description: In the past years, the advantages of solid state lighting technologies led to the development of
fully light emitting diode (LED) based solar simulators. In this paper we have compared the
characterization capabilities of a prototype version of the LED sun simulator with a
commercially available two lamps (Xenon and Halogen) based Class AAA sun simulator using
mono-crystalline silicon solar cells. Standard solar cell characterization tests were performed on
both simulators under similar operating conditions as per IEC 60904-9. The results of the
measurements show that the LEDs based simulator can not only perform as good as the
commercial conventional simulator, but also that it can perform better in terms of stability and
tunability. In order to characterize solar cells more closely to reality, a new spectrum definition
that can be achieved by existing lighting technologies with reasonable burden is proposed using
PC1D calculations for different industrial cell types.

description: An expression for optical absorbance in Si solar cells is derived, which is a simplification of the expression
for the same quantity given by Basore. Unlike the Basore expression, the simplified expression does not require the determination
of the front-surface external and internal reflectance prior to be used. For a textured solar cell, it is equivalent
to the Basore expression, if the average ray-path angle with respect to the surface normal is equal at all passes of light
across the cell. Unlike the Basore expression, it allows fitting the measured quantum efficiency of not-textured solar cells
with diffuse rear surface. The simplified expression can be easily implemented in the numerical simulation program
PC1d. The measured quantum efficiency of a textured solar cell is fitted with both the new and Basore expressions. Overlapping
fit-curves are obtained. The measured quantum efficiency of a not-textured solar cell with not-polished rear surface
is fitted by using the new expression. Finally, with the new expression, the maximum absorbance for weakly absorbed
light is estimated in solar cells with textured back surface at both flat and textured front surfaces.

description: Two types of the solar simulators were compared in several types of experiments involving crystalline
silicon, amorphous silicon solar cells and test structures of transparent oxides and buffer layers used in thin film solar
cells. Photo response of solar cells illuminated by commercially available Xenon arc based simulator was used as a
benchmark for comparison. Compact light emitting diode (LED) based solar simulator with six LED groups of
different colors was the second illumination source in our study. AAA class requirements are met by both solar
simulators, but substantial performance differences appear when testing various devices. These differences are
attributed to the differences of quantum efficiency spectra of measured devices, surface reflectivity variations for
mini-modules and an increase of photo response non-uniformity once the photocurrent contribution is reduced from
several diode groups. Numerical calculations for multilayer structures were used for further comparison studies and
were employed to clarify the possible origin of the observed phenomena.

description: Further development and commercialization of the new generation of optoelectronic and
photovoltaic is often limited by the necessity of fabrication of low-cost and efficient transparent conductive
electrodes. The development so far is hindered by the conveniently used indium tin oxide (ITO), which suffers
from high cost and not high enough availability to support mass production. The zinc oxide is emerging as a
convenient replacement for ITO for solar cell and light-emitting diode applications. The optical functions of
aluminum-doped zinc oxide thin films are determined using optical spectroscopy measurements from 300 to 1100
nm. The dopant range studied varies from intrinsic ZnO to 5% Al content. Below the direct band gap there is a
residual enhancement of the optical absorption coefficient by Al dopants, which is not related to surface
roughness. We determined the dielectric functions and absorption coefficient evolution as the dopant
concentration increases, as well as the free-carrier concentration.

description: The modulation of band gap in the two-dimensional carbon materials is of impor- tance for their applications as electronic devices. By first-principles calculations, we propose a model to control the band gap size of γ-graphyne. The model is named as p-n codoping, i. e., using B and N atoms to codope into γ-graphyne. After codoping, B atom plays a role of p doping and N atom acts as n doping. The Fermi energy level returns around the forbidden zone and the band gap of γ-graphyne vary bigger or smaller. Moreover, the gaps exhibit an oscillated behaviour in different codoping configurations. The proposed model serves as new insights for better modulation of the electronic properties of 2D carbon materials.

description: To counter the mismatch in solar panels due to partial shading reconfiguring the cell layouts can prove
to be very costly. We instead propose that optimized static cell layouts maximize the energy yield of photovoltaic
panels and could be a suitable solution for panels prone to partial shading especially in building integrated PV. We
generate 52 layouts under chosen constraints and study them under two common shade scenarios, namely tree and
chimney. These layouts include series and parallel connections of the cell-strings and vary in the number and the
placement of bypass diodes in the panel. We also compare the performance of the different layouts under uniform
irradiance conditions and show that they perform equally well.

description: We propose to use metal nanogrids to enhance light absorption in ultrathin GaAs solar cells with
120 nm-thick and 220 nm-thick absorbers. Thanks to the transfer of the cells on a silver back mirror leading to Fabry
Perot resonances in the semiconductor cavity, the short circuit current is increased by 40%. With an additional antireflection
coating and a nanostructured back mirror, we obtain Jsc=17.4 mA/cm2 and 21.2 mA/cm2 for 120 nm and
220 nm-thick absorbers, respectively. It represents a two-fold enhancement of the Jsc compared to the non-transferred
solar cells. We also show that is possible to realize really absorptive semiconductor devices within a few tens of
nanometers. As a proof of concept, a super-absorber device consisting of a front nanogrid deposited on a 25 nm-thick
GaAs layer absorbs more than 80% of the light over the 450-830 wavelength range.

description: The separation of oxygen- and carbon-rich AGB sources is crucial for their accurate use as local and cosmological distance and age/metallicity indicators. We investigate the use of unsupervised learning algorithms for classifying the chemistry of long-period variables from Gaia DR3's BP/RP spectra. Even in the presence of significant interstellar dust, the spectra separate into two groups attributable to O-rich and C-rich sources. Given these classifications, we utilise a supervised approach to separate O-rich and C-rich sources without BP/RP spectra but instead given broadband optical and infrared photometry finding a purity of our C-rich classifications of around $95$ per cent. We test and validate the classifications against other advocated colour-colour separations based on photometry. Furthermore, we demonstrate the potential of BP/RP spectra for finding S-type stars or those possibly symbiotic sources with strong emission lines. Although our classification suggests the Galactic bar-bulge is host to very few C-rich long-period variable stars, we do find a small fraction of C-rich stars with periods $>250\,\mathrm{day}$ that are spatially and kinematically consistent with bar-bulge membership. We argue the combination of the observed number, the spatial alignment, the kinematics and the period distribution disfavour young metal-poor star formation scenarios either in situ or in an accreted host, and instead, these stars are highly likely to be the result of binary evolution and the evolved versions of blue straggler stars already observed in the bar-bulge.

as a function of the absorber thickness) exceed the previous theoretical limits for light trapping in solar cells.

dependence of I-V curves. Influence of flow ratio of CH4 and SiH4 on built-in voltage was evaluated from the

description: An innovative approach for decreasing the optical shadowing of grid lines of solar cells is to form
volume optics in the encapsulating Ethylene-vinyl acetate (EVA) layer by femtosecond (fs-)laser structuring. Recent
results on this ongoing research topic are presented. In particular, the chemical changes of the EVA material upon
interaction with a fs-laser pulse were investigated by applying confocal Raman microscopy. Moreover, a careful
investigation on the optical properties of the EVA volume optics was performed: (i) experimentally on the basis of
goniometric measurements of diffractive micro-structures, as well as (ii) theoretically by applying optical modeling
and optimization procedures. This resulted in a better understanding of the effectiveness of the optical volume
elements in decreasing the shadowing of metal grid lines on the active cell surfaces. Moreover first results of minimodules
with incorporated volume optics are presented. Results of optical simulation and Laser Beam Induced
Current (LBIC) experiments show that the losses due to grid fingers can be reduced by about 50% by creating microoptics
in the volume of the EVA by fs-laser structuring.

description: The surfaces of metal oxides often are reconstructed with a geometry and composition that is considerably different from a simple termination of the bulk. Such structures can also be viewed as ultrathin films, epitaxed on a substrate. Here, the reconstructions of the SrTiO3 (110) surface are studied combining scanning tunneling microscopy, transmission electron diffraction, and X-ray absorption spectroscopy, and analyzed with density functional theory calculations. While SrTiO3 (110) invariably terminates with an overlayer of titania, with increasing density its structure switches from nx1 and 2xn. At the same time the coordination of the Ti atoms changes from a network of corner-sharing tetrahedra to a double layer of edge-shared octahedra with bridging units of octahedrally coordinated strontium. This transition from the nx1 to 2xn reconstructions is a transition from a pseudomorphically stabilized tetrahedral network towards an octahedral titania thin film with stress-relief from octahedral strontia units at the surface.

description: We propose an experimental method for sensitive detection of carrier interaction and filtering in hot
carrier PV structures. The method was successfully tested on PbSe/InP heterostructure. Development of the method
required extension of Richardson’s thermionic emission theory towards the case of small barrier heights.
Remarkably, the exact solution including Fermi-Dirac statistics was obtained in a simple closed form. It includes the
Richardson’s solution as a specific case. We applied linear thermal conductivity model for estimation of the carrier
temperature vs. heating power dependence. The new generalized theory allows quantitative interpretation of the
experimental data, however, the temperature of the hot electron gas turned out to be very large.

description: New insight into the potential of practical solar cells can be given through alternative modelling
approaches like Monte Carlo simulations. In the present work, the performance of a stack of cells connected in series
was examined at different levels of Quantum Efficiency. Incident photons, generated from a Planck Equation for
Black Body Radiation at 6000K, are accounted for as they interact with the stack of cells. The values of the different
bandgaps were not chosen to give optimum performance of the device. It was demonstrated that by reducing the
device Quantum Efficiency, the overall device efficiency would increase to a certain maximum level before
decreasing. This effect is due to a lack of device balance. With a certain decrease in the Quantum Efficiency, the
device was shown to achieve better current balance in the cells leading to a higher overall device efficiency.

description: We propose a scheme to realize a lossless propagation of linear and nonlinear Airy surface polaritons (SPs) via active Raman gain (ARG). The system we suggest is a planar interface superposed by a negative index metamaterial (NIMM) and a dielectric, where three-level quantum emitters are doped. By using the ARG from the quantum emitters and the destructive interference effect between the electric and magnetic responses from the NIMM, we show that not only the Ohmic loss of the NIMM but also the light absorption of the quantum emitters can be completely eliminated. As a result, non-diffractive Airy SPs may propagate for very long distance without attenuation. We also show that the Kerr nonlinearity of the system can be largely enhanced due to the introduction of the quantum emitters and hence lossless Airy surface polaritonic solitons with very low power can be generated in the system.

description: The quadrupole collectivity of low-lying states and the anomalous behavior of the $0^+_2$ and $2^+_3$ levels in $^{72}$Ge are investigated via projectile multi-step Coulomb excitation with GRETINA and CHICO-2. A total of forty six $E2$ and $M1$ matrix elements connecting fourteen low-lying levels were determined using the least-squares search code, gosia. Evidence for triaxiality and shape coexistence, based on the model-independent shape invariants deduced from the Kumar-Cline sum rule, is presented. These are interpreted using a simple two-state mixing model as well as multistate mixing calculations carried out within the framework of the triaxial rotor model. The results represent a significant milestone towards the understanding of the unusual structure of this nucleus.

description: We show that the maximal number of (real) lines in a (real) nonsingular spatial quartic surface is 64 (respectively, 56). We also give a complete projective classification of all quartics containing more than 52 lines: all such quartics are projectively rigid. Any value not exceeding 52 can appear as the number of lines of an appropriate quartic.

description: Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object can be used as an orbiting X-ray point source to probe the wind and constrain its clumpiness. We perform spectro-timing analysis of the HMXB OAO 1657-415 with non-simultaneous NuSTAR and NICER observations. We compute the hardness ratio from the energy-resolved light curves, and using an adaptive rebinning technique, we thus select appropriate time segments to search for rapid spectral variations on timescales of a few hundreds to thousands of seconds. Column density and intensity of Iron K$α$ line were strongly correlated, and the recorded spectral variations were consistent with accretion from a clumpy wind. We also illustrate a novel framework to measure clump sizes, masses in HMXBs more accurately based on absorption measurements and orbital parameters of the source. We then discuss the limitations posed by current X-ray spacecrafts in such measurements and present prospects with future X-ray missions. We find that the source pulse profiles show a moderate dependence on energy. We identify a previously undetected dip in the pulse profile visible throughout the NuSTAR observation near spin phase 0.15 possibly caused by intrinsic changes in accretion geometry close to the neutron star. We do not find any evidence for the debated cyclotron line at $\sim$ 36\,keV in the time-averaged or the phase-resolved spectra with NuSTAR.

description: Periodic nanostructures have shown great potential for light management in thin crystalline silicon (c-Si)
wafer solar cells thanks to their compatibility with thin absorber layers and capability to enhance light absorption
effectively. In this work, we compare three types of different periodic nanostructures with reference to a planar solar
cell and discuss the important considerations to evaluate their optical properties based on numerical simulation. The
absorbed photocurrent density for textured samples with a thickness of 5 μm ranges from 33.0 to 34.5 mA/cm2. This
1.5 mA/cm2 difference corresponds to 5.8% of the absorbed photocurrent density of planar samples with the same
thickness. We demonstrate that the optical performance of such periodic nanostructures is a joint effect of their
antireflective and macroscopic light trapping properties as well as the spatial absorption distribution profile in the solar
cell. Based on the presented findings, optimum periodic nanostructure placed at the front and rear surface should be
designed accordingly with different considerations regarding antireflective and light trapping properties.

description: Reflected sunlight observations from the Ultraviolet Spectrograph (UVS) on the Juno spacecraft were used to study the distribution of acetylene (C$_2$H$_2$) at Jupiter's south pole. We find that the shape of the C$_2$H$_2$ absorption feature varies significantly across the polar region, and this can be used to infer spatial variability in the C$_2$H$_2$ abundance. There is a localized region of enhanced C$_2$H$_2$ absorption which coincides with the location of Jupiter's southern polar aurora; the C$_2$H$_2$ abundance poleward of the auroral oval is a factor of 3 higher than adjacent quiescent, non-auroral longitudes. This builds on previous infrared studies which found enhanced C$_2$H$_2$ abundances within the northern auroral oval. This suggests that Jupiter's upper-atmosphere chemistry is being strongly influenced by the influx of charged auroral particles and demonstrates the necessity of developing ion-neutral photochemical models of Jupiter's polar regions.

description: The grain-boundary light-beam-induced-current (GB-LBIC) technique is a versatile method for
simultaneous determination of grain and grain boundary (GB) properties in polycrystalline semiconductors and semiinsulators
without the need of charge collection by p-n juctions or Schottky contacts. Here, the GB itself acts as
charge collector and generates a characteristic peak-and-trough (PAT) current profile. We investigate by 2D optoelectronic
numerical simulations the nature of this PAT signal on different models for the GB. We find that generally
the charge at the grain-boundary that causes a built-in-field around the GB is responsible for the PAT signal.
However, a PAT can also be generated for structures with a high resistivity GB or a high recombination GB, without
built-in fields. Moreover, these findings will demonstrate that the GB-LBIC method allows the determination - in
materials with grain boundaries - of the minority carrier diffusion length of the grain bulk, without being influenced
by GB recombination.
Development of the RFQ Cooler SHIRaC: beam transport and nuclearization

description: The development of the new RFQ Cooler, called SHIRaC, was carried out. As a part of SPIRAL 2 facility, SHIRaC aims to handle and cool typical SPIRAL 2 beams with large emittances (up to 80 pi.mm.mrad) and high currents (up to 1 uA). Its purposes are to enhance as much as possible the beam quality (transverse geometric emittance of less than 3 pi.mm.mrad and longitudinal energy spread close to 1 eV) and to transmit more than 60 % of ions. Numerical simulations and experimental studies have shown that the required beam quality can be reached only in term of the emittance. The energy spread is very far from expected values. It is sensitive to the space charge and the buffer gas diffusion and more importantly to the RF field derivative effect. The latter arises at the RFQ exit and increases with the RF parameters (the frequency and the amplitude of the RF voltage). Studies allowing to enhance the cooled beam quality, mainly the energy spread reduction, are presented and discussed along this paper. They consist in implementing a miniature RFQ at the RFQ exit. Using this method, it becomes possible to improve the cooled beam quality and to reach 1 eV of longitudinal energy spread and around 1.75 π.mm.mrad of transverse geometric emittance for beam currents going up to 1 uA. The transport of the cooled beam from SHIRaC towards a HRS has been done with an electrostatic quadrupole triplet. Simulations and first experimental tests showed that more than 95 % of cooled beams can reach the HRS. Finally, developments related to the nuclearization protection methods aiming to avoid the escape of any nuclear matter from the SHIRaC beamline are studied.

description: Active comets have been detected in several exoplanetary systems, although so far only indirectly, when the dust or gas in the extended coma has transited in front of the stellar disk. The large optical surface and relatively high temperature of an active cometary coma also makes it suitable to study with direct imaging, but the angular separation is generally too small to be reachable with present-day facilities. However, future imaging facilities with the ability to detect terrestrial planets in the habitable zones of nearby systems will also be sensitive to exocomets in such systems. Here we examine several aspects of exocomet imaging, particularly in the context of the Large Interferometer for Exoplanets (LIFE), which is a proposed space mission for infrared imaging and spectroscopy through nulling interferometry. We study what capabilities LIFE would have for acquiring imaging and spectroscopy of exocomets, based on simulations of the LIFE performance as well as statistical properties of exocomets that have recently been deduced from transit surveys. We find that for systems with extreme cometary activities such as beta Pictoris, sufficiently bright comets may be so abundant that they overcrowd the LIFE inner field of view. More nearby and moderately active systems such as epsilon Eridani or Fomalhaut may turn out to be optimal targets. If the exocomets have strong silicate emission features, such as in comet Hale-Bopp, it may become possible to study the mineralogy of individual exocometary bodies. We also discuss the possibility of exocomets as false positives for planets, with recent deep imaging of alpha Centauri as one hypothetical example. Such contaminants could be common, primarily among young debris disk stars, but should be rare among the main sequence population. We discuss strategies to mitigate the risk of any such false positives.

description: An ideal Hot Carrier cell would absorb a wide range of photon energies and extract a large fraction of
the energy to give very high efficiencies, up to 65% at 1 sun (85% at max concentration) [1,2]. Required absorber
properties have been defined and some materials and superstructures exhibit slowed carrier cooling. Fabrication of
materials that can slow carrier cooling through enhancing phonon bottleneck is challenging. Optical coupling of the
energy of hot carriers allows a greater range of materials for absorbers and independent optimisation of optical,
phononic and electrical properties of the system. It offers the best near term approach to realising the hot carrier cell
and may offer the best long term prospects for very high efficiencies.
Resistivity plateau and extremely large magnetoresistance in NbAs2 and TaAs2

description: In topological insulators (TIs), metallic surface conductance saturates the insulating bulk resistance with de- creasing temperature, resulting in resistivity plateau at low temperatures as a transport signature originating from metallic surface modes protected by time reversal symmetry (TRS). Such characteristic has been found in several materials including Bi2Te2Se, SmB6 etc. Recently, similar behavior has been observed in metallic com- pound LaSb, accompanying an extremely large magetoresistance (XMR). Shubnikov-de Hass (SdH) oscillation at low temperatures further confirms the metallic behavior of plateau region under magnetic fields. LaSb[1] has been proposed by the authors as a possible topological semimetal (TSM), while negative magnetoresistance is absent at this moment. Here, high quality single crystals of NbAs2/TaAs2 with inversion symmetry have been grown and the resistivity under magnetic field is systematically investigated. Both of them exhibit metallic behavior under zero magnetic field, and a metal-to-insulator transition occurs when a nonzero magnetic field is applied, resulting in XMR (1.0*105% for NbAs2 and 7.3*105% for TaAs2 at 2.5 K & 14 T). With tempera- ture decreased, a resistivity plateau emerges after the insulator-like regime and SdH oscillation has also been observed in NbAs2 and TaAs2.
