Silicon Solar Cell Characterisation and Modelling

description: 32nd European Photovoltaic Solar Energy Conference and Exhibition; 519-522
description: Deposition of silicon nitride layers on top of silicon wafers using industrial plasma enhanced chemical vapor deposition systems is a major component in today’s manufacturing of silicon solar cells. Previous work has demonstrated non-uniformity in the optical properties within the bulk of dynamically deposited layers using such in-line systems. A gradient in the optical properties within the layer emphasizes the need for optical characterization as a function of the layer’s depth. This paper presents an advanced method to characterize dynamically deposited silicon nitride layers, where the modelling of the experimental ellipsometry spectra is performed by grading of the Tauc-Lorentz optical parameters along the normal of the layer. Significant improvements are demonstrated over the standard, more commonly used Tauc-Lorentz modelling procedure; mainly by revealing of the depth profiles of the layer’s optical properties.

description: We report on the new optical gating technique used for the direct photoconductive detection of short pulses of terahertz radiation with the resolution up to 250 femtoseconds. The femtosecond optical laser pulse time delayed with respect to the THz pulse generated a large concentration of the electron hole pairs in the AlGaAs/InGaAs High Electron Mobility Transistor (HEMT) drastically increasing the conductivity on the femtosecond scale and effectively shorting the source and drain. This optical gating quenched the response of the plasma waves launched by the THz pulse and allowed us to reproduce the waveform of the THz pulse by varying the time delay between the THz and quenching optical pulses. The results are in excellent agreement with the electro-optic effect measurements and with our hydrodynamic model that predicts the ultra-fast transistor plasmonic response at the time scale much shorter than the electron transit time, in full agreement with the measured data.

description: The parameters of the seasonal modulations (variations) in the intensity of muons and cosmogenic neutrons generated by them at a mean muon energy of 280 GeV have been determined in the LVD (Large Volume Detector) experiment. The modulations of muons and neutrons are caused by a temperature effect, the seasonal temperature and density variations of the upper atmospheric layers. The analysis performed here leads to the conclusion that the variations in the mean energy of the muon flux are the main source of underground cosmogenic neutron variations, because the energy of muons is more sensitive to the temperature effect than their intensity. The parameters of the seasonal modulations in the mean energy of muons and the flux of cosmogenic neutrons at the LVD depth have been determined from the data obtained over seven years of LVD operation.

description: The impact of the emitter diffusion and firing process on gettering and hydrogenation of multicrystalline
silicon is investigated with the aid of photoluminescence imaging and further image processing. Whilst the
use of high efficiency emitters is critical to improve surface passivation, multi-crystalline wafers using highefficiency
emitters suffered from a significantly reduced lifetime in the impurity-affected zone. For such diffusions, a
pre-gettering step was required to increase the lifetime in this region. A pre-gettering step was also beneficial for such
regions when using a screen print emitter. However the pre-gettering process was detrimental to the lifetime of other
regions of the material for both emitter diffusions. Heavily diffused wafers showed a strong response to hydrogen
passivation, particularly for non-gettered wafers. However, certain grains and the impurity-affected zone were
reduced in quality after firing, suggesting a poisoning of the silicon.

description: Recently, several striking advances have taken place regarding the discrete logarithm problem (DLP) in finite fields of small characteristic, despite progress having remained essentially static for nearly thirty years, with the best known algorithms being of subexponential complexity. In this expository article we describe the key insights and constructions which culminated in two independent quasi-polynomial algorithms. To put these developments into both a historical and a mathematical context, as well as to provide a comparison with the cases of so-called large and medium characteristic fields, we give an overview of the state-of-the-art algorithms for computing discrete logarithms in all finite fields. Our presentation aims to guide the reader through the algorithms and their complexity analyses ab initio.

description: Recently, many research institutes have reported that generation treatment of illumination and heating is a useful
method to transform boron–oxygen defects into a stable regenerated state for suppression of light induced degradation (LID) on
p-type PERC Cells. Based on considerations of the feasibility for mass production, the in-line regeneration tool is of much
competitiveness and superior properties, including less extra manpower for operation, no additional wafer handling and cost of
automations. However, the idea of compact design through the compromise between regeneration conditions and belt speed in
coordination with firing furnace is the major challenge for the development of in-line tool. In order to realize the concept, series
of experiment conditions, in terms of illumination intensity and duration, have been investigated in this work. The average
efficiency of regeneration treated cells with optimal condition shows as less as 0.1% efficiency loss relatively, compared to that of
non-regeneration treated cells. Furthermore, the LID results, which are conducted at one sun illumination condition for more than
60 hours, show that regeneration treated cells have significant improvement in degradation behavior with less than 2%
degradation while non-regeneration treated cells have as much as 3.6% efficiency degradation. Therefore, the in-line regeneration
treatment is a promising process technique to alleviate LID on p-type PERC cells.

The geometry of efficient arithmetic on elliptic curves
Creators: name: Kohel, David
Publisher: name: arXiv
Year: 2016
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: The arithmetic of elliptic curves, namely polynomial addition and scalar multiplication, can be described in terms of global sections of line bundles on $E\times E$ and $E$, respectively, with respect to a given projective embedding of $E$ in $\mathbb{P}^r$. By means of a study of the finite dimensional vector spaces of global sections, we reduce the problem of constructing and finding efficiently computable polynomial maps defining the addition morphism or isogenies to linear algebra. We demonstrate the effectiveness of the method by improving the best known complexity for doubling and tripling, by considering families of elliptic curves admiting a $2$-torsion or $3$-torsion point.

description: Aims: To investigate Low Frequency Electrical Muscle Stimulation (LF-EMS) in the advanced Chronic Heart Failure (CHF) population: 1) Characterise the physiological stimulus of LF-EMS, 2) Determine the feasibility of a Randomised Controlled Trial (RCT) in the CHF population, 3) Investigate effect of LF-EMS on vascular function.Methods and Results: Study one: Nine healthy males (mean age: 24.0 ±3.1 yrs) and 6 male patients with CHF (New York Heart Association class III- IV, mean age: 67.7 ± 14.1 yrs) undertook a 45-minute bout of LF-EMS (4Hz, continuous) of the legs. Oxygen uptake (VO2), was measured at 5-minute intervals along with multiple haemodynamic variables. VO2 increased in both groups (P<0.001), although patients with CHF demonstrated higher percentage of their maximal VO2 (5.8% [95%CI: 2.6, 7.9% :P<0.001]). Haemodynamic variables increased in both groups consistent with moderate exercise.Study two: Sixty participants with CHF were randomised to 8-weeks (5 x 60 minute per week) of LF-EMS (n=30) or ‘sham’ placebo (n=30). Recruitment, dropout and adherence were measured in addition to Six-Minute Walk Distance (6MWD) and quality of life (QoL). Sixty of 171 eligible participants (35.08%) were recruited, 12 (20%) patients withdrew. Forty-one patients (68.3%), adhered to the protocol (<70% of sessions). There were nosignificant differences between groups in 6MWD(P=0.13) and QoL (P=0.55). Study three: This study measured endothelial function using Flow Mediated Dilation (FMD) and maximal VO2 in a smaller cohort (LF-EMS n=20, ‘sham’ n=15). There was some evidence of enhanced FMD following LF-EMSiicompared to ‘sham’.Conclusions: Study one: LF-EMS can elicit a significantly greater cardiovascular response in patients with CHF compared to healthy individuals. Study two: People with CHF can be recruited to and tolerate LF-EMS studies; a larger RCT in this population is technically feasible.Study three: Patients with CHF using LF-EMS could gain prognostically significant improvements in endothelial function.

description: First Solar has launched mass production of high-efficiency crystalline silicon solar cells. The manufacturing sequence employs a new technology that eliminates recombination at the metal contacts. This “shielding” of the contacts allows a new degree of freedom for the metal grid design, i.e. the optimization is only a trade-off between shading and resistive losses. Contact recombination is so low that it doesn’t need to be factored in anymore. In combination with a fine line copper metallization process sequence, median efficiencies over 21% are achieved on a 100 MWp pilot line. 72-cell PV modules with standard soldering and interconnection technology have power bins (-0 to +5W) of 360 to 370 Wp.

description: We present a high-performance bifacial n-type solar cell with n+ polysilicon (polySi) back side
passivating contacts and fire-through screen-printed metallization, processed on 6" Cz wafers. The cells were
manufactured with low-cost industrial process steps yielding a best efficiency of 20.7%, and an average Voc of
674 mV. We analysed effects of variation of doping level, thickness, and oxide properties of the n-type polySi/SiOx
layers, as well as hydrogenation from a PECVD SiNx:H coating, which led to recombination current densities down
to ~2 fA/cm2 and ~4 fA/cm2 on planar and textured surface, respectively. The results are novel in four aspects: the
cells are bifacial, they are full 6" size while employing LPCVD for the polySi deposition, the polySi passivating
contact is metallized by fire-through screen printing paste, and hydrogenation is done by PECVD-deposited and fired
SiNx:H. Analysis shows that the wafer bulk lifetime in the cell is high and that the Voc of the cell is limited by the Jo
of the uniform diffused boron emitter and its contacts. Ways to improve the efficiency of the cell to > 22% are
indicated.

description: This study presents elemental abundances of the early A-type supergiant HD 80057 and the late A-type supergiant HD80404. High resolution and high signal-to-noise ratio spectra published by the UVES Paranal Observatory Project (Bagnulo et al., 2003) were analysed to compute their elemental abundances using ATLAS9 (Kurucz, 1993, 2005; Sbordone et al., 2004). In our analysis we assumed local thermodynamic equilibrium. The atmospheric parameters of HD 80057 used in this study are from Firnstein & Przybilla (2012), and that of HD80404 are derived from spectral energy distribution, ionization equilibria of Cr I/II and Fe I/II, and the fits to the wings of Balmer lines and Paschen lines as Teff = 7700 +/- 150 K and log g=1.60 +/- 0.15 (in cgs). The microturbulent velocities of HD 80057 and HD 80404 have been determined as 4.3 +/- 0.1 and 2.2 +/- 0.7 km s^-1 . The rotational velocities are 15 +/-1 and 7 +/- 2 km s^-1 and their macroturbulence velocities are 24 +/-2 and 2+/-1 km s^-1 . We have given the abundances of 27 ions of 20 elements for HD 80057 and 39 ions of 25 elements for HD80404. The abundances are close to solar values, except for some elements (Na, Sc, Ti, V, Ba, and Sr). We have found the metallicities [M/H] for HD 80057 and HD 80404 as -0.15 +/- 0.24 and -0.02 +/- 0.20 dex, respectively. The evolutionary status of these stars are discussed and their nitrogen-to-carbon (N/C) and nitrogen-to-oxygen (N/O) ratios show that they are in their blue supergiant phase before the red supergiant region.

description: Motivation: Next-generation sequencing tools have enabled producing of huge amount of genomic information at low cost. Unfortunately, presence of sequencing errors in such data affects quality of downstream analyzes. Accuracy of them can be improved by performing error correction. Because of huge amount of such data correction algorithms have to: be fast, memory-frugal, and provide high accuracy of error detection and elimination for variously-sized organisms. Results: We introduce a new algorithm for genomic data correction, capable of processing eucaryotic 300 Mbp-genome-size, high error-rated data using less than 4 GB of RAM in less than 40 minutes on 16-core CPU. The algorithm allows to correct sequencing data at better or comparable level than competitors. This was achieved by using very robust KMC~2 $k$-mer counter, new method of erroneous regions correction based on both $k$-mer counts and FASTQ quality indicators as well as careful optimization.

description: UV and visible multi-wavelength Raman spectroscopy was used to monitor the Si wafer-based p-n junction properties in photovoltaic (PV) devices. The crystallization quality and dopant profiles could be extracted by comparing characteristics of Raman spectrum such as intensity and peak shift with secondary ion mass spectroscopy (SIMS). For as-implanted wafers, broad amorphous Si peak around 475 cm-1 was observed and the shape changed with the degree of ion implantation damage. After rapid thermal anneal (RTA), pure Si peak at 520 cm-1 with small offsets for different implantation dose was observed, which means Raman spectroscopy could be a very promising and non-destructive measurement tool for monitoring quality of wafer-based ion-implanted silicon.
Magnetotransport in spin materials
Creators: name: Sharma, Elysia
Publisher: name: Imperial College London
Year: 2019

description: This thesis will explore magnetotransport in artificial spin ice (ASI) and RuO2. Small dimension ASI samples were fabricated in order to study systems undergoing thermal fluctuations in magnetisation. Optimisation of the fabrication process for small dimension ASI is outlined. Bar dimensions of 62nm x 18nm x 5.5nm were achieved. The magnetoresistance (MR) and Hall response of alternate geometry ASI systems were investigated in order to attempt to further understand previously observed asymmetric Hall signals in kagome ASI. The temperature dependence of the square, brickwork and Shakti arrays was investigated, in both the Hall and MR measurement configurations. Brickwork was found to exhibit the largest asymmetry, and all geometries showed a transition in behaviour below 50K. This is likely due to additional pinning of domain walls, resulting in a certain current path being favoured. The square lattice was measured with magnetic field parallel to applied current, as well as perpendicular. These measurements suggest that connected square ASI undergoes a different switching process to disconnected square ASI, which has not been previously reported (to the author's knowledge). Finally, magnetotransport measurements were performed on RuO2 thin films, in order to probe the temperature dependence of resistivity. The variation of resistivity with respect to applied field for a range of temperatures was also studied. The obtained Hall parameters were compared to values for IrO2, due to their similar structures. The temperature dependent Hall resistivity results show the same trends as IrO2, but with a smaller magnitude. The Hall measurements are consistent with a folded Fermi surface. A large single carrier "effective" mobility observed in the [100] and [110] orientations could be caused by possible hybridisation between the d and p bands. It could also be caused by the similar exotic band structure features that RuO2 shares with graphene.

description: We analyze a solenoidal motion in a vertically vibrated freely suspended thin smectic film. We demonstrate analytically that transverse oscillations of the film generate two-dimensional vortices in the plane of the film owing to hydrodynamic nonlinearity. An explicit expression for the vorticity of the in-plane film motion in terms of the film displacement is obtained. The air around the film is proven to play a crucial role, since it changes the dispersion relation of transverse oscillations and transmits viscous stresses to the film, modifying its bending motion. We propose possible experimental observations enabling to check our predictions.

description: We study the clustering of galaxies as a function of spectral type and redshift in the range $0.35 < z < 1.1$ using data from the Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) survey. The data cover 2.381 deg$^2$ in 7 fields, after applying a detailed angular selection mask, with accurate photometric redshifts [$σ_z < 0.014(1+z)$] down to $I_{AB} < 24$. From this catalog we draw five fixed number density, redshift-limited bins. We estimate the clustering evolution for two different spectral populations selected using the ALHAMBRA-based photometric templates: quiescent and star-forming galaxies. For each sample, we measure the real-space clustering using the projected correlation function. Our calculations are performed over the range $[0.03,10.0] h^{-1}$ Mpc, allowing us to find a steeper trend for $r_p \lesssim 0.2 h^{-1}$ Mpc, which is especially clear for star-forming galaxies. Our analysis also shows a clear early differentiation in the clustering properties of both populations: star-forming galaxies show weaker clustering with evolution in the correlation length over the analysed redshift range, while quiescent galaxies show stronger clustering already at high redshifts, and no appreciable evolution. We also perform the bias calculation where similar segregation is found, but now it is among the quiescent galaxies where a growing evolution with redshift is clearer. These findings clearly corroborate the well known colour-density relation, confirming that quiescent galaxies are mainly located in dark matter halos that are more massive than those typically populated by star-forming galaxies.

description: We discuss a physically motivated definition for a quantitative measure of the selectivity of electron and hole contacts. We define the selectivity S10 = log10(Vth /(c ×Jc)) to depend on the contact resistance c, the recombination current density Jc of the contact, and the thermal voltage Vth. A high selectivity relies on a highly asymmetric equilibrium carrier concentration of majority and minority carriers in the contact. The maximum efficiency max increases with the selectivity S10. This increase is linear until the efficiency starts to be limited by radiative recombination. We give analytic equations for calculating the maximum efficiency max(S10) of a crystalline Si cell that is ideal except for either one or two contacts. Achieving the maximum efficiency max requires optimized areal fractions fe,max and fh,max for the electron and the hole contacts, respectively . We give analytic equations for these contact fractions.

description: This paper addresses different aspects of "coupled" model descriptions in computational electromagnetics. This includes domain decomposition, multiscale problems, multiple or hybrid discrete field formulation and multi-physics problems. Theoretical issues of accuracy, stability and numerical efficiency of the resulting formulations are addressed along with advantages and disadvantages of the various approaches. Examples for multi-method, multi-domain, multi-formulation and multi-physics coupled formulations stem from numerical testing of electromagnetic compatibility in complex scenarios and numerical dosimetry of biological organisms in electromagnetic exposure situations and from simulations of large systems in electromagnetic power transmission.

description: We demonstrate a fully automated open-source magnetometer designed primarily for characterization of magnetic fields produced by coils, permanent magnets or by parasitic sources. It is based on an Arduino Mega microcontroller and a three-axis Hall sensor with a measurement range of +/-8 G per axis and the RMS of the field readout below 0.3 mG. For all practical purposes, the sensor displacement during data acquisition is virtually unlimited, which can be particularly useful for characterizing large or extended coils like Helmholtz cages or Zeeman slowers. All components needed for the construction are cheap and widely available off-the-shelf elements or are 3D-printed. The operation of the magnetometer is controlled via a graphical user interface (GUI), which manages all essential functionalities, like data acquisition and plotting. The GUI also incorporates additional features, like data averaging, calibration of the displacement of the Hall sensor or real-time readout of the magnetic field, useful for monitoring magnetic field changes. We have used a pair of rectangular coils constructed for a potassium--cesium 2D magneto-optical trap to benchmark the performance of the magnetometer. We have obtained good agreement with both simulations and measurements acquired with a commercial gaussmeter.

description: Intermetallic compounds (IMC) in solder bonds are commonly considered critical for the reliability of interconnections. The microstructure and thermal aging characteristics of solder bonds of crystalline silicon solar cells are investigated, whereby two solders, Sn60Pb40 and a lead-free, low melting point alternative Sn41Bi57Ag2 are considered. Solder bonds of front side busbars are formed with a semi-automatic tool and cross sections are prepared, which are characterized with confocal laser microscopy, scanning electron microscopy and energy dispersive x-ray spectroscopy (EDX). The kinetic of IMC growth is modeled with a diffusion model, and the parameters are obtained with systematic thermal aging studies and the Arrhenius relationship. The model is capable of processing non-isothermal temperature profiles and is used to simulate IMC growth during PV module reliability tests like thermal cycling 600 (TC) and damp heat for 3000 h. Furthermore, the thicknesses of the IMCs are estimated for a PV module in an outdoor location. It is found that solder joints undergo strong ripening processes during thermal aging. In particular, Sn41Bi57Ag2 solder joints show faster IMC growth, grain coarsening and Sn-penetration into the busbar than Sn60Pb40 bonds. Sn-penetration is observed already in the as-soldered condition and EDX confirms the existence of significant amounts of diffused Sn around cavities in the busbar. Large portions of the busbar are consumed by the Ag3Sn IMC after 155 h at 130 °C and further aging of the Sn41Bi57Ag2 joint leads to Bi segregation and, in some cases, complete depletion of Sn from the solder matrix. The simulation of IMC growth shows a final IMC thickness after TC 600 of 1.2 μm and 1.5 μm; furthermore, a thickness after 3000 h at 85°C of 2.6 μm and 3.7 μm respectively for Ag3Sn in Sn60Pb40 and Ag3Sn in Sn41Bi57Ag2 bonds. The prognosis of IMC growth in a PV module in the outdoor location estimates an Ag3Sn thickness of 1.2 μm and 1.3 μm for Sn60Pb40 and Sn41Bi57Ag2 respectively due to the rare occurrence of temperatures above 60 °C.

The role of TAM receptors in immuneparesis in tissue compartments in liver failure syndromes
Creators: name: Singanayagam, Arjuna
Publisher: name: Imperial College London
Year: 2019

description: Background: Decompensated liver cirrhosis and acute-on-chronic liver failure (ACLF) – liver failure syndromes - are associated with increased incidence of bacterial infection, often spontaneous bacterial peritonitis (SBP), and a subsequent higher mortality. Within a model of pathological bacterial translocation, immuneparesis increases the susceptibility to infection. TAM receptor MerTK, expressed on monocytes and macrophages, mediates apoptotic cell clearance and attenuates responses to microbial challenge. Whilst MerTK+ circulating monocytes are expanded in ACLF, its role in conjunction with other TAM receptors, Axl and Tyro3, is not known in tissue compartments, such as the peritoneum and liver. In this thesis, I describe the tissue compartmental macrophage phenotype and function in cirrhosis and ACLF, focusing on TAM receptors, and the relationship to microenvironmental mediators. Methods: Combinations of flow cytometry, gene expression analyses and live cell imaging determined the phenotypic, functional and transcriptomic profile of MerTK+ monocytes/macrophages in cirrhosis and ACLF, in the circulation, peritoneum and liver. The composition of the ascitic microenviroment was determined by enzyme-linked immunosorbent assay (ELISA) and 1H-NMR metabonomics. Results: Circulating monocyte MerTK expression in ACLF was markedly elevated whilst Axl was low-level and Tyro3 variable. The peritoneum in cirrhosis was immunotolerant, characterized by MerTK[high] Axl[low] macrophages primed for apoptotic cell clearance, with impaired antimicrobial cytokine and oxidative burst responses but preserved phagocytosis. In ACLF, ascites contained pro-inflammatory cytokines, metabolites from anaerobic and lipid metabolism and increased apoptotic/necrotic cell death markers in conjunction with higher TAM receptor expression. Hepatic macrophages displayed intermediate MerTK expression. Conclusions: The work presented in this thesis has determined the TAM receptor expression across tissue compartments, the ascitic microenvironment in cirrhosis and ACLF and identified MerTK as a promising immunotherapeutic target to restore innate immune function in the evolution of ACLF.

On turbulence driven by axial precession and tidal evolution of the spin-orbit angle of close-in giant planets

description: The spin axis of a rotationally deformed planet is forced to precess about its orbital angular momentum vector, due to the tidal gravity of its host star, if these directions are misaligned. This induces internal fluid motions inside the planet that are subject to a hydrodynamic instability. We study the turbulent damping of precessional fluid motions, as a result of this instability, in the simplest local computational model of a giant planet (or star), with and without a weak internal magnetic field. Our aim is to determine the outcome of this instability, and its importance in driving tidal evolution of the spin-orbit angle in precessing planets (and stars). We find that this instability produces turbulent dissipation that is sufficiently strong that it could drive significant tidal evolution of the spin-orbit angle for hot Jupiters with orbital periods shorter than about 10-18 days. If this mechanism acts in isolation, this evolution would be towards alignment or anti-alignment, depending on the initial angle, but the ultimate evolution (if other tidal mechanisms also contribute) is expected to be towards alignment. The turbulent dissipation is proportional to the cube of the precession frequency, so it leads to much slower damping of stellar spin-orbit angles, implying that this instability is unlikely to drive evolution of the spin-orbit angle in stars (either in planetary or close binary systems). We also find that the instability-driven flow can act as a system-scale dynamo, which may play a role in producing magnetic fields in short-period planets.

description: 32nd European Photovoltaic Solar Energy Conference and Exhibition; 452-455
description: In this paper, we study the passivation quality of p-type poly-Si / c-Si junctions annealed at different temperatures. We evaluate wet-chemically grown (ozonized in DI-H2O) and thermally-grown interfacial oxides and compare boron ion implantation into intrinsic poly-Si with different doses to in situ p+ doping during the LPCVD Si deposition process. The experimental results show that decreasing the doping concentration of the p+ poly-Si layer and increasing the annealing temperature improve the passivation quality of the p+ poly-Si / c-Si junctions. Additionally, we explore the passivation quality of p-type poly-Si / c-Si junctions on different surface morphologies and orientations, i.e. on planar (100) and (111) as well as alkaline textured Si surfaces. Textured surfaces show a strongly increased J0e, possibly due to a worse p-type poly-Si passivation on (111) surfaces. The emitter saturation current density J0e of 8 fA/cm² achieved on planar (100) surfaces is the lowest value reported for p+ poly-Si / c-Si junctions with wet-chemically grown oxides so far.

description: On the basis of the Galactic O-Star Spectroscopic Survey (GOSSS), a detailed systematic investigation of the O Vz stars is presented. The currently used spectral classification criteria are rediscussed, and the Vz phenomenon is recalibrated through the addition of a quantitative criterion based on the equivalent widths of the He I 4471, He II 4542, and He II 4686 spectral lines. The GOSSS O Vz and O V populations resulting from the newly adopted spectral classification criteria are comparatively analyzed. The locations of the O Vz stars are probed, showing a concentration of the most extreme cases toward the youngest star forming regions. The occurrence of the Vz spectral peculiarity in a solar-metallicity environment, as predicted by the fastwind code, is also investigated, confirming the importance of taking into account several processes for the correct interpretation of the phenomenon.

description: We investigated the vortex phase diagram of needle shaped high quality NiBi3 single crystals by transport measurements. The current is applied along the crystalline b-axis of this intermetallic quasi-1D BCS superconductor. The single crystals show a Ginzburg-Levanchuk (Gi) parameter few orders of magnitude larger than other low Tc BCS superconductors. Vortex phase diagram, critical currents and pinning forces have been extracted from the experimental data. The main findings are: 1) Enhancement of the vortex liquid phase in comparison with low Tc superconductors, 2) reentrance of the liquid phase at low fields and 3) deviation of the pinning force vs field from the usual pinning mechanisms. The interplay between weak pinning, due to quenched disorder, and the quasi-1D character of the material could be a hint to explain the lack of a single pinning mechanism.
