description: Cu(In,Ga)Se2 (CIGS) continuously demonstrates more of its potential with cell efficiencies exceeding
22% on laboratory scale. A goal for the future is the reduction of the absorber thickness. In the past a phototransistor
model was introduced to explain the cell behavior for low temperatures or after long term endurance test. This
phototransistor model depends on a back contact barrier which becomes more important for a reduced thickness or low
doping densities of the absorber. In this contribution the occurrence of a punch-through effect during long term
endurance test with an applied negative bias is discussed. In the field negative voltages could occur due to partial
shading. From transistor theory the punch-through effect is well known. If the space charge region of the Schottky
barrier and the main junction touch, a punch-through occurs resulting in a strong increase of the current and a
significantly reduced open circuit voltage. A reduced doping density of the absorber or/and an increased barrier at the
back contact enhance this behavior. This assumption is verified with simulations based on the phototransistor model.
Finally, the influence on highly efficient cells with reduced absorber thickness is discussed. For thick absorbers this
phenomena should play no role under normal operating conditions. But for a reduced absorber thickness the punchthrough
effect can occur in the initial state and have a negative influence on the cell performance for cells with thinner
absorbers. If the trend towards reduced absorber thicknesses in the future continues, further investigations regarding
the back contact barrier including the adjustment of the doping density are necessary.

description: We study the evolution of black hole entropy and temperature in collapse scenarios, finding three generic lessons. First, entropy evolution is extensive. Second, at large times, entropy and temperature ring with twice the frequency of the lowest quasinormal mode. Third, the entropy oscillations saturate black hole area theorems in general relativity. The first two features are characteristic of entanglement dynamics in `democratic' models. Solely based on general relativity and Bekenstein-Hawking entropy formula, our results point to democratic models as microscopic theories of black holes. The third feature can be taken as a prediction for democratic models coming from black hole physics.

description: The diffusion or transport length (L) of photo-generated charge carriers has been measured directly in
CH3NH3PbI3 powders by applying the surface photovoltage (SPV) method after Goodman. The average size of
crystallites in the powder was changed between tens of μm and about 1 mm. The values of L ranged between 3 and
30 μm and decreased to 0.6 μm in some cases after light soaking. It was shown that light soaking does not necessarily
lead to a degradation of L. An instability of L was observed under certain conditions depending on conditioning of
CH3NH3PbI3 crystallites, the value of the constant SPV signal and light soaking. The results have consequences for
the further development of solar cells based on CH3NH3PbI3.

description: Comparison of échelle spectra to synthetic models has become a computational statistics challenge, with over ten thousand individual spectral lines affecting a typical cool star échelle spectrum. Telluric artifacts, imperfect line lists, inexact continuum placement, and inflexible models frustrate the scientific promise of these information-rich datasets. Here we debut a scalable machine-learning framework "blasé" that addresses these challenges. The semi-empirical approach can be viewed as "transfer learning"--first pre-training models on noise-free precomputed synthetic spectral models, then learning the corrections to line depths and widths from noisy whole-spectrum fitting. The auto-differentiable model employs back-propagation, the fundamental algorithm empowering modern Neural Networks. Here, however, the 40,000+ parameters symbolize physically interpretable line profile properties (amplitude, width, location, shape) plus RV and vsini, rather than difficult-to-interpret neural network "weights". This hybrid data-/model- driven framework allows joint modeling of stellar and telluric lines simultaneously, a potentially transformative step forwards for pesky telluric mitigation in the near-infrared. Blasé also acts as a deconvolution tool. It is suitable for Doppler Imaging scenarios with longitudinally symmetric surface features like bands or polar spots, which evade detection in differential techniques. Blasé can also create super-resolution semi-empirical templates useful for critically evaluating atomic and molecular line lists. Its sparse-matrix architecture and GPU-acceleration make blasé fast, with end-to-end training of 50+ échelle orders in under 1 minute. The open-source PyTorch-based code (blase.readthedocs.io) includes tutorials and API documentation. We show how the tool fits into the existing Python spectroscopy ecosystem, demonstrate a range of astrophysical applications, and discuss limitations and future extensions.

description: Monolithic interconnection of thin film solar cells is an essential step of PV module development. So
far, monolithic interconnection using laser scribes has been established as a favoured method for silicon thin film
solar cells deposited on glass substrates. Transferring this method to flexible substrates is an important key for
industrial realisation of an efficient module concept. In this work, we demonstrate the feasibility of monolithic
interconnection of micromorph silicon tandem thin film solar cells deposited on flexible aluminium substrates by
applying the interconnection on one cell stripe using laser scribes. Fabrication problems concerning the adhesion of
the back contact and the microcrystalline bottom cell were solved by plasma treatment. For the P2 and P3 scribe the
laser parameters were adjusted in order to ablate the thick layer stack successfully. In case of the P3 scribe, a
modified ablation method was used to avoid melting of the layers which predominantly occurred. As final result we
demonstrate a well working monolithic interconnection concept of micromorph tandem solar cells on aluminium
substrates without significant electrical losses compared to a non interconnected reference cell. Furthermore, our
optimised parameters for all scribes are presented.

description: The recent demonstration of resonant tunneling transport in nitride semiconductors has led to an invigorated effort to harness this quantum transport regime for practical applications. In polar semiconductors, however, the interplay between fixed polarization charges and mobile free carriers leads to asymmetric transport characteristics. Here, we investigate the possibility of using degenerately doped contact layers to screen the built-in polarization fields and recover symmetric resonant injection. Thanks to a high doping density, negative differential conductance is observed under both bias polarities of GaN/AlN resonant tunneling diodes (RTDs). Moreover, our analytical model reveals a lower bound for the minimum resonant-tunneling voltage achieved via uniform doping, owing to the dopant solubility limit. Charge storage dynamics is also studied by impedance measurements, showing that at close-to-equilibrium conditions, polar RTDs behave effectively as parallel-plate capacitors. These mechanisms are completely reproduced by our analytical model, providing a theoretical framework useful in the design and analysis of polar resonant-tunneling devices.

description: A multiple junction device based on hydrogenated amorphous silicon (a-Si) and microcrystallineamorphous
(μ-Si) mixed phase material has the advantage to reach an high Voc. One of the most important point for
the development of a multiple junctions device is to find the correct balance between the sub-cells current because
this is the limiting factor to the total device output. Because of the a-Si Staebler-Wronski degradation the sub-cell
currents can vary hence, for better cell performance, it is fundamental to balance currents after the light exposure. We
developed a method to measure the intrinsic performance of mj-device to define the correct balance among the cells
leading to a higher device stability in time. In the specific case of a tandem cell, the correct balance determination
allows to avoid also to waste material thanks to the possibility to well define the thickness of each layer. In this work
we studied the impact of current density of μ-Si sub-cell with the aim of reaching the higher efficiency with lower
light induced degradation (LID) factor. Actually we measured an initial efficiency between 12% and 13% on small
area samples and after LID we found values around 11.5% reaching a LID factor of about 9%.

description: Exact multicentered solutions to the governing equations of the Born--Infeld nonlinear theory of electrodynamics describing distributions of electric, magnetic, and dyonic point charge sources are constructed explicitly for the first time. The method of construction may effectively be adapted to obtain such solutions in generalized theories as well. As a consequence, the solutions unveil that, in order to achieve a balance between such multicentered electric or magnetic point charge distribution in equilibrium, a static magnetic or electric current must be present, resulting in non-conservativeness of the induced electric or magnetic intensity field, respectively and universally. Moreover, it is also shown that the methods of construction and conclusions drawn in the multicentered situation may be extended to obtain exact solutions and similar conclusions, explicitly, in the situation of continuously distributed charge source problems.

description: The mechanical properties and the failure of silicon wafers are defined by surface defects, like cracks.
In the wire sawing process different wire types and particle sizes as well as the machine settings affects the quality of
the wafer surface. In order to optimize wire sawing technologies the influence of the crystallographic orientation on
the strength and crack distribution of silicon wafers is investigated in this work. By ball-on-ring-tests the fracture
strength of different orientations was determined and compared to the crack distribution, which was investigated by
bevel polished method. The results show that a rotation of the silicon crystal by 45° (<110> direction) leads to an
increase of the crack density in the surface of the samples and a decrease in the fracture strength of the wafers in
comparisons to the standard sawing orientation (<100> direction).

description: The permanent demand on the improvement of solar cell efficiency and reduction of production costs
has placed much focus on the multiple Cz-crystal pulling technique from one crucible. The use of lower quality
silicon as feedstock for monocrystalline material is not an alternative track because it is in contradiction to the quest
for high cell efficiencies.
PVA Crystal Growing Systems Gmbh has developed a novel mobile recharge system for Czochralski pullers, the
SiCharger MRS. This systems is capable of handling silicon feedstock material up to a chip size of 15 mm and was
extensively tested under industrial conditions. The assignment for a chip size of 40 mm is currently under series of
tests, the results are promising. One MRS-system can serve several pullers, presuming a suitable production
organization. Investment cost and thus amortization period are minimized.
In this paper the MRS-system is presented in detail as well as its operation during the recharging of the hot crucible.
The influence of the different types of feedstock on the recharge process is presented. The segregation effect of
impurities on the quality of multiple ingots grown in one crucible is shown.

description: We report on B2-ordering dependence of magnetostatic surface spin waves in ferromagnetic FeRh at room temperature. Spin waves transmit over a distance longer than 21 μm in highly ordered FeRh alloys even with relatively large spin-orbit interaction. The long-range transmission likely arises from the induced Rh moments of the ordered FeRh due to ferromagnetic exchange interaction between Fe and Rh. The results indicate a potential of using FeRh in spintronic and magnonic applications by integrating with other fascinating magnetic characteristics of FeRh such as electric field induced magnetic phase transition.

description: The resemblance between electrons and optical waves has strongly driven the advancement of mesoscopic physics. However, electron waves have yet to be understood in open cavity structures which have provided contemporary optics with rich insight towards non-Hermitian systems and complex interactions between resonance mode. Here, we report the realization of an open cavity resonator in a two-dimensional electronic system. We studied the resonant electron modes within the cavity and resolved the signatures of longitudinal and transverse quantization, showing that the modes are robust despite the openness of the cavity being highly open to the background continuum. The transverse modes were investigated by applying a controlled deformation to the cavity, and their spatial distributions were further analyzed using magnetoconductance measurements and numerical simulation. These results lay the groundwork to exploring electronic wavefunctions in the context of modern optical systems, such as the dielectric microcavity.

description: The breakage of thin Silicon (Si) wafers is a significant problem that leads to lower production yields
in the manufacture of Si-based solar cells. Residual stress of Si wafers is therefore a major concern due to its
detrimental effect on wafer mechanical integrity. This work investigates the spatial distribution of residual stress in
multicrystalline silicon (mc-Si) wafers produced by the two prevalent wire sawing methods used in industry: loose
abrasive slurry wire sawing (LAWS) and fixed abrasive diamond wire sawing (DWS). The saw damage layer of ascut
industrially sawn DWS and LAWS wafers was removed at 2 μm steps using wet chemical isotropic etching and
residual stress was measured as a function of etch depth using a near-infrared birefringence polariscope. Results show
that in as-cut wafers, DWS creates a larger number of high maximum residual shear stress locations compared to
LAWS. In DWS, points of highest residual stress were aligned with wire striation lines in the direction of wire travel.
In contrast, LAWS resulted in a random pattern of locations of high residual stress. After 12 μm of material removal
by etching, the points of highest residual stress were localized at grain boundaries in both DWS and LAWS wafers.

The study of magnetic moments in nuclei far away from the stability line is the next frontier in such studies. Two techniques have been utilized to populated low-spin states in radioactive nuclei: coulomb excitation reactions using radioactive nuclei, and the transfer of $α$ particles to stable beams to populate low spin states in radioactive nuclei. A presentations of these two techniques, along with the experimental challenges presented for future uses with nuclei far away from the stability line, will be presented.

description: How to improve short circuit current of CdTe solar cells while maintaining high open circuit voltage
and fill factor is a key point to achieve high efficiency. In this paper, we used homely designed vapor transport
deposition system to prepare CdTe films and proposed a solar cell structure which can lead to 16.28% efficiency solar
cell with wide spectral response. The property of CdTe films were optimized by VTD parameters in details.
Appropriate high substrate temperature is very important to prepare CdTe films with larger grain size, higher hole
density, lower resistivity and better crystallinity. The solar cell deposited at 610 shows the best conversion
efficiency. CdS thickness has obvious influence on the spectral response of CdTe solar cells in short wavelength
region. The quadra like spectral response was obtained by using 30nm CdS window layer, while the device efficiency
is less than 10%. After a high resistive buffer layer is inserted between TCO and CdS, the solar efficiency apparently
increased up to 16.28%. This CdTe solar cell has a better spectral response than that from GE and NREL and nearly
the same response with that from First Solar in short wavelength region. This suggests that CdTe solar cell with the
structure of very thin CdS and buffer layer can reach a high efficiency with wide spectral response. A higher
efficiency for CdTe solar cell can be expected by using this structure.

description: Cloud-native architectures are often based on microservices and combine different aspects that aim to leverage the capabilities of cloud platforms for software development. Cloud-native architectural characteristics like patterns and best practices aim to design, develop, deploy, and operate such systems efficiently with minimal time and effort. However, architects and developers are faced with the challenge of applying such characteristics in a targeted manner to improve selected quality attributes. Hence, we aim to investigate relationships, or more specifically impacts, between architectural characteristics of cloud-native applications, and quality aspects. The architectural characteristics in consideration are based on our recently proposed quality model for cloud-native software architectures. To validate its elements and revise this literature-based quality model, we conducted a questionnaire-based survey among 42 software professionals. While the survey results reinforce the quality model to a fair extent, they also indicate parts requiring a revision. Thus, as an additional contribution, we present an updated version of the quality model incorporating the survey results. Practitioners will benefit from our work when designing and developing cloud-native applications in a quality-oriented way. Researchers will moreover profit from our specifically developed questionnaire-based survey tool, which allows surveying complex structures like a hierarchical quality model.

wafers with favorable surface and subsurface characteristics is using diamond wires made with different grit shapes.
In this paper, we study mono-crystalline silicon wafers cut by wires with two nominally different grit shapes (denoted
A and B), to determine the effect of grit shape on the wafer surface morphology, roughness, subsurface damage, and
fracture strength. It is found that the surface morphology of wafers cut by wire A exhibits more ductile grooves while
the wafer surface cut by wire B exhibits more brittle fracture. The surface roughness data show that wafers cut by
wire A have lower surface roughness than those cut by wire B. However, biaxial flexure tests on laser-cut wafer
coupons show that the wafers cut by wire A have lower fracture strength than those cut by wire B. The subsurface
damage in wafers cut by wire A consists of fewer but longer median cracks than those cut by wire B, which has
shallow median and lateral cracks. We hypothesize that the observed variation in fracture strength results from the
dominance of the subsurface condition over the surface condition.

description: We have performed magnetic susceptibility, magnetization, and specific heat measurements on a chiral magnet GdNi$_3$Ga$_9$, belonging to the trigonal space group $R32$ (\#155). A magnetic phase transition takes place at $T_{\rm N}$ = 19.5 K. By applying a magnetic field along the $a$ axis at 2 K, the magnetization curve exhibits two jumps at $\sim$ 3 kOe and = 45 kOe. To determine the magnetic structure, we performed a resonant X-ray diffraction experiment by utilizing a circularly polarized beam. It is shown that a long-period antiferromagnetic (AFM) helical order is realized at zero field. The Gd spins in the honeycomb layer are coupled in an antiferromagnetic manner in the $c$ plane and rotate with a propagation vector $q$ = (0, 0, 1.485). The period of the helix is 66.7 unit cells ($\sim 180$~nm). In magnetic fields above 3~kOe applied perpendicular to the helical $c$ axis, the AFM helical order changes to an AFM order with $q$ = (0, 0, 1.5).

description: While external language models (LMs) are often incorporated into the decoding stage of automated speech recognition systems, these models usually operate with limited context. Cross utterance information has been shown to be beneficial during second pass re-scoring, however this limits the hypothesis space based on the local information available to the first pass LM. In this work, we investigate the incorporation of long-context transformer LMs for cross-utterance decoding of acoustic models via beam search, and compare against results from n-best rescoring. Results demonstrate that beam search allows for an improved use of cross-utterance context. When evaluating on the long-format dataset AMI, results show a 0.7\% and 0.3\% absolute reduction on dev and test sets compared to the single-utterance setting, with improvements when including up to 500 tokens of prior context. Evaluations are also provided for Tedlium-1 with less significant improvements of around 0.1\% absolute.

description: Wafer slicing by diamond wire saws will substantially contribute to cost reduction in mono c-Si (mcSi)
wafer production provided the coolant supply technology is economically viable. Aqueous (water based) coolants
appear to be generally advantageous. Meanwhile new coolants with more attractive prices can be found on the
market. The ways how to apply a coolant and how to handle spent coolants need to be optimized to achieve further
improvements. “LOW-FLOW” and “HIGH- FLOW” coolant mode, both with or without coolant regeneration and
reuse, should be distinguished. A detailed economic comparison clearly shows that “HIGH-FLOW” coolant usage,
imperatively combined with reclaim of spent coolant, lowers the impact of coolant supply on wafer production costs
significantly. Generally, “HIGH-FLOW” application of aqueous coolants in collaboration with coolant regeneration/
reuse is preferable to any “LOW-FLOW” mode if disadvantages due to continuously increasing solid load during one
cut are tolerable, and if spent coolant is regenerated and reused. Coolant regeneration and reuse are essential
prerequisites for cost-efficient coolant supply regardless of the mode of coolant application. Without regeneration,
even “high-flow” mode is inefficient.

title: Investigation and Analysis of Naturally Occurring Cannabinoids
Creators: name: Daly, Charlett
Publisher: name: University of Kent

description: There has been a recent proliferation of edible consumer products containing Cannabidiol (CBD), which is a closely related molecule to Tetrahydrocannabinol (THC), both of which are found in cannabis plants. It is thought that any products containing CBD are likely to have a calming effect on the consumer without the psychoactive effect's THC tends to induce. Due to this growing market it is becoming increasingly important to establish an analytical method which can quantify these substances and differentiate between them, as THC is a regulated compound. Both CBD and THC can exist in acid form, CBDA and THCA respectively, which make such analyses challenging. A further complication is that certain analytical techniques such as GC, with high temperature at the inlet, can cause decarboxylation of the CBDA/THCA to CBD/THC. In this project, use of NMR to initially identify and then assess purity of compound standards, was then followed up with method development of liquid chromatography - mass spectrometry (LC-MS) and gas chromatography - mass spectrometry (GC-MS) instruments to further identify and then quantify any cannabinoids present. A method was then developed for detecting and quantifying the presence of cannabinoids within foodstuffs labelled as containing CBD using the developed methods. Qualitative results of investigations were consistent between GC-MS and LC-MC instruments suggesting these are reliable, but quantification optimisation on the methods is needed in future. Due to the lower temperatures used in the LC-MS, reducing decarboxylation reactions within the instrument, this allowed for the a more successful method to detect and identify cannabinoids regardless of acid form present to be achieved.

description: The properties of CdTe thin films deposited by metal-organic vapour deposition (MOCVD) on Mocoated
glass substrates are studied with particular interest in the effect of Na. It is shown that for radio frequency
sputtered Mo layers on soda-lime glass substrates the Na content in the metal layer is regulated by the deposition
pressure of the Mo layer itself due to increased porosity of the metal layer. Na diffusion from the glass into the CdTe
layer results in grain enlargements to such extend that film continuity is broken following CdCl2 treatment for both
low and high Na content. When Na is added post-Mo deposition on quartz substrates, the growth of large faceted
grains is observed in the as-deposited stage, increasing by an order of magnitude compared with Na-free layers.
However, following the CdCl2 activation step the average grain size is reduced but still observed to be larger than in
the Na-free case. The CdTe crystal structure is analysed for the different sample combinations and initial device data
suggest a small improvement in open circuit voltage when Na is present.

description: Chemical bath deposited (CBD) zinc oxide (ZnO) as a front contact in Cu(In,Ga)Se2 (CIGS) based solar cells was
recently demonstrated as a possible non-vacuum alternative to the standard transparent conductive oxide (TCO)
deposited by dry processes. In this contribution, our latest CIGS solar cells results with CBD ZnO layers as TCO are
presented. Using non-vacuum CBD ZnO TCO an efficiency of 18.3 % was achieved, approaching the efficiencies
obtained with sputtered bilayer window consisting of undoped and aluminum doped zinc oxide (ZnO/ZnO:Al) TCO.
Details on the implementation of CBD ZnO TCOs on cells grown on glass substrates with cadmium sulfide (CdS)
and zinc sulfide oxide (Zn(O,S)) buffers as well as on cells deposited on flexible polyimide substrates are presented.

description: We put forward nonadiabatic charge pumping as a method for accessing the different charge relaxation rates as well as the relaxation rates of excited orbital states in double-quantum-dot setups, based on extremely size-limited quantum dots and dopant systems. The rates are obtained in a well-separated manner from plateaus, occurring when comparing the steady-state current for reversed driving cycles. This yields a reliable readout independent of any fitting parameters. Importantly, the nonadiabatic pumping spectroscopy essentially exploits the same driving scheme as the operation of these devices generally employs. We provide a detailed analysis of the working principle of the readout scheme as well as of possible errors, thereby demonstrating its broad applicability. The precise knowledge of relaxation rates is highly relevant for the implementation of time-dependently operated devices, such as electron pumps for metrology or qubits in quantum information.

description: Nonlocality is a key feature discriminating quantum and classical physics. Quantum-interference phenomena, such as Young's double slit experiment, are one of the clearest manifestations of nonlocality, recently addressed as $dynamical$ to specify its origin in the quantum equations of motion. It is well known that loss of dynamical nonlocality can occur due to (partial) collapse of the wavefunction due to a measurement, such as which-path detection. However, alternative mechanisms affecting dynamical nonlocality have hardly been considered, although of crucial importance in many schemes for quantum information processing. Here, we present a fundamentally different pathway of losing dynamical nonlocality, demonstrating that the detailed geometry of the detection scheme is crucial to preserve nonlocality. By means of a solid-state quantum-interference experiment we quantify this effect in a diffusive system. We show that interference is not only affected by decoherence, but also by a loss of dynamical nonlocality based on a local reduction of the number of quantum conduction channels of the interferometer. With our measurements and theoretical model we demonstrate that this mechanism is an intrinsic property of quantum dynamics. Understanding the geometrical constraints protecting nonlocality is crucial when designing quantum networks for quantum information processing.
