Summary: This study compares and evaluates the metal halide treatments of CdTe films and CIGS, finding that CdTe films have lower manufacturing costs, while CIGS requires higher temperatures and lower rates to achieve high efficiency. Silver halides are beneficial for the transport of all species, while compounds containing gallium and indium may pose some issues. Copper compounds have low vapor pressure but exhibit high mobility in CIGS.

Summary: Post-deposition treatments with indium bromide vapor at 400 and 500 degrees Celsius lead to larger grains and higher conductivity in Cu(In,Ga)Se-2 thin films compared to simple annealing under selenium. These properties are attributed to a modification of elemental profiles, particularly for gallium and sodium.

Summary: The purpose of this study is to propose a novel flexible skin dosimeter based on a thin-film copper indium gallium selenide (CIGS) solar cell and evaluate its dosimetric characteristics. The CIGS solar cell dosimeter showed good performance in terms of dose measurement linearity, sampling rate effect, dose rate dependence, energy dependence, and field size output factor. It is a low-cost dosimeter that can be easily customized, providing advantages over other dosimeters.

Summary: This study presents a synthetic approach to produce polytypic CuInSe2 nanocrystals with variable morphologies, including tetrapods, core/shell structures, and hollow structures. These nanostructures consist of a chalcopyrite phase core and wurtzite phase arms or shells, and their size and morphology can be tuned by adjusting the nucleation temperature.

Summary: In this study, highly (001) oriented Sb2Se3 nanorod layers were obtained via a novel template growth method and transferred to functional substrates. Photodetector devices with excellent electrical contact were fabricated using a low-temperature processable SnO2 nanoparticle transport layer and encapsulation/etching techniques. A proof-of-concept self-powered flexible heart rate monitor was also fabricated based on this platform. The achievement of transferable Sb2Se3 nanorod layers has significant implications for the development of new device architectures and potential applications in various fields.

Summary: 2D semiconductors show great potential in various fields, but current fabrication methods have limitations. This study demonstrates a bottom-up approach for high-quality, wafer-scale 2SEM based on the wide band gap gallium selenide compound. The optical properties of the layers are utilized for photon sensing in the UV spectrum, offering a scalable route to deep-UV optoelectronics.

Summary: A facile fabrication strategy of highly efficient and stable wide-bandgap perovskites (PVSKs) was demonstrated through an organic halide surface treatment. The surface post-treatment resulted in the complete conversion of PVSK crystallinity, eliminating segregated secondary phases and reducing unreacted PbI2. The reconstructed PVSK showed enhanced photovoltaic performance and high stability, achieving a power conversion efficiency of 24.5% in a tandem device.

Summary: In this paper, a method for passivating interface and grain boundary defects in perovskite solar cells (PSCs) is proposed by dissolving the passivation materials in mixed solvents of IPA and toluene. The performance parameters of PSCs are improved, resulting in an increased power conversion efficiency (PCE). Moreover, a 4-terminal perovskite/CIGS tandem device is achieved with a high PCE, demonstrating the potential of the mixed solvent passivation strategy in enhancing the efficiency and stability of PSCs.

Summary: Cu(In,Ga)Se-2 thin films and devices were fabricated using a modified three-stage process, with a copper chloride vapor treatment introduced to enhance film properties. After recrystallization, films showed larger grains, but not all parameters of the solar cells were enhanced, resulting in only a 15% increase in device efficiency.

Summary: The study demonstrates that surface doping with AuCl3 can enhance the performance of InSe photodetectors, surpassing previously reported 2D material-based infrared photodetectors. Investigation of InSe photodetectors with different structures provides insights into the photodetection mechanism and performance optimization. Additionally, encapsulation with hexagonal boron nitride dielectric enables long-term stability of the devices for up to 3 months.

Summary: The depth dependent UV-light absorption profile of GaN nanorods with different lattice arrays and filling factors was studied using finite-difference time-domain (FDTD) methods. By comparing to the results from LambertBeer's law with Maxwell-Garnett effective medium theory, we identified the quantitative contribution from nano-scattering effect on the light absorption in the nanorod arrays. The FDTD study of graphical 3D profile of light absorption and electric field intensity was parallelly conducted to investigate the origin of the nano scattering.

Summary: This study explores the potential use of hot water-treated (HWT) aluminum foil in preventing bacterial growth on red meat. The efficacy of HWT foils in different temperatures was tested, with results showing 95-100% effectiveness in preventing bacterial growth due to improved release of reactive oxygen species from nanostructures and physical rapturing mechanism associated with membrane penetration. This research offers a nontoxic and cost-effective solution for curbing foodborne illnesses caused by bacteria.
