Summary: Through molecular dynamics simulation, the physical characteristics of nickel thin-films and nickel thin-film foams as anode and cathode current collectors in lithium-air batteries were investigated. The results provide theoretical guidance for understanding the physical attributes of current collectors and the interaction between air and electrolyte with cathode current collectors. The evaluation shows that nickel thin-films and their foams have suitable thermal and mechanical characteristics as anode and cathode current collectors. However, an oxygen selective membrane is necessary for the interfacial interaction between nickel thin-film foams and air and (CH3)2SO/LiPF6 nonaqueous electrolyte in LABs cells.

Summary: Lead halide perovskites are utilized in semiconductor devices as absorbers with low doping levels to achieve high surface photovoltage values. Drift-diffusion simulations show that under continuous illumination, intrinsic perovskite-SCTL structures can develop mV range surface photovoltages, while actual measurements confirm SPVs in the hundreds of mV. The compatibility between low doping and defect densities in the perovskite layer and high SPV values is analyzed using numerical modeling to understand the electronic processes contributing to long SPV persistence after the illumination is switched off.

Summary: This study investigates how chiral ligands attached to perovskite nanocrystal surfaces distort the perovskite lattice and demonstrates the resulting chiral electro-optical properties. The major finding is a centro-asymmetric distortion of the surface lattice, which is likely the cause of the chiral-optical properties. Spin-polarized transport through chiral nanocrystals amplifies the discrimination between left and right-handed circularly polarized light.

Summary: The optoelectronic properties of lead halide perovskite thin films can be tuned through compositional variations and strain. However, the nanocrystalline structure complicates the understanding of the link between composition, processing conditions, and material properties. In this study, the local photoconductivity dynamics of perovskite thin films were investigated under different processing conditions and degradation using microwave near-field microscopy. The results showed that the annealing temperature during the processing affected the film morphology, stability, and spatial photoconductivity distribution. Spectral evidence of halide segregation-induced degradation was found in the mixed halide formulation, while an increase in carrier lifetime was observed in the FACs formulation annealed at 180 degrees C.

Summary: In this study, electroluminescence (EL) and thermal imaging were used to investigate the degradation of metal halide perovskite (MHP) photovoltaic (PV) mini-modules. Different spatial patterns were observed in the EL images depending on the external stress conditions. Dark speckle features dominated after UV stress, while lateral intensity gradients were prominent after thermal cycling stress. Multimodal electro-optical imaging, including EL, photoluminescence and dark lock-in thermography, provided a deeper understanding of the degradation modes. UV exposure and thermal cycling stress testing alone could not replicate the same degradation signatures observed after outdoor deployment, indicating the occurrence of multiple degradation modes. The spatial characterization of degradation modes provides a foundation for developing targeted accelerated stress testing procedures by comparing with outdoor aging.
