Summary: In this study, the stability of small polarons in methylammonium lead iodide perovskite is investigated using density functional theory. It is found that the electron small polaron is unstable, while the hole small polaron is metastable at realistic operation temperatures. The hole polaron, with its close proximity to the conduction band and metastability, is expected to have a significant impact on charge-carrier recombination.

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: This study investigates the crystallization mechanisms of flash infrared-annealed perovskite films grown on substrates with lithographically patterned Au nucleation seeds. The study shows that by increasing the nucleation site density, the proportion of larger crystallites is increased, leading to longer charge carrier lifetimes in regions with large crystallites on the domain boundaries. This combination of rapid thermal annealing with nucleation control is a promising approach to improve perovskite crystallinity and the performance of optoelectronic devices.

Summary: Through pressure-dependent transient absorption spectroscopy experiments, it was found that pressure has an influence on hot-carrier cooling behavior in metal halide perovskites, with the upper limit above the Mott transition. The results indicate that above this transition, pressure can promote faster hot-carrier cooling, suggesting a change in the electronic behavior of devices at high charge-carrier densities.

Summary: Layered Dion-Jacobson (DJ) and Ruddlesden-Popper (RP) hybrid perovskites with modular structure are promising for optoelectronic applications. By using mechanical stimuli, their properties can be controlled without changing the composition. This study investigates the structure-property relationships of DJ and RP 2D perovskites under hydrostatic pressure and reveals the changes in lattice and optical properties. Surprisingly, RP and DJ perovskites behave similarly under pressure despite the different spacer molecules. The manipulation of crystal structure affects the optoelectronic properties, and the reversibility of their response expands future application prospects.

Summary: In this study, the impact of C60-passivation layers on Cs0.15FA0.85PbI2.75Br0.25 double-cation perovskite solar cells was quantified. Impedance spectroscopy, photoluminescence spectroscopy, and X-ray diffraction were used to identify the reasons for the increase in power conversion efficiencies and operational stability in solar cells with C60/ZnO electron transport layer compared to reference cells. The results revealed that C60 led to the formation of PbI2-rich and Br-rich regions in the perovskite absorber layer, reducing recombination losses and improving operational stability.

Summary: This perspective highlights the strategies to manipulate strain in lead halide perovskites at different length scales, and the effects of compressive and tensile strain on ion migration and phase segregation. The role of lattice polarizability and reduced unit cell volume in suppressing phase segregation is emphasized. The potential of using the apparent weaknesses of this class of materials (softness and phase segregation) as a strength is also discussed.

Summary: Through mechanochemical synthesis, controlled replacement of Bi3+ with Fe3+ enables tunable absorption onset between 2.1 and approximate to 1 eV. First-principles density functional theory (DFT) calculations suggest that this reduction in bandgap mainly originates from a decrease in the conduction band upon introduction of Fe3+, and predict a direct bandgap with >50% of Bi3+ replaced with Fe3+. The tunability of the conduction band energy is reflected in the photoredox activity of these semiconductors. These findings open new avenues for enhancing the sunlight absorption of double perovskite semiconductors and harnessing their full potential in sustainable energy applications.
