Summary: Lead-halide perovskite materials have attracted significant attention for optoelectronics and photovoltaic applications due to their favorable electrical and optical properties, but their commercialization is hindered by lead toxicity and material stability issues. The development of lead-free perovskites, with tin as a potential candidate, is important for environmental sustainability. More efforts are needed to advance tin-based lead-free perovskite thin films for long term cost-effective solar energy technology.

Summary: Heterojunctions play a crucial role in tailoring the properties of semiconductors in optoelectronic devices. However, fabricating perovskite/perovskite heterojunctions in metal halide perovskite devices has been challenging due to solvent incompatibilities and rapid homogenization caused by ion migration. Recent studies have shown that perovskite nanocrystals can be used to fabricate perovskite/perovskite heterojunctions, offering advantages in terms of optical and electrical properties.

Summary: Elpasolite Cs2AgBiBr6, also known as double perovskite, has been considered as a potential substitute for lead-based perovskite in light harvesting. Despite its improved stability, Cs2AgBiBr6 exhibits inferior photophysical properties and device performance compared to lead-based perovskites. The limitations are attributed to its low electronic dimensionality (0D), formation of small polaronic states, and interfacial imperfections with charge transporting layers. This review discusses the compositional and interlayer interactions of Cs2AgBiBr6 in solar cells, evaluates its suitability for photovoltaic applications, and suggests potential measures to enhance its performance. Additionally, the potential application of Cs2AgBiBr6 in photocatalysis, taking advantage of its lower toxicity and better stability, is also discussed.

Summary: This study presents a rapid method to extract decay rate ratios using photoluminescence quantum efficiency measurements. The approach is applied to halide perovskite thin-film samples and is shown to provide accurate results compared to the more time-consuming technique of transient absorption spectroscopy. The study also reveals that radiative recombination is only a fraction of total second-order recombination in the relevant range of halide perovskite samples for photovoltaics. The findings highlight the importance of reducing first-order losses to improve solar cell efficiency.

Summary: The band gap tunability of lead mixed halide perovskites makes them promising in optoelectronics. The static disorder due to iodide:bromide compositional alloying contributes at most 3 meV to the Urbach energy. The small effective masses in perovskites result in a natural length scale for confining potential, explaining the small contribution of potential fluctuations to Urbach energy.

Summary: Long-chain organic halide salts are widely used in perovskite-based optoelectronic devices for surface passivation. By introducing aluminum oxide (AlOx) onto octylammonium iodide (OAI) through atomic layer deposition, the benefits of organic halide salts can be utilized without generating undesired defects. The OAI/AlOx devices show improved performance and photo-stability compared to the treated devices, with a diffusion of aluminum from AlOx into the perovskite contributing to uniform carrier transport. In addition, light-induced two-dimensional perovskite formation is observed on OAI/AlOx, which prevents the loss of OA cations and suppresses the light-induced degradation of the devices.

Summary: We developed a simple and efficient method to synthesize highly luminescent CsPbBr3 nanocrystals and investigated their scintillation properties. The addition of a small amount of surfactant oleylamine played a crucial role in controlling the size and emission properties of the nanocrystals. The resulting perovskite nanocrystals exhibited high photoluminescence quantum yield and stability. We also prepared CsPbBr3 nanocrystal-loaded polymer composites and studied their emission properties, showing potential applications in scintillator devices and X-ray imaging.

Summary: In this study, methylammonium-free, co-evaporated FA(0.7)Cs(0.3)Pb(I0.9Br0.1)(3) perovskite solar cells were fabricated and tested, demonstrating their high tolerance to high-energetic radiation and potential for high power-to-weight ratios, making them suitable for future space PV applications. The absence of methylammonium greatly improved the UV-light stability, which is important considering the increased UV proportion in the extra-terrestrial solar spectrum. By using injection-current-dependent electroluminescence (EL) and intensity-dependent V-OC measurements, the pseudo-JV methodology was employed to analyze the damage mechanisms and to determine the perovskite's degradation under high energetic proton irradiation. The results showed a high radiation tolerance of 0.96 initial PCE, surpassing current space material systems and comparable to solution-processed perovskite solar cells.
