description: The most diffused architecture for p-type silicon based solar cells presents the back contact formed by
screen printed aluminium, which also provides Back Surface Field. To connect cells in series into modules, and since
aluminium is not solderable, it is used to introduce on the cells backside some zones of silver, which are overlapped
with the aluminium, to ensure the current transport. In this paper we investigate the silver/aluminium interface,
especially when different backside layouts are adopted, and we correlate its influence on the electrical performances
of solar cells with different silver paste compositions.

description: Thermal donors are a typical defect in oxygen-rich Czochralski silicon (Cz-silicon). In this work the
influence of thermal donors on minority carrier lifetime in n-type Cz-silicon is investigated. Even if thermal donors
might be destroyed by typical high temperature steps during cell processing they reduce the carrier lifetime in the asgrown
state. This leads to an underestimation of minority carrier lifetime in as-grown n-type silicon when high
thermal donor concentrations are present. In this study the lifetime reduction due to thermal donors is analyzed based
on their density of states in the silicon band gap. The determined parameters allow a simple estimation of the bulk
lifetime after thermal donor annealing when the as-grown lifetime and the resistivity of the material are known.

description: Laser ablation of SiNx layers on silicon surface offer an attractive way forming front side grid pattern
to achieve alternative metallization like Light Induced Plating (LIP) contact in solar cell fabrication. A critical factor
in adapting laser processes into production is the optimization of processing condition to minimize the damage of the
emitter underneath. In this work, we investigate laser ablation of SiNx layer on the silicon surface for various laser
pulse energy using nanosecond laser with wavelength of 532 nm. The four-point probe, Electrochemical capacitance
voltage (ECV), and Field Emission Scanning Electron Microscope (FESEM) have been used, respectively, to
characterize the sheet resistance, doping profile of underlying phosphorus emitter and morphological properties of
laser transformed area at varying pulse energy. Our result shows that the thermal effect of laser at different pulse
energy affected not only the doping depth but also the amount of active phosphorus atoms in the emitter region
during the laser ablation of SiNx. The Suns-Voc measurement reveals the impact of the laser ablation on the electrical
properties of the solar cell. Further discussion of laser ablation mechanism is proposed.

description: We proposed a novel Al fire through paste for aluminum oxide (Al2O3) passivation. We fabricated
passivated emitter and rear cell (PERC) with10 or 30-nm-thick Al2O3 passivation film. The emitter layers were
formed by POCl3 diffusion. For the front passivation, hydrogen-containing silicon nitride (SiNx:H) thin passivation
layer was deposited. For rear side, Al2O3 film was deposited by ozone based batch-type atomic layer deposition
(ALD) system. Front and back side electrodes were simultaneously formed by fire through after screen printing. The
novel Al paste had fire through properties. Thus, we succeed to fabricate the PERC with Al2O3 passivation by fire
through process.

 Abstract
 Biochar is a promising material for facilitating the remediation of aqueous phase contaminated with toxic trace metals. However, biochar properties from lignocellulosic biomass such as giant reed is underexplored. The sorption of Pb2+ by biochar produced from giant reed at different temperature profiles were studied. Two biochar of temperature 300 °C and 500 °C were studied. The prepared biochar was characterized using X-Ray Diffraction, BET Surface Area and Pore Analyser, Scanning Electron Microscopy, CHN Analyser and electrostatic Zeta Potential. Results showed that biochar produced at 300 °C was effective than that produced at 500 °C in the removal of Pb2+ from aqueous phase. Solution pH showed strong effect on the adsorption ability of GR 300 °C to the Pb2+, the maximum adsorption capacity (19.2 mg g-1) was found to occur under these conditions (Temp. 25 °C, Pb2+ conc. 40 mg/ L, stirring rate 60 rpm, biochar dosage of 0.1 g, in 24 h). The equilibrium data were adequately fitted to Freundlich and Langmuir. GR 300 fitted best to Freundlich model with R2 = 0.89, while GR 500 fitted well to Langmuir of R2 = 0.521. The rate of adsorption was best described by Pseudo-second order model (R2 =1). FTIR analysis and batch experiments results suggested that Pb2+ adsorption mechanism was dominated by complexation with active surface functional groups, precipitation and cationic exchange. Experimental model results suggested that giant reed-derived biochar has high adsorption capacity for Pb2+ compared to other plants biochar reported in other literature.

description: Magnetic fields have been detected in several hundred white dwarfs, with strengths ranging from a few kG to several hundred MG. Only a few of the known fields have a mean magnetic field modulus below about 1 MG. We are searching for new examples of magnetic white dwarfs with very weak fields, and trying to model the few known examples. Our search is intended to be sensitive enough to detect fields at the few kG level. We have been surveying bright white dwarfs for very weak fields using spectropolarimeters at the Canada-France-Hawaii telescope, the William Herschel telescope, the European Southern Observatory, and the Russian Special Astrophysical Observatory. We discuss in some detail tests of the WHT spectropolarimeter ISIS using the known magnetic strong-field Ap star HD 215441 (Babcock's star) and the long-period Ap star HD 201601 (gamma Equ). We report the discovery of a field with a mean field modulus of about 57 kG in the white dwarf LTT 16093 = WD2047+372. The field is clearly detected through the Zeeman splitting of Halpha seen in two separate circularly polarised spectra from two different spectropolarimeters. Zeeman circular polarisation is also detected, but only barely above the 3 sigma level. The discovery of this field is significant because it is the third weakest field ever unambiguously discovered in a white dwarf, while still being large enough that we should be able to model the field structure in some detail with future observations.

description: The lutetium dihydride LuH2 is stable at ambient conditions. Here we show that its color undergoes sequential changes from dark blue at ambient pressure to pink at ~2.2 GPa and then to bright red at ~4 GPa upon compression in a diamond anvil cell. Such a pressure-induced color change in LuH2 is reversible and it is very similar to that recently reported in the N-doped lutetium hydride. However, our preliminary resistance measurements on LuH2 under pressures up to 7.7 GPa evidenced no superconductivity down to 1.5 K.

description: We report on an experimental study of nanostructuring of silicon solar cells using reactive ion etching
(RIE). A simple mask-less, scalable RIE nanostructuring of the solar cell surface is shown to reduce the AM1.5-weighted
average reflectance to a level below 1 % in a fully optimized RIE texturing, and thus holds a significant potential for
improvement of the cell performance compared to current industrial standards. The reflectance is shown to remain below
that of conventional textured cells also at high angle of incidence. The process is shown to be equally applicable to
mono-, multi- and quasi-mono-crystalline Si. The process was successfully integrated in fabrication of solar cells using
only industry standard processes on a Czochralski (CZ) silicon starting material. The resulting cell performance was
compared to cells with conventional texturing. For cells, where the nanostructuring was not fully optimized (reflectance
larger than 2 %), an efficiency of 16.5 % at 1 sun was demonstrated.

description: The ubiquity of turbulent flows in nature and technology makes it of utmost importance to fundamentally understand turbulence. Kolmogorov's 1941 paradigm suggests that for strongly turbulent flows with many degrees of freedom and its large fluctuations, there would only be \emph{one} turbulent state as the large fluctuations would explore the entire higher-dimensional phase space. Here we report the first conclusive evidence of multiple turbulent states for large Reynolds number $\text{Re}=\mathcal{O}(10^6)$ (Taylor number $\text{Ta}=\mathcal{O}(10^{12})$) Taylor-Couette flow in the regime of ultimate turbulence, by probing the phase space spanned by the rotation rates of the inner and outer cylinder. The manifestation of multiple turbulent states is exemplified by providing combined global torque and local velocity measurements. This result verifies the notion that bifurcations can occur in high-dimensional flows i.e. very large $\text{Re}$) and questions Kolmogorov's paradigm.

description: A significant improvement of silicon solar cells can be achieved when an effective back contact is
used. In this work, laser-fired contacts (LFC) have been analysed as low-temperature back contacts for rearpassivated
silicon-heterojunction solar cells. Layers of intrinsic hydrogenated amorphous silicon, (i)a-Si:H, deposited
by plasma-enhanced chemical-vapour deposition (PECVD) have been used as dielectrics in order to passivate the
back surface of p-CZ (Czochralski) polished monocrystalline silicon wafers. The quality of these (i)a-Si:H layers has
been evaluated as a function of their PECVD deposition parameters and their thicknesses (from 100 to 250 nm). Then
an aluminium (Al) back contact has been thermally evaporated. A ns-pulsed Nd:YVO4 laser beam, =532 nm, has
been used to fire the Al through the (i)a-Si:H layer to create the rear-point LFC back contacts. To obtain low-ohmicresistance
back contacts, the irradiation parameters have been adjusted for each (i)a-Si:H thickness. Finally, silicon
heterojunction solar cells (SHJ) with laser-fired back contacts with different contacted area have been evaluated.
Annealing treatments have been needed to improve the devices.
Galactic Energetic Particles and Their Radiative Yields in Clusters

description: As energetic particles diffuse out of radio and star-forming galaxies (SFGs), their intracluster density builds up to a level that could account for a substantial part or all the emission from a radio halo. We calculate the particle time-dependent, spectro-spatial distributions from a solution of a diffusion equation with radio galaxies as sources of electrons, and SFGs as sources of both electrons and protons. Whereas strong radio galaxies are typically found in the cluster (e.g., Coma) core, the fraction of SFGs increases with distance from the cluster center. Scaling particle escape rates from their sources to the reasonably well determined Galactic rates, and for realistic gas density and magnetic field spatial profiles, we find that predicted spectra and spatial profiles of radio emission from primary and secondary electrons are roughly consistent with those deduced from current measurements of the Coma halo (after subtraction of emission from the relic Coma A). Nonthermal X-ray emission is predicted to be mostly by Compton scattering of electrons from radio galaxies off the CMB, whereas $γ$-ray emission is primarily from the decay of neutral pions produced in interactions of protons from SFGs with protons in intracluster gas.

description: The polar transformation of a binary erasure channel (BEC) can be exactly approximated by other BECs. Arıkan proposed that polar codes for a BEC can be efficiently constructed by using its useful property. This study proposes a new class of arbitrary input generalized erasure channels, which can be exactly approximated the polar transformation by other same channel models, as with the BEC. One of the main results is the recursive formulas of the polar transformation of the proposed channel. In the study, we evaluate the polar transformation by using the $α$-mutual information. Particularly, when the input alphabet size is a prime power, we examines the following: (i) inequalities for the average of the $α$-mutual information of the proposed channel after the one-step polar transformation, and (ii) the exact proportion of polarizations of the $α$-mutual information of proposed channels in infinite number of polar transformations.

description: DC magnetron sputtered Indium-Tin-Oxide (ITO) thin films were produced using state of the art high
density rotary sintered ceramic ITO targets which yield uniform large area coatings. Deposition parameters have been
chosen in order to fulfill the restrictions imposed by heterojunction a-Si/c-Si solar cells. Because of the pressure in
the solar industry on manufacturing costs, rotary ITO sputtering targets which offer the potential to improve target
utilization by a factor of 2.5, and associated overall coating cost improvements by 25-40 %, have been the focus of
this study. A direct comparison of electrical and optical performance of ITO thin films produced from ceramic
sputtering targets with SnO2 concentrations of 0, 3, 5 and 10 wt% is made in this paper. To our knowledge this is the
first time the electro-optical performance of thin films produced from ceramic ITO sputtering targets with the above
mentioned compositions and using identical industrial scale deposition conditions have been directly compared using
typical heterojunction a-Si/c-Si cell parameters. Electrical Hall properties are compared with optical absorption
curves in the visible and near infrared (NIR) for depositions with various Ar, O2 and H2 gas mixtures as a function of
SnO2 concentration to identify the most suitable grade for a heterojunction a-Si/c-Si cell application. It was found
that Sn- doped ITO containing 3 wt% SnO2 is the best alternative for replacing ITO-90/10 because of its superior
optical characteristics at an acceptable conductivity, when using Ar/H2-Ar/O2 gas mixture during the deposition
process.

description: Gamma-ray bursts (GRBs) are short and intense flashes at the cosmological distances, which are the most luminous explosions in the Universe. The high luminosities of GRBs make them detectable out to the edge of the visible universe. So, they are unique tools to probe the properties of high-redshift universe: including the cosmic expansion and dark energy, star formation rate, the reionization epoch and the metal evolution of the Universe. First, they can be used to constrain the history of cosmic acceleration and the evolution of dark energy in a redshift range hardly achievable by other cosmological probes. Second, long GRBs are believed to be formed by collapse of massive stars. So they can be used to derive the high-redshift star formation rate, which can not be probed by current observations. Moreover, the use of GRBs as cosmological tools could unveil the reionization history and metal evolution of the Universe, the intergalactic medium (IGM) properties and the nature of first stars in the early universe. But beyond that, the GRB high-energy photons can be applied to constrain Lorentz invariance violation (LIV) and to test Einstein's Equivalence Principle (EEP). In this paper, we review the progress on the GRB cosmology and fundamental physics probed by GRBs.

description: We developed a simple method to evaluate if a capping layer of a rear-passivated silicon solar cell
maintains its integrity through the high-temperature metallization step. Test specimens are prepared by depositing
dielectric layers on the front and the back of 180 μm-thick saw-damage-etched p-type Cz silicon wafers. Some of the
samples are first passed through a firing belt furnace without metallization. The remaining samples then undergo fullarea
aluminum (Al) screen-printing on the back, without a prior contact-opening step, and finally they are fired with
the belt furnace for metallization. We measure the minority-carrier lifetimes after the firing step and calculate the
surface recombination velocity. The SRV values for the measured samples allow us to deduce (1) if the dielectric
stack is compatible with the high-temperature firing step, and also (2) if the stack provides sufficient protection
against the Al metallization. 21.0% conversion efficiency was achieved with the PERL structure on commercialgrade
239 cm2 boron-doped Cz Si wafers, with the rear passivation stack engineered with the presented method.

description: We have established simplified L-BSF (Localized Back Surface Field) fabrication process using screen
printing method, which is suitable for mass production. It consists of 5 steps, i.e., EP (etching paste) screen printing,
heating, cleaning, Al paste screen printing and firing. EP can remove the passivation and capping layer under the
paste without any deterioration of Si substrate. And subsequent Al paste screen printing and firing can make good
contact and high quality L-BSF only underneath the contact hole without any deterioration of passivation layer on
other part of the rear surface. In conclusion, we were able to make L-BSF structure with good contact, high quality
passivation and high internal reflectance of rear surface using only screen printing method, which is suitable for mass
production.

description: Die Studie stellt die Frage nach dem Beitrag erzählender Literatur zu einem Dialog über Formen der Gewalt im gesellschaftlichen Raum Frankreich zu Beginn des 21. Jahrhunderts. Unter Rückgriff auf Bourdieu’sche Konzepte literatursoziologischer Theorie diskutiert sie zunächst die für ein sozialwissenschaftlich relevantes Erfassen des Wissens von Literatur notwendige Perspektive auf erzählte Gewalt. Bei dem dafür untersuchten Text-Korpus handelt es sich um vielrezipierte Erzähltexte des literarischen Feldes in Frankreich, welche größtenteils in der zweiten Dekade des 21. Jahrhunderts erschienen sind. Ausgehend von theoretischen Überlegungen zu Grenzen und Möglichkeiten einer solchen feldsoziologischen Fokussierung auf die Literatur der unmittelbaren Gegenwart wird am konkreten Textmaterial und mit den Mitteln der Literaturwissenschaft untersucht, wie und warum die französische Literatur über unterschiedliche Formen von Gewalt, vom Erinnern an die historisch gewordenen Gewalttraumata des 20. Jahrhunderts, vom Terrorismus des 21. Jahrhunderts, von Rassismus und Klassismus der Gegenwart, von Femiziden und Homophobie, über «Abgehängte» in ländlichen Gebieten, aber auch im Zentrum der Metropole, über Arbeitslosigkeit und Armut in Frankreich erzählt.

description: A process for silicon solar cell fabrication associated with self–aligned Ni/Cu metallization is
demonstrated with a reduced number of technological steps. After laser ablation of the anti-reflection coating, a
nickel seed layer is formed by electroless chemical deposition followed by copper light-induced plating. Laboratory
size solar cells were fabricated with different metal finger widths and spacings to evaluate the viability of the process.
The best efficiency measured on 4 cm2 multi-crystalline solar cells was of the order of 16.5%. The limiting factors as
well as possible improvements of the overall process are discussed.

description: Enriched by natural language texts, Stack Overflow code snippets are an invaluable code-centric knowledge base of small units of source code. Besides being useful for software developers, these annotated snippets can potentially serve as the basis for automated tools that provide working code solutions to specific natural language queries. With the goal of developing automated tools with the Stack Overflow snippets and surrounding text, this paper investigates the following questions: (1) How usable are the Stack Overflow code snippets? and (2) When using text search engines for matching on the natural language questions and answers around the snippets, what percentage of the top results contain usable code snippets? A total of 3M code snippets are analyzed across four languages: C\#, Java, JavaScript, and Python. Python and JavaScript proved to be the languages for which the most code snippets are usable. Conversely, Java and C\# proved to be the languages with the lowest usability rate. Further qualitative analysis on usable Python snippets shows the characteristics of the answers that solve the original question. Finally, we use Google search to investigate the alignment of usability and the natural language annotations around code snippets, and explore how to make snippets in Stack Overflow an adequate base for future automatic program generation.

description: We present first results from a program of Atacama Large Millimeter/submillimeter Array (ALMA) CO(2-1) observations of circumnuclear gas disks in early-type galaxies. The program was designed with the goal of detecting gas within the gravitational sphere of influence of the central black holes. In NGC 1332, the 0.3"-resolution ALMA data reveal CO emission from the highly inclined (i~ 83 degrees) circumnuclear disk, spatially coincident with the dust disk seen in Hubble Space Telescope images. The disk exhibits a central upturn in maximum line-of-sight velocity reaching +-500 km/s relative to the systemic velocity, consistent with the expected signature of rapid rotation around a supermassive black hole. Rotational broadening and beam smearing produce complex and asymmetric line profiles near the disk center. We constructed dynamical models for the rotating disk and fitted the modeled CO line profiles directly to the ALMA data cube. Degeneracy between rotation and turbulent velocity dispersion in the inner disk precludes the derivation of strong constraints on the black hole mass, but model fits allowing for a plausible range in the magnitude of the turbulent dispersion imply a central mass in the range ~(4-8)x10^8 Msun. We argue that gas-kinematic observations resolving the black hole's projected radius of influence along the disk's minor axis will have the capability to yield black hole mass measurements that are largely insensitive to systematic uncertainties in turbulence or in the stellar mass profile. For highly inclined disks, this is a much more stringent requirement than the usual sphere-of-influence criterion.

description: The photovoltaic characteristics of amorphous/crystalline silicon hetero-junction solar cells are strictly
related to the electronic quality of the junction interface. In this paper we investigate the effect hydrogen plasma
treatments performed on thin amorphous silicon buffer layer deposited over crystalline silicon surface. In particular
we propose the use of surface photovoltage technique as a contact-less tool for the evaluation of the energetic
distribution of the state density at amorphous/crystalline silicon interface. The measurement results have been
compared with those obtained on the same structure after thermal annealing on the interface. We found that both
processes bring to a reduction of the state density of about one order of magnitude, but while the thermal annealing
produces a metastable state which goes back to the initial state after just 48 hours, the effect of hydrogen plasma posttreatment
results much more stable.

description: This paper surveyed the formation of p+ emitter in n-type Si solar cells using different boron sources. We
used BBr3 closed tube furnace and spin-coating boron source, and tuned process parameters including temperature and
duration of various process steps (deposition, drive-in, and oxidation). The p+ emitter Rsheet was around 60-70ohm/sq
for different sample groups. After BBr3 diffusion, the effective lifetime is around 30-40us. The samples with spincoated
boron source showed similar result. After the removal of borosilicate glass (BSG) and boron-rich layer (BRL), the
effective lifetime reached as high as 276us.

Plane-Wave Propagation in Extreme Magnetoelectric (EME) Media

description: The extreme magnetoelectric medium (EME medium) is defined in terms of two medium dyadics, $α$, producing electric polarization by the magnetic field and $β$, producing magnetic polarization by the electric field. Plane-wave propagation of time-harmonic fields of fixed finite frequency in the EME medium is studied. It is shown that (if $ω\neq 0$) the dispersion equation has a cubic and homogeneous form, whence the wave vector $k$ is either zero or has arbitrary magnitude. In many cases there is no dispersion equation ("NDE medium") to restrict the wave vector in an EME medium. Attention is paid to the case where the two medium dyadics have the same set of eigenvectors. In such a case the $k$ vector is restricted to three eigenplanes defined by the medium dyadics. The emergence of such a result is demonstrated by considering a more regular medium, and taking the limit of zero permittivity and permeability. The special case of uniaxial EME medium is studied in detail. It is shown that an interface of a uniaxial EME medium appears as a DB boundary when the axis of the medium is normal to the interface. More in general, EME media display interesting wave effects that can potentially be realized through metasurface engineering.

description: The submitted work deals with the methods for manufacturing and analysis of contacts on crystalline
silicon solar cells. It is focused on selective processes for the production of solar cells metal contacts. The masking
feature of silicon nitride is used for selective silicon etching, selective phosphorus diffusion and selective electro-less
nickel deposition. Properties of metal contacts precursors are investigated using optical microscopy and their
electrical properties using methods based on a four-point probe method. Results are used for the manufacturing of
silicon, solar cell with an innovative type of the structure of the front side metallization: chemical nickel, conductive
adhesive and copper wire. This approach allows to reduce shading of the front area of PV cells with the ability to
avoid usage of busbars. The another advantage of this approach is in replacement of costly silver in at least 2/3 cross
section of the front side metallization. Selective ablation of silicon nitride layer was conducted by means of IR and
green laser beam.
