description: Large area plasma coating with PECVD processes for applications in silicon wafer cell technology
is a well established process. Roth&Rau AG is successfully at the market for more than ten years by applying
microwave plasmas at linear plasma sources ([1], [2]). Current PECVD equipment roadmaps following
corresponding cell technology roadmaps towards grid parity show that increased deposition speed is one of the
most influence factors for future cost effective inline equipments.
Following and refining the microwave plasma source developed in 2009 [3], an up to 100% faster PECVD process
for silicon nitride as front antireflection coating could be developed and demonstrated together with cell results.
Silicon nitride layer analysis is carried out by optical characterization (ellipsometer) and FTIR analysis (hydrogen
content, Si-N bond density). Excellent layer homogeneity results can be reached by additional features integrated
in the plasma sources like distributed gas shower control.
The contribution shows experimental details for the SiN PECVD process in regard of high deposition speed,
improved homogeneity control and scalability of the process to the modular PECVD equipment line SiNA®
covering a wafer throughput from 1200 up to 4000 wafers/hour.

description: Most unaccompanied migrant children from Central America who make it across the US-Mexico border and into Office of Refugee Resettlement (ORR) custody remain in short-term shelters while awaiting reunification. While many children go on to join family members, those with limited options, are placed in long term foster care (LTFC) while they await their legal cases to be adjudicated. This group is largely invisible in research on unaccompanied migrant children because of the restricted and opaque nature of long-term foster care. This thesis analyzes, through a geopolitical feminist framework, their particular struggles as they navigate between the immigration and foster care systems. Based on over six months of participant observation/accompaniment of foster care children with an NGO, a review of case files, interviews with key informants, and courtroom ethnography, this study aims to identify the challenges and daily struggles faced by Central American unaccompanied children in the U.S. federally funded long term foster care and immigration system. Through a conceptual lens integrating feminist geopolitics, children’s geographies, accompaniment theory/activist/engaged research, and testimonio, this research centers the perspectives of children and their advocates as they navigate the vagaries of pursuing asylum and special immigrant juvenile status (SIJS). Specifically, it analyzes how unaccompanied children employ agentic strategies to negotiate long term foster care and the evolving changes in immigration law/policy. Finally, it provides recommendations for how activists and legal representatives can better support and advocate for the needs of children in long term foster care, who are simultaneously navigating the child welfare system and the process to obtain legal status. This paper contributes to the limited literature on the experiences of unaccompanied migrant children in foster care and offers preliminary insights into the policy and advocacy needs to better support this vulnerable population.

description: Angular momentum transport in magnetic multilayered structures plays a central role in spintronic physics and devices. The angular momentum currents or spin currents are carried by either quasi-particles such as electrons and magnons, or by macroscopic order parameters such as local magnetization of ferromagnets. Based on the generic interface exchange interaction, we develop a microscopic theory that describes interfacial spin conductance for various interfaces among non-magnetic metals, ferromagnetic and antiferromagnetic insulators. Spin conductance and its temperature dependence are obtained for different spin batteries including spin pumping, temperature gradient and spin Hall effect. As an application of our theory, we calculate the spin current in a trilayer made of a ferromagnetic insulator, an antiferromagnetic insulator and a non-magnetic heavy metal. The calculated results on the temperature dependence of spin conductance quantitatively agree with the existing experiments.

description: Poröses Silizium ist ein äußerst vielseitiges Funktionsmaterial. In dieser Arbeit werden zwei verschiedene, von der Elektrochemie inspirierte Ansätze entwickelt und untersucht, um eine Aktuator-funktion in poröses Silizium zu integrieren. Der erste Ansatz zielt auf die Nutzung der elektrochemisch-mechanischen Kopplung an der Grenzfläche einer porösen Siliziumelektrode, die in eine wässrige Elektrolytlösung eingetaucht ist. Beim zweiten Ansatz wird das elektroaktive, elektrisch leitfähige Polymer Polypyrrol in die poröse Siliziumporenstruktur integriert, um ein Hybridmaterial zu schaffen. Beide Ansätze erzielen eine robuste und hoch reproduzierbare Aktuation, die dem angelegten Potential linear folgt und deren Arbeitsdichte mit klassischen Piezoaktoren vergleichbar ist.
description: Porous silicon is highly versatile functional material. In this thesis two different electrochemistry-inspired approaches are developed and investigated to integrate an actuator functionality into porous silicon. The first approach aims to utilise electrochemo-mechanical coupling at the interface of a porous silicon electrode immersed in an aqueous electrolyte solution. The second approach comprises the integration of the electroactive, electrically conductive polymer polypyrrole into the porous silicon pore structure to create a hybrid material. Both approaches achieve a robust and highly reproducible actuation that follows the applied potential linear and whose work density compares well to classical piezo actuators.

description: Nowadays several kinds of silicon wafers can be used for solar cells manufacturing. Bulk resistivity of
wafers and shunt resistance of cells are parameters with significant influence in electrical performance. We have
sorted out several groups of monocrystalline solar cells attending to them. After measuring their efficiency variation
at different irradiance levels, we have manufactured modules and investigated on their performance regarding the
resistivity of the wafers and the shunt resistance of the cells. In our paper we will estimate differences between
several groups of cells and modules.

description: Precise measurement of the current-voltage (I-V) curve is the essential technology for characterizing
the performance of the solar cells. The I-V curves of the crystalline silicon (c-Si) bare cells are usually measured by
using sample stages with multiple contact probes. It has been recently recognized that the I-V curves of the c-Si bare
cells can be significantly influenced by the measurement details such as the distance of the contact probes, position
of the contact bars and contact pressures. In this study, possible measurement errors due to these measurement details
are experimentally investigated by using different structures of bare cells and sample stages. It is shown that the
maximum power Pmax can be both overestimated or underestimated due to the distribution of the electric potential in
the bare cells, even when the contact probes are carefully positioned. Examples of the potential distribution along the
busbars of bare cells are demonstrated. Experimental correction procedure and formula are proposed, by which "true"
I-V curve can be calculated by the measured I-V curve and distribution of the electric potential.

description:   It is irrefutable that stock markets provide a barometer that can be relied upon to measure the economic condition of a country. As countries increasingly integrating, there is an urgent need for an ongoing and detailed study of the stock market. The stock market of a country plays a pivotal role in transferring funds from surplus units to deficit units. Any unfavourable news within the stock market may not only impact on market participants but also affect the entire economy. Hence, it is quite essential to recognise the factors that affect market favourably or unfavourably. The empirical literature has provided a set of exhaustive factors with either direct or indirect implications on the stock market. However, this research focusses on domestic Macroeconomic factors, which are projected through the application of the Arbitrage Pricing theory. The key macroeconomic drivers used for this research are Inflation, Interest rates, Treasury Bills, Money supply, GDP and stock returns. The study aims at reflecting upon the exogenous channels through which macroeconomic variables influence the stock market. The study seeks to investigate the relationship between the variables using econometric tests, like ARDL bound test, ARDL short-term and Long-term cointegration tests. Additionally, CUSUM test and Variance decomposition statistical tests were adopted to ensure the stability of the model and to make inferences on the causal relationship among the variables. The analysis began with first differencing the variables, and the results from the tests indicated that all the macroeconomic variables explain the variability in US stock returns in the long run except INDPRO. Whereas LM3 and INDPRO can only explain changes in Indian stock returns in the long term. Both stock markets exhibit the opposite relationship with their own domestic economic variables to some extent. In contrast, the variables behave differently in the short run, and so their relationship with stock returns varies. TB and CPI are the two variables that explain the variation in US stock returns in the short term. Whereas LM3 influences the India stock returns and the rest of the variables demonstrate a weak relationship with stock returns in the short run. The study further extends by investigating the stock returns volatility using ARCH & GARCH techniques which suggested the past stock returns influence the future period stock returns volatility for US and India as well as the results indicated that there is a relationship between the volatility of stock market returns and short-run deviations of the macroeconomic variables for both the countries.

description: Photovoltaic technology is quickly approaching grid parity, especially in southern Europe countries. In
this situation, with smaller feed in tariffs (both in terms of final price and quotas) and a rising price for electricity at
the consumer point, photovoltaics are emerging as an option for self-consumption. In the present work we explore the
possibilities of two PV façades made with a-Si modules. Both façades are placed on the R+D buildings at Soliker’s
factory, facing southwest. For one of then we have a full year of monitoring data. While southwest orientation is not
optimal for yearly energy production, it could be a good option for self-consumption depending on the building use
because of the different hourly and yearly electricity consumption profiles.

description: The establishment of viable minigrids for remote village electrification (RVE) faces a number of
structural barriers at the village level and at scale. These are interlinked such that solutions which address the village
level barriers can help resolve those at scale. Implementation models are therefore needed that directly address these
barriers and which are replicable, adaptable; and given the extent of energy poverty, are able to be readily
implemented at scale. The Bushlight India Project saw the development of an innovative implementation model for
off-grid RVE in India using renewable energy based village minigrids anchored by specially developed demand side
management (DSM) hardware. Developed in close collaboration with an integrated network of Indian grassroot
NGOs, RE Industry participants and government agencies, the Bushlight India Model is based on that used by the
successful Bushlight Project in Australia. One of the key innovations of the model is the Urja Bandhu, a simple, low
cost energy meter developed as part of the project, and the associated consultative Village Energy Planning process.
The Urja Bandhu limits the daily amount of energy individual consumers can access to their ‘daily energy budget’
negotiated during Village Energy Planning. This approach builds community ownership, provides residents a tool to
manage their energy, protects systems from overuse and allows systems to be designed that can reliably deliver
electricity to all consumers 24 hours a day, 7 days a week. With this, reliable financial models can be developed with
accurate projections of system revenue matched against costs over the life of the system.

description: Super Li-rich stars form a very small and enigmatic group whose existence cannot be explained in terms of the standard stellar evolution theory. The goal of our study is to check the reality of this group of cool giants based on an independent technique. We have carried out such a check using the K giant HD 77361 (HR 3597), which has previously been assigned to this rare type, as an example. We have redetermined the effective temperature Teff and surface gravity log g for this star. We have applied two different methods, photometric and spectroscopic, to estimate Teff (the accuracy of the Li-abundance determination depends significantly on this parameter). The value of log g has been found from the highly accurate parallax of this nearby star. To apply the photometric method of determining Teff, we have performed UBV observations of the star, which yielded V = 6.18 +/- 0.03, B - V = 1.13 +/- 0.01, and U - B = 1.18+/-0.05. The following parameters of the star have been found: effective temperature Teff = 4370+/- 100 K, surface gravity log g = 2.30 +/- 0.10, iron abundance log e(Fe) = 7.49 +/- 0.14, microturbulence Vt = 1.1 +/- 0.2 km/s, rotational velocity V sin i = 4.5 km/s, and mass M = 1.3 +/- 0.2 Msun. The lithium abundance has been determined from a non-LTE analysis of three Li I lines: the resonance line at 6707.8 ?A and the subordinate lines at 6103.6 and 8126.4 ?A (the latter in a blend with a CN molecular line). We have found a high lithium abundance, log e(Li) = 3.75 +/- 0.11, which exceeds considerably the initial abundance log e(Li) = 3.2 +/- 0.1 for young stars in the solar neighborhood. Thus, we have confirmed that the K giant HD 77361 actually belongs to the type of super Li-rich stars.

description: A great deal of research work has been undertaken in alpha-clustering study since the pioneering discovery of 12C+12C molecular resonances half a century ago. Our knowledge on physics of nuclear molecules has increased considerably and nuclear clustering remains one of the most fruitful domains of nuclear physics, facing some of the greatest challenges and opportunities in the years ahead. The occurrence of "exotic" shapes in light N=Z alpha-like nuclei is investigated. Various approaches of the superdeformed and hyperdeformed bands associated with quasimolecular resonant structures are presented. Evolution of clustering from stability to the drip-lines is examined: clustering aspects are, in particular, discussed for light exotic nuclei with large neutron excess such as neutron-rich Oxygen isotopes with their complete spectroscopy.

description: To assess the possibility of evacuating a building in case of a fire, a standard method consists in simulating the propagation of fire, using finite difference methods and takes into account the random behavior of the fire, so that the result of a simulation is non-deterministic. The mesh fineness tunes the quality of the numerical model, and its computational cost. Depending on the mesh fineness, one simulation can last anywhere from a few minutes to several weeks. In this article, we focus on predicting the behavior of the fire simulator at fine meshes, using cheaper results, at coarser meshes. In the literature of the design and analysis of computer experiments, such a problem is referred to as multi-fidelity prediction. Our contribution is to extend to the case of stochastic simulators the Bayesian multi-fidelity model proposed by Picheny and Ginsbourger (2013) and Tuo et al. (2014).

description: It is now well established that the homogenization of a periodic array of parallel dielectric fibers with suitably scaled high permittivity can lead to a (possibly) negative frequency-dependent effective permeability. However this result based on a two-dimensional approach holds merely in the case of linearly polarized magnetic fields, reducing thus its applications to infinite cylindrical obstacles. In this paper we consider a dielectric structure placed in a bounded domain of $\mathbb{R}^3$ and perform a full 3D asymptotic analysis. The main ingredient is a new averaging method for characterizing the bulk effective magnetic field in the vanishing-period limit. We evidence a vectorial spectral problem on the periodic cell which determines micro-resonances and encodes the oscillating behavior of the magnetic field from which artificial magnetism arises. At a macroscopic level we deduce an effective permeability tensor that we can be make explicit as a function of the frequency. As far as sign-changing permeability are sought after, we may foresee that periodic bulk dielectric inclusions could be an efficient alternative to the very popular metallic split-ring structure proposed by Pendry.

By exploiting such a kind of meter-sized telescope mount, we get a device which is both capable of compensating for the apparent rotation of the celestial sphere and the same design can be used independently from the actual geographical location. Our construction is the sole currently operating hexapod telescope mount performing dedicated optical imaging survey with a sub-arcsecond tracking precision.

description: We study 4-dimensional simply connected Lie groups $G$ with left-invariant Riemannian metric $g$ admitting non-trivial conformal Killing 2-forms. We show that either the real line defined by such a form is invariant under the group action, or the metric is half conformally flat. In the first case, the problem reduces to the study of invariant conformally Kähler structures, whereas in the second case, the Lie algebra of $G$ belongs (up to homothety) to a finite list of families of metric Lie algebras.

description: A multiscale numerical model based on nonequilibrium thermal effect for melting of metal powder bed subjected to constant heat flux is developed. The volume shrinkage due to density change is taken into account. The nonequilibrium model is discretized by an implicit finite difference method and solved numerically using an iterative tri-diagonal matrix algorithm. The evolutions of powder bed surface temperature and various interfacial locations as well as the melting temperature range during the melting process are investigated. The results show that liquid region, upper and lower parts of mushy zone are formed on the top of unsintered zone as the melting progresses. The duration of the preheating stage shortens and the melting rate accelerates as the initial porosity or initial temperature increases while particle size has much less effect on the melting process. The parametric study shows the melting temperature range of the powder bed widens with increasing initial porosity, decreasing initial temperature or increasing particle size.

description: NGC 7023 is a well-studied reflection nebula, which shows strong emission from polycyclic aromatic hydrocarbon (PAH) molecules in the form of aromatic infrared bands (AIBs). The spectral variations of the AIBs in this region are connected to the chemical evolution of the PAH molecules which, in turn, depends on the local physical conditions. We use the capabilities of SOFIA to observe a 3.2' x 3.4' region of NGC 7023 at wavelengths that we observe with high spatial resolution (2.7") at 3.3 and 11.2 um. We compare the SOFIA images with existing images of the PAH emission at 8.0 um (Spitzer), emission from evaporating very small grains (eVSG) extracted from Spitzer-IRS spectral cubes, the ERE (HST and CFHT), and H_2 (2.12 um). We create maps of the 11.2/3.3 um ratio to probe the morphology of the PAH size distribution and the 8.0/11.2 um ratio to probe the PAH ionization. We make use of an emission model and of vibrational spectra from the NASA Ames PAHdb to translate the 11.2/3.3 um ratio to PAH sizes. The 11.2/3.3 um map shows the smallest PAH concentrate on the PDR surface (H_2 and extended red emission) in the NW and South PDR. We estimated that PAHs in the NW PDR bear, on average, a number of carbon atoms (N_c) of ~70 in the PDR cavity and ~50 at the PDR surface. In the entire nebula, the results reveal a factor of 2 variation in the size of the PAH. We relate these size variations to several models for the evolution of the PAH families when they traverse from the molecular cloud to the PDR. The PAH size map enables us to follow the photochemical evolution of PAHs in NGC 7023. Small PAHs result from the photo-evaporation of VSGs as they reach the PDR surface. Inside the PDR cavity, the PAH abundance drops as the smallest PAH are broken down. The average PAH size increases in the cavity where only the largest species survive or are converted into C_60 by photochemical processing.

description: This paper is devoted to study cylindrically symmetric stellar filaments in self-interacting Brans-Dicke gravity. For this purpose, we construct polytropic filamentary models through generalized Lane-Emden equation in Newtonian regime. The resulting models depend upon the values of cosmological constant (due to scalar field) along with polytropic index and represent a generalization of the corresponding models in general relativity. We also investigate fragmentation of filaments by exploring the radial oscillations through stability analysis. This stability criteria depends only upon the adiabatic index.

Silicon Solar Cell Improvements

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1229-1234
description: Laser doping allows a highly localized phosphorus diffusion and offers many advantages of
realizing selective emitters on industrial scale in comparison to the conventional thermal diffusion methods. The
contactless formation of selective emitter with lower doped areas between the contact fingers and higher doped
areas beneath the front side metallization increases the efficiency  of silicon solar cells. In this study, the emitter
formation was achieved by two nano second pulsed lasers with different beam shapes at wavelength of 532 nm
patterning phosphorus doped phosphosilicate glass films as a doping source. Two different kinds of emitter
formation, a furnace phosphorus oxychloride and an inline spray-on process are characterized by electrochemical
capacity voltage, four-point-probe measurements and finally investigated in industrial solar cell process. The
internal quantum efficiency shows an improved response in the short wavelength region. An efficiency gain of 0.3% absolute using a shallow ~ 100 Ω/sq emitter and a laser doped selective emitter have been achieved on
multicrystalline silicon in an industrial feasible process.

description: In Switzerland in the end of the nineties several aesthetically attractive PV plants with special solar tiles
("Sunslates") were realised. Pictures of these plants were often shown as examples for a successful building integration of PV
plants. One of these plants with a peak power of 62.5 kWp was erected on the roof of the regional hospital in Burgdorf (RSE)
and commissioned in the end of 1999. For this plant the local utility granted a feed-in tariff of CHF 1 per kWh for 20 years.
The PV laboratory of BFH-TI in Burgdorf has registered since 1992 in the framework of long-term monitoring projects the
energy yield of all PV plants in Burgdorf [1]. Some of these plants are analytically monitored (with measurement of
irradiance into array plane, V and I on the DC side, AC power). At some other plants, among which also the PV plant at RSE,
due to the necessary investment or accessibility only the monthly energy yields received from the local utility are evaluated.
As the PV plant at RSE degraded seriously in course of time (see table 1), in a mandate for the local utility in summer 2010
the PV laboratory of BFH-TI has carried out several measurements at this plant. In this paper, the results of this degradation
and possible reasons for it are discussed.
Thermodynamics with fractal structure, Tsallis statistics and hadrons

description: A system presenting fractal structure in its thermodynamical functions is introduced, and it is shown that Tsallis statistics is the correct framework for describing the thermodynamical aspects of such fractal. Its Haussdorf dimension and its Lipshitz-Hölder exponent are determined in terms of the entropic index $q$. The connections with the intermittency in experimental data is discussed. The thermodynamical aspects of the thermofractal is related to the microscopic interaction of its components through the S-matrix.

Mapping the Current-Current Correlation Function Near a Quantum Critical Point

description: The current-current correlation function is a useful concept in the theory of electron transport in homogeneous solids. The finite-temperature conductivity tensor as well as Anderson's localization length can be computed entirely from this correlation function. Based on the critical behavior of these two physical quantities near the plateau-insulator or plateau-plateau transitions in the integer quantum Hall effect, we derive an asymptotic formula for the current-current correlation function, which enables us to make several theoretical predictions about its generic behavior. For the disordered Hofstadter model, we employ numerical simulations to map the current-current correlation function, obtain its asymptotic form near a critical point and confirm the theoretical predictions.

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 3080-3083
description: In recent years, CdTe PV has skyrocketed, and now represents almost 5% of the global PV market.
Besides being commercially successful, CdTe PV systems have also been shown to be characterized by overall sound
environmental performance by several cradle-to-gate retrospective and prospective life cycle studies. However, a
detailed LCA of the end-of-life stage of CdTe PV modules was found to be still lacking in the scientific literature.
The author performed one such study, based on the only decommissioning and recycling procedure that has been
tested on a full production scale so far. Results show that the adopted end-of-life strategy has considerable
environmental value in limiting the associated impacts to negligible levels. Also, a comparison was drawn between
the Cd emissions from the decommissioning of CdTe PV vs. the decommissioning of NiCd batteries, and CdTe PV
came out as the cleaner technology by far.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1349-1352
description: Selective emitter by etch back is an easy method to obtain a better blue response and lower contact
resistivity and therefore to improve the performance of a solar cell. To achieve a selective emitter with only one
diffusion step provides a cost reduction. In this work it is shown that it is possible to achieve a selective emitter
by etch back with commercial etching paste applied by screen printing. Both activation of the etching paste and
cleaning afterwards can be done with inline production equipment. Accurate alignment of the screen printed front
side grid is essential. The selective emitter cells show a big improvement in open circuit voltage and efficiency. It
is shown that the improvements are due to a better IQE and lower front side recombination.
