description: In the present work, we consider the cosmological constant model $Λ\proptoα^{-6}$, which is well motivated from three independent approaches. As is well known, the hint of varying fine structure constant $α$ was found in 1998. If $Λ\proptoα^{-6}$ is right, it means that the cosmological constant $Λ$ should also be varying. Here, we try to develop a suitable framework to model this varying cosmological constant $Λ\proptoα^{-6}$, in which we view it from an interacting vacuum energy perspective. Then, we consider the observational constraints on these models by using the 293 $Δα/α$ data from the absorption systems in the spectra of distant quasars. We find that the model parameters can be tightly constrained to the very narrow ranges of ${\cal O}(10^{-5})$ typically. On the other hand, we can also view the varying cosmological constant model $Λ\proptoα^{-6}$ from another perspective, namely it can be equivalent to a model containing "dark energy" and "warm dark matter", but there is no interaction between them. We find that this is also fully consistent with the observational constraints on warm dark matter.

description: Ptilotis leucotis torringtoni Mathews Ptilotis leucotis torringtoni Mathews, 1912c: 80 (Torrington, New South Wales). Now Lichenostomus leucotis novaenorciae (Milligan, 1904). See Salomonsen, 1967: 384, Schodde and Mason, 1999: 240–241, Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 602–603. HOLOTYPE: AMNH 695083, unsexed, collected at Torrington, 29.19S, 151.42E (USBGN, 1957), New South Wales, Australia, in March 1909. From the Mathews Collection (no. 11674) via the Rothschild Collection. COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range as ‘‘ North New South Wales (Queensland?).’’ According to his catalog, Mathews received this specimen from Edwin Ashby; it bears an original label, on which Ashby’s name does not appear, and Mathews and Rothschild type labels. This specimen has the obsolete cream tips on the rectrices characteristic of novaenorciae as defined by Schodde and Mason (1999: 240). There are two specimens that are questionably paratypes: AMNH 695085 (Mathews no. 3228), unsexed, Kurrajong, New South Wales, 31 March 1899, although this locality is hardly in the northern part of the state; and AMNH 695084, unsexed, Coomooboolaroo, Queensland, 1883, by C. Lumholtz, although Mathews questioned its occurrence in Queensland. Robert Collett, ZMO, probably would have sent this latter specimen to Mathews, who was cataloging specimens he received from Collett in early 1912; but I did not find this specimen in Mathews’ catalog. Salomonsen (1967: 384) synonymized torringtoni with nominate leucotis.

description: In this study, we analyze the durability of field aged photovoltaic modules selected 10% from Korea's 4,500 PV sites constructed from 1980 to 2006 year. The standard of judgment for choosing research object is based on manufacturing company supplying most PV module in Korea, installation year and place. Mainly, the phenomenon of PV module’s degradation is corrosion in interconnected ribbon, insulation failure, de-lamination and discoloring of EVA Sheet. In some case, the breakage of bypass diode is discovered. Also, from 18 month installed PV site, the module has no apparent change of appearance. But the maximum power reduced by 1.6% to 3.5% at STC condition. For 4 years PV module, the slight corrosion and humidity permeation on solar cell surface and electrode is detected. This is a project "Durability investigation analysis of field aged PV module" sponsored by Korea government from 2007 to 2010 year and this is the first year of project. The detailed analysis is described in the following paper.

description: The conductivity mobility for majority carrier holes in compensated p-type silicon is
determined by combined measurement of the resistivity and the net doping, the latter via electrochemical
capacitance-voltage measurements. The minority electron mobility was also measured with a technique
based on measurements of diffusivity-limited effective carrier lifetimes. While both minority and
majority carrier mobilities are found to be reduced by compensation, the impact is greater on the minority
electron mobility. The Hall factor, which relates the Hall mobility to the conductivity mobility, has also
been determined using Hall method combined with capacitance-voltage measurements. Our results
indicate a similar Hall factor in both compensated and non-compensated samples.

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 5064-5067
description: The number of PV plant installations in Italy is quickly increasing, mainly due to the large participation
to the national “Conto Energia” Programme. As it is foreseen in the related governmental decree, a detailed
monitoring of selected PV plants, installed in the frame of the Programme, has been started. A group of PV plants
owned by public users has been selected and an accurate data acquisition system has been installed in each plant by
RSE (formerly ERSE), on behalf of GSE and ENEA. The collection of operational data of these PV plants are
currently performed and their analysis is periodically made available on a website. The results of this analysis can be
used to supply information of PV performance and reliability to governmental institutions and PV system operators.
Information are also usable by PV operators (designers, architects, investors, insurance agents, ...), which are
interested in the evaluation of their-own technical and economic involvement in this technology, and by electric grid
managers, that are demanding for the quality, over the years, of PV plants operating in connection to the grid.

by standard energy meters installed in PV grid connected systems in order to be monitored local or remotely. This
communication can be easily implemented as a software program itself or integrated as a part in any other monitoring
software. Remote energy metering for PV grid connected installations is used, exclusively in most of the installations,
by the electrical company for remote energy metering and automatic billing. Energy meters communications from
any manufacturer must fulfill the IEC 870-5-102 standard, mandatory in Spain, and complemented by the Electrical
Grid Company, REE, regulation. For remote energy metering the user must install a GSM modem and supply to the
electrical companies the phone number and counters addresses and passwords in order to perform automatic energy
telereadings using software programs. Local energy metering is easily implementable trough energy meters RS485
network and the communication protocol explained in this work.

description: The amplitude modulation of three dimensional (3D) dust ion-acoustic wave (DIAW) packets is studied in a collisionless magnetized plasma with inertial positive ions, superthermal electrons and negatively charged immobile dust grains. By using the reductive perturbation technique, a 3D-nonlinear Schrödinger (NLS) equation is derived, which governs the slow modulation of DIAW packets. The latter are found to be stable in the low-frequency $(ωω_c$, and the modulational instability (MI) is related to the modulational obliqueness $(θ)$. Here, $ω~(ω_c)$ is the nondimensional wave (ion-cyclotron) frequency. It is shown that the superthermal parameter $κ$, the frequency $ω_c$ as well as the charged dust impurity $(0

description: People with type 2 diabetes (T2D) have a higher risk of cardiovascular (CV) disease (CVD) than those without. This increased risk begins with pre-diabetes, potentially 7–10 years before T2D is diagnosed. Selecting medication for patients with T2D should focus on reducing the risk of CVD and established CVD. Within the last decade, several antihyperglycemic agents with proven CV benefit have been approved for the treatment of hyperglycemia and for the prevention of primary and secondary CV events, including glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors. T2D treatment guidelines recommend that an antihyperglycemic agent with proven CV benefit should be used after metformin in patients with high risk of or established CVD, regardless of glycated hemoglobin levels. Despite the availability of antihyperglycemic agents with proven CV benefit, and guidelines on when to use them, less than one in four patients with T2D and CVD receive this type of therapy. These findings suggest a potential gap between current recommendations and clinical practice. This article reviews the approved agents with CV indications, with a focus on injectable GLP-1RAs, and their place in the T2D treatment paradigm according to current guidelines. We aim to provide primary healthcare providers with in-depth information on subsets of patients who would benefit from this type of therapy and when it should be initiated, taking into consideration safety and tolerability and other disease factors. An individualized treatment approach is increasingly recommended in the management of T2D, employing a shared decision-making strategy between patients and healthcare professionals.

description: The Solsilc process is based upon using high purity raw materials to produce silicon suitable as a feedstock
for solar cell production. The quality of Solsilc-Si has been tested by the solar industry by manufacturing solar cells and
assembly of modules. Ingots for wafering and solar cell processing were made where the input material was a blend of
40% Solsilc-Si and 60% poly-Si. The ingots had resistivity values ranging from 0.6 to 1.2 Ωcm. It was observed that
using Solsilc-Si as a feedstock does not have a negative impact on the wafering process, the wafer properties or the wafer
yield. Furthermore, ingots containing 40% Solsilc-Si obtained comparable cell performances as when using 100% poly-
Si. Despite resistivities below the standard levels for cell production, average cell efficiencies ranging from 16.4 to
16.6% were found. The reverse current measured at -10 V was well below the critical limit (average values ranging from
0.17 to 0.45 A). Two modules were produced which obtained a maximum power of 226.5W (2009) and 233.5W (2010).
These values are within the upper module classification based on 100% poly-Si as a feedstock.

description: Large labeled training sets are the critical building blocks of supervised learning methods and are key enablers of deep learning techniques. For some applications, creating labeled training sets is the most time-consuming and expensive part of applying machine learning. We therefore propose a paradigm for the programmatic creation of training sets called data programming in which users express weak supervision strategies or domain heuristics as labeling functions, which are programs that label subsets of the data, but that are noisy and may conflict. We show that by explicitly representing this training set labeling process as a generative model, we can "denoise" the generated training set, and establish theoretically that we can recover the parameters of these generative models in a handful of settings. We then show how to modify a discriminative loss function to make it noise-aware, and demonstrate our method over a range of discriminative models including logistic regression and LSTMs. Experimentally, on the 2014 TAC-KBP Slot Filling challenge, we show that data programming would have led to a new winning score, and also show that applying data programming to an LSTM model leads to a TAC-KBP score almost 6 F1 points over a state-of-the-art LSTM baseline (and into second place in the competition). Additionally, in initial user studies we observed that data programming may be an easier way for non-experts to create machine learning models when training data is limited or unavailable.

description: This work has been performed in the frame of the PHOTOSIL project dedicated to the purification and
crystallization of metallurgical grade silicon [1]. Compared to electronic grade, purified metallurgical grade presents
high levels of metallic impurities, light elements and dopants. The purpose of the work is to optimize the process
parameters of the segregation and crystallization stages for this particular feedstock, with the aim of obtaining solar
cell conversion efficiencies higher than 15%. We particularly focus on the segregation of impurities, among which
metals, dopants (B and P) and light elements, carbon and oxygen being known to lead to unwanted structures such as
small equiaxed grains (“grits”) and precipitates acting as recombination centers.

description: The 750 GeV diphoton excess reported by ATLAS and CMS indicates the presence of several pairs of the vector-like matter multiplets around TeV scale. If that is the case, radiative corrections from the $SU(3)$ gauge interaction significantly change from those of MSSM, and the infrared-free nature of the gauge interaction leads to characteristic SUSY mass spectra: a ratio of a squark mass to the gluino mass, and scalar trilinear couplings are enhanced at the low-energy scale. Consequently, even in gaugino mediation models, the Higgs boson mass of 125 GeV is explained with the fairly light gluino of 2-3 TeV, which can be accessible at the LHC.

Honda CIGS modules were installed in more than 20 locations in Japan, U.S.A. and Thailand, and high reliability and durability have been confirmed. In October 2007, we started to operate the 27.5MW/year manufacturing line at Honda Soltec Co. Ltd., and made the first step for becoming an “energy production” company. In the manufacturing process, unique technologies such as high temperature selenization, high uniformity “Na spraying”, and environmental friendly CBD-InS buffer have been adopted. The module efficiency of Honda CIGS modules is 11.2%, which is the highest level among the manufacturers for CIGS modules. Residential use modules have been provided already, and in October 2008, we will start to provide new-type industrial use modules.

(RIE) technique to make contact holes for a-Al1-xOx:H passivation layer and optimized RIE conditions and thermal
annealing conditions after metal evaporation. Under the optimum condition, good ohmic contact with low contact
resistance was realized. A good fill factor of 0.795 was obtained for n-type nanocrystalline cubic silicon carbide / ptype
c-Si heterojunction solar cells with the RIE contact process.

description: Selecting stock portfolios and assessing their relative volatility risk compared to the market as a whole, market indices, or other portfolios is of great importance to professional fund managers and individual investors alike. Our research uses the cross-sectional intrinsic entropy (CSIE) model to estimate the cross-sectional volatility of the stock groups that can be considered together as portfolio constituents. In our study, we benchmark portfolio volatility risks against the volatility of the entire market provided by the CSIE and the volatility of market indices computed using longitudinal data. This article introduces CSIE-based betas to characterise the relative volatility risk of the portfolio against market indices and the market as a whole. We empirically prove that, through CSIE-based betas, multiple sets of symbols that outperform the market indices in terms of rate of return while maintaining the same level of risk or even lower than the one exhibited by the market index can be discovered, for any given time interval. These sets of symbols can be used as constituent stock portfolios and, in connection with the perspective provided by the CSIE volatility estimates, to hierarchically assess their relative volatility risk within the broader context of the overall volatility of the stock market.

description: The detrimental influence of transition metals on minority carrier lifetime in solar cells and thus solar
cell performance is up to now not fully understood. In this paper we would like to contribute some new results on this
topic concerning the gettering and deactivation of the transition metals iron (Fe) and copper (Cu) in block cast
multicrystalline (mc) Si material. The investigated processing steps include extended POCl3 gettering and
hydrogenation by firing of a PECVD (Plasma-Enhanced Chemical Vapor Deposition) silicon nitride (SiNx:H). They
are carried out on neighboring wafers using processing conditions which are derived from the standard
photolithography based process at the University of Konstanz (UKN). Sets of neighboring wafers are selected from
bottom, middle and top of an ingot, respectively, to address the varying impurity concentrations e.g. due to
segregation during ingot casting. To extract the specific influence of the transition metals, wafers from intentionally
contaminated mc material were examined. Hydrogenation clearly turned out to have the biggest positive influence on
the contaminated material, while extended gettering showed non-uniform results. In some cases an improvement was
observed, but also degradation of the bulk material occurred.

description: This paper extends an earlier one describing the Higgs boson $H$ as a light composite scalar in a strong extended technicolor model of electroweak symmetry breaking. The Higgs mass $M_H$ is made much smaller than $Λ_{ETC}$ by tuning the ETC coupling very close to the critical value for electroweak symmetry breaking. The technicolor interaction, neglected in the earlier paper, is considered here. Its weakness relative to extended technicolor is essential to understanding the lightness of $H$ compared to the low-lying spin-one technihadrons. Technicolor cannot be completely ignored, but implementing technigluon exchange together with strong extended technicolor appears difficult. We propose a solution that turns out to leave the results of the earlier paper essentially unchanged. An argument is then presented that masses of the spin-one technifermion bound states, $ρ_H$ and $a_H$, are much larger than $M_H$ and, plausibly, controlled by technicolor. Assuming $M_{ρ_H}$ and $M_{a_H}$ are in the TeV-energy region, we identify $ρ_H$ and $a_H$ with the diboson excesses observed near $2\,{\rm TeV}$ by ATLAS and CMS in LHC Run 1 data, and we discuss their phenomenology for Runs 2 and 3.

description: Taiwan has 10-year experiences on PV installation promotions. Several subsidized programs were
conducted since 2000 to demonstrate different applications of PV. The progress is amazing in terms of contract number
and contract capacity. The number of subsidized contracts explosively grows from 8 cases (59.40kWp totally) in 2000 to
810 cases (33.646MWp totally) in 2009. Grid-connected systems absolutely dominated the PV market in Taiwan
although stand-alone systems were introduced at first. The yields of 438 grid-connected PV systems were investigated.
The results of 2009 show that the season effect on PV yields are larger for northern Taiwan than middle or southern
Taiwan. The average annual daily mean yields of southern Taiwan, middle Taiwan, and northern Taiwan are 3.61
kWh/day/kWp, 3.46 kWh/day/kWp, and 2.96 kWh/day/kWp in 2009, respectively. The average annual daily mean yield
is 0.65kWh/d/kWp higher in southern Taiwan than in northern Taiwan. The PV yields have large difference in different
regions, although the area of Taiwan is small. Thus, selecting a PV site should be very careful for a best investment in PV
energy generation.

shortage of purified silicon between 2004 and 2008 induced a strong price increase and trigged a capacity expansion
as well as the introduction in ingot production of the so called “upgraded metallurgic grade silicon” (UMG-Si) as a
feedstock. However, new solar grade silicon might contain significant higher fractions of impurities. It is well known
their impact on the final cell quality but the debate is open about what are the acceptable contamination levels within
the purified silicon feedstock also because it is well known that during the growth process and cell manufactory the
material quality improves. In the recent period in the market there is an increasing availability of silicon feedstock at
lower cost but its quality is not always guaranteed.
In this paper we report a new fast in line characterization tools for feedstock analysis based on the Laserinduced
breakdown spectroscopy. We applied this technique to the characterization of metallurgic grade silicon
feedstock with the aim of valuate the applicability of this technique in the photovoltaic industry as in-line portable
characterization tool. Different silicon grade feedstock were analyzed and selectivity and detection limit for the main
impurities present in the silicon feedstock were determined.

description: The influence of compensation at solar cell and wafer levels was investigated on Czochralski grown p-type mono
crystalline silicon materials. The efficiency of solar cells was highest (17%) and invariant with compensation for
compensation ratio (Rc) below approximately 1.5. Beyond this, solar cell parameters tend to degrade with increasing
Rc. As observed in a standard P-gettering process, the average bulk lifetime for a given substrate resistivity tends to
decrease with increase in Rc. An extended gettering process, consisting of P-diffusion at 850°C followed by in-situ
P-gettering at 800°C for 30 minutes, gave better lifetime values than the standard gettering for all compensation
levels. The lifetime values of highly compensated materials were increased significantly by such an extended
gettering process.
Temporal stability of lifetime on P-gettered samples gave an indication of slow degradation of lifetimes in the dark
(DID). Accelerated light induced degradation further enhances this process, suggesting that this dark degradation
effect could be due to BO2i complexes in compensated samples where Fei is extremely low (ppba). However this
effect has little impact on solar cell parameters.

description: We define in this paper a class of three indices tensor models, endowed with $O(N)^{\otimes 3}$ invariance ($N$ being the size of the tensor). This allows to generate, via the usual QFT perturbative expansion, a class of Feynman tensor graphs which is strictly larger than the class of Feynman graphs of both the multi-orientable model (and hence of the colored model) and the $U(N)$ invariant models. We first exhibit the existence of a large $N$ expansion for such a model with general interactions. We then focus on the quartic model and we identify the leading and next-to-leading order (NLO) graphs of the large $N$ expansion. Finally, we prove the existence of a critical regime and we compute the critical exponents, both at leading order and at NLO. This is achieved through the use of various analytic combinatorics techniques.

description: Mit der vorliegenden Arbeit wurden neue Erkenntnisse bei der Aufklärung der Mechanismen, die für die Reaktivität von Übergangsmetall- und Metalloxid-Clustern verantwortlich sind, gewonnen. Dies ist aus zwei Gründen gelungen: Zum einen erlaubt die gradienten-korrigierte Dichtefunktional-Methode eine zuverlässige Beschreibung von strukturellen und energetischen Eigenschaften dieser Cluster, insbesondere durch die Entwicklung einer neuen Generation von Hybrid-Austausch- und Korrelations-Funktionalen im Rahmen der verallgemeinerten Gradienten-Näherung. Diese wurden erstmalig in entsprechenden quantenchemischen Programmen implementiert und getestet. Zum zweiten stellte die fruchtbare Zusammenarbeit mit den experimentellen Bereichen, eine Herausforderung für die Theorie dar, mittels der gewonnenen Erkenntnisse zur konzeptionellen Planung der Experimente beizutragen (A. Fielicke, Dissertation, Humboldt-Universität zu Berlin, 2001).
description: In this work the transition metal and metal oxide clusters has been investigated with the aim of gaining a better insight into the mechanisms which govern their reactivity. The theoretical study of the structural and energetic properties of the clusters has been carried out within the framework of the density functional theory by means of a new family of gradient-corrected hybrid density functionals which has been coded for the first time into quantum chemistry packages. The theoretical findings stimulated the experimental investigation of the gas phase reactivity of these species which confirmed the correctness of the reaction mechanism models proposed (A. Fielicke, Doctoral Thesis, Humboldt-Universität zu Berlin, 2001).

description: Quark-lepton compositeness is a well-known beyond the Standard Model (SM) scenario with heavy exotic particles like leptoquarks (LQs) and leptogluons (LGs) etc. These particles can couple to leptons and jets simultaneously. In this letter, we use the recent CMS scalar LQ search data in the $eejj$ and $eej$ channels to probe this scenario. We recast the data in terms of a color octet partner of the SM electron (or a first generation spin-1/2 LG) that couples to an electron and a gluon via a dimension five operator suppressed by the quark-lepton compositeness scale ($Λ$). By combining different production processes of the color octet electron ($e_8$) at the LHC, we use the CMS 8TeV data to obtain a simultaneous bound on $Λ$ and the mass of the $e_8$ ($M_{e_8}$). We also study the reach of the 13 TeV LHC to discover the $e_8$ and interpret the required luminosity in terms of $M_{e_8}$ and $Λ$.

AN ATTRIBUTION THEORY APPROACH TO BRANDS' ANTI-SOCIAL MEDIA CSR EFFORTS

description: Brands often use social media platforms to promote their Corporate Social Responsibility (CSR) programs, what can even potentially evoke external CSR attributions, but what is the case if the proposed initiative is exactly to quit social media, in defense of mental health? Is purchase intention higher when consumers are still able to engage with brands online or when the exact opposite happens, with brands’ decisions to disconnect? Through the lenses of Attribution Theory, the present study employed an experimental study to test consumers’ intrinsic and extrinsic motive attributions, brand attitude, purchase intention and perceived message effectiveness upon a fictional brand’s anti-social media initiative. Three conditions varying in message-practice consistency and time consistency (Uniform-long, Uniform-short and Washing) were employed. Results indicate that consumers attribute intrinsic motives when consistency is present, which, in turn, leads to more favorable evaluations. Theoretical and managerial implications are discussed.

description: Activity theory has long been an influential framework in the field of education. However, its theoretical concepts are not easily grasped by scholars, mainly due to difficulties in translation from the original Russian works, the complexity of these concepts and multiple versions embedded within the tradition. The two major approaches within activity theory were established by Leontiev and another version proposed later by Engeström, and they have often been confused and conflated together in the literature. This paper provides a much-needed theoretical comparison between these approaches in regard to the field of education. The criteria for comparison involve their theoretical foundations, central phenomena of interest, key theoretical concepts, units of analysis and explanatory mechanisms. Insights from this paper contribute to establishing a more refined understanding of activity theory and its variants, which in turn allows researchers to make more informed decisions when selecting and using these frameworks. Implications for practical research practices are discussed with examples from the area of teacher professional development.

description: We study the network dismantling problem, which consists in determining a minimal set of vertices whose removal leaves the network broken into connected components of sub-extensive size. For a large class of random graphs, this problem is tightly connected to the decycling problem (the removal of vertices leaving the graph acyclic). Exploiting this connection and recent works on epidemic spreading we present precise predictions for the minimal size of a dismantling set in a large random graph with a prescribed (light-tailed) degree distribution. Building on the statistical mechanics perspective we propose a three-stage Min-Sum algorithm for efficiently dismantling networks, including heavy-tailed ones for which the dismantling and decycling problems are not equivalent. We also provide further insights into the dismantling problem concluding that it is an intrinsically collective problem and that optimal dismantling sets cannot be viewed as a collection of individually well performing nodes.

description: Using Hubble data, including new grism spectra, Oesch et al. recently identified GN-z11, an $M_\textrm{UV}$=-21.1 galaxy at $z$=11.1 (just 400Myr after the big bang). With an estimated stellar mass of $\sim$10$^9$M$_{\odot}$, this galaxy is surprisingly bright and massive, raising questions as to how such an extreme object could form so early in the Universe. Using \Meraxes{}, a semi-analytic galaxy-formation model developed as part of the Dark-ages Reionization And Galaxy-formation Observables from Numerical Simulations (DRAGONS) programme, we investigate the potential formation mechanisms and eventual fate of GN-z11. The volume of our simulation is comparable to that of the discovery observations and possesses two analogue galaxies of similar luminosity to this remarkably bright system. Existing in the two most massive subhaloes at $z$=11.1 ($M_\textrm{vir}$=1.4$\times 10^{11}$M$_{\odot}$ and 6.7$\times 10^{10}$M$_{\odot}$), our model analogues show excellent agreement with all available observationally derived properties of GN-z11. Although they are relatively rare outliers from the full galaxy population at high-$z$, they are no longer the most massive or brightest systems by $z$=5. Furthermore, we find that both objects possess relatively smooth, but extremely rapid mass growth histories with consistently high star formation rates and UV luminosities at $z{>}11$, indicating that their brightness is not a transient, merger-driven feature. Our model results suggest that future wide-field surveys with the \textit{James Webb Space Telescope} may be able to detect the progenitors of GN-z11 analogues out to $z{\sim}$13--14, pushing the frontiers of galaxy-formation observations to the early phases of cosmic reionization and providing a valuable glimpse of the first galaxies to reionize the Universe on large scales.

description: In industrial production of multi crystalline solar cells acid texturing is nowadays a standard process.
Likely the most used process in industry is the “UKN” process, developed at the University of Konstanz, using HF,
HNO3 and H2O. Here results for a new acid texturisation solution comprising HF, HNO3, H2SO4 and H2O are
presented. Lab results show the potential of the new solution. An industrial test with 100 000 wafers shows that the
new solution (named SelTex 6.5) reduces the breakage by 23% due to reduced grain boundary etching. Additionally
the efficiency is increased by 0.1% while the costs are reduced by at least 10%.
