description: In this work, we investigate two approachesfor high throughput emitter formation and thermal oxidation for passivated emitter and rear cells (PERC). The low temperature stack oxidation (LoTSOx) approach uses wafer stacks in the typical low temperature thermal oxidation process in the PERC manufacturing sequence. With the LoTSOx approach, we reach similar energy conversion efficiencies of = 22.2% in comparison to state-of-the-art PERC processing but with 3.1 times higher throughput. The second approach, using a shortened low pressure POCl3 diffusion and a high temperature stack oxidation (HiTSOx approach) with laser-doped selective emitter, yields a peak conversion efficiency of = 22.0% and low specific contact resistances c ≈ 0.6 mΩcm2. We further investigate different diffusion and oxidation processes for the HiTSOx approach resulting in a wide range of emitter sheet resistances Rsh. We reach low emitter dark saturation current densities of j0e = 12 fA/cm2 at Rsh = 389 Ω/sq while stacking the wafers during the oxidation process.

description: We introduce a modelling and simulation framework for cell aggregates in three dimensions based on interacting active surfaces. Cell mechanics is captured by a physical description of the acto-myosin cortex that includes cortical flows, viscous forces, active tensions, and bending moments. Cells interact with each other via short-range forces capturing the effect of adhesion molecules. We discretise the model equations using a finite element method, and provide a parallel implementation in C++. We discuss examples of application of this framework to small and medium-sized aggregates: we consider the shape and dynamics of a cell doublet, a planar cell sheet, and a growing cell aggregate. This framework opens the door to the systematic exploration of the cell to tissue-scale mechanics of cell aggregates, which plays a key role in the morphogenesis of embryos and organoids.

High Temperature Route for Si Cells

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 135-139
description: We present a lean POLO IBC solar cell process flow using p-type Cz silicon wafers, where a local SiOxNy/n-poly-Si emitter is formed by PECVD-deposition of SiOxNy/n-a-Si through a glass-based shadow mask followed by a subsequent thermal anneal. Light microscope measurements confirm that the PECVD SiOxNy/n-a-Si pattern deposited on the Cz wafer matches the IBC glass shadow mask layout. A parasitic deposition extending ~60 µm per edge below the mask can occur. However, by an appropriate post-treatment, the parasitic deposition can be reduced to below 5 µm across the whole wafer. On IBC solar cell precursors with two-sided polished surfaces fabricated using the local PECVDdeposition of SiOxNy/n-a-Si we obtain a median implied open circuit voltage (iVoc) of 709 mV which is comparable to parallel processed samples using a wet-chemical interfacial oxide grown in DI/O3 plus PECVD n-a-Si with a median iVoc value of 705 mV. After further process optimization including introduction of a post-anneal cleaning step for improved AlOx/SiNx passivation the IBC cell precursors with textured front exhibit an excellent median implied Voc of 738 mV. These results show the principal feasibility of the POLO IBC process flow presented.

description: Pregnancy and being mother has been taken into account as an enjoyable and evolutionary event in the women's life, however, due to Physiological and Psychological changes; it can be associated with Anxiety and Depression. This study aimed to investigate the Mediating Role of Self-Compassion in the Relationship between Body Image and Severity of Anxiety and Depression in Pregnant Women. The research method was Non-Experimental and Correlational. The research population consisted of all pregnant women who were in their third trimester of pregnancy and referred to health centers of Tehran hospital for pregnancy care. A sample of 140 pregnant women was selected using convenience sampling from three Hospitals of Quds, Hedayat and Alghadir. To collect data, Neff Self-Compassion scale (2003), Pregnancy Related Anxiety Questionnaire (1990), Edinburgh Postnatal Depression Scale (1987) and Body Image in Pregnancy Scale (2017) were used. Pearson's correlation coefficient and Hayes PROCESS procedure extension in Regression analysis were used to analyze the data. The results of Pearson's correlation showed that Body image had a significant positive correlation with the severity of Anxiety and Depression and self-compassion had a significant negative correlation with body image, anxiety and depression (P<0.01). The results of Multiple Linear Regression confirmed the mediating role of self-compassion in the relationship between body image and the severity of anxiety and depression in pregnant women (R2=0/33, P<0.01). According to the finding, it's recommended to pay serious attention to increasing self-compassion and reducing body image dissatisfaction in health care planning to improve the mental health of pregnant women.

description: For silicon solar cells, screen-printing has long been favored by the manufacturers due to its simplicity and high throughput. Over decades of technology advancement, screen-printing has almost pushed to its material and equipment limits (e.g. high-aspect ratio of finger, material impacts on cell etc.). However, in recent years, the increasing silver prices, reducing wafer thickness, and emerging new cell designs continue introducing challenges to this mature technology. Those issues have provided incentives to seek metallization alternatives. Among various metallization techniques, Ni/Cu plated contacts could be the most promising candidate due to its scaling up potential. However, there has been a delay of market share increase versus the ITRPV predication. The lack of readily available appropriate equipment and process standard could be the key reason to cause this. Here, we presented the developing UNSW bifacial plating technology. The special designed industrial prototype has greatly improved the plating uniformity and product stability. Moreover, double sides of the cell could be simultaneously plated thereby effectively reducing the processing time. In this paper, the design consideration and engineering solutions were plainly reviewed. The robust cell metallization process has been demonstrated on 6-inch industrial bifacial PERC precursors and primary intergraded with hydrogenation technology successfully. Despite that, this plating prototype could also be applied on other cell structures such as TOPCon, HJT and tandem structure. This innovative technology would remarkably optimize the processing engineering of plating metallization and may promote the utilization of plated contacts in solar cells manufacturing.

description: The CLARITY method renders brains optically transparent to enable high-resolution imaging in the structurally intact brain. Anatomically annotating CLARITY brains is necessary for discovering which regions contain signals of interest. Manually annotating whole-brain, terabyte CLARITY images is difficult, time-consuming, subjective, and error-prone. Automatically registering CLARITY images to a pre-annotated brain atlas offers a solution, but is difficult for several reasons. Removal of the brain from the skull and subsequent storage and processing cause variable non-rigid deformations, thus compounding inter-subject anatomical variability. Additionally, the signal in CLARITY images arises from various biochemical contrast agents which only sparsely label brain structures. This sparse labeling challenges the most commonly used registration algorithms that need to match image histogram statistics to the more densely labeled histological brain atlases. The standard method is a multiscale Mutual Information B-spline algorithm that dynamically generates an average template as an intermediate registration target. We determined that this method performs poorly when registering CLARITY brains to the Allen Institute's Mouse Reference Atlas (ARA), because the image histogram statistics are poorly matched. Therefore, we developed a method (Mask-LDDMM) for registering CLARITY images, that automatically find the brain boundary and learns the optimal deformation between the brain and atlas masks. Using Mask-LDDMM without an average template provided better results than the standard approach when registering CLARITY brains to the ARA. The LDDMM pipelines developed here provide a fast automated way to anatomically annotate CLARITY images. Our code is available as open source software at http://NeuroData.io.

description: A novel contacting system with Flexible Spring Suspension (FSS) has been developed. The system is optimized for the current-voltage (I-V) curve measurement of busbar-less silicon solar cells and is also suitable for other structures such as multi-busbar and shingled solar cells. It is equipped with independent current and voltage contacts on the fingers, in order to achieve ideal 4-wire connection. The contacting structures of the FSS4 consist of multiple small reed-shaped strips, thereby realize more secure and reproducible contact to the fingers with low contact resistance than conventional pin probes. Excellent reproducibility of relative ±0.05% or better in the Isc, Voc, Pmax, and FF has been confirmed for 20 times of dynamic testing of a 6-inch busbar-less cell, which includes mounting/unmounting of the cell to the sample stage and connecting/removing of the FSS4 system to the cell. Undesirable damages to the fingers and cells during the measurements are minimized by the FSS4, because of its innovative structure where each strip has perpendicular contact to the fingers by monolithic plate spring suspentions, and also its line contact to the fingers. It also has an excellent mechanical durability of over 10 million times. In the actual production line conditions, reliability of 4 million times is expected, which enabling low-cost and reproducible production. tual production line conditions, reliability of 4 million times is possible, which enables low-cost and accurate production.

description: Efficiencies surpassing 26% have been achieved for single-junction Si solar cells based on the interdigitated back contact (IBC) architecture. However, the possibility of lateral shunting between the doped fingers has limited industrial adoption thus far. To avoid this possibility of shunt, complicated patterning techniques of the doped rear fingers have been developed, but spreading can still occur through multiple pathways during cell processing. Patterning can be simplified by using masked plasma-enhanced chemical vapor deposition (PECVD), but spreading during deposition will also lead to contamination of the isolation region between doped fingers. We significantly reduce the effect of this spreading through a short, gentle plasma etching step, which enables a trap-assisted compensation mechanism to take effect more easily than without the plasma etch. These two effects combined allow for the use of a simple patterning technique while still maintaining a highly resistive region between the doped fingers, and will reduce the complexity of IBC cell fabrication overall.

description: We have studied the crystal and magnetic structures of Fe-doped hexagonal manganites LuMn1-xFexO3 (x = 0, 0.1, 0.2, and 0.3) by using bulk magnetization and neutron powder diffraction methods. The samples crystalize consistently in a hexagonal structure and maintain the space group P63cm from 2 to 300 K. The Néel temperature TN increases continuously with increasing Fe-doping. In contrast to a single Γ4 representation in LuMnO3, the magnetic ground state of the Fe-doped samples can only be described with a spin configuration described by a mixture of Γ3 (P63'cm') and Γ4 (P63'c'm) representations, whose contributions have been quantitatively estimated. The drastic effect of Fe-doping is highlighted by composition-dependent spin reorientations. A phase diagram of the entire composition series is proposed based on the present results and those reported in literature. Our result demonstrates the importance of tailoring compositions in increasing magnetic transition temperatures of multiferroic systems.

As urgent R&D topics are suggested: how thermal history and injection density affect LeTID degradation of Ga-doped cells; material and processing sequence to produce transparent passivating contacts, both for PERC and TOPCon cells and HJT cells; it is important that the cells and transparent passivating contacts are free of scarce elements such as indium, otherwise the cell type cannot contribute significantly to meeting the Paris Climate Agreement due to planetary boundaries; possibly replacing silver with copper or aluminum is the most urgent task ahead of PV scale-up and much needed CO2 mitigation.

description: We show how at Q CELLS, interpretable machine learning algorithms are used to understand the energy conversion efficiencies of mass-produced p-type Cz-Si solar cells. For this end, we use the data of a one week ramp-up of over half a million cells acquired utilizing a single-wafer tracking system. These consist of over 300 single information per cell and feature inline measurements, path- and tool related information, process data as well as the final I-V characteristics. In the analysis using state-of-the-art machine learning algorithms, we focus on understanding how the many different input features influence the solar cell efficiency over time by using additive feature impacts. As sources of variation are spread over several features, we pay special attention to correlated features in a hierarchical clustering approach. Finally, after ensuring the model validity at the hands of a hold out test data set (Pearson’s coefficient of correlation of 0.84 between true and predicted values), subtle hourly cell efficiency fluctuations in the order of 0.01%abs are explained. We identify features which are relevant for short-term changes in the efficiency and other which influence the efficiency on a general level and do not show temporal changes.

description: Zinc oxide (ZnO) is one of the widely studied and promising candidates in multidisciplinary research areas including, but not limited to optoelectronics and advance materials physics. However, the unique characteristics can be further twisted using alien acceptors or donors doping. Here in this work, we have devised a simple and onestep process to fabricate Copper (Cu)-doped ultrathin ZnO film through a co-sputtering technique. The weight percentage of Cu was varied from 50% to 100% to 150% with respect to the reference specimen. A set of topographical, optical and electrical characterizations was carried out to understand the characteristic of Cu-doped ZnO (ZnO:Cu) thin films using various techniques, such as FESEM, UV-absorption and transmission. The same layer was integrated with a standard solar cell and the performances of the overall solar cell were evaluated using a solar simulator. Further to understand the sintering effect, the specimens were annealed at 200, 400 and 600 oC for 2 hours and a detailed comparative study has been carried out. Such systematic and in-depth investigations guide one to understand the potential of modified ZnO on various applications such as thin-film solar cell applications.

description: Salt marshes are a valuable ecosystem with coastal protection potential, for example by absorbing hydrodynamic energy, increasing sedimentation and stabilizing the soil. This study investigated biomechanical properties of Spartina anglica to improve future models of wave-vegetation interaction. To fully understand the correlations between hydro- and biomechanics, the biomechanical vegetation properties from December 2021 to July 2022 are investigated with specimens collected from the field monthly. 551 specimens were used to determine the vegetation properties during storm surge season with high hydrodynamic forces. Additional geometrical properties were determined for 1265 specimens. Three-point bending tests measured the stiffness S (N/mm) and maximum forces Fmax (N). Different phenological states were observed over time and separated for analysis. These states provide a novel classification of growth periods for evaluating the coastal protection potential of Spartina anglica. Especially during storm season, most specimen were identified as broken shoots with a mean stiffness of 1.92N/mm (using 304 samples) compared to the bottom part of flowering shoots in December and January with a mean stiffness of 2.98N/mm (using 61 samples). The classification of plant properties recognizing phenological differences, based on plant state and seasonality, can be used to explain and reduce variability of biomechanical properties obtained during field campaigns. Additionally, this study shows that March to April is recommended for future investigations focusing on shoot properties during storm surge season, which is the important season for coastal engineers considering vegetation state.

description: Luminescent solar concentrator (LSC) devices have been in development for nearly fifty years, usually aiming at enhanced combinations of luminophores and photovoltaic solar cells. In this research, the focus is on the development of new geometric designs of LSC PV devices to improve the performance. The research has been executed by LSC device ray-tracing simulation using software LightTools for LSC PV configurations with a PMMA lightguide doped with Lumogen Red 305 dye. The set of LSC models evaluated have different sizes, different dye concentrations and silicon PV cells on the backside and along all four edges. The simulation results show that with changes in size from 10 to 1,000 mm and dye concentration from 5 to 100 PPM, a 5 mm thick LSC planar light guide can have a total optical efficiency in the range of 77% to 90%. Moreover, a curved LSC lightguide with a dye concentration of 100 PPM also provides a good performance with provided 81% optical efficiency at the backside.

description: Interferometric measurements of the radio emission of extensive air showers allow reconstructing cosmic-ray properties. A recent simulation study with an idealised detector promised measurements of the depth of the shower maximum $X_{max}$ with an accuracy better than 10 g cm$^{−2}$ [1]. In this contribution, we evaluate the potential of interferometric $X_{max}$ measurements of (simulated) inclined air showers with realistically dimensioned, sparse antenna arrays. We account for imperfect time synchronisation between individual antennas and study its inter-dependency with the antenna density in detail. We find a strong correlation between the antenna multiplicity (per event) and the maximum acceptable inaccuracy in the time synchronisation of individual antennas. From this result, prerequisites for the design of antenna arrays for the application of interferometric measurements can be concluded. For data recorded with a time synchronisation accurate to 1ns within the commonly used frequency band of 30MHz to 80MHz, an antenna multiplicity of $≳50$ is needed to achieve an $X_{max}$ reconstruction with an accuracy of 20 g cm$^{−2}$. This multiplicity is achieved measuring inclined air showers with zenith angles $θ≥77.5°$ with 1km spaced antenna arrays, while vertical air showers with zenith angles $θ≤40°$ require an antenna spacing below 100m. Furthermore, we find no improvement in $X_{max}$ resolution applying the interferometric reconstruction to measurements at higher frequencies, i.e., up to several hundred MHz.

description: In this work, we study an alternative path for Sb2Se3 preparation by thermal evaporation for low temperature substrate deposition. Thermal evaporation delivered, up to now, lower efficiency devices compared to close space sublimation based solar cells. One of the drawbacks of thermal evaporation for Sb2Se3 is the re-evaporation of Se on the substrate, for this reason we present an alternative route to adjust the stoichiometry of selenium deficient Sb2Se3 films by adding an excess of selenium (Se) for the deposition of 800 nm thin film by co-evaporation of Se and Sb2Se3. Thin films were deposited on Glass/FTO/SnO2/CdS substrate and their structural and electrical properties have been studied, together with the analysis of the finished devices.

description: Hydrogenation is a versatile tool in photovoltaic technology. To characterize several hydrogenated 2D In2Se3 nanomaterials and to reveal important hydrogenation features, we simulated from first principles, the structural, dynamical, electron and optical properties of the hydrogen induced systems by depositing H atoms on a quintuple layer (QL) -In2Se3 film. One-sided hydrogenation (when either the film’s top or bottom H is attached), substantially modifies the QL systems initial interatomic separation. Two-sided hydrogenation, by contrast, splits the pristine QL, forming two semiconducting InSeH and InSe2H nanofilms, both stable at 0K. Both the band structure and optical response of the split hydrogenated films significantly depend on the bonding type of the split film, namely InSeH or InSe2H. From a point view of technology, the two-sided H configuration allows for possible QL etching. The higher temperature MD results indicate a possible instability in the hydrogenated split structures analyzed here, which require further investigation.

description: Η διατήρηση της πολιτιστικής κληρονομιάς σε ένα νησί όπως η Σαντορίνη, με έντονο τουριστικό χαρακτήρα είναι ζητούμενο για να μην εξαλειφθεί μια μακροχρόνια παράδοση του δομημένου περιβάλλοντος. Το τοπίο δεν έχει αλλοιωθεί μόνο από τον τουρισμό αλλά και από τις σύγχρονες κατασκευαστικές πρακτικές κυρίως μετά το σεισμό του 1956. Η αιώνων παράδοση της κατασκευαστικής παραδοσιακής τέχνης με τα ιδιαίτερα υλικά (θηραϊκή γη και ηφαιστειακοί λίθοι) του νησιού ολοένα και φθίνει. Ένα από τα σημαντικότερα κτίρια στο νησί, ο Γουλάς στο Εμπορείο Θήρας κινδυνεύει να καταρρεύσει έπειτα από την εγκατάλειψή του σχεδόν 150 χρόνια. Ο αλλοτινός φεουδαρχικός πύργος αποτελεί μοναδικό παράδειγμα πύργου με ιδιαίτερα χαρακτηριστικά στην μορφολογία και την κατασκευή. Ανάλογα με τις ανάγκες κάθε περιόδου, το κτίσμα αναπροσαρμοζόταν για να αντιμετωπίσει προκλήσεις από τον ανθρώπινο παράγοντα ( κυρίως πειρατεία) και το φυσικό με πληθώρα σεισμικών διεγέρσεων. Έτσι, η διατριβή έχει θέμα τη διερεύνηση στατικής επάρκειας και απαιτούμενων επεμβάσεων για την αποκατάσταση του.
Από την πρώτη κατοίκηση του ανθρώπου στο νησί, η οποία χρονολογείται στην 5η χιλιετία π.Χ., οι κάτοικοι προσπάθησαν να προσαρμοστούν στην σεισμική δραστηριότητα λόγω της τοπολογίας του, πάνω στο ηφαιστειακό τόξο. Επομένως η μελέτη της δυναμικής απόκρισης της κατασκευής κρίνεται αναγκαία. Θα χρησιμοποιηθεί μία από τις κυριότερες μεθόδους ανάλυσης της τοιχοποιίας έναντι σεισμικών καταπονήσεων, αυτή της μεθόδου των πεπερασμένων στοιχείων. Ο πύργος θα προσομοιωθεί μέσα στο προγραμματιστικό περιβάλλον του MSC Marc Mentat.
Για την μοντελοποίηση απαιτείται ακριβή γεωμετρική αποτύπωση, η οποία τουλάχιστον εξωτερικά πραγματοποιείται με συνδυασμό μεθόδων κλασσικής τοπογραφίας και φωτογραμμετρίας με μη επανδρωμένο ιπτάμενο σύστημα (drone).
Για να προταθούν οι κατάλληλες επεμβάσεις, σε ένα μνημείο πρέπει να γίνει εκτενής βιβλιογραφική μελέτη για την ιστορία που φέρει. Το αποτέλεσμα της πρότασης, θα καθοριστεί από το συγκερασμό της αξιακής τεκμηρίωσης με τη δομοστατική του επάρκεια.

description: Conductive and transparent PEDOT:PSS-based composites with carbon nanotubes and silver nanoparticles have been prepared on a flat Si surface using the simplest technologies of layer-by-layer deposition, photochemical growth and spin-coating. From analysis of optical parameters it was obtained that these composite films in the spectral region of Si photosensitivity reveal high transmittance of light into Si substrate. Together with electrical DC conductivity investigations using a 4-point probe method, unambiguously it was observed that introduction of silver nanoparticles into the composite increases the plasma frequency of free carriers Ep of the film as a whole and film conductivity. Solar cells have been manufactured on a flat Si surface with these heterostructures. The introduction of metal nanoparticles (Ag) and SWCNT increases the efficiency of photoconversion in PEDOT:PSS/Si heterostructures by reducing the series resistance and increasing the fill factor of solar cells.

description: Forgings are produced in several process steps, the so-called forging sequence. The design of efficient forging sequences is a very complex and iterative development process. In order to automate this process and to reduce the development time, a method is presented here, which automatically generates multi-stage forging sequences for different forging geometries on the basis of the component geometry (STL file). The method was developed for closed die forging. The individual modules of this forging sequence design method (FSD method) as well as the functioning of the algorithm for the generation of the intermediate forms are presented. The method is applied to different forgings with different geometrical characteristics. The generated forging sequences are checked with FE simulations for the quality criteria form filling and freedom from folds. The simulation results show that the developed FSD method provides good approximate solutions for an initial design of forging sequences for closed die forging in a short time.

description: In the experiment the thermal copper oxide with sodium doping was elaborated. A simple bar coating technique was used for sodium deposition, while CuxO:Na layers were produced in IR belt furnace in only one temperature treatment. The morphology and composition of the manufactured coatings were analyzed. The presence of sodium atoms in the layer was confirmed by the EDS and SIMS techniques. The work function () of the layers was calculated from potential difference (CPD) measured by using Kelvin probe. The values dependence on the process temperature was found. Based on the obtained layers photovoltaic structure was prepared and its dark I-V was measured.
