description: It has been argued that self-replicating robotic probes could spread to all stars of our galaxy within a timespan that is tiny on cosmological scales, even if they travel well below the speed of light. The apparent absence of such von Neumann probes in our own solar system then needs an explanation that holds for all possible extraterrestrial civilisations. Here I propose such a solution, which is based on a runaway error propagation that can occur in any self-replicating system with finite accuracy of its components. Under universally applicable assumptions (finite resources and finite lifespans) it follows that an optimal probe design always leads to an error catastrophe and breakdown of the probes. Thus, there might be many advanced civilizations in our galaxy, each surrounded by their own small sphere of self-replicating probes. But unless our own solar system has the extraordinary luck to be close enough to one of these civilizations, none of these probes will ever reach us.

description: The international standards currently used strongly underestimate the real conditions of the Atacama Desert, Chile. ATAMOSTEC aims to create PV technologies adapted to the desert and a Chilean Desert Label to boost the local solar industry, and to contribute on the decrease of the LCOE of PV technologies (Modules, BoS and O&M). We present preliminary work performed in ATAMOSTEC Consortium as the base to create the Chilean Desert Label for PV technologies and our vision on the future of PV research and development applied to the industry. Furthermore, the ATAMO n-type PV technology has been exposed outdoor for seven months and preliminary results are shown.

PV Module Design, Manufacture, Performance and Reliability

description: 37th European Photovoltaic Solar Energy Conference and Exhibition; 1038-1046
description: During PV module manufacturing, the solar cells are thermomechanically loaded and therefore residual stresses are induced. These significant residual stresses combined with additional stresses due to mechanical loads can lead to cell cracks which may not affect the electric efficiency initially but over a period of time the effect may become significant as PV modules are subjected to environmental loads in the field. Therefore, the study of the accumulation of residual stresses and strains from each life stage is of great importance in order to improve the reliability and thus the lifetime of crystalline silicon (c-Si) PV modules. An advanced 3D coupled thermomechancal structural numerical model considering the manufacturing processes and the subsequent mechanical and thermal loading phases in a consecutive stepby-step manner is developed using the finite element modelling approach. The present study is carried out for an in-depth investigation on the effect of the thermomechanical behaviour and stress distribution on the crack sensitive regions in PV modules during their entire life. The results are useful for optimisation of material properties and the development of advanced design strategies.

description: Performance loss of crystalline silicon PV modules due to potential induced degradation (PID) is often an issue in older PV power plants. However, PID has to be assessed also for novel and projected installations. For the owner of PV power plants, it is important to deduce future yield expectations from current measurements and observations. In the case of PID, many influencing factors including environmental conditions, solar cell type and module encapsulation properties lead to complex behavior under high voltage stress in real installations. State-of-the-art methods using artificial neural networks (ANN) enable a connection of these influencing factors towards a prediction of degradation and recovery. In this work data is acquired from 11 Al-BSF silicon modules susceptible to PID of the shunting type (PID-s) under realistic high voltage stress, together with corresponding environmental data over a period of 20 months. Specific PID and recovery rates, which are acquired on the basis of accelerated PID testing, and the environmental data served as input parameters for the ANN to predict the performance ratio (PR) of individual modules. The ANN prediction capabilities were tested with a module unknown to the ANN. Furthermore, the method is demonstrated in a way that the PR time series of two modules is evaluated from past weather data.

description: PV module power loss that can occur due to the phenomenon of potential induced degradation (PID) is associated with the transfer of electric charge through leakage currents from the PV cell circuit to earth ground. As the susceptibility of a PV module to PID is related to the amount of charge transferred during its operation, it is crucial to assess this value to estimate the service lifetime of the module. However, standard procedures request a monitoring period of a full year or at least a half year in the actual environment for a representative assessment of the expected charge transfer implying a long testing time and site dependency. Modelling of the PV module leakage currents from data sets of the environmental parameters to predict the charge transfer may allow to reduce this effort. In this examination, Artificial Neural Networks (ANN) have been trained for the modelling of PV module leakage currents. Monitoring data sets of measured leakage current data together with the environmental parameters from a site in temperate climate (Germany) as well as from a site in tropical climate (Singapore) for at least a whole year could be utilized. It showed that the ANN models are well suited for the task and open up opportunities to reduce the outdoor monitoring time and effort required for the assessment of the PID susceptibility of a PV module type in a specified environment.

description: We consider profinite groups as 2-sorted first order structures, with a group sort, and a second sort which acts as an index set for a uniformly definable basis of neighbourhoods of the identity. It is shown that if the basis consists of {\em all} open subgroups, then the first order theory of such a structure is NIP (that is, does not have the independence property) precisely if the group has a normal subgroup of finite index which is a direct product of finitely many compact $p$-adic analytic groups, for distinct primes $p$. In fact, the condition NIP can here be weakened to NTP${}_2$. We also show that any NIP profinite group, presented as a 2-sorted structure, has an open prosoluble normal subgroup.

description: The degradation of a PV module is strongly influenced by moisture ingress. Previously most of the investigations of the diffusion properties of encapsulants and backsheets were carried out on the polymer sheets alone, and thereby not accounting for diffusion properties of all involved materials. In this work, the kinetic study of the water uptake of the EVA was performed inside the laminate stack, using incorporated miniature digital humidity sensors at different EVA depths. Samples with different polymeric materials and lamination conditions were aged under a damp-heat (DH) and UV/DH (combined) conditions while applying an in-situ moisture monitoring technique for PV modules. From this data, we calculated the respective diffusion rates and determined how the different materials and lamination conditions affect the mechanism of moisture ingress/egress during the aging tests. The results demonstrate a faster diffusion in the CPC backsheet than in the TPT backsheet type. With respect to the lamination process, the effective activation energy (EAeff), calculated assuming an Arrhenius-like behavior showed slower moisture ingress for the shortly laminated sample. Furthermore, the effect of the UV irradiation on the diffusion behavior during the combined UV-DH aging test is presented.

description: Inspired by the success of Boltzmann Machines based on classical Boltzmann distribution, we propose a new machine learning approach based on quantum Boltzmann distribution of a transverse-field Ising Hamiltonian. Due to the non-commutative nature of quantum mechanics, the training process of the Quantum Boltzmann Machine (QBM) can become nontrivial. We circumvent the problem by introducing bounds on the quantum probabilities. This allows us to train the QBM efficiently by sampling. We show examples of QBM training with and without the bound, using exact diagonalization, and compare the results with classical Boltzmann training. We also discuss the possibility of using quantum annealing processors like D-Wave for QBM training and application.

description: Photovoltaic module failure modes associated with backsheet degradation have a high relevance in the operation and maintenance of power plants. In this work, field-exposed modules are analyzed by Scanning Acoustic Microscopy (SAM) to visualize and localize backsheet failure modes in specific layers non-destructively. Acoustic micrographs were collected from material depths of the backsheet and allowed the visualization and assessment of depth profiles of the embedded PV module components individually. Multiple types of interlayer cracks were identified. These local defects of the backsheet were validated by microscopy images of destructively acquired backsheet cross-section samples. Additionally, the backsheet cracking are reproduced in laboratory under UV-DH combined aging test.

description: The aim of this work is to analyse the mechanical stability of field aged backsheet laminates based on a PET core layer. A correlation should be established between the occurrence or absence of backsheets cracks and the corresponding elongation at break (EaB). In this study, we evaluated the state of health of backsheets based on a PET core layer after 4 to 10 years of outdoor field exposure. The investigated PV modules were produced by different manufacturers and were taken from European PV power plants for detailed analysis at the ZSW PV test laboratory Solab. After visual inspection and wet leakage current testing, backsheet samples corresponding to the machine direction (MD) and transversal direction (TD) of the polymer extrusion were prepared and subjected to elongation at break tests. In addition, the inner core and outer layers of the backsheet polymer laminates were analysed by surface grinding and consecutive ATR-FTIR spectra measurements.
Insulating phase in Sr$_2$IrO$_4$: An investigation using critical analysis and magnetocaloric effect

description: The nature of insulating phase in 5$d$ based Sr$_2$IrO$_4$ is quite debated as the theoretical as well as experimental investigations have put forward evidences in favor of both magnetically driven Slater-type and interaction driven Mott-type insulator. To understand this insulating behavior, we have investigated the nature of magnetic state in Sr$_2$IrO$_4$ through studying critical exponents, low temperature thermal demagnetization and magnetocaloric effect. The estimated critical exponents do not exactly match with any universality class, however, the values obey the scaling behavior. The exponent values suggest that spin interaction in present material is close to mean-field model. The analysis of low temperature thermal demagnetization data, however, shows dual presence of localized- and itinerant-type of magnetic interaction. Moreover, field dependent change in magnetic entropy indicates magnetic interaction is close to mean-field type. While this material shows an insulating behavior across the magnetic transition, yet a distinct change in slope in resistivity is observed around $T_c$. We infer that though the insulating phase in Sr$_2$IrO$_4$ more close to be Slater-type but the simultaneous presence of both Slater- and Mott-type is the likely scenario for this material.
title: Strukturgrößen zur Schwingfestigkeitsbewertung von Schweißverbindungen

description: Zur Schwingfestigkeitsbewertung wiederholt belasteter Schweißverbindungen können Anwender aus der industriellen Praxis auf Nachweisverfahren wie dem Nenn-, Struktur- und Kerbspannungskonzept zurückgreifen, die unter anderem in den Empfehlungen des International Institute of Welding (IIW) oder der Richtlinie des Forschungskuratoriums Maschinenbau e.V. (FKM) beschrieben sind. Zyklisch hochbeanspruchte geschweißte Bauteile mit Versagen im Kurzzeitfestigkeitsbereich können damit jedoch nicht bewertet werden, da dieser Lebensdauerbereich außerhalb der Anwendungsgrenzen der Regelwerke liegt. Eine auf Schweißverbindungen erweiterte Variante des Örtlichen Konzepts nach der FKM-Richtlinie Nichtlinear schließt diese Lücke. Allerdings erfordert dieses Verfahren ein aufwendig zu erstellendes detailliertes und fein vernetztes Finite-Elemente-Modell der untersuchten Struktur. Alternativ zu dieser Methode wird daher ein auf Strukturspannungen und -dehnungen basierendes "Strukturgrößenkonzept" vorgestellt, dem ein grob vernetztes Modell genügt. Durch die grobe Vernetzung können bei verhältnismäßig kurzen Rechenzeiten elastisch-plastisches Werkstoffverhalten und geometrische Nichtlinearität in der numerischen Rechnung berücksichtigt werden. Dies stellt auch bei hohen Beanspruchungen und größeren Deformationen eine realitätsnahe Simulation des Strukturverhaltens sicher. Zugunsten einer möglichst hohen Akzeptanz in der Praxis wird das Strukturgrößenkonzept an das Strukturspannungskonzept gemäß der FKM-Richtlinie angelehnt. Auf diese Weise lassen sich darin enthaltene praxiserprobte Einflussfaktoren und Handlungsanweisungen unmittelbar oder mit geringfügigen Anpassungen übertragen. Auch die zur Bewertung zyklischer Beanspruchungen erforderlichen Wöhlerlinien werden aus der Richtlinie abgeleitet. Die anschließende Validierung des Nachweisverfahrens und der Vergleich mit der zuvor erwähnten Variante des Örtlichen Konzepts erfolgt auf Basis selbst durchgeführter und in der Literatur beschriebener Ermüdungsversuche. Insgesamt werden hierfür 213 Versuche an Stumpf- und T-Stößen mit Blechdicken von 8 bis 40 mm aus ferritischen sowie austenitischen Stählen mit Fließgrenzen zwischen ca. 200 und 1000 MPa nachgerechnet. Anhand der Gegenüberstellung der rechnerischen und experimentell ermittelten Lebensdauern zeigt sich, dass alle untersuchten Schweißverbindungen im betrachteten Lebensdauerbereich von 10^0 bis 10^6 Lastwechseln mit dem Strukturgrößenkonzept sicher bewertet werden. Dabei sind im Vergleich zum Örtlichen Konzept insbesondere im Kurzzeitfestigkeitsbereich deutlich treffendere Lebensdauerabschätzungen bei zugleich wesentlich geringeren Streuungen zu beobachten.

description: Structural modification of adsorbed overlayers by means of external factors is an important objective in the fabrication of stimuli-responsive materials with adjustable physicochemical properties. In this contribution we present a coarse-grained Monte Carlo model of the confinement-induced chiral self-sorting of hockey stick-shaped enantiomers adsorbed on a triangular lattice. It is assumed that the adsorbed overlayer consists of "normal" molecules that are capable of adopting any of the six planar orientations imposed by the symmetry of the lattice and molecular directors having only one permanent orientation, that reflect the coupling of these species with an external directional field. Our investigations focus on the influence of the amount fraction of the molecular directors, temperature and surface coverage on the extent of the chiral segregation. The simulated results demonstrate that the molecular directors can have a significant effect on the ordering in enantiopure overlayers, while for the corresponding racemates their role is largely diminished. These findings can be helpful in designing strategies to improve methods of fabrication of homochiral surfaces and enantioselective adsorbents.

description: Objectives: To determine the effect of media violence on aggression based anxiety. Method: We conducted a meta-analysis of studies where the effect of media violence on aggression and anxiety was seen on control and experimental groups. The effect size in terms of Cohen’s d was identified or calculated for the studies that qualified for final analysis.Results: A comprehensive search yielded 417 studies; 3 articles met inclusion criteria. Meta-analysis suggests that effect of media violence is positive on aggression based anxiety. The anxiety that stems from the viewing violence in media. Theoretical frameworks like social learning theory also supports the assumptions that exposure to media showing aggression increases the anxiety of people who are exposed. The effect sizes of the included studies are most likely not statistically heterogeneous. A fixed-effects model fits the observed homogeneity in this situation by assuming that all studies are estimating the same underlying population effect.Conclusion: This meta-analysis suggests that exposure to violent media content has been found to have an effect on aggression and anxiety. However, the form of media inflicting such effect is to be studied, also across different populations and age groups. As many of the studies primarily focused on specific populations, such as children and, adolescents, this may limit the generalizability of the findings to broader populations and different cultural contexts.

description: Electrically Conductive Adhesives (ECA) have been used to replace tin-lead solder in the assembly of electronic circuits. To investigate the electrical performance between conductive materials, methods to measure the contact resistivity have been developed and extensively studied in terms of their accuracy and limitations. Studies specifically on ECA-based joints mainly refer to contact resistivity extrapolated using the Transmission Line Method (TLM). The aim of this research work is to further explain and demonstrate how such method can best be used to determine the contact resistivity of ECA-based joints, as well as highlight its limitations when applied to these kinds of systems. Moreover, to show the effects of sample preparation, current sourcing, and data analysis. Results show that TLM in combination with contact end resistance (TLM-CER) is more reliable than TLM. Moreover, the contact resistivity depends on sample geometry and current injection. Further studies will be carried out to improve sample geometry, to study the effect of busbars between fingers and include the Stacked Greek Cross as another method to obtain the contact resistivity.

description: Underwater Solar Photovoltaics have the potential to resolve the necessities of long-term power sources for underwater sensing, monitoring, and low power applications. Even though there are several challenges and limitations, however, our previous studies have demonstrated that submerged Solar cells can generate the required amount of power even with the presence of water impurities. In this work, the submerged amorphous, monocrystalline, and polycrystalline Solar cells, especially the near-infrared spectrum using the long pass glass filter, have been further studied. In order to analyze the performance of the submerged Solar cells with the infrared spectrum, the transmission of Solar radiation in water also studied. Further, the obtained results were compared to our previous studies without using the long pass filter, passing the full spectrum from the Solar simulator.

description: In this study, Light and Elevated Temperature Induced Degradation (LETID) and Potentially Induced Degradation (PID) of heterojunction (HJT) modules and cells sensitivity are tested. LeTID is known to affect PERC modules and some evidences of LeTID in HJT modules have recently been reported. Carrier Induced Degradation and Light Induced Degradation are two different methods to test LeTID sensitivity. Both tests were carried out on modules with PERC and HJT cells. A small loss of 2.5% is pointed out for some PERC modules whereas the HJT modules tested presented no LeTID. Similarly, PID test for 96h shows no loss for HJT modules.

description: This paper considers the problem of maximizing the sum-rate for simultaneous wireless information and power transfer (SWIPT) in a full-duplex bi-directional communication system subject to energy harvesting and transmit power constraints at both nodes. We investigate the optimum design of the receive power splitters and transmit powers for SWIPT in full-duplex mode. Exploiting rate-split method, an iterative algorithm is derived to solve the non-convex problem. The effectiveness of the proposed algorithm is justified through numerical simulations.

description: Due to the insufficient continental areas, PV systems were widely deployed in the coastal regions in Taiwan to achieve the expectation of GW-scale installation in 2025. In contrast to terrestrial deployment, coastal region brings much larger stress to PV modules because of high humidity and heavy concentration of salt and minerals. The premature degradation of the polymer materials and corrosion of metallic interconnections in PV modules might result in power degradation and safety issues. In this study, two groups of modules (A and B) were prepared for cyclic corrosion tests (CCT) refer to test method 7 of IEC 61701:2020. One group (C) were experienced the additional damp heat (DH) and potential induced degradation (PID) tests prior to CCT. The power degradation occurred C1 and C2 modules increased dramatically from 4.4 % to near 9 % after DH test followed by CCT. The significant decrease of open circuit voltage indicated the possibilities of corrosion in interconnections. The electroluminescence (EL) images were used to confirm the corrosion phenomenon. This pre-study of new version of IEC 61701 would provide a foresight for durability evaluation of PV module used in high corrosivity regions.

description: Aging test acceleration for UV durability assessment is the subject of ongoing debates in the PV industry. As both short test duration and natural aging representativeness are needed in the context of an ever-challenging PV development, we explored the possibility to use UV LED-based chambers for accelerated aging applications. To this end, nine encapsulants that belong to four distinct polymer families (EVA, ionomers, POE, TPO) were aged under UV light provided by either xenon, LED or mercury lamps. Samples behavior was analysed through UV-visible transmission measurement. One ionomer showed particularly strong photodegradation of its UV stabilizers, phenomenon that also happens under natural outdoor conditions. Their destruction was accelerated up to 20 times thanks to UV LED very high irradiance (3000 W/m² at 365 nm) in comparison with a standard UV aging test in a xenon chamber. Temperature effect upon photodegradation kinetics was also highlighted. We showed that a raise of 10 °C (55 to 65 °C) led to a 30 % aging acceleration of ionomer’s UV stabilizers. Finally, the influence of UV LED emission wavelength upon the rate of encapsulant photodegradation was studied. When compared to UV aging at 395 nm, irradiation at 305 nm was estimated to accelerate ionomer photodegradation by 80 %. Because of their unique ability to provide very high irradiance while maintaining a moderate temperature, UV LED showed their great potential for UV aging acceleration in the endeavor for faster but still relevant UV durability testing.

description: We use Angle Resolved Photoemission Spectroscopy (ARPES), Raman spectroscopy, Low Energy Electron Diffraction (LEED) and x-ray scattering to reveal an unusual electronically mediated charge density wave (CDW) in K0.9Mo6O17. Not only does K0.9Mo6O17 lack signatures of electron-phonon coupling, but it also hosts an extraordinary surface CDW, with TS CDW =220 K nearly twice that of the bulk CDW, TB CDW =115 K. While the bulk CDW has a BCS-like gap of 12 meV, the surface gap is ten times larger and well in the strong coupling regime. Strong coupling behavior combined with the absence of signatures of strong electron-phonon coupling indicates that the CDW is likely mediated by electronic interactions enhanced by low dimensionality.

description: The encapsulation of photovoltaic (PV) modules insulates solar cells and internal electrical components, and protects them from environmental stresses. Encapsulant delamination is a common mode of failure, and can appear immediately after manufacturing (quality issues) or it can occur over time (degradation). In both cases, the long-term impact of delamination on module performance is poorly quantified. In this work the causes and effects of delamination were examined in greater detail. Inhomogeneities during lamination (e.g. temperature, uncured material composition) form areas with different properties which are expected to be more susceptible to delamination over time. To assess the long-term effect of delamination on performance, single cell c-Si modules with an ethylene-vinyl acetate (EVA) encapsulant and poor lamination quality or selective delamination were manufactured and subjected to a series of accelerated weathering tests (damp heat (DH), thermal cycling (TC), ultraviolet (UV) light). The extent of delamination increased over time, and lead to a higher rate of performance-loss compared to reference modules, for example, more than double in the case of damp heat exposure.

description: Ice-water, water-vapor interfaces and ice surface are studied by molecular dynamics simulations with the SPC/E model of water molecules having the purpose to estimate the profiles of electrostatic potential across the interfaces. We have proposed a methodology for calculating the profiles of electrostatic potential based on a trial particle, which showed good agreement for the case of electrostatic potential profile of the water-vapor interface of TIP4P model calculated in another way. The measured profile of electrostatic potential for the pure ice-water interface decreases towards the liquid bulk region, which is in agreement with simulations of preferential direction of motion of Li$^{+}$ and F$^{-}$ solute ions at the liquid side of the ice-water interface. These results are discussed in connection with the Workman-Reynolds effect.

description: Recent studies showed that SHJ solar cells can be prone to PID when encapsulated with a low volume resistivity encapsulant, such as ethylene vinyl acetate (EVA). These studies also demonstrated that their degradation mechanism is different from Al-BSF modules. It is well known that PID in Al-BSF cells can be prevented by a high volume resistivity encapsulant. In this work we perform PID tests in humid conditions (85°C/85% RH) on one-cell SHJ glass/glass modules with and without edge sealant. Seven different encapsulants are used: ionomer, three elastomer polyolefin (POEs), thermoplastic polyolefin (TPO), polyvinyl butyral (PVB) and EVA. Moreover, the effect of water ingress and the voltage polarization are also considered. The results indicate that PID can be prevented with the proper selection of encapsulants. Ionomer, POEs and TPO show beneficial effects on preventing degradation, both with and without edge sealant. Modules encapsulated with EVA do not suffer from PID when encapsulated with an edge seal configuration, even after extended tests (e.g. five times the 96 h of test duration foreseen in the IEC Technical Specification for c-Si modules).

description: We present photometry of the intermediate polar FO Aquarii obtained as part of the K2 mission using the Kepler space telescope. The amplitude spectrum of the data confirms the orbital period of 4.8508(4) h, and the shape of the light curve is consistent with the outer edge of the accretion disk being eclipsed when folded on this period. The average flux of FO Aquarii changed during the observations, suggesting a change in the mass accretion rate. There is no evidence in the amplitude spectrum of a longer period that would suggest disk precession. The amplitude spectrum also shows the white dwarf spin period of 1254.3401(4) s, the beat period of 1351.329(2) s, and 31 other spin and orbital harmonics. The detected period is longer than the last reported period of 1254.284(16) s, suggesting that FO Aqr is now spinning down, and has a positive $\dot{P}$. There is no detectable variation in the spin period over the course of the K2 observations, but the phase of the spin cycle is correlated with the system brightness. We also find the amplitude of the beat signal is correlated with the system brightness.
