description: We explore the formation of massive high-redshift Population III (Pop III) galaxies through photoionization feedback. We consider dark matter halos formed from progenitors that have undergone no star formation as a result of early reionization and photoevaporation caused by a nearby galaxy. Once such a halo reaches $\approx 10^9~M_\odot$, corresponding to the Jeans mass of the photoheated intergalactic medium (IGM) at $z\approx 7$, pristine gas is able to collapse into the halo, potentially producing a massive Pop III starburst. We suggest that this scenario may explain the recent observation of strong He II 1640~Å~line emission in CR7, which is consistent with $\sim 10^7~M_\odot$ of young Pop III stars. Such a large mass of Pop III stars is unlikely without the photoionization feedback scenario, because star formation is expected to inject metals into halos above the atomic cooling threshold ($\sim 10^8~M_\odot$ at $z \approx 7$). We use merger trees to analytically estimate the abundance of observable Pop III galaxies formed through this channel, and find a number density of $\approx 10^{-7}~{\rm Mpc^{-3}}$ at $z=6.6$ (the redshift of CR7). This is approximately a factor of ten lower than the density of Ly$α$ emitters as bright as CR7.

description: Shunts are numerous defects on thin film modules and can be caused for instance by an interruption of different
laser scribing processes during the manufacturing procedure. These shunts have a negative effect on the module
performance. For this reason, the Solar Technology Lab investigated the detection of shunts on micromorph (μm)
thin film modules manufactured by Bosch Solar in mass production for 1.4 m² large-area μm-Si modules. Shunts
induced by laser scribing are classified and described in their behavior. High-resolution electroluminescence (EL)
measurements combined with thermographic (IR) images inspired new questions about shunt behavior. This project
will help to clarify how shunts influence module performance and the involved parameters. It is now possible to
identify the kind of shunts on μm-Si thin film modules by merely analyzing the corresponding EL and IR images.
Such information is a precondition for investigating the influence of shunts on the module voltage and current.
Additionally, the influence of shunt density and distribution between the cells was analyzed on μm-Si thin film
modules that were specifically designed for this project by Bosch Solar. The module performance is not only
influenced by the actual quantity of shunts caused by interruptions in the laser scribes; the shunt density on a
module area and the distance between them has an additional effect on the power loss. Further investigations on μm
thin film modules with a designated amount of shunts and shunt density providing a deeper understanding about
their behavior and influence will be presented in this publication.

description: Motivated by a recent experiment of J.~Steinhauer, we reconsider the spectrum and the correlations of the phonons spontaneously emitted in stationary transonic flows. The latter are described by "waterfall" configurations which form a one-parameter family of stable flows. For parameters close to their experimental values, in spite of high gradients near the sonic horizon, the spectrum is accurately planckian in the relevant frequency domain, where the temperature differs from the relativistic prediction by less than $10 \%$. We then study the density correlations across the horizon and the non-separable character of the final state. We show that the relativistic expressions provide accurate approximations when the initial temperature is not too high. We also show that the phases of the scattering coefficients introduce a finite shift of the location of the correlations which was so far overlooked. This shift is due to the asymmetry of the flow across the horizon, and persists in the dispersion-less regime. Finally we show how the formation of the sonic horizon modifies both local and non-local density correlations.

See Hellmayr, 1938: 130, Paynter, 1970b: 164, and Dickinson, 2003: 796. HOLOTYPE: AMNH 516980, adult male, collected on Darwin (5 Culpepper) Island, 01.39S, 92.00W (Paynter, 1993), Galapagos Islands, Ecuador, on 27 July 1897, by Rollo Beck on the Webster-Harris Expedition (no. 157). From the Rothschild Collection. COMMENTS: No type was designated in the text of the original description, where measurements were given for four males and one female, but Beck’s specimen no. 157 is designated as the type of Geospiza darwini in the same publication on pl. VI, fig. 21, a drawing of the beak of the holotype. Reference to this plate is also written on the reverse of the Rothschild type label of AMNH 516980. Paratypes in AMNH, all collected on Darwin Island on the Webster-Harris Expedition in 1897, are: AMNH 516977, adult male, 26 July, by Harris; AMNH 516978, adult male, 26 July, by Hull; AMNH 516979, immature male, 27 July, by Drowne; AMNH 516785, adult male, 27 July, by Beck, the last three now identified as magnirostris. I think that Rothschild and Hartert considered the immature bird to be a female. The right wing of that specimen is missing feathers, but the measurement of the left wing is 84 mm, the measurement given for the female.

description: Turbulent dynamo field amplification has often been invoked to explain the strong field strengths in thin rims in supernova shocks ($\sim 100 \, μ$G) and in radio relics in galaxy clusters ($\sim μ$G). We present high resolution MHD simulations of the interaction between pre-shock turbulence, clumping and shocks, to quantify the conditions under which turbulent dynamo amplification can be significant. We demonstrate numerically converged field amplification which scales with Alfvén Mach number, $B/B_0 \propto {\mathcal M}_{\rm A}$, up to ${\mathcal M}_{\rm A} \sim 150$. This implies that the post-shock field strength is relatively independent of the seed field. Amplification is dominated by compression at low ${\mathcal M}_{\rm A}$, and stretching (turbulent amplification) at high ${\mathcal M}_{\rm A}$. For high $\mathcal{M}_{\rm A}$, the $B$-field grows exponentially and saturates at equipartition with turbulence, while the vorticity jumps sharply at the shock and subsequently decays; the resulting field is orientated predominately along the shock normal (an effect only apparent in 3D and not 2D). This agrees with the radial field bias seen in supernova remnants. By contrast, for low $\mathcal{M}_{\rm A}$, field amplification is mostly compressional, relatively modest, and results in a predominantly perpendicular field. The latter is consistent with the polarization seen in radio relics. Our results are relatively robust to the assumed level of gas clumping. Our results imply that the turbulent dynamo may be important for supernovae, but is only consistent with the field strength, and not geometry, for cluster radio relics. For the latter, this implies strong pre-existing $B$-fields in the ambient cluster outskirts.

description: A sophisticated light management is important for the overall performance of thin-film solar cells
based on amorphous (a-Si:H) and microcrystalline (μc-Si:H) silicon. Thus, an important issue in designing high
efficient solar cells is to optimize both light in-coupling and light trapping by improving the topology of the nanotextured
interfaces. It is well known that a rough transparent conductive oxide (TCO) leads to an increase of the
quantum efficiency (QE) and short-circuit current density (JSC). Improving the light trapping in a solar cell by
manufacturing various TCO structures is a very complex process. Simulations are an inexpensive way to compare
different structures without manufacturing a whole solar cell. Furthermore, thin-film solar cells are usually integrated
in building facades, which leads to oblique incident sunlight of varying angles over the course of the day. To this end,
a simulation tool for solving Maxwell’s equations based on the finite difference time domain (FDTD) method and the
finite integration technique (FIT) is developed to calculate the efficiency of thin-film solar cells for oblique incident
light. Parallel computations on high performance computers (HPC) are needed to meet the large computational
requirements.

description: MgO thin films were deposited on the glass substrate prior to the ZnO:Al (AZO) deposition for antireflection
layer at glass/ZnO:Al interface. X-ray diffraction studies showed that AZO film grown on MgO precursor
had a decreased crystallinity compared with one grown on the glass. However, the surface textured AZO film grown
on MgO exhibited high light trapping property. The average haze was increased from 15 to 51 % in the visible region
and it was enhanced from 7 to 22% in the NIR region. The highly compact AZO film was decreased in density and
etching process was more feasible in MgO/AZO bilayer. The AFM studies indicated that the rms surface roughness
was increased from 83 to 266 nm by employing MgO precursor. The microcrystalline silicon solar cell with
MgO/AZO bilayer TCO showed the improvement of EQE by decreasing optical reflectance. By applying the AR
layers consisted of MgO and TiO2:Nb, the short circuit current was increased from 21.2 to 26.3 mA/cm2. The
efficiency of solar cells was improved from 5.2 to 8.81 %.

description: Reference solar cells are the fundamental instruments for the correct adjustment of the irradiance of
solar simulators for solar cell testing and PV performance measurements. Besides the flasher-based simulators, a
typical steady-state simulator works with a light beam conditioned by a series of optical components, which finally
reach the (reference) solar cell package and the solar cell itself. Here, multiple reflections can occur within a solar
simulator between the components, especially between the last optical component of the simulator and the device
under test. Our investigations on the accuracy of the solar simulator intensity adjustments have led to the observation
of a second perturbing error source beside that of multiple reflections. The reflected light beam of the reference cell
reaches the solar simulator’s internal sensor, which gives feedback to the lamp regulator. In this way, the original
idea of reducing the xenon lamp fluctuations is a source of a systematic error.

(ZnO:B) thin films and ZnO:B on tungsten doped indium oxide (In2O3:WO3, IWO) coated glass (glass/IWO/ZnO:B)
were investigated in this work. ZnO:B thin films were directly grown via low pressure metal organic chemical vapor
deposition (LP-MOCVD) at low temperature of ~150 . The IWO thin films were deposited by the reactive electron
beam vapor technique. High purity diethylzinc (DEZn) and H2O were used as source materials, and diborane (B2H6)
was used as an n-type dopant gas. The gradual doping growth (GDG) techniques are applied in LP-MOCVD ZnO:B
thin films process. The IWO/ZnO:B thin films exhibit rough pyramid-like surface morphology with high total
transparencies and excellent electrical properties as well as improved diffuse transmittance. These ZnO:B and
IWO/ZnO:B thin films are promising TCO layers applied as substrates for silicon-based thin film solar cells.

description: Dc magnetron sputter deposited indium tin oxide (ITO) films for silicon based hetero-junction solar
cell application are studied. The films show suitable properties with transmittance as high as ~94% and resistivity as
low as 2.2 x 10-4 Ω cm. Oxygen is used as reactive gas and the sputtering gas is argon. The depositions are done at
room temperature, and subsequent annealing is carried out on a hot-plate at different temperatures (250 °C, 300°C
and 350°C) in air atmosphere. The O2/(Ar+O2) flow vol% into the sputtering chamber is varied from 0 to 25. An
improvement in optical and electrical properties is demonstrated when the films are annealed. The structure of the asdeposited
films is shown to be dependent on the oxygen present during sputtering. When no oxygen is added, the
films exhibit an amorphous structure. When oxygen flow is introduced, the XRD patterns indicate crystalline films.
Besides, high flows of oxygen results in higher resistivity of the films. The resistivity can be considerably reduced by
a post-deposition heat treatment.

description: The p-type Si layer in n-i-p a-Si and μc-Si solar cells on foil has several important requirements with
respect to conductivity and optical transmission. We control the optical band gap and activation energy of p-a-SiC by
varying the B2H6 and CH4 flows in the process chamber. Modelling shows that the optimum efficiency in n-i-p solar
cells is obtained when the p-a-SiC band gap is just above the band gap of the absorber layer. We have assessed the
potential of core-loss electron energy-loss spectroscopy (EELS) for detecting B and C and of low-loss EELS, in a
spatially resolved manner, as probe of local variations in bulk plasmon energy. EELS in the transmission electron
microscope (TEM) combines the necessary spatial resolution to investigate the boundary between p-a-SiC and i-a-Si
with sufficient sensitivity to the boron content.

description: An inconsistent knowledge base can be abstracted as a set of arguments and a defeat relation among them. There can be more than one consistent way to evaluate such an argumentation graph. Collective argument evaluation is the problem of aggregating the opinions of multiple agents on how a given set of arguments should be evaluated. It is crucial not only to ensure that the outcome is logically consistent, but also satisfies measures of social optimality and immunity to strategic manipulation. This is because agents have their individual preferences about what the outcome ought to be. In the current paper, we analyze three previously introduced argument-based aggregation operators with respect to Pareto optimality and strategy proofness under different general classes of agent preferences. We highlight fundamental trade-offs between strategic manipulability and social optimality on one hand, and classical logical criteria on the other. Our results motivate further investigation into the relationship between social choice and argumentation theory. The results are also relevant for choosing an appropriate aggregation operator given the criteria that are considered more important, as well as the nature of agents' preferences.

description: Flexible amorphous solar cell on polyimide allows to combine both roll-to-roll continuous fabrication,
and monolithic series connection, and they also offer specific advantages concerning handling (cleaning) and
application (weight, flexibility). Laser scribing and other processes are used to make monolithic module, but there are
few reports about laser scribing of flexible amorphous silicon solar cell on polyimide. This paper is focused on a
study of laser scribing of flexible amorphous silicon solar cell on polyimide. The optical characters about the
materials of Ag/ZnO, amorphous silicon, ITO are analysised. Multi-kHz Q-switched solid-state nanosecond lasers
with wavelengths of 1064nm and 532nm were used in this study. Detailed laser scribing parameters such as repetition
rate of the laser pulses, scanning speed of the sample and laser beam, individual pulse energy, laser wavelength are
examined. Characteristics of the scribing conditions are evaluated in terms of optical microscopy, confocal
microscopy, et al. The electrical validation is also implemented. The experiments show that the laser scribings meet
the requirements of flexible amorphous silicon solar cell on polyimide.

design of HIT device, the efficiency was increased from 3.67% to 8.05%. These results indicate that the surface
properties of these HIT devices were well controlled and exhibit a solar cell performance well.

description: The effect of very small disilane addition in silane-hydrogen mixtures on the growth rate of silicon thin films is investigated. Different ways of gas introduction into the plasma zone were tested including single gas entrance configuration as well as two different showerhead designs. Variation of flow and mixing conditions were critical for the effect of disilane addition on the electrical properties of the discharge and the film growth rate. Electrical measurements showed that the power density of the discharge is slightly affected by the disilane addition but affects much stronger the phase impedance leading to more resistive plasmas. The way the growth rate is influenced by the disilane addition depends on the RF electrode design and the proper choice of the process parameters.

description: Moser Baer Technologies have developed a glass superstrate with nano-imprinted periodic
texture which has been specifically designed for optimal light-trapping for the micromorph (a-Si:H/ μc-Si:H) tandem
device. Only a thin AZO layer of ≤ 400 nm is necessary on this pre-textured superstrate which can be optimized for
optimal transmission and sheet resistance properties independently of the substrate morphology. The periodic
textured superstrate, which has been optimized by e.g. varying the texture period, has a superior light trapping that
outperforms Asahi-U with a 24% JSC increase for a 1.2 μm μc-Si:H bottom cell and an overall tandem current
increase of 22%. By careful optimization of the texture shape, height and duty cycle we realized a uniform texture
which demonstrates both a good light trapping (JSC) while maintaining a high junction quality (VOC and FF) resulting
in an efficiency increase of 15% which is maintained after light induced degradation. Scalability up to Gen2
(470x370 mm2) size and compatibility of this technology with existing module production techniques like laserscribing
have been demonstrated. Sub-assemblies of glass with nano-imprint layer and ZnO:Al surpass IEC test
levels for UV, damp heat, thermal cycling, humidity freeze and combined high stress levels.

description: Improvement in the layer quality is one of the main topics in increasing efficiency of thin film silicon
solar cells. Therefore, process control is discussed in order to reduce effects of initial transition states. In this work we
present our progress in installing real-time process control into an existing deposition system. By monitoring different
depositions with optical emission spectroscopy (OES) it becomes clear that optical emission signals are sensitive to
SiH4 flow, power and pressure changes. H/SiH and H/SiH intensity ratios correlate with Raman crystallinity of the
deposited layers, when SiH4 flow is changed.
Deposition processes can be stabilized by using real-time process control, where setpoints and actual values of mass
flow control are modified depending on OES signals. Hence, the H/SiH is stable during the complete deposition.

description: We show that applying the Bailey lemma to elliptic hypergeometric integrals on the $A_n$ root system leads to a large web of dualities for $\mathcal{N} = 1$ supersymmetric linear quiver theories. The superconformal index of Seiberg's SQCD with $SU(N_c)$ gauge group and $SU(N_f)\times SU(N_f)\times U(1)$ flavour symmetry is equal to that of $N_f-N_c-1$ distinct linear quivers. Seiberg duality further enlarges this web by adding new quivers. In particular, both interacting electric and magnetic theories with arbitrary $N_c$ and $N_f$ can be constructed by quivering an $s$-confining theory with $N_f=N_c+1$.

description: Improved P2 and P3 scribing of thin film a-Si and CdTe solar cells are demonstrated using a 532 nm
picosecond fiber laser with a square flat-top shaped beam profile at the work surface. The shaped beam profile
optimizes the application of the available pulse energy and results in significantly faster scribe rates than achievable
with Gaussian profiles. The uniform application of the fluence also improves scribe quality. The sidewalls are
extremely straight and sharp and the absorber material is completely and uniformly removed from the underlying
TCO with no damage to the TCO itself. Defects like cracking of the substrate or absorber edges, or peeling of the
metal contacts are eliminated by the sharp profile edges of the flat-top beam and single pulse material removal.

description: This paper is about skew monoidal tensored V-categories (= skew monoidal hommed V-actegories) and their categories of modules. A module over is an algebra for the monad T = R * _ on M. We study in detail the skew monoidal structure of M^T and construct a skew monoidal forgetful functor from M^T to the category of E-objects in M where E=M(R,R) is the endomorphism monoid of the unit object R. Then we give conditions for the forgetful functor to be strong monoidal and for the category M^T of modules to be monoidal. In formulating these conditions a notion of `self-cocomplete' subcategories of presheaves appears to be useful which provides also some insight into the problem of monoidality of the skew monoidal structures found by Altenkirch, Chapman and Uustalu on functor categories [C,M].

description: First we investigate the evolutions of the radius function and its gradient along the volume-preserving mean curvature flow starting from a tube (of nonconstant radius) over a compact closed domain of a reflective submanifold in a symmetric space under certain condition for the radius function. Next, we prove that the tubeness is preserved along the flow in the case where the ambient space is a rank one symmetric space of non-compact type (other than a (real) hyperbolic space) and the reflective submanifold is an invariant submanifold and the radius function of the initial tube is radial. Furthermore, in this case, we prove that the flow reaches to the invariant submanifold or it exists in infinite time and converges to another tube of constant mean curvature over the invariant submanifold in the $C^{\infty}$-topology in infinite time.

description: The fast market growth during the recent years led to huge amounts of production capacities and a large
variety of module types. The increasing need for cost reductions obliges the manufacturers to maximize production and
module efficiencies. Electroluminescence investigation is a powerful tool to reveal failures of thin film photovoltaic
modules during the production stage and within test sequences. We use it to identify failures after reliability tests
included in the IEC 61646 or beyond such as bias damp heat assessments. In an earlier stage, the manufacturer could use
it to sort and optimize his products directly after frontend production. The results presented here aim to pave the way for
such an inline electroluminescence analysis.
In this paper we also present spectral analysis of electroluminescence signals to simplify the choice of cameras and filters
as a set-up for an EL testing station. Furthermore, we compiled a failure catalogue for all thin-film modules, applying
electroluminescence. We developed a brightness-evaluation sheet to describe the analogies between power losses and
lowering of brightness. Finally, we investigated the effect of the shunt resistance of CIGS modules on their weak light
behavior.
Nematic quantum phase transition of composite Fermi liquids in half-filled Landau levels and their geometric response

description: We present a theory of the isotropic-nematic quantum phase transition in the composite Fermi liquid arising in half-filled Landau levels. We show that the quantum phase transition between the isotropic and the nematic phase is triggered by an attractive quadrupolar interaction between electrons, as in the case of conventional Fermi liquids. We derive the theory of the nematic state and of the phase transition. This theory is based on the flux attachment procedure which maps an electron liquid in half-filled Landau levels into the composite Fermi liquid close to a nematic transition. We show that the local fluctuations of the nematic order parameters act as an effective dynamical metric interplaying with the underlying Chern-Simons gauge fields associated with the flux attachment. Both the fluctuations of the Chern-Simons gauge field and the nematic order parameter can destroy the composite fermion quasiparticles and drive the system into a non-Fermi liquid state. The effective field theory for the isotropic-nematic phase transition has $z = 3$ dynamical exponent due to Landau damping effects. We show that there is a Berry phase type term which governs the effective dynamics of the nematic order parameter fluctuations, which can be interpreted as a non-universal "Hall viscosity" of the dynamical metric. We show that the effective field theory has a Wen-Zee-type term. Both terms originate from the time-reversal breaking fluctuation of the Chern-Simons gauge fields. We present a perturbative computation of the Hall viscosity and also show that this term is also obtained by a Ward identity. We show that the disclination of the nematic fluid, carries an electric charge. We show that a resonance observed in radio-frequency conductivity experiments can be interpreted as a Goldstone nematic mode gapped by lattice effects.

description: Terahertz (THz) near-field imaging is a flourishing discipline [1], with applications from fundamental studies of beam propagation [2,3] to the characterisation of metameterials [4,5] and waveguides [6,7]. Beating the diffraction limit typically involves rastering structures or detectors with length scale shorter than the radiation wavelength; in the THz domain this has been achieved using a number of techniques including scattering tips [8,9] and apertures [10]. Alternatively, mapping THz fields onto an optical wavelength and imaging the visible light removes the requirement for scanning a local probe, speeding up image collection times [11,12]. Here we report THz to optical conversion using a gas of highly excited `Rydberg' atoms. By collecting THz-induced optical fluorescence we demonstrate a real-time image of a THz standing wave and we use well-known atomic properties to calibrate the THz field strength. The mono-atomic gas does not distort the THz field and offers the potential to immerse structures within the THz-to-optical conversion medium.
