PV Modules

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 1942-1945
description: Current solar simulators only focus on steady-state or pulsed (flasher) irradiance conditions, under
standard test condition, to measure peak performance of photovoltaic modules. For realistic scenarios other more
dynamic conditions are needed, such as lower irradiance levels that change over time and shading patterns (from
clouds and surrounding objects). This work presents a low-cost indoor dynamic illumination setup to test smart PV
modules under dynamic conditions of irradiance. It enables the effective evaluation of its performance, allowing
temporal and spatial irradiance variation. This setup is be able to simulate conditions close to realistic outdoor
patterns enabling. For example, to simulate irradiance conditions in countries such as Belgium with highly variable
irradiance which changes constantly in space and time.

description: The minimal and maximal operators generated by the Bessel differential expression on the finite interval and a half-line are studied. All non-negative self-adjoint extensions of the minimal operator are described. Also we obtain a description of the domain of the Friedrichs extension of the minimal operator in the framework of extension theory of symmetric operators by applying the technique of boundary triplets and the corresponding Weyl functions, and by using the quadratic form method.

description: PV module suppliers give long-term guarantees on minimum power output for their products, but at the
same time an enormous pressure on costs leaves no room for over engineering the PV modules in terms of required
service life and reliability. As IEC certification tests are not designed to test modules for wear out and not to
guarantee a certain service, combined and longer stress tests are proposed. However, highly accelerated life tests in
the laboratory do not reproduce the combined stress factors of a real environment. Therefore results from outdoor
exposure testing of modules can supply valuable complementary information especially if they are executed at sites
with challenging climates. A 3X mirror concentrator test system for full size PV modules is presented which
combines and even accelerates natural stress factors. It exhibits 2.5x higher irradiation load compared to fixed rack
exposure, irradiance levels up to 3000 W/m², elevated operating temperatures and frequent temperature cycling
inducing thermo-mechanical stresses. The test bed has a manifold of applications including accelerated durability
examination, quick assessment of initial field stabilisation of PV modules (light soaking, LID) or the projection of
damage propagation. The paper discusses the stress levels induced by the 3X-concentrator in detail and presents
examples of PV module testing tasks.

description: After the recent publication of a couple of succinct and overarching essays covering the state of the field in the history of political thought (in the English language), Prof. Davide Cadeddu from the University of Milan expressed polemical remarks on some of their content. At the same time, he asked for comments on his own article, inviting the response several of English-speaking scholars (or scholars educated in anglophone cultural context). In response to this challenge, ten colleagues John Dunn (King’s College, University of Cambridge) Humeira Iqtidar (King’s College London) Iain Hampsher-Monk (University of Exeter) Richard Bourke (King’s College, University of Cambridge) Adrian Blau (King’s College London) Alexandra Chadwick (University of Jyväskylä) Duncan Kelly (Jesus College, University of Cambridge) David Leopold (Mansfield College, University of Oxford) Peter Burke (Emmanuel College, University of Cambridge) Richard Whatmore (University of St Andrews) answered with texts of different length and complexity. Depending on each case individually, each scholar was either in agreement or disagreement with the statements previously formulated by him, henceforth eliciting, more or less implicitly, new reflections on the matter at hand.

description: The structure of $^{35}$P was studied with a one-proton knockout reaction at88~MeV/u from a $^{36}$S projectile beam at NSCL. The $γ$ rays from thedepopulation of excited states in $^{35}$P were detected with GRETINA, whilethe $^{35}$P nuclei were identified event-by-event in the focal plane of theS800 spectrograph. The level scheme of $^{35}$P was deduced up to 7.5 MeV using$γ-γ$ coincidences. The observed levels were attributed to protonremovals from the $sd$-shell and also from the deeply-bound $p\_{1/2}$ orbital.The orbital angular momentum of each state was derived from the comparisonbetween experimental and calculated shapes of individual ($γ$-gated)parallel momentum distributions. Despite the use of different reactions andtheir associate models, spectroscopic factors, $C^2S$, derived from the$^{36}$S $(-1p)$ knockout reaction agree with those obtained earlier from$^{36}$S($d$,\nuc{3}{He}) transfer, if a reduction factor $R\_s$, as deducedfrom inclusive one-nucleon removal cross sections, is applied to the knockout transitions.In addition to the expected proton-hole configurations, other states were observedwith individual cross sections of the order of 0.5~mb. Based on their shiftedparallel momentum distributions, their decay modes to negative parity states,their high excitation energy (around 4.7~MeV) and the fact that they were notobserved in the ($d$,\nuc{3}{He}) reaction, we propose that they may resultfrom a two-step mechanism or a nucleon-exchange reaction with subsequent neutronevaporation. Regardless of the mechanism, that could not yet be clarified, thesestates likely correspond to neutron core excitations in \nuc{35}{P}. Thisnewly-identified pathway, although weak, offers the possibility to selectivelypopulate certain intruder configurations that are otherwise hard to produceand identify.

description: In this paper we investigate new approaches to enhance recovery of valuable materials during the
recycling of crystalline Si (cSi) PV modules. The recycling of out-of-specs, damaged or end-of-life cSi PV modules
will gradually become more important for PV suppliers and recyclers. Also recycling can help to further reduce
carbon and environmental footprint of cSi PV. We tested two approaches to enhance recyclability of frame, glass, and
silicon. The research was based on ECN’s conductive back-contact module technology. First, alternative edge
sealants, easy to release from the module, were tested on their protection against air and moisture ingress into the
module. Several alternatives were established which show comparable protection as the state-of-the-art silicone-based
or double-sided adhesive tape edge sealants, but are much more easy to remove. Second, thermoplastic encapsulant
was investigated as a method to improve recyclability of PV modules. The thermoplastic encapsulant used in this
study results in PV modules with improved resistance to damp heat (DH) conditions, compared to EVA-based
modules. The separation of the components (cells, glass, backsheet) in PV laminates with this thermoplastic
encapsulant, using a wire saw device at temperatures around 200 degrees C, was demonstrated. This method may
allow recovering of intact solar cells out of end-of-life, out-of-specs or damaged PV modules.

among P-multi, P-mono front contact and N-mono back contact module. We perform different types of cocktail
sequence and compare for the correlation of degradation to test sequential order. [DH-HF] sub-sequence shows more
severe synergy effect than [TC-HF] sub-sequence does. P-multi module suffers more damage in HF test, while Pmono
is prone to be UV damaged. Back contact module owns excellent reliability especially when POE is instead of
EVA encapsulation material. Faults and failure modes by cocktail sequential test are similar to those observed in the
field, and it refers a possible methodology approach to simulate module reliability during PV system operation.

description: Simulation from the truncated multivariate normal distribution in high dimensions is a recurrent problem in statistical computing, and is typically only feasible using approximate MCMC sampling. In this article we propose a minimax tilting method for exact iid simulation from the truncated multivariate normal distribution. The new methodology provides both a method for simulation and an efficient estimator to hitherto intractable Gaussian integrals. We prove that the estimator possesses a rare vanishing relative error asymptotic property. Numerical experiments suggest that the proposed scheme is accurate in a wide range of setups for which competing estimation schemes fail. We give an application to exact iid simulation from the Bayesian posterior of the probit regression model.

PV Modules

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 1907-1910
description: With increasing global supply of photovoltaic (PV) modules into free field as well as building added applications,
product safety aspects have received increased attention. To address the latter Working Group 2 (WG2) of the
Technical Committee for Solar Photovoltaic Energy Systems (TC 82) of the International Electrotechnical
Commission (IEC) invested a considerable effort in updating the governing PV module safety standards – IEC 61730
series. Part 1 of IEC 61730 addresses the minimum requirements for module design while Part 2 covers the required
test protocols and test sequences.
In particular, PV system voltages of up to 1.500 V d.c. impose requirements on component materials and module
construction that deserve a more detailed explanation rooted in international horizontal standards. A key underlying
concept relevant to electrical safety is Insulation Coordination in accordance to IEC 60664 taking into consideration
the service environment of the PV module as well as the system voltage (Pollution Degree and Overvoltage
Category). Resulting from the latter are material properties (Material Groups) and construction requirements
(spacing) governing protection against electric shock – e.g., type of insulation (basic, double, functional, reinforced,
solid), minimum clearances (cl) and creepage distances (cr) as well as distance through insulation (dti) for cemented
joints.
This paper explains how the governing horizontal standard of Insulation Coordination (IEC 60664) relates to specific
material and construction requirements of PV modules as a function of their intended use and application (system
voltage, deployment environment) and the resulting requirements laid down in the new IEC 61730 series. A generic
example will be given at the end to ease understanding.

description: In comparison with the evaluation of hail events in the field, a quantitative analysis of hail impact dependent of
mass and velocity of the ice balls has been started. Glass breakage and star cracks of the solar cells are the typical failure
modes of hail events in the field and in the lab. We found that the location of the hail impact on the PV module is a key
parameter for both failures due to different stresses and strains of the glass after the hail impact. Hail tests according to IEC
61215 (Clause 10.17) [1] and VKF (Swiss hail protection register) [2] were performed with different PV module types to
analyze the effect of strong hail impacts
On the Concavity of Auxiliary Function in Classical-Quantum Channels

description: The auxiliary function of a classical channel appears in two fundamental quantities that upper and lower bound the error probability, respectively. A crucial property of the auxiliary function is its concavity, which leads to several important results in finite block length analysis. In this paper, we prove that the auxiliary function of a classical-quantum channel also enjoys the same concave property, extending an earlier partial result to its full generality. The key component in our proof is a beautiful result of geometric means of operators.

description: A non-negligible source of systematic bias in cosmological analyses of galaxy surveys is the on-sky modulation caused by foregrounds and variable image characteristics such as observing conditions. Standard mitigation techniques perform a regression between the observed galaxy density field and sky maps of the potential contaminants. Such maps are ad-hoc, lossy summaries of the heterogeneous sets of co-added exposures that contribute to the survey. We present a methodology to address this limitation, and extract the spurious correlations between the observed distribution of galaxies and arbitrary stacks of single-epoch exposures. We study four types of galaxies (LRGs, ELGs, QSOs, LBGs) in the three regions of the DESI Legacy Surveys (North, South, DES), which results in twelve samples with varying levels and type of contamination. We find that the new technique outperforms the traditional ones in all cases, and is able to remove higher levels of contamination. This paves the way for new methods that extract more information from multi-epoch galaxy survey data and mitigate large-scale biases more effectively.

We construct irreducible calibrated representations and describe the calibrated spectrum. This is done in terms of new families of combinatorial objects equipped with actions of the corresponding Weyl groups. These objects are built from and generalise the usual standard Young tableaux, and are controlled by the considered affine Hecke algebras. By restriction and limiting procedure, we obtain several combinatorial models for representations of finite Hecke algebras and Weyl groups of type ADE. Representations are constructed by explicit formulas, in a seminormal form.

description: Standard testing conditions as IEC and UL were not developed for applications in climates such as the
Atacama Desert, which is well known for extremely high irradiation levels (also UV), large temperature gradients,
corrosive environment, partial high humidity (“camanchaca”) and a really fine dust (“chusca”). Therefore the PV
system performance and longevity is strongly affected, and the standards are only partly applicable to determine the
module stability against climatic impacts. In the present study, we investigate the performance of different setups of
half-size and full-size cell modules under accelerated indoor test conditions, performed at ISC Konstanz, Germany
and later installed at the Solar Platform of the Atacama Desert (PSDA) in Yungay, Chile. We fabricated minimodules
employing variations of glass thickness, cell configurations (p- and n-type), 3 types of encapsulants (EVA,
low UV light cut-off EVA and thermoplastic material), 3 different backsheets (white standard, transparent and desert
type) and glass-glass configurations. After 6000 hours of damp heat (DH) exposure the groups perform differently
due the encapsulated materials used. Best results are observed with thermoplastic material, regardless of the
backsheet used. The humidity freeze 41 (HF) and UV62 test reveals a negligible degradation for all module
configurations. Thermo-cycling 200 (TC) shows less relative Pmpp losses when glass on the rear side is used, while
half-size cell modules are more sensitive for thermal stress than full-size cell modules, showing more defects such as
cracks and metallization damages. Finally, preliminary outdoor measurements carried out at the PSDA and in
Konstanz reveal that the ARC glass helps to improve the performance ratio (PR) up to 1%. The full-cell size modules
show a strong PR decay above 800 Wm-2 whereas for half-size cell modules with ARC the specific yield is up to
2.3% higher compared to standard glass and up to 4.3% higher than for full-size cell modules above 900 Wm-2.

description: Key Messages • In most African countries, there has been a policy shift away from treating small-scale aquaculture as a tool for achieving household food security towards the prioritization of sustainable commercial aquaculture. If embraced in Malawi, this shift can attract both domestic and foreign investment. • Investing in research can transform the aquaculture sector. Genetic improvement programs, in particular, will result in a greater availability of high-quality fingerlings. • Following the examples of the top aquaculture-producing countries in Africa, the Government of Malawi should provide incentives for private sector investment in diversified feed production, research, and aquaculture production. • Adoption of innovative technologies and best farm management practices (such as cage culture) is key for boosting aquaculture productivity and profitability. • Domestication and implementation of the SADC regional plans (including the Aquaculture Strategy, Aquatic Animal Health Strategy, and Regional Value Chain Priority Action Roadmap) will promote regional cooperation that could lead to greater trade in fish products and help to achieve regional integration.

Using the concepts of virtual qubits and virtual temperatures, we show that higher dimensional machines can outperform smaller ones. For instance, by considering refrigerators with more levels, lower temperatures can be achieved, as well as higher power. We discuss the optimal design for refrigerators of a given dimension. As a consequence we obtain a statement of the third law in terms of Hilbert space dimension: reaching absolute zero temperature requires infinite dimension. These results demonstrate that Hilbert space dimension should be considered a thermodynamic resource.

description: The impact of reference modules in power rating of PV-modules in the industry is vital. Often the
practices used in the industry may deviate to the standard and reference modules of different bill of materials are used
than the rated modules. The impact of unmatched with different glass/EVA/backsheet encapsulation on the power rating
is the topic of this work. Glass, encapsulants and backsheets respond differently to direct and diffusive components of
irradiance altering the angular response of the device. The first may introduce angular mismatch which may exceed ±1%,
k=2 in solar simulators with considerable diffusive light out of a field of view of 30°. In such cases the diffusive
component of solar simulator light is significant. In addition glass and EVA combinations may impact the SR response of
the device and in particular the UV response. The underlying spectral mismatch may introduce errors, which exceed 2%
even in solar simulators of class A spectral matching. Last, but not least it is shown that when consistent rating methods
are applied, the combined measurement uncertainty of angular and spectral mismatch can be reduced to ±0.35%, k=2;
practically the measurement uncertainty itself.

description: Back-contact modules based on Metal Wrap-Through solar cells, conductive backsheets and
electrically conductive adhesives are a promising technology because of the potential for high performance, high
productivity and better module appearance. In this paper, we discuss the importance of key module materials, in
particular the electrically conductive adhesive, and describe the automated module assembly. The modules that are
obtained show robust and reliable performance, and pass all critical standard accelerated tests. They also perform
well in extended aging tests and pass Potential Induced Degradation testing. For the first time for this type of
module, outdoor test results of a sizable system are given. It is demonstrated that these modules show strong
performance in the field and a slight increase of specific yield compared to standard modules is observed.

description: We explore the butterfly effect for black holes with rotation or charge. We perturb rotating BTZ and charged black holes in 2+1 dimensions by adding a small perturbation on one asymptotic region, described by a shock wave in the spacetime, and explore the effect of this shock wave on the length of geodesics through the wormhole and hence on correlation functions. We find the effect of the perturbation grows exponentially at a rate controlled by the temperature; dependence on the angular momentum or charge does not appear explicitly. We comment on issues affecting the extension to higher-dimensional charged black holes.

LOTUS: A (non-)LTE Optimization Tool for Uniform derivation of Stellar atmospheric parameters

description: Precise fundamental atmospheric stellar parameters and abundance determination of individual elements in stars are important for all stellar population studies. Non-Local Thermodynamic Equilibrium (Non-LTE; hereafter NLTE) models are often important for such high precision, however, can be computationally complex and expensive, which renders the models less utilized in spectroscopic analyses. To alleviate the computational burden of such models, we developed a robust 1D, LTE and NLTE fundamental atmospheric stellar parameter derivation tool, $\texttt{LOTUS}$, to determine the effective temperature $T_{\mathrm{eff}}$, surface gravity $\log g$, metallicity $\mbox{[Fe/H]}$ and microturbulent velocity $v_{\mathrm{mic}}$ for FGK type stars, from equivalent width (EW) measurements of Fe I and Fe II lines. We utilize a generalized curve of growth method to take into account the EW dependencies of each Fe I and Fe II line on the corresponding atmospheric stellar parameters. A global differential evolution optimization algorithm is then used to derive the optimized fundamental parameters. Additionally, $\texttt{LOTUS}$ can determine precise uncertainties for each stellar parameter using a Markov Chain Monte Carlo (MCMC) algorithm. We test and apply $\texttt{LOTUS}$ on a sample of benchmark stars, as well as stars with available asteroseismic surface gravities from the K2 survey, and metal-poor stars from $R$-process Alliance (RPA) survey. We find very good agreement between our NLTE-derived parameters in $\texttt{LOTUS}$ to non-spectroscopic values within $T_{\mathrm{eff}}=\pm 30$ K and $\log g=\pm 0.10$ dex for benchmark stars. We provide open access of our code, as well as of the interpolated pre-computed NLTE EW grids available on Github, and documentation with working examples on Readthedocs.

description: Energy fluctuation of ideal Fermi gas trapped under generic power law potential $U=\sum_{i=1} ^d c_i |\frac{x_i}{a_i}|^{n_i}$ have been calculated in arbitrary dimension. Energy fluctuation is scrutinized further in the degenerate limit $μ>> K_BT$ with the help of Sommerfeld expansion. The dependence of energy fluctuation on dimensionality and power law potential is studied in detail. Most importantly our general result can exactly reproduce the recently published result regarding free and harmonically trapped ideal Fermi gas in d=3 (S Biswas, J Mitra, S Bhattacharyya, J. Stat. Mech. P03013, 2015.)

PV Modules

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 1862-1865
description: DuPont has a deep interest in long-term module reliability in relation to our products for the solar
market. We have several thrusts to study the interactions of photovoltaic module component materials and their
impact on module durability from a holistic point of view. While the impact of backsheets and encapsulants on
module durability has been studied to a great extent by DuPont and others, the role of metallization pastes is
significantly less understood. One durability-related aspect of metallization pastes is their adhesion strength to the
tabbing ribbons. We have developed methods to control adhesion over a wide range and are among the first to
quantify the impact of adhesion on module durability. A second thrust is the interactions between module
components in the formation of snail trails on the surface of PV modules. Our investigation into the influence of
micro-cracks as well as the material properties of encapsulants and backsheets on the rates of water ingression and
subsequent snail trail formation is presented. We also discuss the development and effectiveness of accelerated test
methodologies replacing the current time-consuming field aging test method to establish snail trail susceptibility and
rate of formation, thereby applying them to specific module designs. Data from module field exposure tests is
presented to correlate with lab accelerated aging tests.
Anatomy of rocky planets formed by rapid pebble accretion I. How icy pebbles determine the core fraction and FeO contents

description: We present a series of papers dedicated to modelling the accretion and differentiation of rocky planets that form by pebble accretion within the lifetime of the protoplanetary disc. In this first paper, we focus on how the accreted ice determines the distribution of iron between the mantle (oxidized FeO and FeO$_{1.5}$) and the core (metallic Fe and FeS). We find that an initial primitive composition of ice-rich material leads, upon heating by the decay of $^{26}$Al, to extensive water flow and the formation of clay minerals inside planetesimals. Metallic iron dissolves in liquid water and precipitates as oxidized magnetite Fe$_3$O$_4$. Further heating by $^{26}$Al destabilizes the clay at a temperature of around 900 K. The released supercritical water ejects the entire water content from the planetesimal. Upon reaching the silicate melting temperature of 1,700 K, planetesimals further differentiate into a core (made mainly of iron sulfide FeS) and a mantle with a high fraction of oxidized iron. We propose that the asteroid Vesta's significant FeO fraction in the mantle is a testimony of its original ice content. We consider Vesta to be a surviving member of the population of protoplanets from which Mars, Earth, and Venus grew by pebble accretion. We show that the increase in the core mass fraction and decrease in FeO contents with increasing planetary mass (in the sequence Vesta -- Mars -- Earth) is naturally explained by the growth of terrestrial planets outside of the water ice line through accretion of pebbles containing iron that was dominantly in metallic form with an intrinsically low oxidation degree.
