description: The three-phase low-voltage electrical distribution grids are characterized with big number of singlephase
consumers, which leads to asymmetry in the working conditions of the grid. Connecting single-phase distributed
generation (DG) to three-phase low-voltage grid causes additional asymmetry. This paper presents the developed
methodology for analysis of asymmetrical conditions in low-voltage distribution grids with DG, caused by the load and the
DG. Software for simulation of working conditions with different degree of asymmetry has been developed over this
methodology. The aim of the research is to obtain the limits for connecting single phase DG to three-phase distribution
grids, without breaking the valid standards for asymmetry. The results of the simulation of the asymmetry, caused by the
load and the DG in typical branches of low-voltage distribution grids have been analyzed.

description: The concept of the surface of a protein in solution, as well of the interface between protein and 'bulk solution', is introduced. The experimental technique of small angle X-ray and neutron scattering is introduced and described briefly. Molecular dynamics simulation, as an appropriate computational tool for studying the hydration shell of proteins, is also discussed. The concept of protein surfaces with fractal dimensions is elaborated. We finish by exposing an experimental (using small angle X-ray scattering) and a computer simulation case study, which are meant as demonstrations of the possibilities we have at hand for investigating the delicate interfaces that connect (and divide) protein molecules and the neighboring electrolyte solution.

description: This report summarizes national trends in the level and composition of food retail sales associated with the Coronavirus (COVID-19) pandemic. The analysis primarily uses weekly retail-based scanner data that span the start of the pandemic through March 13, 2022. For the first 2 years of the pandemic, between the declaration of the national emergency concerning the pandemic on March 13, 2020, and March 13, 2022, real food retail sales increased by roughly 10 percent compared to pre-pandemic levels. These increases were especially driven by sales of meat products (including beef, pork, and seafood), although the relative composition of food retail sales roughly returned to pre-pandemic makeup as of March 2021. Real food retail sales during the second year of the pandemic, between March 13, 2021, and March 13, 2022, were 6.6 percent higher compared to pre-pandemic levels.

description: Externally applied electromagnetic fields in general have an influence on the width of atomic spectral lines. The decay rates of atomic states can also be affected by the geometry of an applied field configuration giving rise to an imaginary geometric phase. A specific chiral electromagnetic field configuration is presented which geometrically modifies the lifetimes of metastable states of hydrogen. We propose to extract the relevant observables in a realistic longitudinal atomic beam spin-echo apparatus which allows the initial and final fluxes of the metastable atoms to be compared with each other interferometrically. A geometry-induced change in lifetimes at the 5%-level is found, an effect large enough to be observed in an available experiment.

description: Optical frequency combs provide the clockwork to relate optical frequencies to radio frequencies. Hence, combs allow to measure optical frequencies with respect to a radio frequency where the accuracy is limited only by the reference signal. In order to provide a stable link between the radio and optical frequencies, the two parameters of the frequency comb must be fixed: the carrier envelope offset frequency $f_{\rm ceo}$ and the pulse repetition-rate $f_{\rm rep}$. We have developed the first optical frequency comb based on difference frequency generation (DFG) that eliminates $f_{\rm ceo}$ by design - specifically tailored for applications in cold atom physics. An $f_{\rm ceo}$-free spectrum at 1550 nm is generated from a super continuum spanning more than an optical octave. Established amplification and frequency conversion techniques based on reliable telecom fiber technology allow generation of multiple wavelength outputs. In this paper we discuss the frequency comb design, characterization, and optical frequency measurement of Sr Rydberg states. The DFG technique allows for a compact and robust, passively $f_{\rm ceo}$ stable frequency comb significantly improving reliability in practical applications.

description: We study the effects of robot penetration on income inequality in 14 European countries between 2006-2018, a period of rapid adoption of robots. We first use the approach proposed by Acemoglu and Restrepo (2022) to show that, similarly to the US, automation reduced hourly wages and employment in Western Europe, but had no significant effect in Eastern Europe, where labor costs have been noticeably lower. We then use the estimated wage and employment shocks as input to the EUROMOD microsimulation model to assess how robot-driven shocks affected household income inequality. Automation widened income inequality in European countries, but its contribution was very small, about one percent of the recorded change in the Gini index in this period. European countries’ tax and benefit systems absorbed wage and employment shocks caused by automation. Benefits played a larger role, especially in Western Europe. Welfare states appear more effective in mitigating the effects of automation in Europe than in the US.

description: As the production capacity of CdTe PV modules increases beyond 1 GWp, the material sustainability
issues will become a major consideration for cost of production. In order to continue decreasing the cost of thin film PV
one needs to control material utilization in the process moving towards ultra thin film PV. Controlling film thickness
with current deposition techniques, employed in the manufacturing of CdTe PV modules, can be difficult at the micron
level and conventional techniques require a vacuum environment. Atmospheric pressure metal organic chemical vapor
deposition (AP-MOCVD) offers numerous advantages to become a strong contender for inline deposition of thin film
CdTe PV cells. The preliminary results for transferring AP-MOCVD CdTe devices from a horizontal batch reactor to an
inline reactor are reported here. Good controllability over alloying of the CdZnS window layer and CdTe layer thickness
uniformity is demonstrated. Preliminary results show the deposition rate has increased from 30 nm/min to 580 nm/min
with material utilization improving from 5 % in the horizontal reactor to 32 % in the inline reactor. A non-optimized
CdTe cell deposited in the inline reactor has achieved a 8 % conversion efficiency.

description: This work covers outdoor and indoor testing of a CdTe module from First Solar (FS-60). Outdoor
characterisations were performed at PSI’s Solar Test Facility and indoor measurements at SUPSI-ISAAC
Institute, Lugano. The location of PSI represents a typical site in the Swiss midland. The module was exposed
outdoor on a sun tracker and tested under clear sky conditions as well as under a cloudy sky. During testing, the
global-normal irradiance varied between 40 and 1054 W/m2, the cell module temperature between 13 and 68°C,
and the relative air mass between 1.2 and 6.6. About 1360 I-V characteristics were acquired, allowing to plot the
efficiency as a function of irradiance, cell module temperature and air mass. The data were used to validate a new
efficiency model of PSI to calculate the module efficiency under real operating conditions on different sites.
In order to investigate the difference between outdoor and indoor characterisation the module was
measured with a pulsed sun simulator at SUPSI-ISAAC. The module was characterised by measuring the
temperature coefficient and the full temperature-irradiance matrix in the range from 100 to 1000 W/m2 and from
25 to 65°C. Afterwards, the module energy output, under real conditions, was calculated with the energy
prediction methods from PSI and the ‘Matrix-Method’ of SUPSI-ISAAC and the results were compared with the
one year energy output data of the same module measured with the outdoor energy yield facility in Lugano.

Neural Aspect-based Text Generation

Subjects: subject: 80107 Natural Language Processing

description: Advances in neural sequence models and large-scale pre-trained language models have made a great impact on natural language generation, achieving impressive performance on different tasks. However when users of such systems have a specific interest in what content to generate, these models fail to address such needs. To control the content of the generated text more accurately, one could specify an aspect of interest, a semantic property of a current topic that specifies a particular subset of content, and perform aspect-based generation. For example, a user may be interested in knowing more about price from the collection of product reviews. Despite the potential utility of such methods, aspect-based generation has received relatively little research attention. One of the reasons is the lack of available data resources to train and apply models in a variety of domains. In addition, what little work exists on aspect-based generation describes these aspects in simple forms: a set of labels that specifies the overall subtopics in the generated text. However, in reality the content of a text should be specified with different granularities and with respect to other aspects of interest when necessary. In this thesis, we propose methods to address these issues, allowing for better control of the generated texts. This thesis consists of three parts. First, we address the lack of domain diversity in data sources for aspect-based summarization by reformulating Wikipedia article generation as multi-document aspect-based summarization. We examine the summarization performance on 20 domains and highlight domain-specific challenges. Leveraging this dataset, we then explore zero-shot domain transfer of aspect-based summarization models, with models capable of handling arbitrary aspects at testing time. Next, we focus on incorporating structures into aspects. In this part, we turn our focus to scientific survey articles, which are organized by human authors using section structures. Using this structure, we formulate survey article generation as a summarization task and investigate the use of structural prompts for aspect-based summarization. In the last part, we aim to achieve fine-grained content control with fine-grained aspects. In particular, we learn a language model on Wikipedia texts about single entities by conditioning on a local knowledge base that stores information about various aspects of the entities. We design a model capable of automatically switching between token-by-token and aspect-based generation based on the likelihood of the text.

description: Grand canonical Monte Carlo simulation results are reported for an electric double layer modelled by a planar charged hard wall, anisotropic shape cations, and spherical anions at different electrolyte concentrations and asymmetric valencies. The cations consist of two tangentially tethered hard spheres of the same diameter, $d$. One sphere is charged while the other is neutral. Spherical anions are charged hard spheres of diameter $d$. The ion valency asymmetry 1:2 and 2:1 is considered, with the ions being immersed in a solvent mimicked by a continuum dielectric medium at standard temperature. The simulations are carried out for the following electrolyte concentrations: 0.1, 1.0 and 2.0 M. Profiles of the electrode-ion, electrode-neutral sphere singlet distributions, the average orientation of dimers, and the mean electrostatic potential are calculated for a given electrode surface charge, $σ$, while the contact electrode potential and the differential capacitance are presented for varying electrode charge. With an increasing electrolyte concentration, the shape of differential capacitance curve changes from that with a minimum surrounded by maxima into that of a distorted single maximum. For a 2:1 electrolyte, the maximum is located at a small negative $σ$ value while for 1:2, at a small positive value.

description: Agricultural productivity growth helps farmers meet the food and fiber demands of growing global populations while using relatively fewer resources. One of the most informative measures of agricultural productivity is total factor productivity (TFP), which measures the efficiency with which agricultural inputs are combined to produce output. Unlike single factor productivity measures, such as output per acre (yield) for land, total factor productivity compares total crop, livestock, and aquaculture output with the full set of inputs used in agricultural production. When the total value of agricultural output grows faster than the total amount of inputs used, then TFP increases.

description: The mechanisms of emission and changes in rotation frequency ('glitching') of the Vela pulsar (J0835-4510) are not well understood. Further insight into these mechanisms can be achieved by long-term studies of integrated pulse width, timing residuals, and bright pulse rates. We have undertaken an intensive observing campaign of Vela and collected over 6000 hours of single pulse data. The data shows that the pulse width changes with time, including marked jumps in width after micro-glitches (frequency changes). The abundance of bright pulses also changes after some micro-glitches, but not all. The secular changes in pulse width have three possible cyclic periods, that match with X-ray periodicities of a helical jet that are interpreted as free precession.

description: We fabricate a liquid-core liquid-clad microcavity that is coupled to a standard tapered fiber, and then experimentally map the whispering-gallery modes of this droplet resonator. The shape of our resonator is similar to a thin prolate spheroid, which makes space for many high-order transverse modes, suggesting that some of them will share the same resonance frequency. Indeed, we experimentally observe that more than half of the droplet's modes have a sibling having the same frequency (to within linewidth) and therefore exhibiting a standing interference-pattern.
title: The technique of the novel from French West Africa 1926 to 1969
Creators: name: Dick, Roland
Publisher: name: University of Kent
Year: 2022

description: The emergence of francophone literature in French West Africa over the last fifty years poses questions for the student of literature. How should he approach it? If he attempts to describe and evaluate it, in what terms should he do so? Is it to be thought of as a branch of African literature in French, or of French literature in Africa? The creative writing of the area has been mainly in the novel and in poetry; in considering, as this thesis does, the novel only, what is the relevance of Western novel criticism? Can one define a novel? Can one define a good novel? Such are the questions behind the title of this thesis, The Technique of the Novel from French West Africa, 1926 to 1969. The nature of the novel is notoriously difficult to state: nevertheless, insofar as the field under study has sought expression within a traditional novel form, that of telling the story of a life or of a situation, it becomes subject to the commonplace description of a novel in terms of characterisation, intrigue, milieu and prose style. These lines of approach are therefore used here. Representative and outstanding novels are considered as wholes in respect of the nature and role of these elements within the novels. It seems axiomatic that the life of a field of literature over a period of time lies in the inter-action of the processes of imitation and innovation. This process is considered within the two main sub-groups into which the field naturally falls, the biographical and the situational narrative. One powerful force in favour of imitation is the socio-political reality in which the educated young African stands. From the origin of this literature until Independence the colonial presence ?KA acted as an unavoidable irritant insisting that literature be externally orientated. Hence come the contemporaneity and similarity of so much of the field's thematic material, concerned to register protest or to preserve a disappearing image. The idea of a personal or of a universal literature has remained remote under the pressure of new social problems. Innovation has taken place to a limited extent within the stereotyped framework of the exploited African, as some authors offer the experience of a vicarious revanche unlikely in reality. In terms of external form, one author has experimented with a melange des genres, another derives his ideas from Kafka and in several the prose style stands as an important original component of the novel's effect. Variety is, however, largely provided by the many presentations of different kinds of milieu. The very few works which see man as universal, either predator or outsider or mortal, and seem to exist in their own right, set new standards for the field as it outgrows its autobiographical need and its cries of protest.

description: Research on solar energy conversion into thermal or electrical energy represents an European priority,
offering clean alternatives to the use of fossil fuels.
Optimization of the energy efficiency for the conversion systems can be achieved by using performant materials or by
increasing the degree of use of the solar radiation. This last goal can be reached by adapting to the geographic and
climatic regional specific and, mainly, by using tracking systems for the active elements (solar collectors,
photovoltaic modules) of the conversion systems.
This paper presents the development of a mechanical configuration destined to track the sun path. The mechanical
system is based on a dual axis orientation mechanism for a PV platform, designed in order to increase the efficiency
of the conversion system.
The system is an example of mechanical virtual prototyping for a tracked PV platform and represents one sub-system
in a complex virtual prototyping platform, aiming to offer a fast design tool of a PV system, considering the input
data (solar radiation) up to the output response (generated power).
The implemented infrastructure consists in a PV platform dual axis tracked system, stationary reference PV panels,
storage system and data acquisition system integrated in a complex concept for a testing laboratory.

description: The performance analysis of a PV module or PV system is based on the I-V characterization of these components in
dependence of several parameters like solar irradiance, module operating temperature, solar spectrum, solar angle-ofincidence,
ambient temperature, wind speed, humidity. Several I-V curve tracers for single module or multi-tracers controller
are available on the market for both spot I-V characterization or long term operative performance acquisition, but new and
innovative test methods and analytical procedures are needed in order to assure high quality and reliability of measurements,
mainly when the synchronism of the measurement of the I-V characteristic with other measured parameters (global and
direct incident light, module temperature, sun spectrum, etc) is very relevant. In fact for PV-Concentrator modules the I-V
curve needs to be acquired in very short time to avoid hot spot on the solar receivers , while the synchronism of
measurement is very relevant to mitigate undesirable effects due to optical misalignments, thermal expansions and
mechanical stresses usually change planarity of module surface and tracking reference plane. The proposed characterization
tool PV-INTRASCAN® [3] allows at low cost, in very easy way by modular approach, to perform, in short time, complete
campaigns of measurements for the acquisition of performance analysis of PV modules, PV-String and PV-Systems ranging
from few Wp up to MWp for both PV flat or PV concentration systems.

description: Splitting methods constitute a well-established class of numerical schemes for the time integration of partial differential equations. Their main advantages over more traditional schemes are computational efficiency and superior geometric properties. In the presence of non-trivial boundary conditions, however, splitting methods usually suffer from order reduction and some additional loss of accuracy. For diffusion-reaction equations with inhomogeneous oblique boundary conditions, a modification of the classic second-order Strang splitting is proposed that successfully resolves the problem of order reduction. The same correction also improves the accuracy of the classic first-order Lie splitting. The proposed modification only depends on the available boundary data and, in the case of non Dirichlet boundary conditions, on the computed numerical solution. Consequently, this modification can be implemented in an efficient way, which makes the modified splitting schemes superior to their classic versions. The framework employed in our error analysis also allows us to explain the fractional orders of convergence that are often encountered for classic Strang splitting. Numerical experiments that illustrate the theory are provided.

description: Skyline Solar has developed a novel High Gain Solar Array (HGS) which operates at medium concentration levels. The
holistic design balances manufacturability, performance, reliability and cost. Development has been guided by both a
Levelized Cost Of Energy (LCOE) tool and a performance predicting tool that relates the component characteristics to
the system energy production. The novelty of this tool relative to those currently available is that it accurately captures
the performance effects of non linearity from environmental conditions - such as weather patterns - and the value of
energy as a function of time of day and season. The tool combines outside tests over a broad range of environmental
conditions, finite element analysis, analytical sub-models and manufacturing variability analysis. It highlights trade-offs
between energy production vs. cost as well as energy production estimates as a function of the location of the system.
This paper outlines the key elements in the design of Skyline High Gain Solar Array, the design of the performance
predictive tool and examples of the optimization process.

description: Spectral line survey observations of 7 molecular clouds in the Large Magellanic Cloud (LMC) have been conducted in the 3 mm band with the Mopra 22 m telescope to reveal chemical compositions in low metallicity conditions. Spectral lines of fundamental species such as CS, SO, CCH, HCN, HCO+, and HNC are detected in addition to those of CO and 13CO, while CH3OH is not detected in any source and N2H+ is marginally detected in two sources. The molecular-cloud scale (10 pc scale) chemical composition is found to be similar among the 7 sources regardless of different star formation activities, and hence, it represents the chemical composition characteristic to the LMC without influences of star formation activities. In comparison with chemical compositions of Galactic sources, the characteristic features are (1) deficient N-bearing molecules, (2) abundant CCH, and (3) deficient CH3OH. The feature (1) is due to a lower elemental abundance of nitrogen in the LMC, whereas the features (2) and (3) seem to originate from extended photodissociation regions and warmer temperature in cloud peripheries due to a lower abundance of dust grains in the low metallicity condition. In spite of general resemblance of chemical abundances among the seven sources, the CS/HCO+ and SO/HCO+ ratios are found to be slightly higher in a quiescent molecular cloud. An origin of this trend is discussed in relation to possible depletion of sulfur along molecular cloud formation.

description: We present the discovery in Kepler's $K2$ mission observations and our follow-up radial velocity observations from Keck/HIRES for four eclipsing binary (EB) star systems in the young benchmark Pleiades cluster. Based on our modeling results, we announce two new low mass ($M_{tot} < 0.6 M_\odot$) EBs among Pleiades members (HCG 76 and MHO 9) and we report on two previously known Pleiades binaries that are also found to be EB systems (HII 2407 and HD 23642). We measured the masses of the binary HCG 76 to $\lesssim$2.5% precision, and the radii to $\lesssim$4.5% precision, which together with the precise effective temperatures yield an independent Pleiades distance of 132$\pm$5 pc. We discuss another EB towards the Pleiades that is a possible but unlikely Pleiades cluster member (AK II 465). The two new confirmed Pleiades systems extend the mass range of Pleiades EB components to 0.2-2 $M_\odot$. Our initial measurements of the fundamental stellar parameters for the Pleiades EBs are discussed in the context of the current stellar models and the nominal cluster isochrone, finding good agreement with the stellar models of Baraffe et al. (2015) at the nominal Pleiades age of 120 Myr. Finally, in the Hyades, we report a new low mass eclipsing system (vA 50) that was concurrently discovered and studied by Mann et al. (2016). We confirm that the eclipse is likely caused by a Neptune-sized transiting planet, and with the additional radial velocity constraints presented here we improve the constraint on the maximum mass of the planet to be $\lesssim$1.2 $M_\mathrm{Jup}$.

description: We present a comprehensive set of spatially resolved, integral field spectroscopic mapping of the Wolf-Rayet planetary nebula Th 2-A, obtained using the Wide Field Spectrograph on the Australian National University 2.3-m telescope. Velocity-resolved H$α$ channel maps with a resolution of 20 km s$^{-1}$ allow us to identify different kinematic components within the nebula. This information is used to develop a three-dimensional morpho-kinematic model of the nebula using the interactive kinematic modeling tool SHAPE. These results suggest that Th 2-A has a thick toroidal shell with an expansion velocity of 40 $\pm$ 10 km s$^{-1}$, and a thin prolate ellipsoid with collimated bipolar outflows toward its axis reaching velocities in the range of 70-110 km s$^{-1}$, with respect to the central star. The relationship between its morpho-kinematic structure and peculiar [WO]-type stellar characteristics deserves further investigation.

description: The purpose of this work is to evaluate the most appropriate way of recycling silicon kerf obtained
during diamond wire slicing of silicon. Compared to prior art, our work consists in finding the best combination of
silicon purification and cost of ownership for the recycling process, not necessarily to obtain the most purified silicon
to be further processed. The recycling of silicon by using it as feedstock back in the silicon ingot manufacturing chain
can be done at different manufacturing steps.

description: The Strategic Research Agenda of the European Photovoltaic Technology Platform has been updated
to include new cost and performance targets, together with revised research priorities. This reflects the progress in the PV
market, advances in PV R&D and the increased ambitions for PV contribution to Europe’s electricity supply since the
publication of the first SRA four years ago. This paper discusses the approach taken and summarises the main differences
between the new and old versions. It highlights the research priorities across the range of PV device technologies and at
PV system level.

description: We have successfully prepared high-density Cu(In,Ga)Se2 (CIGS) films by a newly developed“Printing and Highpressure
Sintering (PHS)” process. First, we prepared fine CIGS powder suitable for screen printing using a
mechanochemical synthesis and wet ball-milling. Particulate precursors were deposited in a layer by a screen-printing
technique, and the porous precursor layer was sintered into a dense polycrystalline film by high-pressure sintering in
an N2 gas atmosphere. The surface and cross-sectional microstructures of the CIGS films fabricated on a Mo-coated
soda-lime glass substrate were observed in a scanning electron microscope (SEM). The CIGS films have a thickness
of about 2 µm and high-density microstructure comparable to the CIGS film deposited by physical vapor deposition
(PVD). The optical properties of the CIGS films deposited on soda-lime glass substrate were measured by NIR-VISUV-
spectroscopy. The present CIGS films had over 50% transmittance at a wavelength of about 1,500 nm. The CIGS
solar cell showed an efficiency of 3.2% with a Voc of 0.284V, a Jsc of 26.2mA/cm2 and a fill factor of 0.429.

description: China has been a central player in global markets for cotton and textiles since the early 2000s, but trade patterns established decades ago are being disrupted by the changing economics of cotton production and textile manufacturing in that country. One of the factors shaking up the industry is that Chinese officials have been shifting the country’s cotton production to the remote Xinjiang Uyghur Autonomous Region. Known simply as “Xinjiang,” this provincial region in northwest China borders several Central and South Asian countries and contains a large population of Uyghurs and other minority ethnic groups.
Analytical study on parameter regions of dynamical instability for two-component Bose--Einstein condensates with coaxial quantized vortices

description: The dynamical instability of weakly interacting two-component Bose--Einstein condensates with coaxial quantized vortices is analytically investigated in a two-dimensional isotopic harmonic potential. We examine whether complex eigenvalues appear on the Bogoliubov--de Gennes equation, implying dynamical instability. Rather than solving the Bogoliubov--de Gennes equation numerically, we rely on a perturbative expansion with respect to the coupling constant which enables a simple, analytic approach. For each pair of winding numbers and for each magnetic quantum number, the ranges of inter-component coupling constant where the system is dynamically unstable are exhaustively obtained. Co-rotating and counter-rotating systems show distinctive behaviors. The latter is much more complicated than the former with respect to dynamical instability, particularly because radial excitations contribute to complex eigenvalues in counter-rotating systems.

description: Solar power appears to be one of the most promising resources to meet the medium and long term
renewable energy targets. The integration of large amounts of photovoltaic (PV) generation into distribution networks
faces some limitations due to the network constraints. The PV community became well aware of these limitations in
the last years. While first solutions have been pointed out mainly for large installations connected to the medium
voltage network, the specificities of low voltage networks are still not fully understood. This paper aims at explaining
the challenges associated to the planning and operation of low voltage network with high PV penetration. The actual
impact of PV infeed is quantified on the basis of real and accurate network, load and generation data. Results from
unsymmetrical load-flow computations are presented and the implementation of reactive power-based voltage control
is shortly discussed.

description: Photovoltaic Research Infrastructures were set up throughout all Europe. Some of them are very
unique, others are very similar. A coordinated approach of these Research Infrastructures should end up with an
optimisation of the benefits and value they can provide. In one hand, organising an access to some outstanding
facilities may be more efficient than investing again into a similar facility. In the other hand, harmonising the criteria,
the test procedures, or the modelling interfaces among similar Research Infrastructures may help in accelerating
knowledge acquisition due to easier benchmarking and availability of more case studies for some validation.
Twenty research organisations are committed to this goal through the Sophia project, funded by the European
Commission. This paper describes the organisation and the activities which have just started.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1930-1933
description: MG Si can be effectively purified using a fractional melting process. In the fractional melting process,
impurities in silicon concentrate, melt, and form a network. When the impurities concentrate with temperature
increase, they coalesce at preferred sites like GBs, pores, and cracks. The metal impurity behaviors of MG Si were
studied during fractional melting process. The change of the microstructure during the process was observed with a
SEM and the surface distribution kept a close watch with an EPMA. The affinity between impurities was investigated
by calculation according to the extended Miedema model. Of impurities in silicon, Al and Ca have similar behaviors
and Fe and Ti are similar, too.

description: This paper describes a new method for the crystallization of silicon sheet using an electrically
generated molten line. A thin molten line is created in the sample by applying an electric current and then, using a
suitable external thermal gradient, it is forced to travel across the sample crystallizing it. The crystallized sample has
columnar cm-sized crystal grains and minority carrier lifetimes of a few microseconds, similar to comparable
crystallization techniques.
