description: The heterojunction cell concept has become common in the field of solar cell research and development
due to their high efficiencies and their simple low-cost production process. Due to the temperature sensitivity of the
included intrinsic layer the curing process is limited to low temperatures. Because of their low-curing temperature, polymer
pastes are an excellent low temperature metallization solution. As shown in previous works [2-3], an inert curing atmosphere
can improve dramatically the paste and contact resistance of commercial available copper and silver based polymer
pastes. Hence, this work focuses on the development of an industrial inert inline drying system to improve the lowtemperature
metallization process. In further experiments, the verification of the industrial inert low temperature curing
process will be shown by cell efficiency of commercial polymer pastes on high efficiency heterojunction solar cells. In
this work it is shown that each paste has to be cured at its own optimized curing conditions to achieve the best cell efficiencies.
Therewith a cell efficiency of 19.96% could be reached with a commercial copper polymer paste.

description: We are reviewing the key features of a newly developed inline wet chemical tool. The system is especially designed for single side wet chemical processes like chemical edge isolation and chemical polishing. A new type of rollers transport system that is not immersed in the process medium is the key feature of the new system. The rollers are directly supplied with the chemical liquid which guarantees an efficient and permanent layer of etching solution for wafer processing. Because the wafers are not continuously contacted with the liquid the liquid overlap on the front side is reduced and there is less emitter damage on the front side and less etch marks at the wafer edge. The continuous supply of the liquid to the rollers results in a homogenously etched rear side.
One further improvement of the system is the location of the exhaust system that is continuously removing the reactive gases (NOx) that are emerging at the rear side of the wafer and thus avoiding the damage of the emitter by the gases on the front side. This is important for higher etch removals (>2μm) in single side etching or polishing where relatively high amounts of gases are generated that are efficiently removed in this new system.

Wissenschaftlich-künstlerischen Dissertation

description: Der ideale Publikationsworkflow richtet sich nach den Bedarfen der Publizierenden, der zu publizierenden Inhalte, der Fach-Community und der Infrastrukturen. Was aber, wenn die rasanten technischen Entwicklungen zu einer immer stärker wachsenden Diversität an Ausdrucksformen und Publikationsformaten führt und die Publikationsworkflows sich kaum oder garnicht innovativ entwickeln? Viele Abläufe im Bereich Open Access wurden aus dem Analogen ins Digitale übersetzt und fokussieren sich auf vorherrschenden, klassischen Veröffentlichungsformen. Die dominante Fixierung auf Text hemmt die Open Access-konforme Veröffentlichung von multimodalen und interaktiven Wissen. Wie geht man also vor, wenn es sich beim praktisch-künstlerische Forschungsteil einer Dissertation um ein interaktives Dokumentarfilmprojekt handelt, dass größtenteils unter freien Lizenzen im Netz steht? Am Beispiel der ersten wissenschaftlich-künstlerischen Dissertation, die an der Filmuniversität Babelsberg KONRAD WOLF verliehen wurde, zeigt der Vortrag die Herausforderungen, mit denen Autor*inInnen nicht genormter Publikationen in einem standardisierten Publikationsworkflow, wie dem des Promotionsverfahrens mit verpflichtender Veröffentlichung, konfrontiert sind. Besonders die User-Perspektive bietet wertvolle Einblicke in die Bedarfe der Publizierenden und verdeutlicht, weshalb das Open Access-Versprechen einem rapide anwachsenden Kreis an Scholars schon lange nicht mehr gerecht wird und diese zunehmend frustriert. Alles frei zugänglich, zum größten Teil unter freien Lizenzen. Was will man mehr? Aber sind alle Teile dieser Dissertation auffindbar, archiviert und zugänglich und das auch langfristig? Ist also die Bibliothek ihrer Aufgabe gerecht geworden? Anknüpfend an die Erfahrungen des Publizierenden beschreibt die UB der Filmuniversität Babelsberg KONRAD WOLF die Problematik des OA-Publizierens von künstlerischen Forschungsergebnissen hinsichtlich enger institutioneller Strukturen, nicht vorhandener Infrastrukturen, die die Workflowentwicklung erschweren. Das Fallbeispiel leitet zu der zentralen Frage über: Was bedeutet der oft enge Gestaltungsrahmen für die Veröffentlichungsform und welche Auswirkungen hat dies sowohl auf die Urheber*inInnen wie auch die veröffentlichenden Institutionen und deren Infrastrukturen? Welche Lösungsansätze braucht es auf welchen Ebenen, um Open-Access-Publikationsworkflows für text- wie nicht textbasierte Publikationen zu gestalten?

description: In this work, we present galaxy stellar and baryonic (stars plus cold gas) mass functions (SMF and BMF) and their halo mass dependence for two volume-limited data sets. The first, RESOLVE-B, coincides with the Stripe 82 footprint and is extremely complete down to baryonic mass Mbary ~ 10^9.1 Msun, probing the gas-rich dwarf regime below Mbary ~ 10^10 Msun. The second, ECO, covers a ~40 times larger volume (containing RESOLVE-A) and is complete to Mbary ~ 10^9.4 Msun. To construct the SMF and BMF we implement a new "cross-bin sampling" technique with Monte Carlo sampling from the full likelihood distributions of stellar or baryonic mass. Our SMFs exhibit the "plateau" feature starting below Mstar ~ 10^10 Msun that has been described in prior work. However, the BMF fills in this feature and rises as a straight power law below ~10^10 Msun, as gas-dominated galaxies become the majority of the population. Nonetheless, the low-mass slope of the BMF is not as steep as that of the theoretical dark matter halo MF. Moreover, we assign group halo masses by abundance matching, finding that the SMF and BMF separated into four physically motivated halo mass regimes reveal complex structure underlying the simple shape of the overall MFs. In particular, the satellite MFs are depressed below the central galaxy MF "humps" in groups with mass <10^13.5 Msun yet rise steeply in clusters. Our results suggest that satellite destruction and/or stripping are active from the point of nascent group formation. We show that the key role of groups in shaping MFs enables reconstruction of a given survey's SMF or BMF based on its group halo mass distribution.

description: The recent discovery of methyl formate and dimethyl ether in the gas phase of cold cores with temperatures as cold as 10 K challenges our previous astrochemical models concerning the formation of complex organic molecules. The strong correlation between the abundances and distributions of methyl formate and dimethyl ether further shows that current astrochemical models may be missing important chemical processes in cold astronomical sources. We investigate a scenario in which complex organic molecules and the methoxy radical can be formed on dust grains via a so-called "chain reaction" mechanism, in a similar manner to CO$_2$. A unified gas-grain microscopic-macroscopic Monte Carlo approach with both normal and interstitial sites for icy grain mantles is used to perform the chemical simulations. Reactive desorption with varying degrees of efficiency is included to enhance the non-thermal desorption of species formed on cold dust grains. In addition, varying degrees of efficiency for the surface formation of methoxy are also included. The observed abundances of a variety of organic molecules in cold cores can be reproduced in our models. The strong correlation between the abundances of methyl formate and dimethyl ether in cold cores can also be explained. Non-diffusive chemical reactions on dust grain surfaces may play a key role in the formation of some complex organic molecules.

description: Silicon heterojunction (SHJ) solar cells have potential to achieve high efficiencies. Among many process parameters, wafer quality plays an important role in determining the efficiency of a solar cell. The correlation between wafer quality and cell performance was investigated. The wafers in the top, middle, and bottom parts of each ingot were taken and tested. The results from JV-curve measurements revealed that the decreased efficiencies may be due to ambiguous and dark edges of cells shown in photoluminescence imaging, indicating low quality of wafers. After optimizing cell process with a fine quality of wafer, SHJ solar cell on a 6 inch n-mono wafer with a conversion efficiency of 23.43 % was achieved by AUO HJ-RD team.
Helioseismology: a fantastic tool to probe the interior of the Sun

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Helioseismology, the study of global solar oscillations, has proved to be an extremely powerful tool for the investigation of the internal structure and dynamics of the Sun. Studies of time changes in frequency observations of solar oscillations from helioseismology experiments on Earth and in space have shown, for example, that the Sun's shape varies over solar cycle timescales. In particular, far-reaching inferences about the Sun have been obtained by applying inversion techniques to observations of frequencies of oscillations. The results, so far, have shown that the solar structure is remarkably close to the predictions of the standard solar model and, recently, that the near-surface region can be probed with sufficiently high spatial resolution as to allow investigations of the equation of state and of the solar envelope helium abundance. The same helioseismic inversion methods can be applied to the rotational frequency splittings to deduce with high accuracy the internal rotation velocity of the Sun, as function of radius and latitude. This also allows us to study some global astrophysical properties of the Sun, such as the angular momentum, the grativational quadrupole moment and the effect of distortion induced on the surface (oblateness). The helioseismic approach and what we have learnt from it during the last decades about the interior of the Sun are reviewed here.

description: The GERDA experiment searches for neutrinoless double beta ($0νββ$) decay in $^{76}$Ge using an array of high purity germanium (HPGe) detectors immersed in liquid argon (LAr). Phase II of the experiment uses 30 new broad energy germanium (BEGe) detectors with superior pulse shape discrimination capabilities compared to the previously used semi-coaxial detector design. By far the largest background component for BEGe detectors in GERDA are n$^+$-surface events from $^{42}$K $β$ decays which are intrinsic in LAr. The $β$ particles with up to 3.5 MeV can traverse the 0.5 to 0.9 mm thick electrode and deposit energy within the region of interest for the $0νββ$ decay. However, those events have particular pulse shape features allowing for a strong discrimination. The understanding and simulation of this background, showing a reduction by up to a factor 145 with pulse shape discrimination alone, is presented in this work.

description: This paper presents solar cell modelling using single diode equivalent circuit as base line to train radial
basis functions neural network (RBFNN). The simulation was run using a random set of data (solar radiation and ambient
temperature) for the purpose to study the characteristics of solar cells at diffident situations. Afterwards, RBFNN has been
used to simulate the whole characteristics of solar cell in general and specifically at maximum power points (MPP).
Finally the RBFNN has been used to simulate a real data collected from Ramah site (East of Riyadh, Saudi Arabia). Two
sets of data have been prepared to train the RBFNN. It has been shown that RBFNN can predict the MPP with minimal
least mean square error (LMSE).
Stochastic Geometry Analysis of Multi-Antenna Two-Tier Cellular Networks

description: In this paper, we study the key properties of multi-antenna two-tier networks under different system configurations. Based on stochastic geometry, we derive the expressions and approximations for the users' average data rate. Through the more tractable approximations, the theoretical analysis can be greatly simplified. We find that the differences in density and transmit power between two tiers, together with range expansion bias significantly affect the users' data rate. Besides, for the purpose of area spectral efficiency (ASE) maximization, we find that the optimal number of active users for each tier is approximately fixed portion of the sum of the number of antennas plus one. Interestingly, the optimal settings are insensitive to different configurations between two tiers. Last but not the least, if the number of antennas of macro base stations (MBSs) is sufficiently larger than that of small cell base stations (SBSs), we find that range expansion will improve ASE.

description: In order to establish the n-type solar cells p-n junction, we have studied BBr3 diffusion in an open tube
furnace by varying parameters of the BBr3 diffusion process such as temperature, gas flows and durations of
individual process steps i.e. pre-deposition and drive-in. Then, output parameters such as carrier lifetime, sheet
resistance, and diffusion profile have been measured and statistically analyzed to optimize emitter characteristics. A
statistical analysis (factorial design) was finally employed to systematically explore the effects of a set of input
variables on the outputs. The interaction of inputs is also evaluated on every one of the outputs in which these effects
are also quantified using two level factorial method. Temperature and BBr3 flow were discovered to have the most
significant effect on different outputs such as carrier lifetime, junction depth, sheet resistance and final surface
concentration.

The contributions from beta decay and electron capture, pair annihilation, plasmon decay, and the photoneutrino process are modeled in detail, using updated tabulated nuclear rates. We also use realistic conditions of temperature, density, electron fraction and nuclear isotopic composition of the star from the state of the art stellar evolution code MESA. Results are presented for a set of progenitor stars with mass between 15 $M_\odot$ and 30 $M_\odot$. It is found that beta processes contribute substantially to the neutrino emissivity above realistic detection thresholds of few MeV, at selected positions and times in the evolution of the star.

description: The Death and Life of Great American Cities was written in 1961 and is now one of the most influential book in city planning. In it, Jane Jacobs proposed four conditions that promote life in a city. However, these conditions have not been empirically tested until recently. This is mainly because it is hard to collect data about "city life". The city of Seoul recently collected pedestrian activity through surveys at an unprecedented scale, with an effort spanning more than a decade, allowing researchers to conduct the first study successfully testing Jacobs's conditions. In this paper, we identify a valuable alternative to the lengthy and costly collection of activity survey data: mobile phone data. We extract human activity from such data, collect land use and socio-demographic information from the Italian Census and Open Street Map, and test the four conditions in six Italian cities. Although these cities are very different from the places for which Jacobs's conditions were spelled out (i.e., great American cities) and from the places in which they were recently tested (i.e., the Asian city of Seoul), we find those conditions to be indeed associated with urban life in Italy as well. Our methodology promises to have a great impact on urban studies, not least because, if replicated, it will make it possible to test Jacobs's theories at scale.

description: Scaling transistors' dimensions has been the thrust for the semiconductor industry in the last 4 decades. However, scaling channel lengths beyond 10 nm has become exceptionally challenging due to the direct tunneling between source and drain which degrades gate control, switching functionality, and worsens power dissipation. Fortunately, the emergence of novel classes of materials with exotic properties in recent times has opened up new avenues in device design. Here, we show that by using channel materials with an anisotropic effective mass, the channel can be scaled down to 1nm and still provide an excellent switching performance in both MOSFETs and TFETs. In the case of TFETs, a novel design has been proposed to take advantage of anisotropic mass in both ON- and OFF-state of the TFETs. Full-band atomistic quantum transport simulations of phosphorene nanoribbon MOSFETs and TFETs based on the new design have been performed as a proof.

description: To achieve high efficiency crystalline silicon solar cell, surface passivation is one of the most
important techniques. However, carrier lifetime at silicon substrate surface changes by electrode formation, in which
the formation process temperature is higher than deposition process of surface passivation. To clarify the mechanism
of this phenomenon, we investigated interface physical properties of the 18-nm thick SiN passivation film with and
without post deposition annealing by the combination of the conventional X-ray and hard-X-ray photoelectron
spectroscopies. A nitrogen rich silicon bonding structure near the interface of SiN/Si was observed, indicating that
oxygen impurities in the SiN film were induced as the interface transformation. These variations in the interlayer
properties led the deterioration of the passivation properties such as formation of interface states after the high
temperature annealing.

description: Coherent spatial transport or shuttling of a single electron spin through semiconductor nanostructures is an important ingredient in many spintronic and quantum computing applications. In this work we analyze the possible errors in solid-state quantum computation due to leakage in transporting a single-spin qubit through a semiconductor double quantum dot. In particular, we consider three possible sources of leakage errors associated with such transport: finite ramping times, spin-dependent tunneling rates between quantum dots induced by finite spin-orbit couplings, and the presence of multiple valley states. In each case we present quantitative estimates of the leakage errors, and discuss how they can be minimized. Moreover, we show that in order to minimize leakage errors induced by spin-dependent tunnelings, it is necessary to apply pulses to perform certain carefully designed spin rotations. We further develop a formalism that allows one to systematically derive constraints on the pulse shapes and present a few examples to highlight the advantage of such an approach.

description: As an unusual type of anomalous diffusion behavior, (transient) superballistic transport is not well understood but it has been experimentally observed recently. We here calculate the white noise effect (in Markov approximation) on the quantum diffusion in 1D tight-binding model with disordered and quasi-periodic region of size L attached to perfect lattices at both ends. Here we show the effect of white noise on spreading of the wave packet initially located at the center of the sublattice. We find threshold values of the white noise strength, beyond which the quantum hyperdiffusion does not occur. We predict from our numerical studies that the quantum hyperdiffusion exponent can be tuned by the strength of applied white noise. Therefore we can manually apply noise to a system to drive it to desired diffusion rate.

description: Metal wrap through (MWT) cells and modules offer technology that combines a front junction cell with an all back contact module interconnection offering potential for higher efficiency, improved cost to power ratio, lower electrical cell to module losses, and improved module aesthetics. For the best conversion efficiency, isolation of the vias for the emitter contacts is key to reduce shunting pathways. However, in reverse bias conditions, the vias are also a controlled current pathway for homogenous dissipation of heat, offering new design opportunities for diode free, shade tolerant modules. We have developed a process for via isolation in high efficiency n-MWT cells where the behavior under reverse bias can be tuned with little impact on illuminated I-V curve and efficiency. We find that after the first exposure to reverse bias, the efficiency of these cells stabilizes and further reverse bias soaking or testing has little impact on performance. Further, these cells were processed into single cell laminates for simulated hot spot testing. The laminates with the highest reverse current performed best under all shading conditions (20%-100%) and were in fact the only laminates that survived all shading conditions without breakage, hot spot development, or significant conversion efficiency reduction.

description: Rotational temperatures Trot derived from lines of the same OH band are an important method to study the mesopause region near 87 km. To measure realistic temperatures, the rotational level populations have to be in local thermodynamic equilibrium (LTE). However, this might not be fulfilled, especially at high emission altitudes. In order to quantify possible non-LTE contributions to the OH Trot as a function of the upper vibrational level v', we studied a sample of 343 echelle spectra taken with the X-shooter spectrograph at the Very Large Telescope at Cerro Paranal in Chile. These data allowed us to analyse 25 OH bands in each spectrum. Moreover, we could measure lines of O2b(0-1), which peaks at 94 to 95 km, and O2a(0-0) with an emission peak at about 90 km. Since the radiative lifetimes are relatively long, the derived O2 Trot are not significantly affected by non-LTE contributions. For a comparison with OH, the differences in the emission profiles were corrected by using OH emission, O2a(0-0) emission, and CO2-based temperature profile data from the multi-channel radiometer SABER on the TIMED satellite. For a reference profile at 90 km, we found a good agreement of the O2 with the SABER-related temperatures, whereas the OH temperatures, especially for the high and even v', showed significant excesses with a maximum of more than 10 K for v' = 8. We could also find a nocturnal trend towards higher non-LTE effects, particularly for high v'.

description: This paper presents 2D simulation study of back contacted heterojunction solar cell with inserted
highly doped crystalline silicon buffer layer at the emitter interface, forming hetero-homojunction concept. It is
shown that by optimization of the buffer layer it is possible to achieve field effect passivation, thus lower
sensitivity of the output performance on the defect states and band alignment at the amorphous/crystalline silicon
heterointerface. Comparison study of hetero-homojunction solar cells based on n-type and p-type silicon substrate
revealed two main advantages for solar cells with n-type silicon substrate; i) higher attainable efficiency and ii)
more straightforward design of back contact arrangement, which can be optimized independently from
optimization of buffer layer.
Photon reflection by a quantum mirror: a wave function approach

description: We derive from first principles the momentum exchange between a photon and a quantum mirror upon reflection, by considering the boundary conditions imposed by the mirror surface on the photon wave equation. We show that the system generally ends up in an entangled state, unless the mirror position uncertainty is much smaller than the photon wavelength, when the mirror behaves classically. Our treatment leads us directly to the conclusion that the photon momentum has the known value hk/2π. This implies that when the mirror is immersed in a dielectric medium the photon radiation pressure is proportional to the medium refractive index n. Our work thus contributes to the longstanding Abraham-Minkowski debate about the momentum of light in a medium. We interpret the result by associating the Minkowski momentum (which is proportional to n) with the canonical momentum of light, which appears naturally in quantum formulations.

micro-enterprises

description: The idea that a person can do the same job for 40 years, is outdated. In this rapidly changing world, the right to lifelong learning is becoming increasingly important. However, not everyone gets equal opportunities for lifelong learning. With this research, I aim to accumulate knowledge on how regulations can reach vulnerable target groups, in particular workers in micro-enterprises.. As existing research is limited to socio-economic or psychological perspectives, the legal delineation of the right to lifelong learning and the interaction (in the form of conflict or cooperation) between different policy levels is unknown territory. This research considers the impact of the international right to lifelong learning on the national legal framework and subsequently examines the existing legal framework, thresholds and possible regulatory adjustments. The regulation is examined from the bottom-up perspective of a micro-enterprise. Through case study research in three selected sectors that score poorly on training rates, three main areas of regulatory tension are studied: international & national, national & regional, sectoral & individual. The research will not only contain qualitative legal research, but by using semi-structured expert interviews and the vignette method, experiences with the application of the right to lifelong learning in practice will also be included.

description: When mathematical/computational problems reach infinity, extending analysis and/or numerical computation beyond it becomes a notorious challenge. We suggest that, upon suitable singular transformations (that can in principle be computationally detected on the fly) it becomes possible to go beyond infinity to the other side, with the solution becoming again well behaved and the computations continuing normally. In our lumped, Ordinary Differential Equation (ODE) examples this infinity crossing can happen instantaneously; at the spatially distributed, Partial Differential Equation (PDE) level the crossing of infinity may even persist for finite time, necessitating the introduction of conceptual (and computational) buffer zones in which an appropriate singular transformation is continuously (locally) detected and performed. These observations (and associated tools) could set the stage for a systematic approach to bypassing infinity (and thus going beyond it) in a broader range of evolution equations; they also hold the promise of meaningfully and seamlessly performing the relevant computations. Along the path of our analysis, we present a regularization process via complexification and explore its impact on the dynamics; we also discuss a set of compactification transformations and their intuitive implications.

description: The search of extragalactic regions with conspicuous presence of Wolf-Rayet (WR) stars outside the Local Group is challenging task due to the difficulties in detecting their faint spectral features. In this exploratory work, we develop a methodology to perform an automated search of WR signatures through a pixel-by-pixel analysis of integral field spectroscopy (IFS) data belonging to the Calar Alto Legacy Integral Field Area survey, CALIFA. This technique allowed us to build the first catalogue of Wolf-Rayet rich regions with spatially-resolved information, allowing to study the properties of these complexes in a 2D context. The detection technique is based on the identification of the blue WR bump (around He II 4686 Å, mainly associated to nitrogen-rich WR stars, WN) and the red WR bump (around C IV 5808 Å and associated to carbon-rich WR stars, WC) using a pixel-by-pixel analysis. We identified 44 WR-rich regions with blue bumps distributed in 25 galaxies of a total of 558. The red WR bump was identified only in 5 of those regions. We found that the majority of the galaxies hosting WR populations in our sample are involved in some kind of interaction process. Half of the host galaxies share some properties with gamma-ray burst (GRB) hosts where WR stars, as potential candidates to being the progenitors of GRBs, are found. We also compared the WR properties derived from the CALIFA data with stellar population synthesis models, and confirm that simple star models are generally not able to reproduce the observations. We conclude that other effects, such as the binary star channel (which could extend the WR phase up to 10 Myr), fast rotation or other physical processes that causes the loss of observed Lyman continuum photons, are very likely affecting the derived WR properties, and hence should be considered when modelling the evolution of massive stars.

description: We report on the impact of the optical constant uncertainty on quasi-steady-state (QSS) mode measured -effective
minority carrier lifetime of silicon wafers using the Sinton WCT-120 lifetime tester. The optical constant enables
evaluating the total carrier generation within the wafer and can be estimated by comparing the optical properties of the
wafer and those of the reference cell of the lifetime tester. We establish that for chemically treated silicon surface an
accurate knowledge of external and internal wafer properties is required to perfectly determine the generation rate.
