description: In order to quantify the error budget in the measured probability distribution functions of cell densities, the two-point statistics of cosmic densities in concentric spheres is investigated. Bias functions are introduced as the ratio of their two-point correlation function to the two-point correlation of the underlying dark matter distribution. They describe how cell densities are spatially correlated. They are computed here via the so-called large deviation principle in the quasi-linear regime. Their large-separation limit is presented and successfully compared to simulations for density and density slopes: this regime is shown to be rapidly reached allowing to get sub-percent precision for a wide range of densities and variances. The corresponding asymptotic limit provides an estimate of the cosmic variance of standard concentric cell statistics applied to finite surveys. More generally, no assumption on the separation is required for some specific moments of the two-point statistics, for instance when predicting the generating function of cumulants containing any powers of concentric densities in one location and one power of density at some arbitrary distance from the rest. This exact "one external leg" cumulant generating function is used in particular to probe the rate of convergence of the large-separation approximation.

description: Copper light-induced plating onto the surface of existing screen-printed silver contacts of industrial
Silicon solar cells was studied. Electrolyte and cell-in-electrolyte systems were analyzed to determine the optimal
plating conditions. Two methods of protection of a cell rear side from dissolution (by insulating and by applying
electrical potential) are compared. It was found that the parasite cells are created in the plating bath due to the
difference of the redox potentials of silver, copper and aluminum. Previously reported equilibrium conditions for
terminal and anode – rear side voltage must be modified to compensate the parasite cell current. The solar cell
efficiency gain is found to be a nonmonotonic function of deposition rate and duration. Absolute solar cell efficiency
was improved by 1,53%.

description: Thin film solar cells based on Copper Indium Gallium Selenide (CIGS) are a promising candidate for
low cost / Wp manufacturing due to the low material consumption combined with rather high cell efficiencies. In the
present paper we will outline the key factors for a profitable manufacturing managed by means of Key Performance
Indicators (KPI). Finally we will present a Process Control and Optimization Application (PCOA) that is capable of
measuring and controlling these KPIs. This application secures that all the complex interrelations between KPI
drivers are transparent and visible and in turn a matter of continuous optimization.

description: Screen printed silver nanoparticles were investigated as an alternative contact material for thin film
solar cells. Front contact grids based on silver pastes were screen printed on smooth and rough aluminum doped zincoxide
and indium tin oxide films. The size of the silver particles in the silver paste was varied from 5 nm to several
micrometers and the influence of the annealing conditions on the specific contact resistance was studied. The
formation of electrical contacts on transparent conductive oxides (TCO) depends on the surface roughness of the
TCO films. Our experiments suggest that an increasing roughness leads to an increasing specific contact resistance.
The specific contact resistance of silver nanoparticle pastes does not seem to suffer as much, when printed on rough
surfaces.

description: The X/Ka-band (8.4/32 GHz) Celestial Reference Frame became one component of the ICRF-3 in 2018. In the six years since, the X/Ka data set has increased by a factor of two as well as adding the much needed north-south geometry from Japan to Australia.  Median formal precision is now better than 100 micro-arseconds. The accuracy of the frame is limited by systematic errors larger than the formal precision. The limited network geometry allows for geometric distortions—most notably quadrupole 2,0 distortions. This paper will compare the use of two data weighting  methods to account for the dominant noise from wet tropospheric fluctuations and the resulting impact on systematic frame distortions:1) white noise weighting2) elevation dependent white noise

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 3255-3260
description: Discrepancies have been found between the models used in PV simulation programs and outdoor measurements.
3rd party PV kWh/kWp measurement reports sometimes show insufficient data to understand their results and
often make incorrect assumptions as to the cause and importance of the results (which often differ in ranking).
Suggestions are made on how to improve the modelling of PV arrays and comparisons with measured data.
A new “Loss Factors Model” has been developed with Oerlikon Solar which can model outdoor IV curves for
different PV technologies at different sites under different weather conditions.
University museums and collections in Mexico

Subjects: University Heritage

description: Through five questions that connect the university heritage and the museums, the author points out the convenience of thinking the university museums as spaces of interaction. This patrimonial perspective can increase the social values of the museums and the universities as well. To achieve this goal, it is important to generate interaudiences interested in the appreciation and protection of the musealized heritage and to assume the glocal dimension. These new paradigms can help to consolidate a university museology.

description: Laser cutting experiments of ZnO:Al TCO layers were carried out in wide range of parameters (1-
25cm/s speed, 1-10kHz pulse frequency and 200-5800mW power) but the pulse energy was kept in a narrow range.
Optical microscopy of the cuts revealed that there is a critical power for the full ablation of the layer. A parameter
range for optimal cutting as a function of the layer thickness is established. Ellipsometry measurements were
evaluated by a Cauchy model using a double-layer optical model and resulting in a reliable thickness measurement.
Criteria for the transparent conductive character of the layer are also established. These results offer a feasible in-line
technique for setting proper cutting parameters of the TCO layer.

description: We compute the transport coefficients, namely, the coefficients of shear and bulk viscosity as well as thermal conductivity for hot and dense quark matter. The calculations are performed within the Nambu- Jona Lasinio (NJL) model. The estimation of the transport coefficients is made using a quasiparticle approach of solving the Boltzmann kinetic equation within the relaxation time approximation. The transition rates are calculated in a manifestly covariant manner to estimate the thermal-averaged cross sections for quark-quark and quark-antiquark scattering. The calculations are performed for finite chemical potential also. Within the parameters of the model, the ratio of shear viscosity to entropy density has a minimum at the Mott transition temperature. At vanishing chemical potential, the ratio of bulk viscosity to entropy density, on the other hand, decreases with temperature with a sharp decrease near the critical temperature, and vanishes beyond it. At finite chemical potential, however, it increases slowly with temperature beyond the Mott temperature. The coefficient of thermal conductivity also shows a minimum at the critical temperature.

description: Intelligent reflecting surface (IRS) has recently received much attention from the research community due to its potential to achieve high spectral and power efficiency cost-effectively. In addition to traditional cellular networks, the use of IRS in vehicular networks is also considered. Prior works on IRS-aided vehicle-to-everything communications focus on deploying reflection surfaces on the facades of buildings along the road for sidelink performance enhancement. This paper goes beyond the state of the art by presenting a novel paradigm coined Intelligent Reflecting Vehicle Surface (IRVS). It embeds a massive number of reflection elements on vehicles' surfaces to aid moving vehicular networks in military and emergency communications. We propose an alternative optimization method to optimize jointly active beamforming at the base station and passive reflection across multiple randomly-distributed vehicle surfaces. Performance evaluation in terms of sum spectral efficiency under continuous, discrete, and random phase shifts is conducted. Numerical results reveal that IRVS can substantially improve the capacity of a moving vehicular network.

description: For several reasons, amorphous silicon is expected to be the preferred technology for hot climates: low temperature
coefficients for maximum power, prevalence of annealing effect over light induced degradation, better matching of
the solar spectrum due to air mass effects and smaller fraction of diffused light in comparison to direct one. An
empirical method of the energy yield prediction of the amorphous silicon technology using full time series of
irradiance and temperature for different geographical locations was developed, validated for a roof integrated PV
system and a free mounted triple junction amorphous silicon module and simulated for different sites in Europe and
Africa.

description: The present paper deals with diagnostics of crystalline silicon solar cells with structures prepared by
application of laser technologies. We used noise diagnostic methods, study of local optical properties in the far-field
and near-field microscopy. It was found out that laser-prepared structures intersecting the pn junction exhibit ohmic
behaviour, causing changes in the electrical parameters of cells and deteriorate locally their properties, but do not
cause origin of defects leading to local breakdowns of reverse-biased solar cells pn junctions. Models describing the
electrical behaviour of laser-prepared structures were found and some of their parameters were determined based on
submitted studies. The influence of parallel resistance caused by edges conductivity on measured characteristics was
discussed. The obtained results will be used in search of procedures for solar cells edges processing applicable in
manufacturing.

Synchronizing quantum and classical clocks made of quantum particles

description: We demonstrate that the quantum corrections to the classical arrival time for a quantum object in a potential free region of space, as computed by Galapon [Phys. Rev. A {\bf 80}, 030102(R) (2009)], can be eliminated up to a given order of $\hbar$ by choosing an appropriate position-dependent phase for the object's wavefunction. This then implies that we can make the quantum arrival time of the object as close as possible to its corresponding classical arrival time, allowing us to synchronize a classical and quantum clock which tells time using the classical and quantum arrival time of the object, respectively. We provide an example for synchronizing such a clock by making use of a quantum object with a position-dependent phase imprinted on the object's initial wavefunction with the use of an impulsive potential.

Environmental Profile of PV Mass Production: Globalization

Environmental Impacts, Recycling and Waste Management

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 3080-3083
description: The globalization of the production of PV requires an analysis of the environmental impact which takes
country specific production processes into account. The country electricity mix influences the primary energy needed
and CO2-equivalents emitted per kWh produced. The electricity mix used for the production of poly-silicon is often
different from the country mix but also considered confidential in many cases. For the production of poly-silicon
several manufacturers use hydropower or Combined Heat&Power (CHP)/Cogeneration but exact data are missing.
As a result energy payback time and carbon footprint for equal factories differ based on electricity mix used. In
addition to this difference due to production location the irradiation on the solar panel depends on installation
location.
For commercial roof-top flat plate PV systems, the energy payback time and carbon footprint vary considerably for
silicon based modules based on the actual country mix, with the low end of the range with poly-Si from hydropower
and wafer/cell/module from UCTE electricity. The energy payback time and carbon footprint of CdTe thin film PV
technology is less sensitive to country energy mix due to the lower electricity consumption of CdTe PV module
production compared to other PV technologies For this analysis, all systems were assumed to be installed in Southern
Europe (1700 kWh/m2.year). For commercial roof-top flat plate PV systems with poly-Si from hydropower and
wafer/cell/module from UCTE electricity, installed in Southern Europe (1700 kWh/m2.year):
• Energy payback time ~0.8-1.7 years,
• Carbon footprint ~19-34 g CO2-eq/kWh.
Concentrator PV modules use a different part of the irradiation compared to flat-plat PV modules and can only be
compared for a certain installation location. Two commercial CPV systems assumed to be installed in Catania (Sicily)
have energy payback times of 0.7 and 1.5 years at DNI of 1794 kWh/m2.year (Catania, Sicily) on a 2-axis tracker.
The global irradiation on optimally-inclined flate plate module on this location is 1925 kWh/m2.year.

description: We study the dynamics of the positive solutions of a second-order, Ricker-type exponential difference equation with periodic parameters. We find that qualitatively different dynamics occur depending on whether the period p of the main parameter is odd or even. If p is odd then periodic and non-periodic solutions may coexist (with different initial values) if the amplitude of the periodic parameter is allowed to vary over a sufficiently large range. But if p is even then all solutions converge to an asymptotically stable limit cycle of period p if either all the odd-indexed or all the even-indexed terms of the periodic parameter are less than 2, and the sum of the even terms does not equal the sum of the odd terms. The key idea in our analysis is a semiconjugate factorization of the above equation into a triangular system of two first-order equations.

description: Monolithically integrated Cu(In,Ga)Se2-based (CIGS) modules can be manufactured on polyimide
films. However, there are significant technical challenges involved:
i) The standard “co-monolithic” patterning steps represent interruptions between deposition processing steps. A rollto-
roll production line would profit from the continuous deposition of sequential layers without interruptions.
ii) Warping of the polymer substrate during the CIGS deposition process is already an issue due to different
expansion coefficients of the substrate and layers. The scribed back contact layer (P1) is an additional warping factor.
In order to avoid these disadvantages, we have developed an interconnection method which defers the structuring and
wiring until after the whole stack deposition has been completed (post-monolithic interconnection).
In this contribution, we demonstrate the feasibility of the post-monolithic approach with first results on glass
substrates. The width of the patterned region was up to 1700 μm (including bus-bar), about four times larger than for
“standard” co-monolithically integrated modules. Without patterning, the single cells of the module had active-area
(aperture-area) efficiencies (AM1.5) of 9.7 % (6.1 %) to 11.3 % (7.1 %). After post-monolithic interconnection a
module-efficiency of 9.6 % (6.1 %) was achieved. It is expected that the active area lost due to patterning can be
further reduced by shrinking the patterning width to about 500 μm, a value comparable to co-monolithically
integrated modules. Despite a slightly larger area loss, the post-monolithic interconnection approach has the
advantage of separating the layer deposition processes from the cell connection processes.
We will discuss different approaches for the post-monolithic cell interconnection with respect to the roll-to-roll
production of CIGS on 25-μm-thin polyimide films.

description: Recent advances in in-situ process control leads us to revisit the multi-stage Cu-poor growth of
CuInS2. A combination of laser light scattering and pyrometry allow the precise monitoring of the excess Cu2-xS
phase formation and consumption during the process. Of particular interest is the control and characterization of the
CuIn5S8 fraction. The evolution of the composition and microstructure of slightly copper-rich and slightly copperpoor
material is evaluated using x-ray fluorescence, x-ray diffraction, and scanning electron microscopy. In the Cupoor
film, a mixture of chalcopyrite CuInS2 and thiospinel CuIn5S8 are observed, associated with significant changes
in surface and cross sectional morphology compared to the Cu-rich sample. The CuIn5S8 concentration is pronounced
at the surface, leading to platelet structures. These films are fabricated into solar cells and characterized by currentvoltage
and quantum efficiency measurements. Intentional sodium doping from a NaF precursor improves the open
circuit-voltage, fill factor, and efficiency significantly. A cell based on a slightly Cu-poor CuInS2 film shows a 1-sun
conversion efficiency of 9.6% (VOC=715mV, JSC=22.7 mA/cm2, fill factor=59.2%) despite the presence of CuIn5S8.

description: Red illumination of the reverse-biased device (ROB) causes persistent increase of the capacitance of
CIGS-based solar cells. ROB effect can only be explained in terms of relaxing defects, undergoing shallow-deep
transition. According to theoretical calculations, IIICu defect is a probable candidate. We demonstrate here that ROB
effect is present in all CIGS chalcopyrite compounds including wide band gap CuGaSe2 and CuInS2 and show that
photovoltaic parameters of the devices depend on the charge state of the antisite defect. The role of the blue part of
the illumination spectrum for establishing favorable charge distribution is demonstrated. The relation between the
Fermi-level position at interface and the antisite influence on the photovoltaic parameters is discussed.

description: The carrier lifetime in oxygen-rich boron-doped crystalline silicon degrades under illumination at room
temperature, both in p- and n-type silicon. While this so-called light-induced degradation has been intensely studied
in p-type silicon, the data base on n-type silicon is still sparse. In this work, the defect generation in dopantcompensated
n-type silicon is investigated at different light intensities, revealing a considerable increase of the defect
generation rate with increasing light intensity. Based on this finding, we propose that the defect generation rate
constant is proportional to the square of the hole concentration. Since holes are minority carriers in n-type silicon,
their concentration depends on the carrier lifetime and the generation rate of excess carriers. The lifetime in turn
depends on the amount of recombination active defects, which increases during the course of degradation. The result
is a complex time dependence of the effective defect concentration. Simulations based on this model yield excellent
agreement with the experimental data. In addition, by comparison with existing data of the rate coefficients in p-type
silicon, the defect is identified as the fast forming recombination-center observed in p-Si.

description: Ultrasonic spray pyrolysis (USP) is a low-cost, non-vacuum and in-line compatible deposition method for alternative
buffer layers such as indium sulfide in CIGS based thin-film solar cells. Solution precursors are ultrasonically
atomized and transferred to a heated substrate. On the substrate’s surface a thin layer is formed by a chemical
reaction of the precursors. The layer formation is mainly influenced by the substrate temperature, the concentration of
the precursor solution, the solvent properties and droplet feed rate. We present a possible chemical reaction equation
and the mechanism for this reaction. CIGS based solar cells with USP-In2S3 buffer layer were fabricated and yielded
reproducible efficiencies of 13% and best cell efficiency of 13.4% without anti reflection coating.

description: This paper presents and compares the results of a pilot production of n+pn+ and n+pp+ silicon solar
cells. Processes were based on phosphorus or phosphorus/aluminum diffusion and screen-printing of metal grid. Each
processing step of both fabrication sequences was optimized and more than 12.000 cells were manufactured. The
average efficiencies of 12.7% and 14.5% were obtained and best devices presented efficiencies of 13.4% and 16.1%,
for n+pn+ and n+pp+ structure, respectively. A production yield of around 86 % was found for both processes, but
n+pp+ cells presented higher dispersion in short-circuit current and consequently in efficiency.

description: We consider the problem of learning the underlying graph of an unknown Ising model on p spins from a collection of i.i.d. samples generated from the model. We suggest a new estimator that is computationally efficient and requires a number of samples that is near-optimal with respect to previously established information-theoretic lower-bound. Our statistical estimator has a physical interpretation in terms of "interaction screening". The estimator is consistent and is efficiently implemented using convex optimization. We prove that with appropriate regularization, the estimator recovers the underlying graph using a number of samples that is logarithmic in the system size p and exponential in the maximum coupling-intensity and maximum node-degree.

description: Photovoltaic (PV) generation is characterized by a low predictability, a high variability and a low
controllability, which may be critical for the large scale integration of PV generation into power systems.
Consequently, PV systems can be combined with energy storage devices in order to reduce these integration issues.
This paper presents the operational results obtained from the combination of a 18 kWp PV system combined with a
10 kVA – 100 kWh Vanadium RedOx flow energy storage system. The combined system has been operated in order
to respect grid integration constraints proposed by the French energy regulation authority. Two energy management
strategies are proposed and implemented. Both strategies lead to a reduction of fluctuations of PV generation, which
enable large scale integration of PV generation into electricity networks.

description: We analyze the superconformal index of the N=3 supersymmetric Z_k generalized orientifold theories recently proposed. In the large N limit we derive the index from the Kaluza-Klein modes in AdS_5 x S^5/Z_k, which are obtained from ones in AdS_5 x S^5 by a simple projection. For the ordinary Z_2 orientifold case the agreement with the gauge theory calculation is explicitly confirmed, and for Z_k with k > 2 we perform a few consistency checks with known results for N=3 theories. We also study finite N corrections by analyzing wrapped D3-branes and discrete torsions in the dual geometry.

description: An internally accomplished analysis has shown that arc fault detection offers the possibility to reduce the
risk of fire in 80% of all considered failure conditions. In 2011, a listed system-integrated PV AFCI for detecting series
arc faults will be demanded by the NEC Art. 690.11 certified to UL1699. Due to these facts, a strategy for reliably
detecting arc faults and simultaneously preventing the increase of Total Costs of Ownership (TCO) has to be developed.
In this regard, an inverter-integrated AFCI, protecting the entire PV array, is the preferable solution in comparison to
decentralized approaches. The main advantage is that already existing inverter components are suitable to fulfill
specifications demanded by the standards. Furthermore, an inverter-integrated solution does not lead to additional
costs for installation and maintenance. Besides the economic efficiency, this work can demonstrate that the inverterintegrated
AFCI reliably detects series arc faults in the main path of the PV array as well as in parallel paths with a
decreased sensitivity of measurement.

description: Gettering and passivation steps during solar cell processing influence the recombination activity of
grain boundaries in silicon wafers. The purpose of this work is to study the influence of different solar cell
processing steps on the recombination activity. Neighbouring wafers of intentionally contaminated multicrystalline
ingots were differently processed to solar cells or treated with single POCl3-diffusion, hydrogenation or temperature
steps. Therefore, the influence of these solar cell processing steps on recombination activity could be evaluated
individually by electron beam induced current (EBIC) measurements. Afterwards these wafers were investigated by
electron backscatter diffraction (EBSD) measurements to determine the crystal orientations and the crystallographic
properties of the grain boundaries. Combined EBIC and EBSD results allow the evaluation of the influence of solar
cell processing steps on recombination activity in dependence of several grain boundary types. The gained results
might be important for defect engineering and the development of an optimized solar cell process on cost effective
and impurity-rich silicon material to reduce the recombination activity at grain boundaries in multicrystalline silicon
material.

description: Several `giant' Lyman-$α$ (Ly$α$) nebulae with extent $\gtrsim 300\,$kpc and observed Ly$α$ luminosity of $\gtrsim 10^{44}\,{\rm erg}\,{\rm s}^{-1}\,{\rm cm}^{-2}\,{\rm arcsec}^{-2}$ have recently been detected, and it has been speculated that their presence hints at a substantial cold gas reservoir in small cool clumps not resolved in modern hydro-dynamical simulations. We use the Illustris simulation to predict the Ly$α$ emission emerging from large halos ($M > 10^{11.5}M_{\odot}$) at $z\sim 2$ and thus test this model. We consider both AGN and star driven ionization, and compare the simulated surface brightness maps, profiles and Ly$α$ spectra to a model where most gas is clumped below the simulation resolution scale. We find that with Illustris no additional clumping is necessary to explain the extents, luminosities and surface brightness profiles of the `giant Ly$α$ nebulae' observed. Furthermore, the maximal extents of the objects show a wide spread for a given luminosity and do not correlate significantly with any halo properties. We also show how the detected size depends strongly on the employed surface brightness cutoff, and predict that further such objects will be found in the near future.
