New Materials and Concepts for Cells and Modules

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 38-41
description: Shingling technology is a promising approach to improve photovoltaic module efficiency and optimize its energy yield, because it allows an increase of module output power without introducing substantial modification in the cell fabrication process and in the module bill of materials (BOM).
In a shingled module, c-Si PV cells are cut in smaller stripes (usually 3 to 6 stripe per cell, according to the layout) called “shingles” and assembled in strings by connecting the front of the leading edge of each shingle to the back of the tail edge of next one, in a similar way to tiles on  a rooftop. Electrically conductive adhesives (ECAs) are typically used to make the shingles interconnection while the bussing ribbons can be attached using ECA as well as traditional soldering.
In this work, we analyze the technological aspects of shingling module production from cell to assembled string, describe the most relevant process steps and provide proof that shingled modules deliver power advantages compared to standard cell-based modules.
Resolution of phage N15 telomeres by its protelomerase enzyme in mammalian cells

description: N15 is a unique coliphage that replicates as a linear plasmid with covalently-closed hairpin telomeres during its prophage stage. Linearity of the N15 plasmid is conferred solely by two elements, which are the phage-encoded telomerase enzyme TelN and its recognition sequence telomerase occupancy site (tos). Due to the functional independence of TelN and tos from other host or phage accessory proteins, they have been used to linearise a wide range of non-N15 DNA both in vitro and in vivo of Escherichia coli. Furthermore, linear vectors generated by TelN and tos can shuttle mammalian transgenes into eukaryotic cells to facilitate their correct expression in vivo. Based on these findings, it is hypothesised that the TelN-tos system of phage N15 will be functional when expressed in eukaryotic hosts. Hence this study aimed to test this hypothesis by evaluating the properties of the TelN-tos system, and in particular examine the linearisation of DNA containing a tos site by TelN in mammalian cells. By transiently delivering circular tos-containing DNA into TelN-expressing HeLa cells, resolution of the substrate DNA into its linear form was observed in vivo. When the same tos-DNA was incubated with total proteins extracted from TelN-expressing HeLa cells in vitro, linearisation of the tos-DNA was also detected. Hence the hypothesis that TelN-tos will be functional when expressed in mammalian cells is supported, as indicated by TelN’s cleavage activity on tos site in mammalian environment. These results demonstrate the functionality of TelN-tos system in eukaryotic cells for the first time, and can potentially drive the development of a novel DNA linearisation tool for mammalian research, with applications ranging from generation of linear vector systems to artificially inducing chromosomal breakpoints.

description: Beyond iron, a small fraction of the total abundances in the Solar System is made of proton-rich isotopes, the p nuclei. The clear understanding of their production is a fundamental challenge for nuclear astrophysics. The p nuclei constrain the nucleosynthesis in core-collapse and thermonuclear supernovae. The $γ$ process is the most established scenario for the production of the p nuclei, which are produced via different photodisintegration paths starting on heavier nuclei. A large effort from nuclear physics is needed to access the relevant nuclear reaction rates far from the valley of stability. This review describes the production of the heavy proton-rich isotopes by the $γ$ process in stars, and explores the state of the art of experimental nuclear physics to provide nuclear data for stellar nucleosynthesis.

The role of SDG8i from the resurrection grass Sporobolus stapfianus in ectopic expression system of Arabidopsis
Creators: name: Islam, Sharmin

description: Isolation of gene transcripts from desiccated leaf tissue of the resurrection grass Sporobolus stapfianus Gandoger, resulted in the identification of the gene, SDG8i, encoding a Group 1 glycosyltransferase (UGT). Glycolsyltransferases transfer a sugar to a number of acceptor molecules, including hormones and secondary metabolites, changing the solubility, stability and biological activity of these compounds. Functional analysis of the SDG8i was undertaken in Arabidopsis thaliana because no protocol for transformation of resurrection grasses exists. The phenotype of transgenic A. thaliana plants constitutively over-expressing the SDG8i UDP-glucosyltransferase under the control of the CaMV 35S promoter indicates that the glucosyltransferase may modulate the activity of both growth- and stress-related hormones. Plants overexpressing the UGT show elevated auxin levels and results suggest that the enzyme acts downstream of ABA to reduce drought-induced senescence. In vitro analysis of the activity of the UGT recombinant protein product indicates that SDG8i encodes a glucosyltransferase (SL-UGT) that potentially can glycosylate the synthetic analogue GR24, suggesting a link with strigolactone-related processes. As well as mediating the interactions of host plants with symbiotic fungi or parasitic plants, the well-conserved strigolactone hormone signalling system contributes to environmental regulation of plant growth. The phenotypes of SDG8i transgenic plants exhibit hyperbranching and a reduced ability to stimulate strigolactone-dependent germination of Orobanchaceae (Phelipanche ramosa) seed. The results indicate that SDG8i expression negatively affects the bioactivity of a strigolactone-like compound/s produced by Arabidopsis that mediates environmentally-induced repression of cell division and expansion, both during normal development and in response to stress. This leads to enhanced growth, reduced senescence, and a substantial improvement in protoplasmic drought tolerance in SDG8i transgenic plants. Therefore, overexpression of SDG8i confers substantial increases in growth rate and seed yield under non-stress conditions as well as large improvements in survival under cold-, salt- and drought-stress, thus providing a novel means of improving productivity in crop plants. Two putative transcription factors, SDG7y and SDG10y that may regulate SDG8i expression have previously been identified by the yeast-one hybrid system. The transgenic plants over-expressing SDG7y and SDG10y displayed similar phenotypes to that of SDG8i transgenics with substantial increases in shoot growth and shoot branching, suggesting they are driving expression of an Arabidopsis SDG8i orthologue.

description: This study investigated the microbiology in landfill leachate sludge for biological H2 production. This sludge originated from sanitary landfill, hence the microbial community which survived in the sludge may have unique H2-producing features. The landfill leachate sludge was pretreated at different temperatures and landfill leachate sludge pretreated at 65 ºC revealed the maximum H2 yield of 6.43 ± 0.16 mol H2/mol glucose under the optimum conditions of 37ºC and pH 6. This new record of high H2 has exceeded the conventional theoretical yield of 4 mol H2/ mol glucose. Under the same optimum condition (37ºC and pH 6), the H2 produced from dairy wastewater was 113.2 ± 2.9 mmol H2/g COD (12.8 ± 0.3 mmol H2/g carb.). The H2 productions from glucose and wastewater were thermodynamically favourable with the Gibb’s free energy of –34 and –40 kJ/mol, respectively. The microbial community was successfully revealed by 16S-rRNA Metagenomics using Illumin Miseq. Sludge pretreated at 65 ºC was revealed to contain 98% of H2-producing bacteria which mainly belong to the genera Clostridium, Bacillus, Eubacterium and Sporacetigenium. In comparison, untreated sludge which contained mainly H2-consuming bacteria including genera Pseudomonas, Sulfurimonas and Treponema. The sludge pretreatment has successfully eliminated H2-consuming bacteria and enriched H2-producing bacteria which in turn improved H2 yield up to 53%. Three H2-producing bacteria were successfully isolated and identified as Clostridium perfringens strain JJC (AWRZ00000000), C. bifermentans strain WYM (AVSU00000000) and Clostridium sp. strain Ade.TY (AVSV00000000). Based on multiple genome alignment, Clostridium sp. strain Ade.TY is likely to be a new H2-producing species as it does not aligned to the genome of its closest neighbour. The batch mode optimization showed that the maximum H2 production attained from these isolates are in the descending order of C. perfringens strain JJC > C. bifermentans strain WYM > Clostridium sp. strain Ade.TY with yield of 4.68 ± 0.12, 3.29 ± 0.11, 2.87 ± 0.10 mol H2/ mol glucose, respectively. This shows that C. perfringens strain JJC could convert substrates to H2 more efficiently as compared to the others. Nonetheless, it is important to note that the H2 yield from single H2-producing bacterium was less efficient as compared to the performance of H2 production using landfill leachate sludge as inoculum. In summary, landfill leachate sludge contains functional microbial community for efficient H2 production with good potential in industrial application.

description: We show that by integrating out the electric field and incorporating proper boundary conditions, a semiclassical Boltzmann equation can describe electron transport properties, continuously from the diffusive to ballistic regimes. General analytical formulas of the conductance in $D=1,2,3$ dimensions are obtained, which recover the Boltzmann-Drude formula and Landauer-Büttiker formula in the diffusive and ballistic limits, respectively. This intuitive and efficient approach can be applied to investigate the interplay of system size and impurity scattering in various charge and spin transport phenomena.

description: Nyx is a nearby, prograde, and high-eccentricity stellar stream physically contained in the thick disk but with an unknown origin. Nyx could be the remnant of a disrupted dwarf galaxy, in which case the associated dark matter substructure could affect terrestrial dark matter direct detection experiments. Alternatively, Nyx could be a signature of the Milky Way's disk formation and evolution. To determine the origin of Nyx, we obtained high-resolution spectroscopy of 34 Nyx stars using Keck/HIRES and Magellan/MIKE. A differential chemical abundance analysis shows that most Nyx stars reside in a metal-rich ($\mbox{[Fe/H]} > -1$) high-$α$ component that is chemically indistinguishable from the thick disk. This rules out an originally suggested scenario that Nyx is the remnant of a single massive dwarf galaxy merger. However, we also identify five substantially more metal-poor stars ($\mbox{[Fe/H]} \sim -2.0$) that have chemical abundances similar to the metal-weak thick disk. It remains unclear how stars chemically identical to the thick disk can be on such prograde, high-eccentricity orbits. We suggest two most likely scenarios: that Nyx is the result of an early minor dwarf galaxy merger or that it is a record of the early spin-up of the Milky Way disk -- although neither perfectly reproduces the chemodynamic observations. The most likely formation scenarios suggest that future spectroscopic surveys should find Nyx-like structures outside of the Solar Neighborhood.

description: The mobility and multiplication of dislocation clusters in cast Silicon depend on many factors,
especially grain competition and grain boundary types. The great success of High-Performance (HP) mc-Si material
in the last years is mainly based on a high occurrence of stress-absorbing grain boundaries. Where the growth of a
dislocation cluster is confined by a grain boundary, the cluster displays distinct margins. Therefore cluster and grain
show a mutual boundary and a corresponding vertical development. We present an image processing tool that extracts
those regions with corresponding and possibly correlated development of dislocation clusters and grain structure in
multicrystalline silicon (mc-Si), based on photoluminescence (PL) and optical measurements on wafers with a
vertical distance in the brick of 4-8 mm. The vertical development of grain structure and PL signal is reconstructed
layer by layer through the complete brick height and thus allows an insight into the whole crystal development of the
whole brick and a spatially resolved macroscopic 3D-analysis on industrial scale. Grain orientations and grain
boundary types were investigated within regions with corresponding development in and around dislocation clusters.
Exemplary results quantitatively support the general assumption that among the dislocation-suppressing grain
boundaries, random grain boundaries have the largest share with 42%.

description: The derivation of a quasi-geostrophic (QG) system from the rotating shallow water equations on a midlatitude beta-plane coupled with moisture is presented. Condensation is prescribed to occur whenever the moisture at a point exceeds a prescribed saturation value. It is seen that a slow condensation time scale is required to obtain a consistent set of equations at leading order. Further, since the advecting wind fields are geostrophic, changes in moisture (and hence, precipitation) occur only via non-divergent mechanisms. Following observations, a saturation profile with gradients in the zonal and meridional directions is prescribed. A purely meridional gradient has the effect of slowing down the dry Rossby waves, through a reduction in the "equivalent gradient" of the background potential vorticity. A large scale unstable moist mode results on the inclusion of a zonal gradient by itself, or in conjunction with a meridional moisture gradient. For gradients that are are representative of the atmosphere, the most unstable moist mode propagates zonally in the direction of increasing moisture, matures over an intraseasonal timescale and has small phase speed.

description: We propose a new approach for large-scale high-dynamic range computational imaging. Deep Neural Networks (DNNs) trained end-to-end can solve linear inverse imaging problems almost instantaneously. While unfolded architectures provide robustness to measurement setting variations, embedding large-scale measurement operators in DNN architectures is impractical. Alternative Plug-and-Play (PnP) approaches, where the denoising DNNs are blind to the measurement setting, have proven effective to address scalability and high-dynamic range challenges, but rely on highly iterative algorithms. We propose a residual DNN series approach, also interpretable as a learned version of matching pursuit, where the reconstructed image is a sum of residual images progressively increasing the dynamic range, and estimated iteratively by DNNs taking the back-projected data residual of the previous iteration as input. We demonstrate on radio-astronomical imaging simulations that a series of only few terms provides a reconstruction quality competitive with PnP, at a fraction of the cost.

description: The paradigm of extracting work from isolated quantum system through a cyclic Hamiltonian process is a topic of immense research interest. The optimal work extracted under such process is termed as ergotropy [Europhys. Lett., 67 (4), 565(2004)]. Here, in a multi-party scenario we consider only a class of such cyclic processes that can be implemented locally, giving rise to the concept of local ergotropy. Eventually, presence of quantum correlations result in a non-vanishing thermodynamic quantity called ergotropic gap, measured by the difference between the global and local ergotropy. However the converse does not hold in general, i.e. its nonzero value does not necessarily imply presence of quantum correlations. For arbitrary multi-party states we quantify this gap. We also evaluate the difference between maximum global and local extractable work for arbitrary states when the system is no longer isolated but put in contact with a baths of same local temperature.

description: A complete and detailed description of the physical processes occurring in the up conversion phenomena is very difficult to accomplish with complete accuracy. On the one hand, it would be necessary to know how it is distributed luminescent centers in different energy sublevels; and secondly, how does the propagation of light in the converter, and how to deal with this phenomenon. Considering these factors, the objective of this work is to obtain comparative results (I x V) for different materials used as up converters (UC) when incorporated in bifacial silicon solar cells using the unidimensional program PC1-D, in order to get the best candidates for use as UC. Up conversion phenomena consists generally of a non-absorbent matrix containing luminescent centers at a given concentration. The absorption and emission resulting from the luminescence were simplified considering the luminescent center as a series
of three energy levels. With the mathematical approaches developed, was obtained tables with photon density per unit
for all ranges of wavelengths, between 300 and 2100 nm. The simulation was performed assuming a bifacial silicon
solar cell already experimentally characterized and contrasted with theoretical data. Forms of illuminations have been
modified for this solar cell considering the information of UC, where changed the intensities constants (transmitted
sunlight) and conversion efficiency. The simulations of I x V curves demonstrated that UC which absorb at wavelengths
between 1800 and 2000 nm have a better potential in relation to others, the efficiencies found (~20 %) for solar cells
with UCs implemented are shown below the limit values calculated (~36 %). However, approaches the values found
in practice (~16%) and modeled.

description: For the (d+1)-dimensional Lie group G=Z_p^{ imes}ltimes Z_p^{oplus d}, we determine through the use of p-power congruences, a necessary and sufficient set of conditions whereby a collection of abelian p-adic L-functions arises from an element in K_1(Z_p[[G]]). We construct an additive theta map which produces additive p-power congruences, and then using the Taylor Oliver logarithm, we arrive at a multiplicative version of these congruences. If E is a semistable elliptic curve over Q with good ordinary reduction at p, the abelian p-adic L-functions already exist, therefore one can predict many new families of higher order congruences. The first layer congruences are then verified computationally in a variety of cases. The final chapter contains computations for elliptic curves with bad multiplicative reduction at p, that the author performed for Delbourgo and Lei in [10]. All of the computations were done using the package MAGMA.

We also introduce a new observable which accounts for the average rapidity separation among subsequent emissions. Results are presented, for comparison, at leading order and next-to-leading order, with the resummation of collinear double logs proposed in [2].

description: We investigate the many-body behavior of polaritons formed from electron-hole pairs strongly coupled to photons in a two-dimensional semiconductor microcavity. We use a microscopic mean-field BCS theory that describes polariton condensation in quasi-equilibrium across the full range of excitation densities. In the limit of vanishing density, we show that our theory recovers the exact single-particle properties of polaritons, while at low densities it captures non-linear polariton-polariton interactions within the Born approximation. For the case of highly screened contact interactions between charge carriers, we obtain analytic expressions for the equation of state of the many-body system. This allows us to show that there is a photon resonance at a chemical potential higher than the photon cavity energy, where the electron-hole pair correlations in the polariton condensate become universal and independent of the details of the carrier interactions. Comparing the effect of different ranged interactions between charge carriers, we find that the Rytova-Keldysh potential (relevant to transition metal dichalcogenides) offers the best prospect of reaching the BCS regime, where pairs strongly overlap and the minimum pairing gap occurs at finite momentum. Finally, going beyond thermal equilibrium, we argue that there are generically two polariton branches in the driven-dissipative system and we discuss the possibility of a density-driven exceptional point within our model.

description: The international standard IEC62670-3 "Photovoltaic Concentrators (CPV) Performance Testing – Part 3 -
Performance Measurements and Power Rating" sets the guidelines for power measurement of a CPV device, both under indoor
and outdoor conditions. When measuring under outdoor conditions, the acquired data have to be filtered “a posteriori”, in order
to select only those points measured with ambient conditions close to the Concentrator Standard Operating Conditions (CSOC).
The most stringent requirement to be met is related to the three Spectral Matching Ratios (SMR), which have all to be within
the limit of 1.00 ± 0.03. SMR are usually determined by the ratio of the currents of component reference cells set to monitor
the outdoor spectral ratio conditions during the CPV device power measurements. Alternatively the SMR can be calculated
from measured spectral irradiance if the spectral responsivities of the junctions are known. Experience demonstrates that
obtaining real world data meeting these strict conditions is very difficult in practise. However, increasing the acceptable range
would make the entire filtering process less appropriate from a physical point of view.
Given the importance of correctly measuring the SMR, an estimate of their associated measurement uncertainties is needed
to allow a proper assessment of the validity of the 3% limit. In this study a Monte Carlo simulation has been used, to allow a
preliminary estimation of the propagation of uncertainties for SMR measured with a calibrated spectroradiometer.
The method consists of applying both random and wavelength correlated errors to the measured spectra and to the spectral
responsivities of the three CPV cell junctions, accordingly to the measurement uncertainties of the European Solar Test
Installation (ESTI). The experimental data used in this study have been acquired during clear sky conditions in May 2016, at
ESTI's facilities in Ispra, northern Italy (45°49N 8°37E ). Several considerations are then inferred in the case of SMR measured
with component reference cells.

description: Soldering of copper ribbons on busbars is the standard process for the series interconnection of solar cells in industrial PV modules. As an alternative interconnection approach electrical conductive adhesives (ECAs) can be used for cell interconnection. ECAs are lead free and can be processed at temperatures below 200°C.
However, the higher costs and the lower adhesive forces between interconnector and solar cell compared to established solder-based interconnection prevented a larger market share until now. We present results of 90° peeltests according to DIN EN 61189-2:2006 and shear tests according to DIN EN 1465 for seven commercially available ECAs and a comparison to the electrical performance of corresponding 3-cell modules in the temperature cycle test according to IEC 61215. The results show that all samples pass the temperature cycle test with a loss of power below
5%. The measured peel forces decrease after TC600 whereas the shear forces remain at their initial level.

description: This deliverable describes the organisation, results and validation phase of the second Gender STI Co-Design Lab (hereafter the Lab) involving participants from America and Europe.
 The Co-design Lab that took place between October and November 2022 addressed the Gender STI objectives to integrate the gender perspective in bilateral and multilateral agreements between the EU Member States (MS), Associated Countries (AC) and third countries through design thinking methods and participatory techniques.
 The document describes the methods, participatory steps and tools that have been applied in the Lab to co-design shared solutions and prototypes for common challenges regarding gender inequalities in STI and to support the emergence of an international community of practitioners with similar challenging objectives. More specifically, the deliverable collects in detail “what” was done and how it was done in the Lab, reflects on the “so what” question, as to the sense and purpose of the challenge-based prototypes and their initial outputs, and finally draws some conclusions with a “now what” reflection on what was learnt and suggests possible priorities for future actions.

description: We use a network of chiral junctions to construct a family of topological chiral spin liquids in two spatial dimensions. The chiral spin liquid phase harbors SU(2)$_k$ anyons, which stem from the underlying SU(2)$_k$ WZW models that describe the constituent spin chains of the network. The network exhibits quantized spin and thermal Hall conductances. We illustrate our construction by inspecting the topological properties of the SU(2)$_2$ model. We find that this model has emergent Ising anyons, with spinons acting as vortex excitations that bind Majorana zero modes. We also show that the ground state of this network is threefold degenerate on the torus, asserting its non-Abelian character. Our results shed new light on the stability of non-Abelian topological phases in artificial quantum materials.

description: Site-occupancy disorder, defined as the non-periodic occupation of lattice sites in a crystal structure, is a ubiquitous phenomenon in solid-state physics and chemistry. Examples are mineral solid solutions, synthetic non-stoichiometric compounds and metal alloys. The experimental investigation of these materials using diffraction techniques only provides averaged information of their structure. However, many properties of interest in these solids are determined by the local geometry and degree of disorder, which escape an "average crystal" description, either from experiments or from theory. In this paper, we describe a methodology for the computer simulation of site-disordered solids, based on the consideration of configurational ensembles and statistical mechanics, where the number of occupancy configurations is reduced by taking advantage of the crystal symmetry of the lattice. Thermodynamics and non-thermodynamic properties are then defined from the statistics in the symmetry-adapted configurational ensemble. We will briefly summarize and discuss some recent applications of this methodology to problems in materials science.

Characterisation & Simulation Methods

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 266-270
description: Light absorption within a solar cell's dielectric coatings represents a loss mechanism that proves challenging to
measure, particularly at short wavelengths at which the substrate is strongly absorbing. This paper presents a method based on
measurements of the spectral response of photoluminescence that determines a relative measure of the absorption in a dielectric
coating. The use of the spectral response of photoluminescence is suggested as it is a contactless and non-destructive technique
that can be applied to a solar cell at any stage of production. The absorptance determined from this method is compared to
ellipsometry measurements on polished samples, and is then used to determine the absorptance of a silicon nitride layer on the
textured surface of a screen printed solar cell.

description: Time-dependent density functional theory is widely used to describe excitations of many-fermion systems. In its many applications, 3D coordinate-space representation is used, and infinite-domain calculations are limited to a finite volume represented by a box. For finite quantum systems (atoms, molecules, nuclei), the commonly used periodic or reflecting boundary conditions introduce spurious quantization of the continuum states and artificial reflections from boundary; hence, an incorrect treatment of evaporated particles. These artifacts can be practically cured by introducing absorbing boundary conditions (ABC) through an absorbing potential in a certain boundary region sufficiently far from the described system. But also the calculations of infinite matter (crystal electrons, quantum fluids, neutron star crust) suffer artifacts from a finite computational box. In this regime, twist- averaged boundary conditions (TABC) have been used successfully to diminish the finite-volume effects. In this work, we extend TABC to time-dependent framework and apply it to resolve the box artifacts for finite quantum systems using as test case small- and large-amplitude nuclear vibrations. We demonstrate that by using such a method, one can reduce finite volume effects drastically without adding any additional parameters. While they are almost equivalent in the linear regime, TABC and ABC differ in the nonlinear regime in their treatment of evaporated particles.

Manufacturing & Production

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 280-285
description: With the advancement of photovoltaics (PV) in the energy markets and the rapid technological
developments, the existence of planned PV technology roadmaps becomes beneficial. The International Technology
Roadmap for Photovoltaic (ITRPV) has proven itself to be a leading PV technology roadmap in the crystalline silicon (c-
Si) field. The yearly reports and the widening scope of its structured projections cover essential factors in the value chain
of PV production. The main aim of having a summative accuracy study of the ITRPV is to assist research and
development scientists, engineers and investors in taking attentive decisions. The importance of the ITRPV increases with
the reliability and accuracy of its projections. In this work, the accuracy analysis of the ITRPV is performed by choosing
topics and gathering the data from the yearly ITRPV reports. As projection accuracy measures, projection absolute
deviations (PADs) and projection absolute percentage deviations (PAPDs) are considered paving the way for mean
projection absolute deviation (MPAD) and mean projection absolute percentage deviation (MPAPD) deductions. In our
case the 8th edition report projecting values for six topics are taken as reference values while 2016 projected values from
2nd till 8th editions are taken for the PAD study. Using our approach, different graphical representations show the
projection absolute deviations and projection absolute percentage deviations from the chosen reference values. For
instance, considered multicrystalline silicon wafer thickness projections have shown an MPAD of 26,7 μm and an
MPAPD of 14,8%. Considering the six projection topics, MPAPD as a function of projection time interval is deduced. A
time dependent inaccuracy is then used to plot expected ranges for future projection values of each studied topic. From a
cost perspective, for the silver amount per cell, an MPAD of 13 mg/cell could correspond to an inaccuracy of around
0,078 €/cell for a given silver price. ITRPV projection accuracy leads to enhancing cost-effective decision making.

description: The aim of this research is to demonstrate achievements and difficulties of using large amplitude Fourier transformed (FT) alternating current (AC) voltammetry for measurement of the electrode kinetics of fast electron transfer processes. Research is focussed on study of outer-sphere electron transfer processes at electrode/solution interface. Electrode kinetics of these processes have been investigated by varying the electrode size from macro to microdisk electrodes, increasing AC frequency to enhance the sensitivity of the method for determination of electrode kinetics.

description: Quantum dot arrays provide a promising platform for quantum information processing. For universal quantum simulation and computation, one central issue is to demonstrate the exhaustive controllability of quantum states. Here, we report the addressable manipulation of three single electron spins in a triple quantum dot using a technique combining electron-spin-resonance and a micro-magnet. The micro-magnet makes the local Zeeman field difference between neighboring spins much larger than the nuclear field fluctuation, which ensures the addressable driving of electron-spin-resonance by shifting the resonance condition for each spin. We observe distinct coherent Rabi oscillations for three spins in a semiconductor triple quantum dot with up to 25 MHz spin rotation frequencies. This individual manipulation over three spins enables us to arbitrarily change the magnetic spin quantum number of the three spin system, and thus to operate a triple-dot device as a three-qubit system in combination with the existing technique of exchange operations among three spins.
Analytic and numerical studies of envelope solitons in geophysical flows

description: While not as widely discussed as long wave soliton models of atmospheric and oceanic phenomena envelope soliton solutions to the nonlinear Schrodinger equation have been proposed to describe events such as mid latitude planetary scale dipole blocks, Rossby wave breaking in the extratropical tropopause and equatorial Rossby-gravity ocean waves. Despite these applications, most studies have been limited to the case of constant zonal shear, and little work has been done on the effects of baroclinicity or variable shear on these weakly nonlinear structures. The purpose of this thesis is twofold. Firstly, numerical methods will be developed, based on the spectral element method, for representing geophysical flows in a hierarchy of systems of increasing physical complexity, from barotropic QG flows through to layered shallow water flows capable of representing baroclinic instability and ageostrophic effects. Particular emphasis will be given to splitting methods used to solve the different barotropic and baroclinic modes, and to the use of the rigid lid constraint for removing fast barotropic gravity waves. Parallel to this, weakly nonlinear perturbation analysis will be applied to investigate the evolution and stability of envelope solitons for quasi-geostrophic flows, with particular emphasis on the effects of variable shear, stratification and topography. For shear flows undergoing topographic and baroclinic instability for which the analysis cannot be applied, the numerical models developed here will be used to investigate the evolution of these instabilities.
Search for supersymmetry in final states with a single electron or muon using angular correlations and heavy-object identification in proton-proton collisions at $\sqrt{s}$ = 13 TeV

description: A search for supersymmetry is presented in events with a single charged lepton, electron or muon, and multiple hadronic jets. The data correspond to an integrated luminosity of 138 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV, recorded by the CMS experiment at the CERN LHC. The search targets gluino pair production, where the gluinos decay into final states with the lightest supersymmetric particle (LSP) and either a top quark-antiquark ($\mathrm{t\bar{t}}$) pair, or a light-flavor quark-antiquark ($\mathrm{q\bar{q}}$) pair and a virtual or on-shell W boson. The main backgrounds, $\mathrm{t\bar{t}}$ pair and W+jets production, are suppressed by requirements on the azimuthal angle between the momenta of the lepton and of its reconstructed parent W boson candidate, and by top quark and W boson identification based on a machine-learning technique. The number of observed events is consistent with the expectations from standard model processes. Limits are evaluated on supersymmetric particle masses in the context of two simplified models of gluino pair production. Exclusions for gluino masses reach up to 2120 (2050) GeV at 95% confidence level for a model with gluino decay to a $\mathrm{t\bar{t}}$ pair (a $\mathrm{q\bar{q}}$ pair and a W boson) and the LSP. For the same models, limits on the mass of the LSP reach up to 1250 (1070) GeV.
