description: Aims: We aim to determine the effect of converging flows on the evolution of a bipolar magnetic region (BMR), and to investigate the role of these inflows in the generation of poloidal flux. We also discuss whether the flux dispersal due to turbulent flows can be described as a diffusion process. Methods: We developed a simple surface flux transport model based on point-like magnetic concentrations. We tracked the tilt angle, the magnetic flux and the axial dipole moment of a BMR in simulations with and without inflows and compared the results. To test the diffusion approximation, simulations of random walk dispersal of magnetic features were compared against the predictions of the diffusion treatment. Results: We confirm the validity of the diffusion approximation to describe flux dispersal on large scales. We find that the inflows enhance flux cancellation, but at the same time affect the latitudinal separation of the polarities of the bipolar region. In most cases the latitudinal separation is limited by the inflows, resulting in a reduction of the axial dipole moment of the BMR. However, when the initial tilt angle of the BMR is small, the inflows produce an increase in latitudinal separation that leads to an increase in the axial dipole moment in spite of the enhanced flux destruction. This can give rise to a tilt of the BMR even when the BMR was originally aligned parallel to the equator.

Silicon Solar Cell Characterisation and Modelling

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 412-416
description: In this study, a multi-layer metallization concept for high-efficient large-area silicon back-contact back-junction solar cells is investigated. The metallization approach represents an industrial alternative to the well-known edge-to-edge cell interconnection technology, allowing for a decoupling of the cell metallization from the external contact structure by inserting an intermediate insulation layer. A first proof of principle is shown for an n type back-contact back-junction solar cell with an edge length of 156 mm and evaporated aluminum grid fingers. Furthermore, we present a tool that allows for the design optimization of the contact layout by combining detailed cost of ownership calculations with analytical solar cell simulations. Two back-end process sequences are compared and for both approaches the most cost-effective metallization layout is determined on cell level. Finally, a sensitivity analysis is carried out, revealing the high potential of the investigated back-contact back junction solar cell structures.

description: Lattice translation symmetry gives rise to a large class of "weak" topological insulators (TIs), characterized by translation-protected gapless surface states and dislocation bound states. In this work we show that space group symmetries lead to constraints on the weak topological indices that define these phases. In particular we show that screw rotation symmetry enforces the Hall conductivity along the screw axis to be quantized in multiples of the screw rank, which generally applies to interacting systems. We further show that certain 3D weak indices associated with quantum spin Hall effects (class AII) are forbidden by the Bravais-lattice and by glide or even-fold screw symmetries. These results put a strong constraints on candidates of weak TIs in the experimental and numerical search for topological materials, based on the crystal structure alone.

description: After the golden age of Japanese PV manufacturers, Japanese company’s presence is weakening in
recent years. But, the new efforts to encourage Japanese PV industry have begun. The one is the new NEDO’s R&D
project that is the consortium in cooperation with industry, government and academia for development of crystalline
Si solar cell. In addition, the pilot production line was constructed as the industrial development platform. Utilizing
these frameworks, we have been concurrently developing several technologies to realize high efficiency and low cost
crystalline Si solar cell all along the value chain as follows; (1) Seed-cast growth of large square mono Si using one
small single seed crystal, (2) Slicing technique of 100 m thick wafer with 100 m kerf-loss, (3) Simplified PERL
cell suitable for mass-production, and (4) Ag/Cu double screen printing metallization. As a result of our concurrent
development all along value chain of crystalline Si solar cell, we confirmed the feasibility of the next generation
crystalline Si solar cell fabrication process that satisfies some requirements, that is, high efficiency, low cost and high
profitability on investment.

description: Using data from eROSITA, the soft X-ray instrument aboard Spectrum-Roentgen-Gamma (SRG), we report the discovery of two new hard transients, eRASSU J050810.4-660653 and eRASSt J044811.1-691318, in the Large Magellanic Cloud. We also report the detection of the Be/X-ray binary RX J0501.6-7034 in a bright state. We initiated follow-up observations to investigate the nature of the new transients and to search for X-ray pulsations coming from RX J0501.6-7034. We analysed the X-ray spectra and light curves from our XMM-Newton observations, obtained optical spectra using the South African Large Telescope to look for Balmer emission lines and utilised the archival data from the Optical Gravitational Lensing Experiment (OGLE) for the long-term monitoring of the optical counterparts. We find X-ray pulsations for eRASSU J050810.4-660653, RX J0501.6-7034, and eRASSt J044811.1-691318 of 40.6 s, 17.3 s, and 784 s, respectively. The Halpha emission lines with equivalent widths of -10.4 A (eRASSU J050810.4-660653) and -43.9 A (eRASSt J044811.1-691318) were measured, characteristic for a circumstellar disc around Be stars. The OGLE I- and V-band light curves of all three systems exhibit strong variability. A regular pattern of deep dips in the light curves of RX J0501.6-7034 suggests an orbital period of ~451 days. We identify the two new hard eROSITA transients eRASSU J050810.4-660653 and eRASSt J044811.1-691318 and the known Be/X-ray binary RX J0501.6-7034 as Be/X-ray binary pulsars.

description: This work deals with quantifying the internal optical losses in a Cu plated n-Si rear junction cell. The
focus is on the following 2 losses : (i) Free Carrier Absorption (FCA) in the highly doped regions of the device and
(ii) non-ideal internal reflectance at the rear of the device. For the FCA, optical measurements have been used to
quantify the loss of photons in both the n+ diffused Front Surface Field (FSF) and p+ emitter regions of the device. It
is shown that this loss is negligible for the P- and B-doped layers used in imec’s n-Si rear junction cells and amounts
to a combined loss in short-circuit current of only 0.1 mA/cm2. External reflectance measurements have also been
employed to quantify the internal rear reflectance in the device as function of the nature and thickness of the rear
dielectric layers. Predictive calculations indicate an improved internal rear reflectance by switching from the original
dielectric stack (thermal oxide + PECVD nitride) to a single dielectric layer (> 100nm thermal oxide), which has been
confirmed experimentally. Such implementation into imec’s n-Si rear junction cells has helped to improve the
efficiency to levels above 21%.

description: We study theoretically wave-vector and frequency dispersion of the complex dynamic conductivity tensor (DCT), $σ_{lm}(\mathbf{k}, ω)$, of doped monolayer graphene under a strong dc electric field. For a general analysis, we consider the weak ac field of arbitrary configuration given by two independent vectors, the ac field polarization and the wave vector $\mathbf{k}$. The high-field transport and linear response to the ac field are described on the base of the Boltzmann kinetic equation. We show that the real part of DCT, calculated in the collisionless regime, is not zero due to dissipation of the ac wave, whose energy is absorbed by the resonant Dirac quasiparticles effectively interacting with the wave. The role of the kinematic resonance at $ω= v_F |{\bf k}|$ ($v_{F}$ is the Fermi velocity) is studied in detail taking into account deviation from the linear energy spectrum and screening by the charge carriers. The isopower-density curves and distributions of angle between the ac current density and field vectors are presented as a map which provides clear graphic representation of the DCT anisotropy. Also, the map shows certain ac field configurations corresponding to a negative power density, thereby it indicates regions of terahertz frequency for possible electrical (drift) instability in the graphene system.

beyond 60% and quantum dots inserted in the intrinsic region of IBSCs, will play an essential role in the realizing this

Krastanov (SK) growth mode has been popular over years. Recently, sub-monolayer (SML) growth was suggested as
an alternative. Dots formed by this new method are expected to provide better confinement as compared to
conventional one. In this paper, we present study of optimization of number of stacks followed by post growth

description: A energy conversion efficiency of 25.1% was achieved in the Heterojunction Back Contact (HBC) structure Si solar cell utilizing Back Contact (BC) technology and an amorphous silicon thin film solar cell production technology. Short circuit current density (Jsc) and open circuit voltage (Voc) were 41.7 mA/cm2 and 736 mV, respectively. The high Jsc as well as the high Voc indicates that the strength of HBC structure cell concept was realized. Besides, fill factor (F.F.) was a high value of 0.819, which shows that HBC structure cell doesn’t have fundamental critical losses because of series resistance or leak current.

description: We consider the random transverse-field Ising model in $d=3$ dimensions with long-range ferromagnetic interactions which decay as a power $α> d$ with the distance. Using a variant of the strong disorder renormalization group method we study numerically the phase-transition point from the paramagnetic side. The distribution of the (sample dependent) pseudo-critical points is found to scale with $1/\ln L$, $L$ being the linear size of the sample. Similarly, the critical magnetization scales with $(\ln L)^χ/L^d$ and the excitation energy behaves as $L^{-α}$. Using extreme-value statistics we argue that extrapolating from the ferromagnetic side the magnetization approaches a finite limiting value and thus the transition is of mixed-order.

description: The nuclear stellar disc (NSD) is a flat dense stellar structure at the heart of the Milky Way. Recent work has shown that analogous structures are common in the nuclei of external spiral galaxies, where there is evidence of an age gradient that indicates that they form inside-out. However, the characterisation of the age of the NSD stellar population along the line of sight is still missing due to its extreme source crowding and the high interstellar extinction towards the Galactic centre. We aim to characterise the age of the stellar population at different average Galactocentric NSD radii to investigate for the first time the presence of an age gradient along the line of sight. We selected two groups of stars at different NSD radii via their different extinction and proper motion distribution. We analysed their stellar population by fitting their de-reddened $K_s$ luminosity functions with a linear combination of theoretical models. We find significant differences in the stellar population at different NSD radii, indicating the presence of an age gradient along the line of sight. Our sample from the closest edge of the NSD contains a significant fraction ($\sim40 \%$ of its total stellar mass) of intermediate-age stars (2-7 Gyr) that is not present in the sample from stars deeper inside the NSD, in which $\sim90 \%$ of the stellar mass is older than 7 Gyr. Our results suggest that the NSD age distribution is similar to the one found in external galaxies and they imply that bar-driven processes observed in external galaxies are similarly at play in the Milky Way.

description: Imaging Science Subsystem (ISS) mounted on the Cassini spacecraft has taken a lot of images, which provides an important source of high-precision astrometry of some planets and satellites. However, some of these images are degraded by trailed stars. Previously, these degraded images cannot be used for astrometry. In this paper, a new method is proposed to detect and compute the centers of these trailed stars automatically. The method is then performed on the astrometry of ISS images with trailed stars. Finally, we provided 658 astrometric positions between 2004 and 2017 of several satellites that include Enceladus, Dione, Tethys, Mimas and Rhea. Compared with the JPL ephemeris SAT427, the mean residuals of these measurements are 0.11 km and 0.26 km in right ascension and declination, respectively. Their standard deviations are 1.08 km and 1.37 km, respectively. The results show that the proposed method performs astrometric measurements of Cassini ISS images with trailed stars effectively.

description: This article offers sharp spatial and temporal mean-square regularity results for a class of semi-linear parabolic stochastic partial differential equations (SPDEs) driven by infinite dimensional fractional Brownian motion with the Hurst parameter greater than one-half. In addition, mean-square numerical approximation of such problem are investigated, performed by the spectral Galerkin method in space and the linear implicit Euler method in time. The obtained sharp regularity properties of the problems enable us to identify optimal mean-square convergence rates of the full discrete scheme. These theoretical findings are accompanied by several numerical examples.

Reconstructing the history of water ice formation from HDO/H2O and D2O/HDO ratios in protostellar cores

description: Recent interferometer observations have found that the D2O/HDO abundance ratio is higher than that of HDO/H2O by about one order of magnitude in the vicinity of low-mass protostar NGC 1333-IRAS 2A, where water ice has sublimated. Previous laboratory and theoretical studies show that the D2O/HDO ice ratio should be lower than the HDO/H2O ice ratio, if HDO and D2O ices are formed simultaneously with H2O ice. In this work, we propose that the observed feature, D2O/HDO > HDO/H2O, is a natural consequence of chemical evolution in the early cold stages of low-mass star formation: 1) majority of oxygen is locked up in water ice and other molecules in molecular clouds, where water deuteration is not efficient, and 2) water ice formation continues with much reduced efficiency in cold prestellar/protostellar cores, where deuteration processes are highly enhanced due to the drop of the ortho-para ratio of H2, the weaker UV radiation field, etc. Using a simple analytical model and gas-ice astrochemical simulations tracing the evolution from the formation of molecular clouds to protostellar cores, we show that the proposed scenario can quantitatively explain the observed HDO/H2O and D2O/HDO ratios. We also find that the majority of HDO and D2O ices are likely formed in cold prestellar/protostellar cores rather than in molecular clouds, where the majority of H2O ice is formed. This work demonstrates the power of the combination of the HDO/H2O and D2O/HDO ratios as a tool to reveal the past history of water ice formation in the early cold stages of star formation and when the enrichment of deuterium in the bulk of water occurred. Further observations are needed to explore if the relation, D2O/HDO > HDO/H2O, is common in low-mass protostellar sources.

In this paper, we report simultaneous optical spectroscopic and photometric observations of a stellar superflare on an active M dwarf YZ CMi with the 3.8-m Seimei telescope and the $Transiting\, Exoplanet\, Survey\, Satellite$. The flare bolometric energy was $1.3^{+1.6}_{-0.6} \times 10^{34} \,\rm{erg}$ and H$α$ energy was $3.0^{+0.1}_{-0.1} \times 10^{32} \,\rm{erg}$. The H$α$ emission line profile showed red asymmetry throughout the flare with a duration of $4.6-5.1 \,\rm{hrs}$. The velocity of the red asymmetry was $\sim 200-500 \,\rm{km\,s^{-1}}$ and line width of H$α$ was broadened up to $34 \pm 14$ $Å$. The redshifted velocity and line width of H$α$ line decayed more rapidly than the equivalent width, and their time evolutions are correlated with that of the white-light emission. This indicates a possibility that the white light, H$α$ red asymmetry, and H$α$ line broadening originate from nearly the same site, i.e., the dense chromospheric condensation region heated by non-thermal electrons. On the other hand, the flux ratio of the redshifted excess components to the central components is enhanced one hour after the flare onset. This may be due to the change of the main source of the red asymmetry to the post-flare loops in the later phase of the flare.

description: By this report, a new complex self-organized technology of surface-barrier solar cells fabrication for
the enhancement their efficiency has been proposed. The elaborated technology for polar semiconductors III-V
(GaAs) is based on fabrication of grate-like microrelif by wet chemical anisotropic etching with following deposition
of noble metals (Au) nanowires on the ridges of it or deposition of separate nanoparticles (Ag), for comparing. This
allows us to realize the double effect of SC efficiency enhancement owing to light trapping on this relief and to light
scattering by plasmonic metal nanoparticles. Besides, the array of metal nanowires creates a multifunctional grid: for
surface plasmon polaritons excitation, for current collection, for decrease of the surface recombination velocity, for
forming the current-carrying contact on texturized front surface. The comprehensive investigation by AFM technique,
optical reflectance spectroscopy, photoelectric and electrical measurements on these SC allowed us to find out
essential enhancement of both the short-circuit photocurrent and the SC efficiency. Our theoretical modeling
confirmed existence of double effect of textured active interface and of the surface plasmons/plasmon polaritons
(SP/SPP) excitation leading to essential increase of SC efficiency using low cost technology.

description: The discovery of galaxies with regularly rotating discs at redshifts $\geq$ has been a puzzling challenge to galaxy formation models that tend to predict chaotic gas kinematics in the early Universe as a consequence of gas accretion, mergers and efficient feedback. In this work, we investigated the kinematics of five highly resolved galaxies at z $\sim$ 4.5 observed with ALMA in the [CII] 158 $μ$m emission line. The sample is diverse: AzTEC1 (starburst galaxy), BRI1335-0417 (starburst and quasar host galaxy), J081740 (normal star-forming galaxy) and SGP38326 (two starburst galaxies in a group). The five galaxies show velocity gradients, but four were found to be rotating discs while the remaining, AzTEC1, is likely a merger. We studied the gas kinematics of the discs using 3DBAROLO and found that they rotate with maximum rotation velocities between 198 and 562 km/s while the gas velocity dispersions, averaged across the discs, are between 49 and 75 km/s. The rotation curves are generally flat and the galaxies have ratios of ordered-to-random motion (V/$σ$) between 2.7 and 9.8. We present CANNUBI, an algorithm for fitting the disc geometry of rotating discs in 3D emission-line observations prior to modelling the kinematics, with which we find indications that these discs may have thicknesses of the order of 1 kpc. This study shows that early disc formation with a clear dominance of rotation with respect to turbulent motions is present across a variety of galaxy types.

description: Inspired by the successful synthesis of several allotropes, boron sheets have been one of the hottest spot areas of focus in various fields. Here, we study phonon transport in three types of boron nanoribbons with zigzag and armchair edges by using a non-equilibrium Green's function combined with first principles methods. Diverse transport properties are found in the nanoribbons. At the room temperature, their highest thermal conductance can be comparable with that of graphene, while the lowest thermal conductance is less than half of graphene's. The three boron sheets exhibit different anisotropic transport characteristics. Two of these sheets have stronger phonon transport abilities along the zigzag edges than the armchair edges, while in the case of the third, the results are reversed. With the analysis of phonon dispersion, bonding charge density, and simplified models of atomic chains, the mechanisms of the diverse phonon properties are discussed. Because all boron allotropes consists of hexagonal and triangular rings, many hybrid patterns can be constructed naturally without doping, adsorption, and defects. Our results are useful in materials and devices design using boron sheets for thermal management.

description: Boron-oxygen related defects typically limit the efficiency of solar cells made from silicon containing
high concentrations of boron as well as oxygen. The detrimental effect of these defects can be eliminated by applying
a Regeneration procedure that needs carrier injection at slightly elevated temperatures. The kinetics of this process is
influenced by different processing steps like thermal treatment and was found to rely on a high enough hydrogen
concentration in the silicon bulk. It is shown here that neither emitter formation nor the use of Al2O3/SiNx:H or
SiO2/SiNx:H passivation stacks affect Regeneration in a fundamental way. By contrast, the thickness of a SiNx:H
layer acting as hydrogen source during a high temperature firing step has direct influence on Regeneration confirming
that better hydrogenation results in faster Regeneration reactions. Condensing different process steps that all
accelerate Regeneration allows the application of a high-speed Regeneration process consisting of a combination of
relatively high temperature and high carrier injection, resulting in complete Regeneration of BO defects in less than
10 s. This makes Regeneration feasible as an in-line process in solar cell production and thus solves the problem of
the boron-oxygen defects. Even further acceleration is achieved by laser induced Regeneration where the substrate is
heated and illuminated simultaneously.

description: In this paper we incorporate non-imaging optics in up-conversion-photovoltaic (UC-PV) devices based on -NaYF4:Er3+ and planar bifacial silicon solar cells with antireflective coatings optimised for UC. The UC-PV devices were characterised under monochromatic illumination covering the excitation spectrum of the UC phosphor between 1450 and 1590 nm. Here, we present recent results that exhibit up to a two-fold increase in external quantum efficiency of UC-PV devices. This is not only a significant enhancement compared to UC-PV devices without any concentrating optics, but introduces a novel concept that enables system integration and could lead to additional enhancement after further optimisation.

description: AgInTe2 was introduced as an alternative for bottom cells for high efficient tandem solar cells. Thin
films were fabricated by RF sputtering deposition on glass substrates under ambient Ar for duration of 30 min using
the AgInTe2 source targets. Sputtering gas pressure and sputtering power were optimized first and determined as 0.5
Pa and 100 W, respectively. After the deposition, annealing was carried out in ambient N2 for 30 min at temperatures
from 100oC to 350oC. The characterizations of thin films were performed by UV-Vis absorption spectra, XRD and
Hall-effect measurements and fabrication of solar cells. The AgInTe2 sputtered layer found to be so promising for a
bottom cell with significantly low carrier concentration as low as 6.9 × 1011 /cm3 and high mobility 1.2 ×
104/cm2(Vs)-1 at 200oC deposition and annealing temperature. AgInTe2 solar cells were fabricated as
AgInTe2/In2S3/TiO2/FTO structure with Au electrode. As a primary cell results conversion efficiency of 1.13% was
achieved with Voc of 232 mV, Jsc of 13.6 mA/cm2 with 35.6 FF. Additionally, doping of AgInTe2 by metals including
Al, Ni, Cu and Zn was also also carried out and analyzed after sputtering. High quality p-type AIT obtained by Zn
doping with carrier density of 2.14×1013 /cm3 and mobility of 3.87×104 /cm2(Vs)-1 where best n-type AIT could be
achieved by Ni doping with carrier density of -6.51×1011 /cm3 and mobility of 8.53×104 /cm2(Vs)-1.
Derivation of instanton rate theory from first principles

description: Instanton rate theory is used to study tunneling events in a wide range of systems including low-temperature chemical reactions. Despite many successful applications, the method has never been obtained from first principles, relying instead on the "ImF" premise. In this paper, the same expression for the rate of barrier penetration at finite temperature is rederived from quantum scattering theory [W. H. Miller, S. D. Schwartz, and J. W. Tromp, J. Chem. Phys. 79, 4889 (1983)] using a semiclassical Green's function formalism. This justifies the instanton approach and provides a route to deriving the rate of other processes.

description: We report on broadband X-ray properties of the Rabbit pulsar wind nebula (PWN) associated with the pulsar PSR J1418-6058 using archival Chandra and XMM-Newton data, and a new NuSTAR observation. NuSTAR data above 10 keV allowed us to detect the 110-ms spin period of the pulsar, characterize its hard X-ray pulse profile, and resolve hard X-ray emission from the PWN after removing contamination from the pulsar and other overlapping point sources. The extended PWN was detected up to $\sim$20 keV and is well described by a power-law model with a photon index $Γ\approx$2. The PWN shape does not vary significantly with energy, and its X-ray spectrum shows no clear evidence of softening away from the pulsar. We modeled the spatial profile of X-ray spectra and broadband spectral energy distribution in the radio to TeV band to infer the physical properties of the PWN. We found that a model with low magnetic field strength ($B\sim 10$ $μ$G) and efficient diffusion ($D\sim 10^{27}$ cm$^2$ s$^{-1}$) fits the PWN data well. The extended hard X-ray and TeV emission, associated respectively with synchrotron radiation and inverse Compton scattering by relativistic electrons, suggests that particles are accelerated to very high energies ($\gtrsim500$ TeV), indicating that the Rabbit PWN is a Galactic PeVatron candidate.

description: We study if the parabolic forward-in-time maximal operator is bounded on parabolic BMO. It turns out that for non-negative functions the answer is positive, but the behaviour of sign changing functions is more delicate. The class parabolic BMO and the forward-in-time maximal operator originate from the regularity theory of nonlinear parabolic partial differential equations. In addition to that context, we also study the question in dimension one.
