Summary: Luminescent solar concentrators (LSCs) have the potential to improve solar energy capture when coupled to traditional photovoltaics (PV) by concentrating direct and diffuse solar radiation onto a smaller area of PV. However, LSCs suffer from various optical losses that are difficult to quantify with simple power conversion efficiency measurements. In this study, we used spatially resolved photoluminescence quantum efficiency measurements to identify and analyze different loss processes in large-area LSCs, including out-coupling, self-absorption via emitters, and self-absorption from the LSC matrix. These measurements also provided insights into the optimization of optical properties and guided the design of future LSCs for improved solar energy capture.

Summary: Modeling the bandwidth limits of Luminescent Solar Concentrators (LSCs) offers vital insights into their behavior and provides a technique for evaluating their use in various applications. Although LSCs have emerged as a promising receiver technology in free-space optical communications due to their ability to collect light from a wide field-of-view and concentrate it into small areas, the comparably slow timescale of their fluorescence events may pose a bottleneck on the bandwidth of high-speed communication systems. A team of researchers led by Ioannis Papakonstantinou from University College London has developed a technique that delineates the fundamental limits of LSCs as optical detectors and demonstrated time-domain Monte-Carlo simulation for optimizing LSC based receiver systems. The work opens the door for the use of LSCs in applications in visible light communications, high-speed video recording, and real-time biological imaging.

Summary: The aim of this study is to investigate the hydrogen sorption kinetics and thermodynamics of Mg-Ni nanoparticles at low temperature, focusing on their microstructure. The findings show that Mg-Ni nanoparticles exhibit fast hydrogen sorption kinetics at 150 degrees C, but the maximum hydrogen storage capacity is limited due to the lack of transformation from Mg2NiH0.3 to Mg2NiH4 at this temperature. Partial replacement of Ni with Fe does not significantly affect the hydrogen sorption thermodynamics and kinetics.

Summary: Intensity-modulated photocurrent spectroscopy (IMPS) is widely used in characterizing semiconductor-based devices for solar energy conversion. However, the analysis of IMPS data for complex structures is often limited to a semi-quantitative description of charge carrier kinetics. In this study, a new algorithm based on the distribution of relaxation times (DRT) is developed, providing unprecedented time resolution for investigating charge carrier dynamics in semiconductor-based systems. The algorithm, modified with a Lasso regression method, reveals hidden charge transfer paths in a-Fe2O3 photoanodes for photoelectrochemical water splitting.

Summary: The solar-driven oxidation of biomass to valuable chemicals is being explored as a promising anodic reaction in photoelectrochemical cells, with the aim of replacing the slow oxygen evolution reaction and improving energy conversion efficiency. In this study, the photooxidation of 5-hydroxymethylfurfural into furan dicarboxylic acid (FDCA) was carried out in a basic aqueous environment using titanium-modified hematite (Ti:Fe2O3) photoanodes. The addition of Co-based cocatalysts, specifically cobalt iron oxide (CoFeO x ) and cobalt phosphate (CoPi), improved the performance of the photoanodes, particularly the electrode modified with CoPi, which showed enhanced efficiency and selectivity towards FDCA production. The improved performance is attributed to the cocatalyst's effect on charge carrier dynamics and suppression of recombination processes.
