description: InAs quantum dots (QDs) on GaAsSb barriers with delta-doping levels (0, 2, 4, and 6 electrons per dot
(e/dot)) and different Sb compositions (8, 13 and 15 %) have been studied. Photoluminescence (PL) spectra of the 4
e/dot sample exhibits additional energy peak which is attributable to emission from the first excited states of the QDs.
On the contrary, this peak is not shown in PL spectra of un-doped sample. The thermal activation energies for
heavily doped samples, the 4 and 6 e/dot samples, were greater than those for lightly doped samples, the 0 and 2
e/dot samples. This increased thermal activation energy is attributed to the enhancement of Columbic interaction in
the InAs QD area introducing the delta-doping planes. This is also supported by temperature dependent time resolved
PL (TRPL) data. Additionally, the InAs/GaAsSb QD samples with 8, 13 and 15 % Sb compositions nearby the
crossover from a type I to II band alignment show different peak shift behaviors with excitation power increases.
Since the PL peak position of the 8 and 13 % Sb samples did not shift while that of the 15 % Sb sample was blueshifted
with increasing excitation power it is concluded that InAs QDs embedded in GaAs0.86Sb0.14 would have
almost flat valence band offset. TRPL data also show that 15 % Sb sample has a much longer carrier lifetime
compared to that of 8 % and 13 % Sb sample, meaning that the transformation from a type I to II band alignment
occurs between 13 % and 15 % Sb composition.

description: Quantum repeaters based on heralded entanglement require quantum nodes that are able to generate multimode quantum correlations between memories and telecommunication photons. The communication rate scales linearly with the number of modes, yet highly multimode quantum storage remains challenging. In this work, we demonstrate an atomic frequency comb quantum memory with a time-domain mode capacity of 1250 modes and a bandwidth of 100 MHz, to our knowledge the largest number of modes stored in the quantum regime. The memory is based on a $Y_{2}SiO_{5}$ crystal doped with $^{171}Yb^{3+}$ ions, with a memory wavelength of 979 nm. The memory is interfaced with a source of non-degenerate photon pairs at 979 and 1550 nm, bandwidth-matched to the quantum memory. We obtain strong non-classical second-order cross correlations over all modes, for storage times of up to $25$ $μs$. The telecommunication photons propagated through 5 km of fiber before the release of the memory photons, a key capability for quantum repeaters based on heralded entanglement and feed-forward operations. Building on this experiment should allow distribution of entanglement between remote quantum nodes, with enhanced rates owing to the high multimode capacity.

description: We consider next generation solar cells concepts those that have the potential to exceed the limiting
efficiency calculated by Shockley and Queisser for single gap solar cells (40.7 %) and still have not been
commercialized. Among these concepts, this paper deals with the multiple exciton generation (or impact ionization
or multiple carrier generation) solar cell, the intermediate band solar cell and the hot carrier solar cell. These concepts
were proposed theoretically more than ten years ago. In the last years, the number of experiments supporting the
theories behind and paving the way towards their practical implementation has leaped forward. This work reviews
these experimental advances.

description: A method for shaping the angular divergence at sun simulators is presented. The method is applied to a
sun simulator for concentrator modules which use one light source. Diffuse reflectors with different radial symmetric
patterns are used to simulate different levels of circumsolar ratios. The impact of the simulated circumsolar radiation
is shown for two different photovoltaic concentrator modules. One module is equipped with reflective secondary
optical elements while the other is equally manufactured but without secondary. The module with the secondaries
showed a better angular transmission, especially for angles between 0.5° and 2.0°. When the angular divergence at a
sun simulator is shaped in order to simulate higher ratios of circumsolar radiation, the efficiency of both modules are
found to decrease. However, the relative performance loss of the secondary module is several percent lower than this
of the module without secondaries

description: The paper describes the unique geometric properties of ideal magnetohydrodynamics (MHD), and demonstrates how such features are inherited by extended MHD, viz. models that incorporate two-fluid effects (the Hall term and electron inertia). The generalized helicities, and other geometric expressions for these models are presented in a topological context, emphasizing their universal facets. Some of the results presented include: the generalized Kelvin circulation theorems; the existence of two Lie-dragged 2-forms; and two concomitant helicities that can be studied via the Jones polynomial, which is widely utilized in Chern-Simons theory. The ensuing commonality is traced to the existence of an underlying Hamiltonian structure for all the extended MHD models, exemplified by the presence of a unique noncanonical Poisson bracket, and its associated energy.

description: Advanced light management in thin-film solar cells is becoming increasingly important to reduce
semiconductor layer thicknesses (and thus costs) while still absorbing the full solar spectrum in the cell. Here, we
discuss how the excitation of surface plasmon resonances in metal nanoparticles can serve to enhance the trapping of
light in thin-film solar cells. We discuss three geometries, with particles either at the top or back of the cell, or
embedded in the solar cell, and compare these different designs. We demonstrate the effectiveness of the plasmonic
light trapping concept by presenting experimental data on ultra-thin n-i-p a-Si:H solar cells with plasmonic back
reflectors. We show that using a properly designed scattering structure, the performance of cells on randomly
textured Asahi substrates can be surpassed. The periodic patterns are made via an inexpensive and scalable
nanoimprint method. Electromagnetic modeling is shown to agree well with measurements, and used to understand
further details of the device.

description: Scattered light from the Earth and Moon can significantly impact the background levels in TESS full frame images (FFIs), hindering the search for transiting exoplanets and other astronomical phenomena. While scattered light is often corrected at the light curve level, we present a novel approach to model and remove scattered light at the image level using deep learning. We have developed a conditional diffusion model that accurately captures the scattered light patterns in FFIs probabilistically, using only the angles and distances of the Earth and Moon with respect to the TESS cameras. The model learns the complex, dynamic patterns of scattered light and produces corrected FFIs along with uncertainties. By removing scattered light at the image level, we can enable improved photometry and planet searches in scattered light-affected regions of the FFIs. We demonstrate the performance of our model on all TESS sectors. This deep learning approach has the potential to revolutionize scattered light and systematic corrections in present and future space-based telescopes.

description: We report the results of an in-depth study of the role of graph topology on quantum transport efficiency in random removal and Watts-Strogatz networks. By using four different environmental models -- noiseless, driving by classical random telegraph noise (RTN), thermal quantum bath, and bath+RTN -- we compare the role of the environment and of the change in network topology in determining the quantum transport efficiency. We find that small and specific changes in network topology is more effective in causing large change in efficiency compared to that achievable by environmental manipulations for both network classes. Furthermore, we have found that noise dependence of transport efficiency in these networks can be categorized into six classes. In general, our results highlight the interplay that network topology and environment models play in quantum transport, and pave the way for transport studies for networks of increasing size and complexity -- when going beyond so far often used few-site transport systems.

In this paper, we consider when ladder graphs are prime and when the corresponding labeling may be done in a cyclic manner around the vertices of the ladder. Furthermore, we discuss coprime labelings for complete bipartite graphs.

description: We derive positivity bounds for scattering amplitudes of particles with arbitrary spin using unitarity, analyticity and crossing symmetry. The bounds imply the positivity of certain low-energy coefficients of the effective action that controls the dynamics of the light degrees of freedom. We show that low-energy amplitudes strictly softer than $O(p^4)$ do not admit unitary ultraviolet completions unless the theory is free. This enforces a bound on the energy growth of scattering amplitudes in the region of validity of the effective theory. We discuss explicit examples including the Goldstino from spontaneous supersymmetry breaking, and the theory of a spin-1/2 fermion with a shift symmetry.

description: This paper describes the details of the new multi-technology ground-mounted photovoltaic (PV) field
installed at the Airport of Bolzano Dolomiti (ABD) in the Italian Alps. The plant, owned by ABD and developed
with a co-financing of the European Regional Development Fund (ERDF), is divided into two main parts: a 662 kW
commercial installation, mounting 8538 CdTe modules First Solar 277, and a 62 kW experimental installation,
mounting 24 different types of modules, divided into 39 groups ranging between 1 and 2 kW each. In this
experimental installation the modules are mounted on fixed racks, as well as on mono-axial and bi-axial active
trackers. EURAC Research is the scientific responsible of this test facility and follows the monitoring and test
activities to evaluate the performance and the lifetime degradation of the modules. The aim of the monitoring activity
is to allow a better understanding of module loss mechanisms for each technology and evaluating the performance in
the alpine climatic conditions. The PV modules are evaluated in relationship to meteo data from an on-site station,
counting a sensor for ambient temperature, an anemometer, a pyrheliometer, three pyranometers, an albedometer and
also a sun photometer which allows evaluating the influence given by aerosols, ozone and vapors in the atmosphere
to the irradiance. PV reference cells are also used, mounted horizontally, on the module plane, and on the two
trackers. The PV plant has been connected to the MV network on August 10, 2010, and it is presently in course of
approval by GSE (Gestore Servizi Energetici) for the incentive scheme in force. Monitoring results can be presently
shown only for a couple of days for a limited number of groups.

description: In this paper we present an alternative to our metal-wrap-through “PUM” metallization concept that simplifies the cell process and thereby reduces manufacturing costs. The simplified printing step allows complete filling of the holes with a specially designed conductive paste. With this “plug” concept of closed PUM holes we achieved a feasible, more stable process, performing better than the reference PUM process by showing an absolute increase of 0.2% in efficiency. In this form, the PUM process showed to be industrially feasible. The implementationof the plug metallization in the ASPIRe cell concept was successful as well. The first “plug” ASPIRe cells performed as well as expected from the PUM results, showing a maximum efficiency of 15.9%.

description: In this paper, we focus on a new wave equation described wave propagation in the attenuation medium. In the first part of this paper, based on the time-domain space fractional wave equation, we formulate the frequency-domain equation named as fractional Helmholtz equation. According to the physical interpretations, this new model could be divided into two separate models: loss-dominated model and dispersion-dominated model. For the loss-dominated model (it is an integer- and fractional-order mixed elliptic equation), a well-posedness theory has been established and the Lipschitz continuity of the scattering field with respect to the scatterer has also been established.Because the complexity of the dispersion-dominated model (it is an integer- and fractional-order mixed elliptic system), we only provide a well-posedness result for sufficiently small wavenumber. In the second part of this paper, we generalize the Bayesian inverse theory in infinite-dimension to allow a part of the noise depends on the target function (the function needs to be estimated). Then, we prove that the estimated function tends to be the true function if both the model reduction error and the white noise vanish. At last, our theory has been applied to the loss-dominated model with absorbing boundary condition.

description: Selective emitter is one of the attractive possibilities how to achieve better electrical parameters of crystalline silicon solar cells. In this paper we present an innovative process for high efficient solar cells based on the screen-printable etching paste for a diffusion barrier (SiOx or SiNx) and subsequent heavy phosphorus diffusion into the open area for otherwise state of the art equipment and technology. With this easy, fast and environmentally friendly additional step(s) final solar cell efficiency close to 17 % (for standard 5 inch p-type CZ silicon) has been reached which is the value increased by 0.7 % (absolute) compared to the cells with a standard homogeneous emitter.

description: It is common knowledge that paste rheology is greatly influenced by temperature. In general, a higher temperature will lower the viscosity of Thick Film paste. Screen printing is the most common method of transferring silver Thick Film paste to a silicon wafer to create a Solar Cell. Presumably, Thick Film paste with varying rheology will have a varying print quality. However, there have been no studies to validate this theory or show to what degree this is or isn’t true. Line quality plays a large factor in electrical performance of a Solar Cell. Uneven and/or broken finger lines will cause higher line resistance. Lines with too much slumping will cause optical losses and also cause a higher line resistance. These factors can be controlled by proper printing. It is important to understand the extent temperature has in effecting rheology, print quality and electrical performance. This paper will examine the effects temperature has on these parameters.
Printing parameters such as pressure, downstop, snap off, speed and squeegee hardness were controlled to eliminate variation from the printer. One screen was used and the wafers were all similar in minority carrier lifetime. One experimental paste was made and a rheology study was performed. Flowcurves on a cone and plate measuring system were generated at 20ºC, 25ºC and 30ºC with a constant speed. A temperature sweep was then performed plotting viscosity points between 15ºC and 35ºC. The paste was then split into three containers and stored at 20ºC, 25ºC and 30ºC. The printing screen and wafers were also stored at these temperatures to simulate a real room temperature shift. The screen printer was set up with the controlled parameters and each paste was printed on three wafers before temperature was able to fluctuate. Wafers were then measured for aspect ratio at wet, dried and fired stages. Aspect ratio data was recorded. Once fired, wafers are ready to be tested for electrical performance. The focus of the electrical performance will be on Line Resistance.

description: Extreme Emission Line Galaxies (EELGs) are characterized by their compact sizes and very high equivalent widths of certain optical emission lines (e.g. EW([OIII]) > 500a), indicative of very high specific star formation rates, similar to those detected in the reionization epoch galaxies. Many of them also present certain high-excitation emission-lines, such as HeII at 4686a, indicative of a very hard incident stellar radiation. We compiled from SDSS the largest (around 2000) sample of EELGs using an automatic algorithm and we studied their physical properties and chemical abundances from the direct method. This allowed us to study the fundamental relations followed by this type of galaxies (e.g MZR, MNOR, O/H-N/O). This observational feedback can be used to constrain photoionization models from which we can provide model-based solutions to derive the properties of the high-z galaxies using only their available observed strong emission-lines. Among the model-based solutions that benefit from this constrains and can be subsequently applied to high-z EELGs are the HII-CHI-mistry code. We will show that this code can be adapted to give specific solutions to derive chemical abundances.

description: At IMEC the i-PERC concept of thermally fired local back-surface field (LBSF) cells, was developed to improve the rear surface passivation over full Al-BSF cells in order to be able to realize thinner and thinner bulk silicon solar cells without sacrificing efficiency. For the first time, the i-PERC concept has been applied using high quality float zone silicon. This industrial rear side process is combined with a lab-scale front side process, consisting of a lithography process and metal evaporation to define the front finger grid. Small area (4 cm2) i-PERC cells are compared with solar cells having a standard aluminum back surface field. Both silicon nitride and thermal silicon oxide are investigated to passivate the front surface. Comparing a standard Al BSF with the i-PERC process, shows a clear increase in open-circuit voltage of around 8 to 10 mV and an increase in short-circuit current density of approximately 1 mA/cm2, leading to a gain in energy conversion efficiency of 0.8 percent absolute.

description: Recently, some eccentricity-invariant properties of random, isotropic, two-dimensional (2D) systems of conductive ellipses have been reported [Phys. Rev. B \bf{104}, 184205 (2021)]. Moreover, the authors suggested that this invariance might also be observed in systems with other particle geometries having zero-width sticks as the limiting case. To check this suggestion, we studied 2D random systems of isotropically-placed, overlapping, identical discorectangles (stadia) with aspect ratios ranging from 1 (disks) to $\infty$ (zero-width sticks). We analyzed the effect of the aspect ratio and the number density of conductive discorectangles on the behavior of the electrical conductivity, the local conductivity exponent, and the current-carrying backbone. Our own computer simulations demonstrate that some of the properties of random, isotropic 2D systems of conductive discorectangles are insensitive to the aspect ratios of the particles.

description: Plasma inline systems provide a great potential concerning high throughput and multi-purpose processes. The combination of wafer conditioning and subsequent a-Si:H deposition is a further approach to upgrade the process flow of solar cells. Within this work, a modified inline plasma system manufactured by Roth&Rau (SiNA) was used to implement both wafer conditioning and a-Si:H deposition within the same vacuum chamber. The deposition of amorphous silicon as well as the etching steps have been evaluated and combined. Effective excess carrier lifetime of more than 700 μs (FZ-Si, p-type, 1 Ωcm) could be achieved. The investigated process can be adapted to fit in the workflow for PERC-type (passivated emitter and rear cell) high efficiency solar cell structures.

description: Reliable quantitative relations between the annual energy yield of PV systems at a specific site and the
PV module parameters declared in the data sheet, which are generally measured indoors under STC, have been
established and the relevant parameters for characterization of annual module and system energy yield have been
determined. The implementation of best practices in the outdoor testing community has considerably increased the

Probing Parity-Violation with the Four-Point Correlation Function of BOSS Galaxies

description: Parity-violating physics in the early Universe can leave detectable traces in late-time observables. Whilst vector- and tensor-type parity-violation can be observed in the $B$-modes of the cosmic microwave background, scalar-type signatures are visible only in the four-point correlation function (4PCF) and beyond. This work presents a blind test for parity-violation in the 4PCF of the BOSS CMASS sample, considering galaxy separations in the range $[20,160]h^{-1}\mathrm{Mpc}$. The parity-odd 4PCF contains no contributions from standard $Λ$CDM physics and can be efficiently measured using recently developed estimators. Data are analyzed using both a non-parametric rank test (comparing the BOSS 4PCFs to those of realistic simulations) and a compressed $χ^2$ analysis, with the former avoiding the assumption of a Gaussian likelihood. These find similar results, with the rank test giving a detection probability of $99.6\%$ ($2.9σ$). This provides significant evidence for parity-violation, either from cosmological sources or systematics. We perform a number of systematic tests: although these do not reveal any observational artefacts, we cannot exclude the possibility that our detection is caused by the simulations not faithfully representing the statistical properties of the BOSS data. Our measurements can be used to constrain physical models of parity-violation. As an example, we consider a coupling between the inflaton and a $U(1)$ gauge field and place bounds on the latter's energy density, which are several orders of magnitude stronger than those previously reported. Upcoming probes such as DESI and Euclid will reveal whether our detection of parity-violation is due to new physics, and strengthen the bounds on a variety of models.

Large Tunable Thermophase in Superconductor -- Quantum Dot -- Superconductor Josephson Junctions

description: In spite of extended efforts, detecting thermoelectric effects in superconductors have proven to be a challenging task, due to the inherent superconducting particle-hole symmetry. Here we present a theoretical study of an experimentally attainable Superconductor -- Quantum Dot -- Superconductor (SC-QD-SC) Josephson Junction with highly tunable thermoelectric properties and a thermal response that is far larger than previous suggestions. The QD energy level between the SCs breaks particle-hole symmetry in a gradual manner, allowing, in the presence of a temperature gradient, for gate controlled appearance of a superconducting thermo-phase. This thermo-phase increases up to a maximal value of $π/2$ after which thermovoltage is expected to develop. Using time-independent Keldysh countour Green's functions we derive the exact thermo-phase and thermal response on the junction. These are shown to be orders of magnitude larger than usual SC tunnel junctions with a sharp dependence on gate voltage.

Haugianere i Amerika

description: In this article, we discuss the push and pull factors for Haugeans to join the first, organized emigration from Norway to America in 1825. The Haugeans represented early revival Christianity with the personal, religious choice, and responsibility for their own lives and future both here and beyond. The social relations were lifted out of the traditional, steadfast class society, and were reorganized and linked to the society of friends. The Haugeans’ training in social mobility is an important prerequisite for emigration. We look into the development of Haugeanism in the Norwegian settlements, from the first, vital role of the Haugean preachers to the gradual institutionalization in the late 1840s. Both synods and colleges bore Hans Nielsen Hauge’s name in America. The Haugean synods gradually became more marginalized towards the turn of the 19th century, as most Norwegian-Americans chose to join other Norwegian synods. Hans Nielsen Hauge nevertheless retained a central place in the Norwegian-American consciousness.

description: Production of thin film solar cells is growing worldwide. Recently, Cu(In,Ga)S,Se2 (CIS or CIGS)
received more and more attention. This contribution tries to analyze the success story of CIGS based solar cells
and the potential of this technology for future PV large scale production. Specific material properties make CIS
unique and allow the preparation of the material with a wide range of processing options. The big potential lies in
the possibility to take advantage of modern thin film processing equipment and combine it with very high
efficiencies beyond 20% already achieved on the laboratory scale. A sustainable development of this technology
could be realized by modifying the materials and replacing Indium by cheaper elements.

description: This contribution compares different characterization methods and their suitability to detect mechanical
and electrical defects. Commercially available photovoltaic (PV) modules were tested using different analysis
methods. Some methods are already standard in solar cell inspection like electroluminescence or thermography but
have rarely been expanded to module scale. Other methods like laser-doppler vibrometry or digital image correlation
are used for mechanical purposes and can be used to determine mechanical parameters of PV modules as a mechanical
element. The combination of mechanical and electrical analysis methods allows a very precise assessment of the
mechanical and electrical condition which is essential for reliability and lifetime concepts. Also an understanding of
many effects and their causes is possible and can be used for module layout improvement.
Because micro-cracks caused by mechanical or thermal loading are a serious problem in crystalline PV modules, the
mechanisms of this specific defect type should be investigated. For this purpose laminated test specimens on smaller
scales were produced and analyzed over production process and during temperature cycles derived from the international
standards IEC 61215 and IEC 61646. The analysis was done by electroluminescence imaging and the crack
development was evaluated statistically. The results are presented and are compared to results from numerical simulations.
