. These insights offer a way to improve device performance in Sn-based perovskite optoelectronics operating in ambient air through anion engineering.

Summary: This study evaluated the adsorption of gaseous iodine [I-2(g)] on five different metal coupons under controlled conditions. Humidity was found to play a critical role in iodine adsorption on SS304, SS316, and Ni-200 at ambient temperatures. The results showed that a moisture-mediated reaction is occurring and higher humidity levels decrease adsorption. The comparison of the metal substrates showed that Ni-200 had the highest adsorption, followed by SS304, SS316, 718, and 625. The findings provide insights into predicting iodine adsorption behaviors on various metal surfaces under near-ambient conditions.

Summary: Weakly coupling halide perovskite quantum dots (PeQDs) to plasmonic lattices can significantly change their photoluminescence pattern, converting the incoherent randomly oriented emitters into a spatially coherent source of polarized light. By optimizing the thickness of the perovskite layer and combining plasmonic lattices of different symmetries, simultaneous shaping of the emission pattern can be achieved, paving the way for designing solid-state lighting applications with programmable emission patterns.

Summary: Two-dimensional (2D) organic-inorganic hybrid perovskites are a promising alternative to three-dimensional (3D) perovskites for solar cell applications due to their improved stability, versatility, and ease of processing. However, the insulating nature of the organic cations limits their absorbing and conducting properties, leading to lower device efficiencies. This study introduces a solution by incorporating functional molecules that can polymerize within the perovskite layers, resulting in significant changes in the materials' optoelectronic properties and stability. The results highlight the versatility of this approach and provide valuable insights into the chemical nature of the polymerized species, paving the way for their use in optoelectronic devices.

Summary: Modulated self-assembly protocols have been used to develop efficient, HF-free syntheses of flexible PCPs (metal-organic framework materials) MIL-53(Cr), MIL-53(Cr)-Br, and MIL-53(Cr)-NO2. These PCPs exhibit excellent SO2 uptake and high chemical stability against dry and wet SO2. Solid-state photoluminescence spectroscopy reveals that all three PCPs can effectively sense SO2, especially MIL-53(Cr)-Br, which shows a 2.7-fold decrease in emission upon exposure to SO2 at room temperature, suggesting potential sensing applications.
