Summary: Passivating the interfaces between the perovskite and charge transport layers is crucial for enhancing the power conversion efficiency (PCE) and stability in perovskite solar cells (PSCs). In this study, a dual-interface engineering approach was used to improve the performance of FA0.85MA0.15Pb(I0.95Br0.05)3-based PSCs by incorporating Ti3C2Clx Nano-MXene and o-TB-GDY NanoGDY into the electron transport layer (ETL)/perovskite and perovskite/ hole transport layer (HTL) interfaces, respectively. The resulting perovskite film exhibited an ultralong carrier lifetime and an enlarged crystal size, leading to a high PCE of 24.86% and long-term stability.

Summary: In this study, an ultra-thin ImAcCl layer was used to modify tin perovskite solar cells, resulting in multifunctional improvements and a significant enhancement in power conversion efficiency (PCE). The carboxylate group and hydrogen bond donor in ImAcCl effectively suppressed Sn2+ oxidation and reduced trap density in perovskite films. The modified interface also reduced roughness and promoted the formation of high-quality tin perovskite films with improved crystallinity and compactness. Moreover, the modification of the buried interface facilitated the formation of large bulk-like crystals, enhancing charge carrier transport and suppressing recombination. As a result, the PCE of tin PSCs increased from 10.12% to 12.08%.

Summary: Recent experimental advances in perovskite solar cell technology have brought about a new era in low-cost, flexible, and high-efficiency photovoltaics. However, the study of the detailed physical mechanisms governing the optoelectronic properties of these solar cells has not kept pace with experimental breakthroughs. This article aims to bridge this gap by using a coupled optical and electrical modeling approach to optimize and assess the transport properties of photonic-structured perovskite solar cells. The findings show that ultrathin perovskite absorbers can significantly enhance light coupling and photocurrent generation, leading to increased short circuit current, open-circuit voltage, fill factor, and power conversion efficiency.

Summary: We conducted a study on Wurtzite AlGaAs using both experimental and numerical methods, and found that it is a technologically promising yet unexplored material. By developing a complete numerical model based on an 8-band (k) over right arrow center dot(p) over right arrow method, including electromechanical fields, we calculated the optoelectronic properties of wurtzite AlGaAs nanowires with different Al content and compared them with experimental data. Our results strongly indicate that wurtzite AlGaAs is a direct band gap material. Additionally, we numerically obtained the band gap of wurtzite AlAs and the valence band offset between AlAs and GaAs in the wurtzite symmetry.

Summary: This article presents new insights into stabilizing p-i-n perovskite solar cells (PSCs) and modules using CsCl additives. The inclusion of chlorine in the perovskite crystal structure resulted in decreased lattice parameters, increased bandgap value, and longer charge carrier lifetimes. The champion PSCs based on the CsFAPbI(3-x)Cl(x) absorber showed improved power conversion efficiency and increased light-soaking stability. Additionally, the potential of Cl-anion engineering for perovskite modules was demonstrated, achieving high efficiency and stability.

Summary: In this study, the electronic and optical properties of InGaN single quantum wells with thin GaN cap-layers were investigated. A significant spectral shift of quantum well emission was observed for cap-layer thicknesses between 1 and 10 nm. The origin of this shift was explained by calculations and the influence of alloy fluctuations and homogeneity was studied on both the microscale and nanoscale using UV micro-Raman scattering and TERS. The results demonstrated the capabilities of TERS to resolve nanoscale thickness fluctuations and compositional inhomogeneities in ultra-thin semiconductor layers.

Summary: In this study, we investigate the interface between (RuPc)2 and the Ag(001) surface. Two different commensurable arrangements of the molecules are observed at different coverage densities on the substrate. The focus of the study is on the evolution of interface states with molecular density and the charge distribution in the thin interfacial layer between molecules and substrate. The results reveal different valence band structures and charge modulations for the two molecular arrangements, making (RuPc)2/Ag(001) an interesting case of intermediate interaction between physisorption and chemisorption.

Summary: By combining high-resolution X-ray photoelectron spectroscopy, thermal programmed desorption, and density functional theory calculations, we found that hydrogen chemisorption on graphene is temperature-independent between 150 and 320 K, while H intercalation below graphene is limited by an energy barrier of about 150 meV. Moreover, the graphene cover can significantly enhance hydrogen storage in the interface with the bare Ni(111) substrate, especially in heavily hydrogenated samples.

Summary: This article investigates a possible solution for high-efficiency visible light-emitting diodes (LEDs) using InGaN-quantum-dot-based active regions. Numerical simulations are conducted on a single InGaN island with a size of ten nanometers and nonuniform indium content distribution, which is restored from an experimental image. Various two- and three-dimensional models of the quantum dot are derived, and different calculations and predictions are performed. The impact of InGaN composition fluctuations on the ground-state electron and hole wave functions and quantum dot emission spectrum is analyzed in detail. The applicability of various simulation approaches is assessed by comparing the predicted spectrum with the experimental one.

Summary: Organometal halide perovskites (OMHP) are promising materials for fast, sensitive, and large area photodetectors. In this study, a controlled growth of OMHP single crystals in the form of microwires directly on conductive patterned substrates was achieved using a microfluidics-assisted technique. The resulting vertical devices with a pixelated sensor layer exhibit gain, a responsivity up to 200 AW(-1), and a fast rise time down to 35 µs. This is the first demonstration of an OMHP vertical device on a patterned substrate using microfluidics-assisted techniques.

Summary: The emission properties of InGaN/GaN nanowires grown by plasma-assisted molecular beam epitaxy are investigated using various techniques, revealing the roles of inhomogeneous In distribution and radial fields in the emission properties. The radial built-in fields are found to be modest, while variations in the local In content have a greater impact. Two luminescence bands with large positive and moderate negative polarization ratios were observed, associated with In-rich inclusions and spontaneously formed superlattices in the nanowires.

Summary: The influence of self-assembled short-period superlattices (SPSLs) on the structural and optical properties of InGaN/GaN nanowires (NWs) grown by PAMBE on Si (111) was studied. SPSLs were found to self-assemble during growth in most of the studied nanostructures, demonstrating a short-range ordering of In-rich and In-poor InxGa1-xN regions. The polarized photoluminescence analysis revealed that the NWs exhibited parallel polarized red-yellow emission and perpendicular polarized blue emission, attributed to different In-rich regions.
