Summary: Recent efforts have been made to address the lack of consensus on terminology and reporting of experimental results in the field of luminescent solar concentrators. This analysis aims to recommend clear and consistent terminology for future publications. The study suggests that luminescent solar concentrator photovoltaics (LSC-PV) should be treated as integrated photovoltaic cells and their power conversion efficiency (PCE) and external quantum efficiency (EQELsc(A)) should be reported. The term optical efficiency has been defined inconsistently and should be interpreted with caution. The validity and significance of the highest reported LSC efficiency metrics have been assessed.

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: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.
