Silicon Feedstock, Crystallisation and Wafering

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 984-989
description: Mono-cast silicon recently became available in volumes relevant for industrial scale production of
solar-cells. One important question in this field is how these wafers can be classified into quality groups and how
this can be specified and measured. This paper discusses solar-cell efficiency distributions of mono-cast wafers
which were obtained in first tests using an industrial cell process using acidic and alkaline texturing. High
efficiencies up to the level of Czochralski mono wafers could be obtained for single wafers. The (optical)
classification based on the percentage of <100> oriented area is shown to be insufficient to predict and guarantee
a good separation of high quality and low quality wafers, because also <100> oriented grains can contain high
defect densities. An analysis of the defects structures in the wafers and cells using photoluminescence,
electroluminescence and defect etching reveals that the amount of defects generated at boundaries of seed crystals
depends strongly on the alignment of the seeds and that the structural defects can be separated in the same defect
classes as observed for standard multicrystalline silicon wafers. For a good sorting and specification of mono-cast
wafers in the future, the further development of methods to measure and quantify crystal defect structures will
therefore be essential.

description: We investigate potential correlations between radio source counts (after background corrections) of 22 Galactic globular clusters (GCs) from the MAVERIC survey, and stellar encounter rates ($Γ$) and masses ($M$) of the GCs. Applying a radio luminosity limit of $L_\mathrm{lim}=5.0\times 10^{27}~\mathrm{erg~s^{-1}}$, we take a census of radio sources in the core and those within the half-light radius. By following a maximum likelihood method and adopting a simplified linear model, we find an unambiguous dependence of core radio source counts on $Γ$ and/or $M$ at 90% confidence, but no clear dependence of source counts within the half-light radius on either $Γ$ or $M$. Five of the identified radio sources in cores above our adopted limit are millisecond pulsars or neutron star X-ray binaries (XRBs), the dependence of which on $Γ$ is well-known, but another is a published black hole (BH) XRB candidate, and ten others are not identified. Accounting for the verified cluster members increases the significance of correlation with $M$ and/or $Γ$ (to 99% confidence), for fits to core and half-light region source counts, while excluding a dependence on $Γ$ alone at 90% (core) and 68% (half-light) confidence. This is consistent with published dynamical simulations of GC BH interactions that argue $Γ$ will be a poor predictor of the distribution of accreting BHs in GCs. Future multiwavelength follow-up to verify cluster membership will enable stronger constraints on the dependence of radio source classes on cluster properties, promising a new view on the dynamics of BHs in GCs.

description: Chronic obstructive pulmonary disease (COPD) is estimated to become the third cause of mortality by 2030 (WHO., 2020). In PulmonDB (Villaseñor-Altamirano et al., 2020), a transcriptome database for pulmonary diseases, we found several genes with discordant gene expression pattern in COPD patients across studies, among these genes we found Hedgehog interacting protein(HHIP), a gene previously associated with COPD (Obeidat et al., 2015). In this project, we aim to assess if HHIP expression could be affected by regulatory variants. In order to do so, we retrieved genetic variants in the vicinity of HHIP loci reported in the literature. We found eQTLs with opposite effects on HHIP gene expression, 3 associated with overexpression (Obeidat et al., 2015; Wang et al and 2013 Fawcett et al., 2019) and 7 to downregulation(Zhou et al., 2013, Tam et al., 2019, Bartholo et al., 2019, Woo & Sang., 2015 & Lao et al., 2015).To assess if these genetic variants could be affecting transcription factor binding interactions we used RSAT Variation-tools with non-redundant Jaspar motifs, finding potential binding site modifications that could explain the variation of gene expression across experiments.

description: We present the results of a one year monitoring campaign of the Seyfert 1.9 galaxy NGC 2992 with RXTE. Historically, the source has been shown to vary dramatically in 2-10 keV flux over timescales of years and was thought to be slowly transitioning between periods of quiescence and active accretion. Our results show that in one year the source continuum flux covered almost the entire historical range, making it unlikely that the low-luminosity states correspond to the accretion mechanism switching off. During flaring episodes we found that a highly redshifted Fe K line appears, implying that the violent activity is occurring in the inner accretion disk, within ~100 gravitational radii of the central black hole. We also found that the spectral index of the X-ray continuum remained approximately constant during the large amplitude variability. These observations make NGC 2992 well-suited for future multi-waveband monitoring, as a test-bed for constraining accretion models.

description: The present study relates to photovoltaic cells comprising transparent conductive oxide (TCO) films of hydrogenated tungsten-doped In2O3 (IWOH) which were deposited by an ion-plating (IP) technique. Hydrogenated amorphous silicon (a-Si:H)/crystalline silicon (c-Si) heterojunction (SHJ) solar cells comprising IWOH films as TCO layers are fabricated. It was confirmed that the conversion efficiency was improved by IWOH films having a single (222) XRD peak at 30.6±0.1 2/degree compatibly attaining high fill factor and high Jsc. The conversion efficiency of 22.3% was achieved on average for four 4 cm2 SHJ cells comprising IWOH films having lager hydrogen number density than 5.0 × 1020 atoms cm-3.

description: The solar dipole moment at cycle minimum is considered to be the most successful precursor for the amplitude of the subsequent cycle. Numerical simulations of the surface flux transport (SFT) model are widely used to effectively predict the dipole moment at cycle minimum. Recently an algebraic method has been proposed to quickly predict the contribution of an active region (AR) to the axial dipole moment at cycle minimum instead of SFT simulations. However, the method assumes a bipolar magnetic region (BMR) configuration of ARs. Actually most ARs are asymmetric in configuration of opposite polarities, or have more complex configurations. Such ARs evolve significantly differently from that of BMR approximations. We propose a generalized algebraic method to describe the axial dipole contribution of an AR with an arbitrary configuration, and evaluate its effectiveness compared to the BMR-based method. We employ mathematical deductions to obtain the generalized method. We compare the results of the generalized method with SFT simulations of observed ARs, artificially created BMRs, and ARs with more complex configurations. We also compare the results with that from the BMR-based method. The generalized method is equivalent to the SFT model, and precisely predicts the ARs' contributions to the dipole moment. The method has a much higher computational efficiency than SFT simulations. Although the BMR-based method has similar computational efficiency as the generalized method, it is only accurate for symmetric bipolar ARs. The BMR-based method systematically overestimates the dipole contributions of asymmetric bipolar ARs, and randomly miscalculate the contributions of more complex ARs. The generalized method provides a quick and precise quantification of an AR's contribution to the solar cycle evolution, which paves the way for the application into the physics-based solar cycle prediction.

description: There are two common settings in a quantum-state discrimination problem. One is minimum-error discrimination where a wrong guess (error) is allowed and the discrimination success probability is maximized. The other is unambiguous discrimination where errors are not allowed but the inconclusive result "I don't know" is possible. We investigate discrimination problem with a finite margin imposed on the error probability. The two common settings correspond to the error margins 1 and 0. For arbitrary error margin, we determine the optimal discrimination probability for two pure states with equal occurrence probabilities. We also consider the case where the states to be discriminated are multipartite, and show that the optimal discrimination probability can be achieved by local operations and classical communication.

description: Many researchers point out that wafer quality affects performance of silicon heterojunction (SHJ) solar cells. Especially, in case of n-type wafers, resistivity varies greatly by uneven distribution of dopant concentration derived from phosphorus segregation even in one ingot. In addition, thermal donors (TDs) which mainly exist in top regions of ingots are generated in Si crystals during the Czochralski (CZ) growth process. Resistivity of the top
regions was dropped by the presence of many TDs, although the essential resistivity can be obtained by a donor killer
annealing (DKA). Besides passivation ability by a-Si:H films was remarkable and the longest lifetime of 5.7 ms was
obtained. As a result of evaluation of wafers made from several regions in an ingot, the highest performance of the
wafers located in 200 ~ 300 mm below the top of ingots was confirmed. Certified conversion efficiency of 21.11%
and open circuit voltage (Voc) of 733.3mV were achieved by fabricating 6-inch SHJ solar cells using these wafers
from such positions in an ingot. Furthermore, output power of 302.2W and module efficiency of 18.5% were
achieved in a prototype module of a standard residential size comprising these 60 cells.

description: We study the changes in the conformations of brushes upon the addition of crosslinks between the chains using the bond fluctuation model. The Flory-Rehner model applied to uni-axially swollen networks predicts a collapse for large degrees of crosslinking $q$ proportional to $q^{-1/3}$ in disagreement with our simulation data. We show that the height reduction of the brushes is driven by monomer fluctuations in direction perpendicular to the grafting plane and not due to network elasticity. We observe that the impact of crosslinking is different for reactions between monomers of the same or on different chains. If the length reduction of the effective chain length due to both types of reactions is accounted for in a function $β(q)$, the height of the brush can be derived from a Flory approach for the equilibrium brush height leading to $H(q)\approx H_{b}β(q)^{1/3}$, whereby $H_{b}$ denotes the height of the non-crosslinked brush.

description: We use high-signal-to-noise ($\sim$150-450), high resolution ($R{\sim}45,000$) Keck HIRES spectroscopy of 13 candidate post T Tauri stars to derive basic physical parameters, lithium abundances and radial velocities. We place our stars in the M$_v$-T$_{eff}$ plane for use in determining approximate ages from pre-main sequence isochrones, and confirm these using three relative age indicators in our analysis: Li abundances, chromospheric emission and the kinematic {\it U-V} plane. Using the three age criteria we identify 5 stars (HIP 54529, HIP 62758, HIP 63322, HIP 74045, and HIP 104864) as probable post T Tauri stars with ages between 10 and 100 Myr. We confirm HIP 54529 as an SB2 and HIP 63322 as an SB1 star. We also examine irregular photometric variability of PTTs using the {\it HIPPARCOS} photometry annex. Two of our PTT stars exhibit near-IR excesses compared to Kurucz model flux; while recent work suggests classical T Tauri stars evince similar {\it JHK} excesses presumably indicative of non-photospheric (disk) emission, our results may be illusory artifacts of the chosen {\it I}-band normalization. Near-IR excesses we see in a literature-based sample of PTTs appear to be artifacts of previous spectral type-based $T_{\rm eff}$ values. Indeed, comparison of the homology of their observed and model photospheric SED's suggests that photometric temperatures are more reliable than temperatures based on spectral standards for the cooler temperature ranges of the stars in this sample. We conclude that our age oriented analysis is a robust means to select samples of nearby, young, isolated post T Tauri stars that otherwise masquerade as normal field stars.

description: Different wet-chemical treatments of crystalline Si wafers for the preparation of heterojunction solar cells are optimized with respect to low reflection losses, low recombination losses and long carrier lifetimes. It is demonstrated that a joint optimization of both saw damage etch and texture etch is necessary to control the pyramid
morphology. Best results are reached for intermediate saw damage removals and texture etch times. Wet-chemical
preconditioning by oxidation in hot water and by using ozone at ambient temperatures is found to yield high-quality surfaces with low defect densities. These methods are considered as low-cost alternatives to conventional approaches. The surface photovoltage (SPV) technique is established as efficient tool for technology optimization and allows a fast and reliable interface characterization and the quantitative determination of interface defect densities.

description: The highest solar cell efficiencies both for c-Si and mc-Si were reached using template based texturing
processes. Especially for mc-Si the benefit of a defined texture, the so called honeycomb texture, was demonstrated
impressively. However, up until now, no industrially feasible process has been available to pattern the necessary
etching masks with the sufficient resolution. Roller-Nanoimprint Lithography (Roller-NIL) has the potential to
overcome these limitations and to allow high quality pattern transfers, even in the sub-micron regime, in continuous
in-line processes. Therefore, this etch-mask patterning technique is a suitable solution to bring such elaborate features
like the honeycomb texture to an industrial realization. Beyond that, this fast printing-like technology opens up new
possibilities to introduce promising concepts like photonic structures into solar cells.

description: In this paper, it is shown how different passivation layers are created for emitters with different sheet resistance. However, the main point is contacting of emitters with different sheet resistance.
Emitters were made by boron diffusion from a liquid source BBr3. Sheet resistance of emitters ranged from 30 ohm/sq to 100 ohm/sq. To remove BRL (Boron Rich Layer) an oxidation step was used during diffusion. ECV techniques were applied for evaluation of boron concentration profile.
Passivation layers were created using three methods on all types of emitters. The first method is based on no removal of boron oxide after boron diffusion and deposition of PECV nitride SiNx. The second method is based on the removal of boron oxide and deposition of PECVD nitride SiNx. The last method is based on the removal of boron oxide and deposition of PECVD oxide SiOx + PECVD nitride SiNx. Passivation properties were investigated before and after firing of metallization by the MWPCD method.
Different metallization pastes are used for described structures. Emitters contacting is observed depending on the conditions of IR firing and screen printing of different pastes.

description: A novel outdoor monitoring system for PV modules has been developed, where custom designed DCDC
converters enable continuous maximum power point tracking with simultaneous current, voltage and temperature
monitoring of each PV module in the system. Besides MPP each PV module can be set in any operational regime
including short- circuit or open-circuit. Three CIGS and three multi-crystalline silicon PV modules have been monitored
for six months from April this year in all three regimes. Their module-to-ambient temperature difference is linearly
dependent of in–plane irradiance showing different in different operation regimes. The slope variation agrees well to
linear energy balance model, which predicts highest slope in OC conditions and lowest in MPP, where maximal power is
extracted from the PV modules. Slope in SC conditions is close to the slope in OC conditions, where the small difference
can be attributed to the power that dissipates on the series resistance and external resistance due to non-ideal short circuit
conditions.

description: We present spectroscopic and photometric observations of the eclipsing binary V32 located in the central field of the globular cluster NGC 6397. The variable is a single-line spectroscopic binary with an orbital period of 9.8783d and a large eccentricity of e=0.32. Its systemic velocity (gamma=20.7 km/s) and metallicity ([Fe/H] -1.9) are both consistent with cluster membership. The primary component of the binary is located at the top of the main-sequence turn-off on the cluster color-magnitude diagram. Only a shallow primary eclipse is observed in the light curve. Based on stellar models for an age of 12Gyr and the mass-function derived from the radial velocity curve, we estimate the masses to be M_p=0.79 Msun and M_s=0.23 Msun. The light curve of V32 can be reproduced by adopting R_p=1.569 Rsun and R_s=0.236 Rsun for the radii and i=85.44 deg for the system inclination. The system geometry precludes observations of the secondary eclipse. The large eccentricity of the orbit is puzzling given that for metal poor, halo binaries the transition from circular to eccentric orbit occurs at an orbital period of about 20 days. We suppose that the orbit of V32 was modified relatively recently by dynamical interaction with other cluster star(s).An alternative explanation of the observed eccentricity calls for the presence of a third body in the system.

description: Scaling aspects of Gaussian topological phase-transitions in quantum spin chains are investigated using the prototypical one-dimensional spin-1 XXZ Heisenberg model with uniaxial single-ion anisotropy $D$. This model presents a critical line separating the gaped Haldane and large-$D$ phases, with the relevant energy gap closing at the transition point. We show that a proper tangential finite-size scaling analysis is able to accurately locate the Gaussian critical line and to probe the continuously varying set of correlation length critical exponents. The specific features of the tangential scaling are highlighted in contrast with the standard scaling holding in the Ising-like transition between the gapless AF-Néel and gaped Haldane phases. Our results are compared with field-theoretic predictions and available high-accuracy data for specific points along the Gaussian line.

The concept of sacred war in Ancient Greece
Creators: name: Skoczylas, Frances Anne
Publisher: name: University of British Columbia
Year: 2010

description: This thesis will trace the origin and development of the term "Sacred War" in the corpus of extant Greek literature. This term has been commonly applied by modern scholars to four wars which took place in ancient Greece between the sixth and fourth centuries B. C. The modern use of "the attribute "Sacred War" to refer to these four wars in particular raises two questions. First, did the ancient historians give all four of these wars the title "Sacred War?" And second, what justified the use of this title only for certain conflicts? In order to resolve the first of these questions, it is necessary to examine in what terms the ancient historians referred to these wars. As a result of this examination, it is clear that only two of the modern series of "Sacred Wars" (the so-called Second and Third Sacred Wars) were actually given this title in antiquity. The other two wars (the so-called Second and Third Sacred Wars), although they were evidently associated by the ancients with the "Sacred Wars," were not given this attribution. Consequently, the habit of grouping all four wars together as "Sacred Wars" is modern. Nevertheless, the fact that the ancients did see some connection between these wars does justify this modern classification to some degree. Once this conclusion had been reached, it became possible to proceed to the second of the problems presented in this thesis, namely the justification for the application of the title "Sacred War" to two specific conflicts. In order to achieve this aim, those conflicts labelled "Sacred Wars" by the ancient historians were compared to two categories of test cases: the other two conflicts classified as "Sacred Wars" by modern scholars and conflicts which share elements in common with "Sacred Wars" but which are not given this attribution by ancient or modern authorities. In the course of this comparison, I discovered that little differentiated the so-called "Sacred Wars" from the non-"Sacred Wars" and that all of these latter conflicts appear equally worthy of the title as those which were in fact given this attribution. The deciding factor in the classification of a certain conflict as a "Sacred War," as a result, lies not in the specific elements making up its constitution but rather in the political circumstances surrounding it. The two conflicts labelled by the ancients as "Sacred Wars" were given this title by contemporary powers in order to justify military interference in the political affairs of other states which might otherwise have been considered unnecessary. Thus, the term "Sacred War" arose originally as the result of an effective propaganda campaign.

description: We examine the dependence of silicon melt threshold, melt duration and sheet resistance during laser
doping of silicon. For this investigation we use double-pulse experiments and time resolved reflectivity
measurements of nanosecond laser pulse irradiation. The melt thresholds of the double-pulses increase with the
extension of the delay period between subsequent laser pulses. Longer melt durations and lower sheet resistances are
achieved for shorter delays between the laser pulses. In combination with an analytical calculation of surface
temperature during the laser induced melting and recrystallization process, the experimental results allow conclusions
on the interrelationship between silicon surface temperatures, melt duration and dopant diffusion. We conclude that
performing the laser doping process with high-repetition-rate lasers reduce sheet resistances more efficiently.

description: We study the effects of polymer thickness on the performance of silicon-organic hybrid solar cells
based on single crystal Si wafer absorber and a transparent polymer, poly (3,4-ethylene-dioxythiophene):
polystyrenesulfonate (PEDOT: PSS). At a PEDOT thickness of ~78nmthe planar Si/PEDOT hybrid cells
demonstrate the highest short circuit current density (Jsc) of 27mA/cm2 owing to the low reflection in the visible
light region (especially from 450 nm to 650 nm). It is found that increasing or decreasing the polymer thickness
reduces the Jsc as well as the power conversion efficiency (PCE) of the cells. The open circuit voltage (Voc) is
comparable among the cells with different PEDOT thicknesses, and varies from 0.60 ~ 0.61 V. There is a decrease in
the fill factor (FF) for the cells with a thicker PEDOT layer.

description: Cities of the 21st century are impacted by uniquely modern phenomena such as sea-level rise, urban flooding, and decentralization. As environmental impacts and urban dynamics change, we are forced to view urban spaces differently than we have in the past. Landscape Urbanism developed in the early 1990s as a response to this need, turning to the landscape as a foundation for viewing, constructing, and rehabilitating urban spaces. Although Landscape Urbanism theory does provide a platform to determine what sites are ideal for development and how to design with environmental and ecological systems on a site, the abstract nature of the literature of Landscape Urbanism creates challenges in practice. This thesis combines investigation into Landscape Urbanism theory with research on the methodologies of Sustainable Urbanism, Smart Growth, and Ecological Urbanism to create a framework for the application of Landscape Urbanism to site design. This framework is then tested in the conceptual redevelopment of a former industrial site in Baltimore, Maryland.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 214-217
description: At the PV Lab of the Ioffe Institute, a multifunctional flash solar simulator/tester has been developed. It may be used as the cost-effective means applied at characterization of the 1-sun and concentrator cells, as well as large area flat and concentrator modules. At the 1 sun irradiation level and light divergence corresponding to that from the Sun disc, light from Xenon lamps passes through an aperture hole 20 mm in diameter and a large-area Fresnel lens with 2000 mm focal distance to form a collimated flux the 0.5x 0.5 m2 aperture area. Easy reconfiguration of the simulator structure allows characterizing individual cells, or large-area flat modules, under noncollimated
light flux. In this case, light flux is much more extended in area, so that a flat solar array may be placed far enough for realization of the 1-sun illumination conditions. In turn, the concentrator solar cells may be characterized at their placing much closer to flash lamps. At a -like light pulse shape, it is possible to record an I-V curve in three quadrants during 1 millisecond. The technical parameters and results on the I-V measurements by means of the
developed multifunctional solar simulator/tester are presented.

description: In the mid-Atlantic United States, legume cover crop adoption is limited by the shortened establishment window after double-crop soybean (Glycine max (L.) Merr.) harvest. Interseeding legume cover crops into wide-row (76 cm) double-crop soybean presents an opportunity to supplement inorganic nitrogen (N) fertilizer in the subsequent corn (Zea mays L.) crop. We conducted field trials in Maryland and Delaware in which mixtures of cereal rye (Secale cereale L.) + hairy vetch (Vicia villosa Roth), crimson clover (Trifolium incarnatum L.), red clover (Trifolium pratense L.), or winter pea (Pisum sativum var. arvense (L.) Poir) were interseeded into double-crop soybean. We then examined the N contributions of the cover crop mixtures in combination with sidedress applications of inorganic N fertilizer on corn yields in Maryland in 2018 and 2019. This research demonstrated that interseeding cover crops into double-crop soybean is a potential strategy for increasing regional adoption of legume cover crops.

description: Laser scribing is a suitable structuring method for thin-film organic solar modules on PET-foil aiming the
roll-to-roll processing. Results on laser scribing of a transparent electrode: highly conductive PEDOT:PSS, as an
alternative to the conventionally used ITO are presented. The most important parameters in thin film laser processing are
the wavelength, pulse duration, pulse energy, and spot-to-spot overlap. Effects and dependencies on material ablation by
processing with laser radiation at several wavelengths (e.g. 355 nm, 532 nm, and 1064 nm) and pulse durations in the
pico-, subnano-, and nanosecond range were studied. Organic test modules were produced using laser structuring.
Optimal processing parameters and laser sources are discussed considering a feasible and rapid implementation into a
roll-to-roll mass production system.
Kinematics of Spiral Arm Streaming in M51

description: We use CO and H alpha velocity fields to study the gas kinematics in the spiral arms and interarms of M51 (NGC 5194), and fit the 2D velocity field to estimate the radial and tangential velocity components as a function of spiral phase (arm distance). We find large radial and tangential streaming velocities, which are qualitatively consistent with the predictions of density wave theory and support the existence of shocks. The streaming motions are complex, varying significantly across the galaxy as well as along and between arms. Aberrations in the velocity field indicate that the disk is not coplanar, perhaps as far in as 20\arcsec\ (800 pc) from the center. Velocity profile fits from CO and H alpha are typically similar, suggesting that most of the H alpha emission originates from regions of recent star formation. We also explore vortensity and mass conservation conditions. Vortensity conservation, which does not require a steady state, is empirically verified. The velocity and density profiles show large and varying mass fluxes, which are inconsistent with a steady flow for a single dominant global spiral mode. We thus conclude that the spiral arms cannot be in a quasi-steady state in any rotating frame, and/or that out of plane motions may be significant.

description: A system for the continuous monitoring of scour has been designed, constructed and implemented.  The system detects the level of scour by attaching flow to a buried post at known depths, and detecting when individual sensors become unearthed.  Two bio-inspired flow sensors were designed and constructed for use on the post.  The first, resembling a seal whisker, utilized the magnetostrictive materials Alfenol and Galfenol and was optimized for >0.15m/s flow.  The second, resembling seaweed, used a conventional permanent magnet and was optimized for <0.15m/s flow.  A small, low powered data acquisition system was designed and constructed to monitor and record the data from the sensors.  A total of four scour posts were installed at two different sites; two vertically to monitor conventional scour and two horizontally to monitor lateral riverbed migration.  Data from the posts was analyzed and presented and lessons learned were documented.
