Summary: This study employs a synergistic approach combining first-principles atomistic modeling with numerical device simulations to investigate the role of heterointerfaces in metal-chalcogenide-based photovoltaic technologies. The atomic-scale study of two interfaces in cadmium-telluride-based thin-film solar cells reveals the mechanisms contributing to device performance variations. Computational results show contrasting electronic structures and charge transport behavior between the Schottky barrier forming Al/CdTe interface and the Type I Te/CdTe heterojunction. The cadmium termination exhibits greater band bending features compared to the tellurium termination, leading to a 3.6% higher photovoltaic conversion efficiency for the cadmium termination. This research highlights the importance of atomic-scale interfacial properties for the performance of cadmium telluride solar cells.

Summary: The transition to low-emission energy generation, storage, and transport requires increased metal production. However, most of the metals needed for these technologies are considered critical and are currently supplied as low volume byproducts. Thin-film cadmium-telluride photovoltaics are a promising alternative to silicon-based solar panels. This study presents new scenarios for tellurium supply and demand and explores how improved byproduct critical metal recovery can be driven by market demand and low-emission energy generation.

Summary: Colloidal cesium lead bromide perovskite nanocrystals are densely packed into thin films using the doctor blade method, and their optical properties are significantly improved through ligand exchange with sodium and potassium nitrate. Passivation of ligand-induced surface defects by sodium and potassium cations and nitrate leads to enhanced photoluminescence and carrier lifetime properties. Alkali metal nitrate salts treated films exhibit higher photoluminescence intensity and longer carrier lifetime compared to the pristine capped films, indicating their potential for achieving defect-free inorganic perovskite nanocrystal films.

Summary: The rapid removal of Congo red (CR), a stable anionic diazo dye with carcinogenic properties, was investigated using cation-incorporated nanohydroxyapatite (pristine HAp: X (X = Fe, Ni, Zn, Co, and Ag)). The incorporation of dopant ions significantly modified the properties of the adsorbent, leading to a rapid and efficient removal of CR dye. Fe-HAp exhibited the highest CR adsorption capacity and regeneration efficiency, making it a potential adsorbent for CR removal without byproduct formation.

Summary: The limited light absorption range of organic dyes has hindered the significant development and large-scale applications of dye-sensitized solar cells (DSSC). The major issue is the inability of organic dyes to absorb light beyond the visible region of the solar spectrum, resulting in lower power conversion efficiency (PCE). Therefore, developing efficient strategies to utilize the ultraviolet and infrared regions of the solar spectrum and convert them into the absorption limit of dyes is crucial for enhancing DSSC performance and stability. Rare earth ion-doped upconversion and downconversion phosphors offer promising solutions for these issues.

Summary: This study investigates the AlN nucleation layer issue in GaN high frequency telecommunication and power switching systems fabricated after heteroepitaxy on Silicon or Silicon Carbide. It is shown that using 3C-SiC as an intermediate layer can significantly decrease RF propagation losses. Measurements and analyses demonstrate that dopant diffusion into the 3C-SiC pseudo-substrate is confined beneath the interface, and a slightly conductive zone is present beneath the AlN/3C-SiC interface, explaining the low propagation losses obtained for the devices. This work highlights the importance and efficiency of the 3C-SiC intermediate layer as a pseudo-substrate.
