description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 3806-3811
description: Typical photovoltaic installations suffer from numerous limitations. Many of these limitations stem from
power losses – whether due to module mismatch, tilt and orientation mismatch, or partial shading. Other limitations stem
from system design constraints, lack of granular monitoring and analysis abilities, and insufficient safety features. The
distributed PV power harvesting and monitoring solution presented in this work introduces module-integrated electronics
(PowerBox) that works in tandem with a proprietary inverter. The module-integrated electronics enable optimization of the
power output from each module via module-level MPPT. The distributed system adds PV energy in real-life scenarios,
provides module-level monitoring and safety mechanisms for automatic module shutdown, and overcomes design limitations
of traditional inverters. This paper presents field results from comparative studies done in multiple locations around the
globe. In each location, a comparison of the energy yield of two installations exposed to identical conditions is performed,
wherein a traditional single inverter system is adjacent to a distributed DC system of identical layout connected to a
SolarEdge inverter and with a PowerBox per module. The power outputs from both installations under various conditions are
compared in order to assess potential benefits in real-life scenarios, and an analysis of the energy production gains is
performed. In most cases SolarEdge systems have surpassed the energy output of the reference (traditional) systems,
harvesting 3% – 14% more energy in some of the sites.

description: A finite family ${\mathcal B}$ of balls with respect to an arbitrary norm in ${\mathbb R}^d$ ($d\geq 2$) is called a non-separable family if there is no hyperplane disjoint from $\bigcup {\mathcal B}$ that strictly separates some elements of ${\mathcal B}$ from all the other elements of ${\mathcal B}$ in ${\mathbb R}^d$. In this paper we prove that if ${\mathcal B}$ is a non-separable family of balls of radii $r_1, r_2,\ldots , r_n$ ($n\geq 2$) with respect to an arbitrary norm in ${\mathbb R}^d$ ($d\geq 2$), then $\bigcup {\mathcal B}$ can be covered by a ball of radius $\sum_{i=1}^n r_i$. This was conjectured by Erdos for the Euclidean norm and was proved for that case by A. W. Goodman and R. E. Goodman [Amer. Math. Monthly 52 (1945), 494-498]. On the other hand, in the same paper A. W. Goodman and R. E. Goodman conjectured that their theorem extends to arbitrary non-separable finite families of positive homothetic convex bodies in ${\mathbb R}^d$, $d\ge2$. Besides giving a counterexample to their conjecture, we prove that conjecture under various additional conditions.

description: This article examines the causes of uncertainty in yield calculations for PV systems. Individual loss factors are assigned to
the different portions of this uncertainty. The dependency on irradiance, based on the weather data used and the uncertainty
range of the conversion model used, is the dominating factor. When suitable measures are taken, the uncertainty for highquality
yield analyses can be reduced to less than 4%.

description: Design-oriented research typically involves some kind of research problem discovery activity in order to identify and understand the problem space. Researchers can apply different methods to explore the problem space, for instance, interviews or focus groups. However, these methods are time consuming and do not scale well. Especially when it comes to discovering socially relevant realworld problems they require access to the general public to reach domain experts that is often difficult to achieve for researchers. Citizen science offers a promising approach for research problem discovery by actively involving citizens into the scientific inquiry to access knowledge on a large scale. In this paper, we report on a participatory action following a digital citizen science approach by specifically exploring the topic "home office" and corresponding challenges along four different subtopics. We report on (1) our approach and process to involve citizens in the problem discovery phase, (2) the implementation of the process in theweb-based digital citizen science application MyResearchChallenge to enable citizens to register, collect, discuss, and vote challenges, and (3) provide a summary on the collected challenges.

Ein empirischer Ansatz wird vom Projekt EMPAMOS verfolgt, das Spielanleitungen von Gesellschaftsspielen nach Spiel-Design-Elementen durchsucht.Werden in verschiedenen Spielen Kandidaten für Muster gefunden, werden die Textstellen gesammelt und von Fachkräften diskutiert. Am Ende des Prozesses steht die Definition eines Spiel-Design-Elementes. Diese Arbeit stellt einen Ansatz vor, der Fachkräfte für Spiel-Design-Elemente bei der Suche nach neuen Elementen unterstützt, in dem aus den gefunden Textstellen eine möglichst allgemeingültige Definition für das jeweilige Spiel-Design-Element generiert werden soll.
Effects of Mg/Si on Exoplanetary Refractory Oxygen Budget

description: Solar photospheric abundances of refractory elements mirror the Earth's to within ~10 mol% when normalized to the dominant terrestrial planet-forming elements Mg, Si and Fe. This allows for the adoption of Solar composition as an order-of-magnitude proxy for Earth's. It is not known, however, the degree to which this mirroring of stellar and terrestrial planet abundances holds true for other star-planet systems without determination of the composition of initial planetesimals via condensation sequence calculations and post condensation processes. We present the open-source Arbitrary Composition Condensation Sequence calculator (ArCCoS) to assess how the elemental composition of a parent star affects that of the planet-building material, including the extent of oxidation within the planetesimals. We demonstrate the utility of ArCCoS by showing how variations in the abundance of the stellar refractory elements Mg and Si affect the condensation of oxygen, a controlling factor in the relative proportions of planetary core and silicate mantle material. This, thereby, removes significant degeneracy in the interpretation of the structures of exoplanets as well as providing observational tests for the validity of this model.

description: The Sol-ion system, an integrated system combining lithium-Ion storage technology with highly
efficient PV inverter technology, supports two different philosophies of self consumption: The off-grid approach,
where loads are directly connected to the inverter, and the on-grid approach, where self consumption is realized, if
the load balance at the grid connection equals to zero.
First systems have already been installed at Fraunhofer IWES, voltwerk electronics and Tenesol and first
performance measurement have been done, to verify the feasibility of this integrated concept.

Los resultados de dicha investigación, dieron cuenta de que variables tradicionalmente asociadas a variaciones del Sistema Inmune (SI), como es el caso de la depresión, no arrajaban correlaciones significativas, a excepcion del Apoyo Social en su dimension de Amistades. Dada, por una parte, la escasez de investigación existente que vincule la variables Apoyo Social con variaciones en el Sistema Inmune de PVVIH y la variedad de resultados a nivel mundial obtenidos a partir del estudio con dicha variable, es que se estimó de relevancia contar con un estudio que aborde en una dimensión cuantitativa y cualitativa la variable Apoyo Social Percibido, a fin de aportar algunos datos más respecto de la relevancia de dicha variable en el proceso de salud - enfermdad entre quienes portan el VIH.

description: Users frequently receive cookie consent notices when they enter a website. They are supposed to enable an informed decision about data collection. Instead, they often contain deceptive designs - also known as dark patterns - that can nudge users to consent and thus compromise their privacy. In this paper, we explore the causes of the widespread use of dark patterns in cookie consents. To do so, we take the perspective of website operators, who are responsible for the use of cookie consent notices and are increasingly making use of Consent Management Platforms (CMPs) to manage end-user consent. CMPs usually contain certain design templates. To find out whether it is possible for website operators to generate notices without dark patterns using CMPs, we analyzed a selection of the templates offered by major CMPs. We show that 60% of the notices created with default settings contain at least one dark pattern. A notice that does not nudge toward a certain choice could only be generated with 62.5% of the CMPs. Our results imply that the responsibility for privacy-friendly notices lies more with the CMPs than with the website operators.

description: In this work we present a comparative analysis of excitonic features in the photoluminescence (PL) spectra measured at 4.2, 78 and 300 K in CuInS2, grown by the traveling heater (THM) and the chemical vapor transport (CVT) methods. The A free exciton in the crystals grown by the THM method, reveals a doublet, corresponding to the lower (ALPB) and upper (AUPB) polariton branches, and a number of bound excitonic lines whereas the PL spectra of the crystals grown by CVT method exhibit a single line of the A exciton and only three bound exciton lines. Excited states of the free A excitons were observed in the PL spectra of the crystals grown by both methods. Binding energy of the A exciton of 18.5 meV and 19.7 meV have been estimated using the hydrogenic model for the THM and CVT grown crystals, respectively. The Bohr radii of the exciton, dielectric constants and the bandgaps in the two types of CuInS2 are calculated.

Fungal spoilage limits the shelf life of fermented dairy products. To address the problem, this study explores the potential of lactic acid bacteria as antifungal adjunct cultures in dairy matrices. Strains of lactic acid bacteria (113) representing 19 species were screened for their activity against Penicillium caseifulvum, Aspergillus clavatus and Mucor racemosus in modified MRS medium, milk, and yogurt. Strains of Lactiplantibacillus plantarum, Furfurilactobacillus milii, and Lentilactobacillus parabuchneri inhibited the growth of mycelial fungi. The inhibitory effects of lactic acid bacteria against yeasts were also determined in yogurt with Candida sake, Saccharomyces bayanus, and Torulaspora delbrueckii as challenge strains. The inhibition of yeasts by lactic acid bacteria was strain-specific and unrelated to the activity towards mycelial fungi. Organic acids and hydroxy fatty acids were quantified by liquid chromatograph coupled with refractive index detector and tandem mass spectrometry, respectively. Principal component analysis indicated 10-OH 18: 1 fatty acids and acetate are the main antifungal metabolites and explained over 50 % of the antifungal activity. The correlation analysis of metabolites and mold-free shelf life of milk and yogurt confirmed the role of these compounds. The genomic study analysed genes related to the production of major antifungal metabolites and predicted the formation of 1,2-propanediol and acetate but not of hydroxy unsaturated fatty acids. The findings provide new perspectives on the selection of antifungal strains, the characterization of antifungal metabolites and the exploration of antifungal mechanisms among different species.

In einer Studie mit 52 Teilnehmenden wurde untersucht, ob persuasive UI-Elemente wie Dark und White Pattern die User Experience und das Vertrauen der User beeinflussen. Die verwendeten Cookie- Banner hatten entweder keine persuasiven UI Elemente (N), zwei unterschiedlich starke Dark Pattern (Dp1 und Dp2) oder ein White Pattern (Wp). Das starke Dark Pattern (Dp2) verringerte die User Experience- und Usability-Bewertung der Nutzenden, im Vergleich zum neutralen Design (N). Cookie Banner mit leichten Dark Pattern (Dp1) führten zu höheren positiven Emotionen als das neutrale Design (N). Wenn die Affinität zur Technologie der Teilnehmenden berücksichtigt wurde, dann erhöhte sich das wahrgenommene Vertrauen bei der Interaktion mit starkem Dark Pattern (Dp2) im Vergleich zum neutralen Design (N). Die Ergebnisse implizieren, dass User das manipulative Design nicht unbedingt als solches wahrnehmen. Dies wirft die Frage auf, ob es ethisch vertretbar ist, User durch Interface Design zum Zweck der Datengewinnung zu manipulieren.

description: Previously, using a thin film of Fluorine doped Indium Oxide (IFO) as transparent electrode and
gridlines made of copper wire, i.e. the so-called Laminated Grid Cell (LGCell) design, we prepared concentrator
solar cell based on the IFO/(n+pp+)Cz-Si structure, which revealed the series resistance of 0.24 Ω cm2 and the optimal
concentration level of 3-4X. It was concluded that the application of a thinner silicon wafer with lower resistivity (as
compared with the values of 320 μm and 5 Ω·cm used previously) will result in the increase of the optimal
concentration level. In the present work for the manufacturing of the LGCells we used 200 μm thick Cz-Si wafers
with the resistivity of 0.5 Ω·cm. The series resistance of the cell reduced down to 0.13 Ω·cm2 and, correspondingly,
the optimal operating level increased up to ~7X. Obtained LGCells showed the efficiency of 15.25% at 1X and
16.25% at 7X. Thus, we have proved that LGCell design of contact system is acceptable for manufacturing lowconcentrator
silicon solar cells.

description: In this work we study, theoretically, electronic mobility of the silicon carbide semiconductor in the 3C phase, named 3C-SiC. 3C-SiC has shown great potential for applications in extreme conditions. Thus, the study of the electronic mobility of this semiconductor is of great interest. In this work were theoretically deduced: drift velocity, displacement and mobility of the charge carriers in the n-type doped 3C-SiC semiconductor, subjected to a constant electric field. The dependence of these transport properties as a function of the intensity of the electric field and temperature was analyzed. For this, a differential equation of motion was used with a source term (low intensity electric fields) and a term of resistance to movement (electrical resistance).

description: In the papers dealing with derivation and applications of operational matrices of Bernstein polynomials, a basis transformation, commonly a transformation to power basis, is used. The main disadvantage of this method is that the transformation may be ill-conditioned. Moreover, when applied to the numerical simulation of a functional differential equation, it leads to dense operational matrices and so a dense coefficient matrix is obtained. In this paper, we present a new property for Bernstein polynomials. Using this property, we build exact banded operational matrices for derivatives of Bernstein polynomials. Next, as an application, we propose a new numerical method based on a Petrov-Galerkin variational formulation and the new operational matrices utilizing the dual Bernstein basis for the time-fractional advection-dispersion equation. Finally, we show that the proposed method leads to a narrow-banded linear system and so less computational effort is required to obtain the desired accuracy for the approximate solution. Some numerical examples are provided to demonstrate the efficiency of the method.

The results of simulations are validated by comparison with the experimental data of the ion mobility and the transverse diffusion. The IVDF simulation study shows that due to significant effect of scattering in elastic collisions IVDF cannot be separated into product of two independent IVDFs in the transverse and parallel to the electric field directions.

description: In the fabrication of silicon solar cells process, impurity doping process is indispensable to form
junctions. Now, instead of the conventional thermal diffusion method, laser doping (LD) technique is noticed as
alternative because of its many advantages. Until now, many researchers have been carried out on the laser doping
using the double frequency pulsed laser, however, it needs expensive optics and equipment. In this study, we tried to
apply the LD method to the silicon solar cell fabrication process using the double frequency Continuous Wave (CW)
laser and investigated LD on the laser irradiation condition. Doping profiles were widely controlled by changing the
laser output power, focus condition and scanning speed. And, the solar cells prepared by the LD technique at the
optimized condition showed the diode characteristics and photovoltaic performance. Moreover, it was confirmed that
the photovoltaic property related to the laser irradiation condition.

description: Evaluations should be conducted regularly throughout the development of interactive applications to ensure and improve usability. Automated approaches can enable time- and cost-effective evaluations, as the participation of test and expert personnel is not required. Especially in early phases of development, usability evaluations could thus be made possible without much effort. This paper describes a concept for automated usability evaluation of UI prototypes that supports the design and can complement classical usability evaluation methods. To test this concept, a plugin was implemented that evaluates design drafts in the Figma prototyping tool. The evaluation is based on usability metrics, a GOMS model for modelling interaction sequences that also supports predicting processing time and hint patterns for identifying usability problems in interaction sequences. The tool was tested and evaluated in a number of trials, which provided insights into the suitability of the concept and identified approaches for further development.

description: This work presents the development of a facility to measure spectral response on III-V solar cells for
space applications. This development was performed in the frame of a cooperation agreement between the Argentine
National Atomic Energy Commission (CNEA) and the Argentine National Commission for Space Activities
(CONAE), which is addressed in these first stages to SAOCOM and SAC-D satellites. The setup is particularly
oriented to measure triple junction (TJ) InGaP/GaAs/Ge cells, the same type that will be used in the next CONAE
satellites solar arrays, but it can be utilized to measure other devices. The equipment is based on narrowband
interference filters and two dichroic lamps as bias light source to select the subcell to be measured, whereas a simple
incandescent lamp is used to generate the monochromatic light beam. Signal is measured on an appropriate
resistance inserted in a serial circuit using a lock-in amplifier. Measurement is fully automated, which allows
operator independent results. Preliminary results show the good performance of this setup.

description: Nonlocal correlations arising from measurements on tripartite entangled states can be classified into two groups, one genuinely $3-$way nonlocal and other local with respect to some bipartition. Still, whether a genuinely tripartite entangled quantum state can exhibit genuine $3-$way nonlocality, remains a challenging problem so far as measurement context is concerned. Here we introduce a novel approach in this regard. We consider three tripartite quantum states none of which is genuinely $3-$way nonlocal in a specific Bell scenario (three parties, two measurements per party, two outcomes per measurement), but they can exhibit genuine $3-$way nonlocality when the initial states are subjected to stochastic local operations and classical communication (SLOCC). So, genuine $3-$way nonlocality is a resource, which can be revealed by using a sequence of measurements.

description: The studies about the key technologies in our pilot production line of CdTe thin film solar modules are
introduced in the paper. The structure of the modules is SnO2:F/CdS/CdTe/back-contact layer/Ni. The main
fabrication technologies that include the chemical bath deposition of CdS layer, closed space sublimation deposition
of CdTe layer, annealing of CdTe layer, surface etching of CdTe layer, fabrication and annealing of back contact
layers, laser scribe of transparent conducting layers and semiconductor layers in the pilot line are discussed. The
back contact layers of both kinds: CuxTe and graphite glue, are investigated. The effects of weaknesses that may
make some local short circuit on the module performance are analyzed. The relationship between the series
resistance of a module and that of cells is studied. A module efficiency of 9.5% has been obtained.
Keywords: CdTe thin film solar cells, pilot production line, back contact.

description: Digitale Bildungsangebote bieten eine dezentrale und flexible Chance für frühpädagogische Aus-, Fort- und Weiterbildung. Sie können individuelles mit institutionalisiertem Lernen transmedial verbinden und die Vereinbarkeit von Arbeit mit Lernsituationen im Kita- Alltag fördern. Fraglich ist, weshalb digitale Lehr- und Lernformate bisher kein fester Bestandteil der frühpädagogischen Weiterbildungslandschaft sind [1]. Wie digital unterstützte Lernformate, deren Zugänge und Gebrauchsszenarien gestaltet werden können, damit Kita-Fachkräfte kontextspezifisches Fachwissen erhalten und dieses auch im Kita-Alltag anwenden können, untersucht das interdisziplinäre Forschungsprojekt PIIQUE. Mit unserem Beitrag stellen wir partizipative Methoden ins Zentrum, anhand derer wir die Potenziale und Limitierungen für frühpädagogische Forschungsund Entwicklungsprojekte diskutieren. Zudem legen wir dar, wie wichtig die Kommunikationsformate und die Ansprache der Teilnehmenden für den Projektverlauf sind.

description: A novel algorithm is provided to couple a Galilean invariant model with curved spatial background by taking nonrelativistic limit of a unique minimally coupled relativistic theory, which ensures Galilean symmetry in the flat limit and canonical transformation of the original fields. That the twin requirements are fulfilled is ensured by a new field, the existence of which was demonstrated recently from Galilean gauge theory. The ambiguities and anomalies concerning the recovery of Galilean symmetry in the flat limit of spatial non relativistic diffeomorphic theories, reported in the literature, are focused and resolved from a new angle.

Work Ethic Data

Subjects: subject: Business
subject: Human Resources Management

description: This study presents cross-cultural research on work ethic among three nations: the British, the UAE, and Serbian. Moreover, it examines the relationship between work ethic and organizational performance and investigates the influence of respondents' career stage on their work ethic. In this study, we have used the short form of Multidimensional Work Ethic Profile (MWEP) to collect data since MWEP doesn’t analyse work ethic in the context of religion. We contribute to the theory by comparing work ethics in developed, developing and a country in socio-economic transition. The results also show an influence of respondents' career stage on their work ethic and a significant relationship between different dimensions of work ethic and organizational performance for all three nations.

description: Be-greifbare Interaktion vollzieht sich im Wesentlichen über die Manipulation physischer Objekte und durch den Einsatz des eigenen Körpers. Sie bezieht damit die Umgebung und den physischen Nutzungskontext in viel stärkerer Weise ein als rein grafische oder sprachbasierte Schnittstellen zur Steuerung von Mensch-Computer- Systemen. Die vielfältigen Möglichkeiten, Sensoren und Computersysteme in die Umwelt und ihre Gegenstände zu integrieren, bietet einen großen Gestaltungsspielraum. Das Forschungsfeld der »Be-greifbaren Interaktion« (Tangible Interaction) untersucht diesen Spielraum wissenschaftlich und praktisch, um sinnvolle und menschengerechte Anwendungen zu ermöglichen. Die Fachgruppe »Be-greifbare Interaktion« des GI-Fachbereichs Mensch-Computer- Interaktion bietet in ihrem gleichnamigen Workshop ein Forum zur Präsentation des wissenschaftlichen Diskurses und der interdisziplinären Auseinandersetzung, wobei Beitragsformen über theoretische, kritische und zukunftsweisende Reflexionen, bis hin zu gestalterischen Arbeiten und Berichten praktischer Umsetzungen gehen. DerWorkshop öffnet die Diskussion für ein breiteres Fachpublikum, um aktuelle Entwicklungen offengelegt und neue Impulse für das Forschungsgebiet geschaffen werden.
Testing Feedback-Modified Dark Matter Haloes with Galaxy Rotation Curves: Estimation of Halo Parameters and Consistency with $Λ$CDM

description: Cosmological $N$-body simulations predict dark matter (DM) haloes with steep central cusps (e.g. NFW, Navarro et al. 1996). This contradicts observations of gas kinematics in low-mass galaxies that imply the existence of shallow DM cores. Baryonic processes such as adiabatic contraction and gas outflows can, in principle, alter the initial DM density profile, yet their relative contributions to the halo transformation remain uncertain. Recent high resolution, cosmological hydrodynamic simulations (Di Cintio et al. 2014, DC14) predict that inner density profiles depend systematically on the ratio of stellar to DM mass (M$_*$/M$_{\text{halo}}$). Using a Markov Chain Monte Carlo approach, we test the NFW and the M$_*$/M$_{\text{halo}}$-dependent DC14 halo models against a sample of 147 galaxy rotation curves from the new {\it Spitzer} Photometry and Accurate Rotation Curves (SPARC) data set. These galaxies all have extended H{\small I} rotation curves from radio interferometry as well as accurate stellar mass density profiles from near-infrared photometry. The DC14 halo profile provides markedly better fits to the data compared to the NFW profile. Unlike NFW, the DC14 halo parameters found in our rotation curve fits naturally fall within two standard deviations of the mass-concentration relation predicted by $Λ$CDM and the stellar mass-halo mass relation inferred from abundance matching with few outliers. Halo profiles modified by baryonic processes are therefore more consistent with expectations from $Λ$ cold dark matter ($Λ$CDM) cosmology and provide better fits to galaxy rotation curves across a wide range of galaxy properties than do halo models that neglect baryonic physics. Our results offer a solution to the decade long cusp-core discrepancy.

description: The sequence of laser chemical processing (LCP) and electrochemical metal deposition direct on
silicon is presented as the next generation of front grid metallization. The subsequent metallization process after
selective emitter forming works self aligned and shows structures with line width as thin as ~40 μm. Simulations give
confidence that efficiency improvements in the range of 1% are achievable as compared to industrial screen printed
solar cells.
To reach best contact resistance first nickel was plated on locally high doped areas which were produced by LCP
method. This layer is followed by thick by silver plating. If thickening is done by copper the prior nickel also needs
to built up to serves as a diffusion barrier. Only copper as a strong cost reducing process (-70% compared to pure
silver) needs a third metal layer like tin or thin silver to achieve a solderable surface finishing. Both sequences were
applied to produce high efficient solar cells with a new front grid metallization cluster without using printing
methods. All presented plating processes were carried out on a industrial production platform which ensures a single
side wet chemical treatment.

description: In the realm of Open Science, research assessment stands as a crucial cornerstone. The global consensus points towards a necessary shift to a more quality and impact-based approach, one that embraces a broader spectrum of research outputs while safeguarding research integrity and reproducibility. Presently, research assessment systems heavily lean on quantitative journal- and publication-based metrics, limiting the scope of evaluation. This narrow focus brings forth linguistic, geographic, thematic, and commercial biases that impede scientific progress. In response to these challenges, initiatives such as CoARA in Europe and FOLEC-CLACSO in Latin America and the Caribbean have emerged, uniting decision-makers, research organizations, and the scholarly community in implementing coordinated Open Science practices within research assessment. The time is ripe for collective action. A concerted effort is needed to drive reforms across diverse research assessment systems and practices, with the ultimate aim of bolstering research quality, fostering openness, enhancing performance, and magnifying societal impact. By embracing an inclusive approach, we can propel the scientific community towards a future of collaborative and transformative research. Key topics of this session: The Nexus between Research Assessment and Open Science Expanding the Horizons: Integrating Diverse Research Outputs Overcoming Biases: Ensuring Fairness in Research Assessment Collaborative Initiatives for Open Science in Assessment: CoARA and FOLEC-CLACSO Emphasizing Change: The Urgent Need for Reform
