Summary: This study investigated the mechanical-photovoltaic properties of flexible solar cells and found that they are limited by strain in terms of power generation efficiency. The decline in fill factor was found to occur at a lower strain than mechanical properties and voltage output. Changes in geometry and reinforcing materials did not prevent the early initiation of fill factor decline.

Summary: This study reports the multi-peak structures in the low-temperature photoluminescence spectra of CsPbBr3 nanocrystals, including excitons, trions, and biexcitons. The fine-structure splitting is observed in the photoluminescence peaks of bright excitons and biexcitons, as well as in the longitudinal-optical-phonon replicas of excitons. The size-dependent analysis shows that the coupling between excitons and phonons, as well as between trions and phonons, becomes stronger for smaller nanocrystals. These findings provide essential information for understanding electron-phonon couplings in perovskites and for the development of high-purity single-photon sources.

Summary: We generated intense mid-infrared pulses with a tunable wavelength range of 5.3-7.4 μm and a pulse energy of up to 6.2 μJ. This was achieved through white-light generation, intra-pulse difference frequency generation (DFG), and optical parametric amplification. The use of intra-pulse DFG allowed for the generation of carrier-envelope phase (CEP)-stable mid-infrared optical pulses, with a CEP standard deviation of 114 mrad during a 5-hour-long measurement.

Summary: Electric vehicles have the advantage of resilience to natural disasters, but users hesitate to donate electricity when they lose the chance to recharge at the utility. Solar electric vehicles, through vehicle-integrated photovoltaics, can save energy and enable voluntary donation of excess energy, thus maintaining facility resilience. This study investigates the potential of vehicle-integrated photovoltaics to maintain utility resilience considering physical factors like irradiance and social factors.

Summary: In this study, the temperature dependence of the photoluminescence (PL) spectra of perovskite FAPbBr(3) and CsPbBr3 nanoparticles was investigated. The results showed that the PL linewidths were mainly influenced by the Frohlich interaction between excitons and longitudinal optical phonons. A redshift in the PL peak energy was observed between 100 and 150 K for FAPbBr(3) nanoparticles, which was attributed to the orthorhombic-to-tetragonal phase transition. It was also found that the phase transition temperature of FAPbBr(3) nanoparticles decreased as the nanoparticle size decreased.

Summary: The authors studied HoFeO3 crystal using multicycle THz magnetic pulses enhanced strongly by spiral-shaped microstructure. The observed Faraday ellipticity demonstrates second- and third-order harmonics of the magnetization oscillation and an asymmetric oscillation behavior. The ability to drive a spin system to state far from the equilibrium is indispensable for investigating spin structures of antiferromagnets and their functional nonlinearities for spintronics.

Summary: Development of PV-powered vehicles is crucial for a carbon neutrality society as vehicle integrated PVs have the potential to significantly reduce CO2 emissions in the transport sector. The use of high-efficiency solar cell modules is essential due to limited installation area on vehicle exteriors. This article presents driving data of a Toyota Prius installed with a high-efficiency III-V compound triple-junction solar cell module, achieving an efficiency of over 30%. The results demonstrate an average daily driving distance of 17 km/day with air conditioning, and a 62% CO2 emission reduction through actual driving in Nagoya, Japan. Additionally, analytical results show the impact of high-efficiency VIPV modules (>35%) on increasing the average daily driving distance by over 30 km/day and reducing CO2 emissions from PV-powered vehicles by over 70%.
