description: Topological chaos has emerged as a powerful tool to investigate fluid mixing. While this theory can guarantee a lower bound on the stretching rate of certain material lines, it does not indicate what fraction of the fluid actually participates in this minimally mandated mixing. Indeed, the area in which effective mixing takes place depends on physical parameters such as the Reynolds number. To help clarify this dependency, we numerically simulate the effects of a batch stirring device on a 2D incompressible Newtonian fluid in the laminar regime. In particular, we calculate the finite time Lyapunov exponent (FTLE) field for three different stirring protocols, one topologically complex (pseudo-Anosov) and two simple (finite-order), over a range of viscosities. After extracting appropriate measures indicative of both the amount of mixing and the area of effective mixing from the FTLE field, we see a clearly defined Reynolds number range in which the relative efficacy of the pseudo-Anosov protocol over the finite-order protocols justifies the application of topological chaos. More unexpectedly, we see that while the measures of effective mixing area increase with increasing Reynolds number for the finite-order protocols, they actually exhibit non-monotonic behavior for the pseudo-Anosov protocol.

description: Luminescence images of solar cells show material- and process-related defects in solar cells, which are relevant for monitoring, optimization and processing. Convolutional neural networks (CNNs) allow the reliable segmentation of these defects in images of the solar cells. Nevertheless, the training of CNNs requires a large amount of empirical data, in which the defects have to be labeled expensively by experts. We introduce a method allowing efficient training by using Smart Labels. We show how this technique can be used for process monitoring to detect systematic errors. This approach differs from previous methods, which rely on human heuristics in the form of feature engineering or learning-based methods with human-annotated defects. However, this previous approach has some limitations and risks. These include label mistakes due to overlapping defect structures, poorly reproducible annotations and varying label quality. Furthermore, existing algorithms have to be adapted to new cell lines or a new labeling process is required. We overcome these challenges by avoiding the use of human labels and instead perform the CNN training on the basis of spatially resolved reference measurements, which allows us to calculate spatially resolved labels in less than a second. This purely data-driven approach allows a fast training to quantify defects with physical relevance regarding dark saturation current density (0) and series resistance ( ). The trained CNN achieves a precision of 88% and a recall of 91% for 0 defects while for defects it attains a precision of 78% and a recall of 86%. The accelerated training process allows a fast deployment of deep learning models in the solar cell line.

description: In this paper we consider the notion of strong $I$-statistically pre-Cauchy double sequences in probabilistic metric spaces in line of Das et. al. [6] and introduce the new concept of strong $I^*$-statistically pre-Cauchy double sequences in real line as well as in probabilistic metric spaces. We mainly study inter relationship among strong $I$-statistical convergence, strong $I$-statistical pre-Cauchy condition and strong $I^*$-statistical pre-Cauchy condition for double sequences in probabilistic metric spaces and examine some basic properties of these notions.

description: Flatbed screen printing is still the dominant metallization technique for Si-solar cells because it proved to be reliable and cost effective while maintaining to be innovative. The latest reductions of printed Ag-electrode width in the range of 20 µm were mainly driven by further screen optimization. Screen printing pastes have evolved accordingly in order to maintain sufficient contacting behavior at narrow line widths. Our previously published screen simulation model allows to create a virtual representation of any screen opening based on the common screen parameters mesh count, wire diameter, screen angle and opening width. In this work, we discuss its implication by establishing the dimensionless parameter screen utility index SUI which quantifies the compromise between screen stability and opening structure for a sufficient printability. We further show how this parameter has evolved over the last decade for printing experiments conducted at Fraunhofer ISE and discuss what challenges this trend will create for the future of screen printed metallization. Finally, we combine requirements for screen tension, screen utility and reproducibility of finger geometry by applying the deviation of the screen opening rate in a single diagram to visualize the trade-off regarding future screen design.

description: A small amount of Fe (5% and 7.5%) substitution in the Cr-site of the multiferroic compound CoCr2O4 leads to a magnetization reversal. In these compounds, we report a sign change in the exchange bias across the compensation temperature, accompanied by a non-monotonic change in the local moments across the compensation temperature. Such non-monotonic change in the magnetic moments is triggered by a similar change in the lattice structure. We relate here the sign change of exchange bias with that of the crystalline energy of the lattice and the Zeeman energy term arising from the anti-site disorder.

description: With the innovation of cell technology, the conversion efficiency is also continuously improved, but at this same time, it also brings the new degradation Issues. One of the damage modes concerned in Czochralski p-type monocrystalline PERC solar cells is light-induced degradation(LID). The mechanism of LID is shown to be highly related to the formation of B-O complexes, which will lead to approximately 4-6% reduction of power output for PERC cells. Another one is light- and elevated temperature-induced degradation (LeTID). Thus, the evaluation of LID and LeTID become an urgent issue to be solved for solar industries.

description: We present the results of ALMA band 7 observations of dust and CO gas in the disks around 7 objects with spectral types ranging between M5.5 and M7.5 in Upper Scorpius OB1, and one M3 star in Ophiuchus. We detect unresolved continuum emission in all but one source, and the $^{12}$CO J=3-2 line in two sources. We constrain the dust and gas content of these systems using a grid of models calculated with the radiative transfer code MCFOST, and find disk dust masses between 0.1 and 1 M$_\oplus$, suggesting that the stellar mass / disk mass correlation can be extrapolated for brown dwarfs with masses as low as 0.05 M$_\odot$. The one disk in Upper Sco in which we detect CO emission, 2MASS J15555600, is also the disk with warmest inner disk as traced by its H - [4.5] photometric color. Using our radiative transfer grid, we extend the correlation between stellar luminosity and mass-averaged disk dust temperature originally derived for stellar mass objects to the brown dwarf regime to $\langle T_{dust} \rangle \approx 22 (L_{*} /L_{\odot})^{0.16} K$, applicable to spectral types of M5 and later. This is slightly shallower than the relation for earlier spectral type objects and yields warmer low-mass disks. The two prescriptions cross at 0.27 L$_\odot$, corresponding to masses between 0.1 and 0.2 M$_\odot$ depending on age.

description: The International Technology Roadmap for Photovoltaics (ITRPV) is a leading roadmap in the PV community. Ever since its first edition has been published in 2010, the ITRPV has succeeded to provide the technology projections in crystalline silicon PV technology covering a wide scope in the PV value chain. The projection data obtained from contributing experts and institutions are processed and published by the German Mechanical Engineering Industry Association (VDMA). In this paper, the projection accuracy of each of eight frequently reported projected topics is studied. The projected topics include: (a) multicrystalline silicon (mc-Si) wafer thickness, (b) mc-Si ingot mass, (c) bulk recombination current density, (d) emitter sheet resistance, (e) finger width, (f) silver amount per cell, (g) screen printing throughput rate, in addition (h) the market share of half cells is studied. The method includes the calculation of the deviation of each year’s projection from the reference value for each of the chosen topics. Projection absolute percentage deviations (PAPD) are calculated as the time-dependent projection accuracy measure. Based on this approach, finger width projections show the highest accuracy by having a PAPD as a function of time accuracy slope of (1.5 ± 0.1) %/year. Half cells’ market share is the least accurately projected topic featuring a PAPD accuracy slope as a function of time to be (8.1 ± 0.2) %/year. Results of the accuracy study (results of the “past”) provide insights for future expected values.

description: For topological insulators and topological crystalline insulators (TCIs), their exotic surface states are promising for fundamental condensed matter physics research as well as future electronics such as low-dissipation electronics and spintronics. However, the high bulk carrier density that often dominates the transport property is the major materials challenge, critically hindering our ability to study and manipulate the surface states. In this manuscript, we demonstrate an alloying strategy, SnSexTe1-x, to effectively reduce the bulk carrier density. As long as SnSexTe1-x remains in the cubic crystal structure, it is predicted to be a TCI. We show systematic decrease of the bulk carrier density with the increasing Se concentration, demonstrating that the alloying principle works. In addition, we map out the phase diagram of the cubic to the orthorhombic structural transition as a function of the Se concentration. This was made possible by studying alloy nanoplates which remain single-crystalline and is either in the cubic or the orthorhombic phase, in contrast to bulk alloys that would exhibit polycrystalline grains. Lastly, we investigate systematically the ferroelectric transition associated with the structural transition from the cubic to the rhombohedral phase for SnSexTe1-x. This is the first ferroelectric transition study of the alloy system SnSexTe1-x.

description: High-intensity illumination treatments are a versatile method to reduce the performance loss of solar cells due to LeTID since they can be applied at any point of time between cell fabrication and module assembly. We evaluate the potential of these treatments using a true inline treatment tool and commercially available PERC solar cells. To test the stability of cell performance after the treatments, the cells were exposed to 0.15 suns and 75 °C at open circuit. These conditions are close to a recent testing standard suggestion and allow estimating the cell stability over the typical operating lifetime of solar modules. The results show that there is a window of process parameters which improves the stability of solar cell efficiency without compromising the efficiency immediately after the treatment, i.e. before the stability test. The treatments result in an estimated gain of ~ 3 % in the amount of energy produced by the cells during the operating lifetime of a solar module, corresponding to a reduction of LeTID-related energy yield losses by up to ~ 50 %. Importantly, this gain is achievable with belt speeds compatible with high throughput inline processing.

It includes the application of investigated technologies into potential future cell designs such as PERT and bifacial solar cells. The joint project was merged from two individual project suggestions and therefore had two parts. This paper focuses on an industrial solution to minimize the negative impact of light induced degradation (LID) by: • Investigating and understanding the nature of the degradation effect • Applying the experimental results and concepts to industrially suppress LID • Developing an optimized integrated firing-regeneration process for industrial application The second part of this project is also covered in this conference [1].

description: In this paper, two laser-assisted separation processes (i) laser scribe and mechanical cleaving (LSMC) and (ii) thermal laser separation (TLS) for the separation of p-type silicon shingled passivated edge, emitter and rear (pSPEER) solar cells are examined. Both separation processes involve two process steps, where one of them is considered the main laser process that is conducted along the whole separation path (laser scribe for LSMC and laser cleave for TLS). We analyze the influence of the main laser process as well as the complete separation process of both, LSMC and TLS, on the electrical performance of pSPEER solar cells. We include an investigation of the dependency on the separation side, i.e. emitter (front side) or emitter-free side (rear side). It is found that by conducting the LSMC process from the front side, a significantly lower energy conversion efficiency by = -1.9%abs in comparison to the rear side process is observed which originates in particular from a lower pseudo fill factor pFF = -7.5%abs. This is attributed to local ablation of the p-n-junction leading to increased j02-like recombination. By conducting the laser scribe without subsequent mechanical cleaving of host cells, we measure pFF = -9.1%abs in comparison to the initial host cell measurement. This indicates that the laser ablation process itself leads to the strong pFF and losses observed after LSMC separation of pSPEER cells. In comparison, the TLS process is found to be invariant to the processed cell side. It is shown that in this case, the involved laser cleave process itself has no measurable impact on the performance of unseparated host cells.

Within a first experiment, multicrystalline Silicon (mc-Si) PERC solar cells metallized on the rear side with rotary screen printed obtained a mean conversion efficiency of = 19.3 % which is on the same level as reference cells with standard flatbed screen printed rear side metallization ( = 19.3 %). Furthermore, a 9 cell demonstrator module with cells partly metallized on the demonstrator and SmartWire (SWCT) interconnection is presented.

We study the algebraic structure of this graph. The relations for the algebra generated by the graph are derived. In the limiting case $θ=\pm1$ the graph becomes abelian and degenerates into the direct sum of four one-dimensional irreducible representations of the Klein group.

description: This study will use a functional proteomic approach to examine the active kinome in the hippocampus. The active kinome is the global activity of all protein kinases in a system. The hippocampus is subject to dynamic change based on regulatory needs within the system and can therefore contribute to neuroplasticity at a cellular level. The hippocampus has distinct subfields (DG, CA1, CA2, CA3, CA4) and plays a major role in learning and memory. The hippocampal subfields are discrete and have distinct anatomy. Thus, we hypothesize that each subfield has a unique active kinome profile. Differential protein kinase regulation may be essential for molecular plastic changes within the brain. This plasticity is vital for cognitive ability.
 By identifying the protein kinase activity in each hippocampal subfield, comparisons can be made between subkinomes to better understand signaling pathways associated with memory and learning within the brain. The subfields will be isolated via laser capture microdissection (LCM) and run on the PamGene kinome array. Analysis of the array data will be performed using bioinformatic pipelines. Bioinformatic analyses will identify the kinase activity profiles enriched in different hippocampal subfields . The pipelines used in kinomic analysis are Upstream Kinase Analysis (UKA) and Kinome Random Sampling Analyzer (KRSA). Additionally, pathways will be visualized using Bayesian Network Modeling (KINNET). Hippocampal subfield specific pathways will also be generated. The key kinases investigated and the pathways they belong to will then be compared and contrasted between subfields to paint a clearer picture of how they communicate with one another. These studies will extend our knowledge of signalling mechanisms in the hippocampus and provide a roadmap for interrogating the hippocampus in discrete subfields.

description: In our contribution, we evaluate two variants of a bifacial-ready contacting solution for busbarless and multibusbar solar cells with regard to their lifetime and the effect of repeated contacting on a single cell. Our contact solution is named universal contact probes (cetisPV-CF-ucp) as they are universally applicable to all kinds of silicon solar cells. We assess their lifetime using the stability and reproducibility of IV and EL measurements during a long-term test over 8 million contacting cycles. Our results demonstrate a strong impact of the surface morphology of the probes on the contacting quality achievable in the long-term test. Variant two of the probes achieves stable FF measurements and fulfills industry requirements on repeatability and accuracy over a lifetime of 8 million cycles, whereas variant one which differs only in the surface morphology of the contacting area fails after a few hundred thousand cycles. To investigate the effect of repeated contacting on solar cells we examined visible marks left in the cell metallization and electrical degradation upon frequent contacting determining the usability of cells as calibration references over a larger number of contacting events (up to 106 cycles). In the end, we provide a method for a reliable and fast assessment of the local and global contacting quality of each probe bar during maintenance and commissioning.

description: Selective emitter approach has been developed and well quantified to overcome the electrical performance limits in conventional screen-printed solar cells. Among different methods for creating a selective emitter pattern, laser doping might be the most suitable for mass production due to its simplicity. Moreover, instead of using screen-printing paste contacts, SE allows narrower fingers growing on via plating metallization thereby may further reduce the shading loss. Replacing expensive silver with plated copper significantly reduces the cell manufacturing cost. However, the plating quality could be strongly influenced by the cell surface conditions after laser doping. In general, to make an appropriate plating surface, the laser doping should perfectly remove the dielectrics above the silicon, effectively diffuse the dopants with negligible damage, and result in a smooth surface to allow uniform nucleation of metal during the plating process. UV laser (355nm) and green laser (532nm) are two common wavelengths used in laser doping. Two types of laser sources have different advantages and drawbacks. In this paper, we studied the effect of using different wavelengths laser to make bifacial Ni/Cu plated LDSE solar cell. It was found HF pretreatment conditions play the key role in improving the contact formation on different laser doping processing selective emitters. Critical contact properties such as contact adhesion, contact resistance and contact recombination have been systemically evaluated. This finding highlights the importance of dopant activation in plating metallization. Furthermore, it suggests the plating metallization could be less limited by the doping profile as well as thermal damage. This work provides a useful guideline, from laser doping surface morphology, dopant activation requirement to plating conditions, for those aiming to make use of plating metallization on either n-type or p-type surface.

description: The nature and origin of the asteroids orbiting in near-Earth space, including those on a potentially hazardous trajectory, is of both scientific interest and practical importance. We aim here at determining the taxonomy of a large sample of near-Earth (NEA) and Mars-crosser (MC) asteroids and analyze the distribution of these classes with orbit. We use this distribution to identify their source regions and to study the strength of planetary encounters to refresh asteroid surfaces. We measure the photometry of these asteroids over four filters at visible wavelengths on images taken by the SDSS. These colors are used to classify the asteroids into a taxonomy consistent with the widely used Bus-DeMeo taxonomy based on spectroscopy. We report here on the taxonomic classification of 206 NEAs and 776 MCs determined from SDSS photometry, representing an increase of 40% and 663% of known taxonomy classifications in these populations. Using the source region mapper by Greenstreet et al. (2012), we compare the taxonomic distribution among NEAs and main-belt asteroids of similar diameters. Both distributions agree at the few percent level for the inner part of the Main Belt and we confirm this region as a main source of near-Earth objects. The effect of planetary encounters on asteroid surfaces are also studied by developing a simple model of forces acting on a surface grain during planetary encounter, which provides the minimum distance at which a close approach should occur to trigger resurfacing events. By integrating numerically the orbit of the 519 S-type and 46 Q-type asteroids back in time and monitoring their encounter distance with planets, we seek to understand the conditions for resurfacing events. The population of Q-type is found to present statistically more encounters with Venus and the Earth than S-types, although both types present the same amount of encounters with Mars.

description: We demonstrate automated generation of diffusion databases from high-throughput density functional theory (DFT) calculations. A total of more than 230 dilute solute diffusion systems in Mg, Al, Cu, Ni, Pd, and Pt host lattices have been determined using multi-frequency diffusion models. We apply a correction method for solute diffusion in alloys using experimental and simulated values of host self-diffusivity. We find good agreement with experimental solute diffusion data, obtaining a weighted activation barrier RMS error of 0.176 eV when excluding magnetic solutes in non-magnetic alloys. The compiled database is the largest collection of consistently calculated ab-initio solute diffusion data in the world.

description: In this study, we investigate and demonstrate the general feasibility of a new approach for a self-aligned selective emitter process technology for passivated emitter and rear cell (PERC) technology based on inkjet printing of an UV-polymer ink in combination with plating for metallization. First, we present the major findings about the single process development of inkjet printing (minimum printed structures of 36 μm), emitter etch-back (from Rsh = 80 Ω/sq to 144 Ω/sq with an etch time of 10 s), low temperature passivation (depositions temperatures of up to 250°C), a lift-off process (at elevated temperatures of 600°C) and demonstrate that the UV-polymer ink shows sufficient chemical and thermal stability to the processes involved. Finally, the successful integration into the PERC process sequence with upscaling to an industrial wafer size M2 and a first working cell device with an efficiency = 19.68% is demonstrated. In comparison, a conventional mask&etch selective emitter approach using inkjet printing of an hotmelt ink in combination with a semi-automated enhanced alignment algorithm between inkjet and screen printing is processed in parallel showing = 21.54% and a gain of = 0.16%abs compared to PERC cell with homogeneous emitter.

description: In this work, we investigate an approach of shortened low pressure (LP) POCl3 diffusion and a high throughput thermal oxidation with stacked wafers to form the emitter for passivated emitter and rear cells (PERC). As the high temperature processes such as LP-POCl3 diffusion and thermal oxidation account for a significant share of the manufacturing costs of PERC solar cells, our high throughput approach is very promising in terms of reducing both, production costs and energy consumption. Compared to state-of-the-art POCl3 diffusion and low temperature oxidation, a 40% reduction of the specific costs and a 50% reduction of the energy consumption of the high temperature processes is feasible. We examine this approach by using four different adapted LP-POCl3 diffusion processes using only the deposition phase (omitting further drive-in and in-situ oxidation) in combination with a “stack oxidation” process. Detailed characterization of the properties of the emitter and oxide layers after diffusion and after oxidation confirm a high quality emitter formation resulting in emitter dark saturation current density j0e ≈ 32 fA/cm2 at Rsh ≈ 183 Ω/sq. Although the wafers are oxidized in a stack of horizontally oriented wafers touching each neighboring wafer, a very homogeneous oxide grows resulting in high passivation quality. Further, we find that this adapted emitter diffusion process allows for effective laser doping, which is promising for selective emitter formation.

description: In this work, we investigate the emitter sheet resistance and emitter recombination current density by optimizing the POCl3emitter diffusion process parameters to achieve improved electrical properties and cell performance. Wafers used in the experiment were boron-doped p-type mono-crystalline silicon samples, nanotextured in an atmospheric pressure dry etching tool (ADE) producing highly textured surfaces and decreased surface reflection. Surface roughness is subsequently reduced by a short isotropic etch, to facilitate the surface passivation. The optimization of the diffusion process is realized by adjusting the phosphorus deposition temperature and its drive-in duration, resulting in decreased emitter saturation current density of ~100 fA/cm2 and in more homogeneous emitter sheet resistance of ~105 Ω/sq. Compared to the un-optimized diffusion process, it also leads to a decreased Auger recombination.

description: Soft membranes are commonly employed in shape-morphing applications, where the material is programmed to achieve a target shape upon activation by an external trigger, and as coating layers that alter the surface characteristics of bulk materials, such as the properties of spreading and absorption of liquids. In particular, polymer gel membranes experience swelling or shrinking when their solvent content change, and the non-homogeneous swelling field may be exploited to control their shape. Here, we develop a theory of swelling material surfaces to model polymer gel membranes and demonstrate its features by numerically studying applications in the contexts of biomedicine, micro-motility, and coating technology. We also specialize the theory to thermo-responsive gels, which are made of polymers that change their affinity with a solvent when temperature varies.

description: In photovoltaic industry, wet chemical processes are commonly used for surface structuring and cleaning purposes. The process of wet chemical emitter etch back in hydrofluoric acid (HF), hydrochloric acid (HCl) and ozone (O3) is a promising option in the formation of selective emitters, as the etch back is combined with a cleaning effect. However, surface inhomogeneities were shown in a previous work. In this work an approach for a multiphysics simulation of the emitter etch back process over a full wafer surface is made, taking into account fluid dynamics as well as reaction modeling. A microscopic two dimensional (2D) model is stepwise extended to a full industrial wafer length. Validation experiments enable an estimation of unknown parameters via parameter studies. At higher O3 concentrations simulation results are in good agreement with validation data. The developed reaction model is then transferred to a three dimensional (3D) model, to simulate etching depths over a full wafer surface. Similar mean etching depths of simulation (8.67±0.22 nm) and experiment (9.02±1.10 nm) are obtained. The model can be used as a basis for future work to enable an effective process optimization. For instance, to simulate effects as a result of parameter changes like plant design or etchant composition.

description: Usually, the three-tangle of a tripartite pure state of qubits can be directly measured with the simultaneous preparation of a not-less-than-four-fold copy of the state. We show that the exact genuine tripartite entanglement for ($2\otimes2\otimes n$)-dimensional pure quantum states can be measured in a similar manner, provided that only two simultaneous copies of the state are available. Lower bounds are also proposed for more convenient experimental operations. As an example, a comprehensive demonstration of the scheme is provided for the three-tangle of a three-qubit state.
