description: Despite numerous attempts, no exomoon has firmly been confirmed to date. New missions like CHEOPS aim to characterize previously detected exoplanets, and potentially to discover exomoons. In order to optimize search strategies, we need to determine those planets which are the most likely to host moons. We investigate the tidal evolution of hypothetical moon orbits in systems consisting of a star, one planet and one test moon. We study a few specific cases with ten billion years integration time where the evolution of moon orbits follows one of these three scenarios: (1) "locking", in which the moon has a stable orbit on a long time scale ($\gtrsim$ 10$^9$ years); (2) "escape scenario" where the moon leaves the planet's gravitational domain; and (3) "disruption scenario", in which the moon migrates inwards until it reaches the Roche lobe and becomes disrupted by strong tidal forces. Applying the model to real cases from an exoplanet catalogue, we study the long-term stability of moon orbits around known exoplanets. We calculate the survival rate which is the fraction of the investigated cases when the moon survived around the planet for the full integration time (which is the age of the star, or if not known, then the age of the Sun).The most important factor determining the long term survival of an exomoon is the orbital period of the planet. For the majority of the close-in planets (<10 days orbital periods) there is no stable orbit for moons. Between 10 and 300 days we find a transition in survival rate from about zero to 70\%. Our results give a possible explanation to the lack of successful exomoon discoveries for close-in planets. Tidal instability causes moons to escape or being tidally disrupted around close-in planets which are mostly favoured by current detection techniques.

description: An experiment measuring electroproduction of hypernuclei has been performed in Hall A at Jefferson Lab on a $^{12}$C target. In order to increase counting rates and provide unambiguous kaon identification two superconducting septum magnets and a Ring Imaging CHerenkov detector (RICH) were added to the Hall A standard equipment. An unprecedented energy resolution of less than 700 keV FWHM has been achieved. Thus, the observed \lam{12}{B} spectrum shows for the first time identifiable strength in the core-excited region between the ground-state {\it s}-wave $Λ$ peak and the 11 MeV {\it p}-wave $Λ$ peak.

description: Prospective validation of risk models is needed to assess their clinical utility, particularly over the longer term. We evaluated the performance of six commonly used breast cancer risk models (IBIS, BOADICEA, BRCAPRO, BRCAPRO-BCRAT, BCRAT, and iCARE-lit). 15-year risk scores were estimated using lifestyle factors and family history measures from 7608 women in the Melbourne Collaborative Cohort Study who were aged 50-65 years and unaffected at commencement of follow-up two (conducted in 2003-2007), of whom 351 subsequently developed breast cancer. Risk discrimination was assessed using the C-statistic and calibration using the expected/observed number of incident cases across the spectrum of risk by age group (50-54, 55-59, 60-65 years) and family history of breast cancer. C-statistics were higher for BOADICEA (0.59, 95% confidence interval (CI) 0.56-0.62) and IBIS (0.57, 95% CI 0.54-0.61) than the other models (p-difference ≤ 0.04). No model except BOADICEA calibrated well across the spectrum of 15-year risk (p-value < 0.03). The performance of BOADICEA and IBIS was similar across age groups and for women with or without a family history. For middle-aged Australian women, BOADICEA and IBIS had the highest discriminatory accuracy of the six risk models, but apart from BOADICEA, no model was well-calibrated across the risk spectrum.

description: Inward migration of giant planets is predicted by hydrodynamical simulations during the gas phase of the protoplanetary disc. The phenomenon is also invoked to explain resonant and near-resonant exoplanetary system structures. The early inward migration may also have affected our Solar System and sculpted its different minor planet reservoirs. In this study we explore how the early inward migration of the giant planets shapes the Kuiper Belt. We test different scenarios with only Neptune and Uranus and with all the four giant planets, including also some models with the subsequent outward planetesimal-driven migration of Neptune after the gas dispersal. We find objects populating mean motion resonances even when Neptune and Uranus do not migrate at all or only migrate inwards. When the planets are fixed, planetesimals stick only temporarily to the mean motion resonances, while inwards migration yields a new channel to populate the resonances without invoking convergent migration. In these cases, however, it is hard to populate mean motion resonances that do not cross the planetesimal disc (such as 2:1 and 5:2) and there is a lack of resonant KBOs that cross Neptune's orbit. These Neptune crossers are an unambiguous signature of the outward migration of Neptune. The starting position and the growth rate of Neptune matters for the contamination of the classical Kuiper belt region from neighbouring regions. The eccentricity and inclination space of the hot classicals and the scattered disc region become much more populated when all the giant planets are included. The 5:2 resonance with Neptune becomes increasingly populated with deeper inward migrations of Neptune. The overall inclination distribution, however, is still narrower than from observations, as is generally the case for Kuiper belt population models.

description: During organ development, tubular organs often form from flat epithelial primordia. In the placodes of the forming tubes of the salivary glands in the Drosophila embryo, we previously identified spatially defined cell behaviors of cell wedging, tilting, and cell intercalation that are key to the initial stages of tube formation. Here, we address what the requirements are that ensure the continuous formation of a narrow symmetrical tube from an initially asymmetrical primordium whilst overall tissue geometry is constantly changing. We are using live-imaging and quantitative methods to compare wild-type placodes and mutants that either show disrupted cell behaviors or an initial symmetrical placode organization, with both resulting in severe impairment of the invagination. We find that early transcriptional patterning of key morphogenetic transcription factors drives the selective activation of downstream morphogenetic modules, such as GPCR signaling that activates apical-medial actomyosin activity to drive cell wedging at the future asymmetrically placed invagination point. Over time, transcription of key factors expands across the rest of the placode and cells switch their behavior from predominantly intercalating to predominantly apically constricting as their position approaches the invagination pit. Misplacement or enlargement of the initial invagination pit leads to early problems in cell behaviors that eventually result in a defective organ shape. Our work illustrates that the dynamic patterning of the expression of transcription factors and downstream morphogenetic effectors ensures positionally fixed areas of cell behavior with regards to the invagination point. This patterning in combination with the asymmetric geometrical setup ensures functional organ formation.

Scale Norming

description: Scale norming is where respondents use qualitatively different scales to answer the same question across survey waves. It makes responses challenging to compare intertemporally or interpersonally. This paper develops a formal model of the cognitive process that could give rise to scale norming in year on year responses to life satisfaction scale questions. It then uses this model to conceptually differentiate scale norming from adaptation and changes in reference points. Scale norming could make life satisfaction responses misleading with regards to the changing welfare of individuals. In particular, individuals who would say that their life is "improving" or "going well" might nonetheless give the same scale response year after year. This has negative implications for the use of scales in cost-benefit analysis and other welfarist applications. While there is already substantial empirical evidence for the existence of scale norming, its implications for welfare analysis are sometimes understated on the grounds that this evidence might simply be the product of errors of memory. The paper presents new empirical evidence for scale norming from two surveys (N1 = 278; N2 = 1050) designed such that errors of memory are an unconvincing explanation for the results.

description: Innovative bonding technology is key for system integration of photovoltaic modules in façade and
roofing systems. The technology transfer from established bonding solutions such as façade and roofing systems
allows combining aesthetic appearance, functionality such as weather protection, shading, insulation and the
functional benefits of PV-modules as part of a building envelope. Building integrated PV (BIPV) requires specific
approaches regarding design and evaluation. To guarantee a reliable construction over decades, different standards of
structural bonding have to be considered and combined reasonably with the existing PV standards.
Prefabricated modules, innovative mounting systems and efficient manufacturing processes allow cost savings and
could partly compensate the immanent disadvantages of BIPV such as vertical module orientation in comparison to
“classic” non-integrated rooftop systems.

description: Commercially available quantum dots, encapsulated in a PMMA film were used as a luminescent
down-shifting layer on CdS/CdTe photovoltaic devices. The application of these films resulted in the improvement of
the short-circuit current by over 5%. Additionally, the contribution to total photocurrent generated from the short
wavelength (≤500nm) part of the solar spectrum was increased by over 130%. The films have been shown to
reduce the amount of light lost at  = ≥550nm due to masking or scribing on the device by scattering the light onto
the contact. At shorter wavelengths ( = ≤500nm) the isotropic emission of light achieves a similarn effect. This
scattering sevres to increase the optical area of the contact. The efficiency gains shown in this paper are comparable
to those shown by phosphors with scope for improvement as quantum dot luminescent quantum yields increase.

description: The field of hybrid photovoltaic devices has become increasingly attractive due to the potential advantages of using
organic and inorganic semiconductors combined. However, many challenges remain, especially in the development
of optimized inorganic materials for optoelectronic applications. In this work, we carefully design an inorganic titania
nanoframework with highly accessible mesochannels, ordered pores and crystalline walls onto a transparent
conductive oxide (ITO, Indium Tin Oxide). We introduce a thin dense titania layer to modify the ITO surface,
followed by the sol-gel deposition of the mesoporous titania that is further exposed to thermal treatment. The
inorganic structure is studied by several techniques like electronic microscopy, X-ray diffraction and environmental
ellipsometric porosimetry (EEP). An organic material is later impregnated into the nanostructure from its solution.
The device is completed with the vapor evaporation of a metal that acts as the back contact. This work constitutes an
early approach to the understanding of novel materials for new solar technologies. The focus here is based on the
optimization of the inorganic semiconductor but further optimization of the organic material is required for good
performance of the solar cells.

description: For achieving a monolithic series connection of cells in a Cu(In,Ga)Se2 thin film module, in most cases
a combination of laser scribing and mechanical scribing steps is used. Interruptions in these scribing processes can
severely deteriorate the module efficiency. In this work we investigate the use of spatially resolved
electroluminescence (EL) images for identifying and characterizing such scribing defects. Electroluminescence
imaging allows determining local junction-voltage differences within a solar cell, and thus is sensitive to scribing
defects. Furthermore, EL imaging is fast allowing its use as an inline metrology tool. In this work we use a
simulation tool based on the network simulation method to simulate the local junction voltage variations within cells
in a module. Using this simulation tool we determine EL image signatures of various types of scribing defects, which
can be used to identify real scribing defects. We investigate defective scribing lines through the molybdenum back
contact, the CIGS absorber and the transparent conductive oxide. In order to verify our simulations we
experimentally implement scribing interruptions of varying lengths and record EL images of the defects. We find the
simulations and experiments are in good agreement.

description: This paper describes the implementation of standard IEC 61853 - Part 1 [1] at the European Solar Test
Installation (ESTI). The purpose of this work is to assess the reproducibility of the power matrix measurements
obtained by the three methods specified in that standard, namely: under natural sunlight using a tracking system;
under natural sunlight without tracker; using a Large Area Pulsed Solar Simulator of Class AAA. Three module
technologies (poly-Si, CdTe and CIS) were characterized according to the IEC standard.
The present work also includes a procedure based on un-calibrated mesh filters compared to other techniques
available at ESTI to reduce the irradiance intensity using indoor apparatus. The advantage is that mesh filters can be
mounted outdoor as well as indoor allowing direct comparison of measurement results.
All three methods as implemented at ESTI agree well for irradiances at and above 400 W/m2. With the additional use
of a calibrated self-reference variant, applied to solve issues of uniformity and spectral changes [2], good agreement
was found for all irradiances for all three module technologies studied.
These aspects have been studied to improve the mesh filtering procedure and to evaluate its introduction in the
ISO 17025 Quality System of ESTI.

description: This paper describes a novel Cu paste for low temperature sintering, which can be compatible to
hetero-junction solar cell to require low temperature process (<200 ºC). To this end, Cu alloy pastes containing a low
melting point alloy ((LMPA) were prepared. The paste sintered typically below 200 ºC showed competitive line and
contact resistivities against a Ag resin paste. The SEM and TEM images of the cross section of sintered paste
revealed that the LMPA covered over Cu particles and filled the space between Cu particles and the interface with the
substrate after it melted. Oxidation of metallized Cu was investigated by XPS depth-profile measurements, indicating
that no significant oxidation of Cu occurred while some oxidation of LMPA was sacrificed. For Cu migration into Si
substrate, preliminary experiments using dynamic SIMS shows that it was within the detection limit after heating
metallized Cu paste on Si at 230 ºC for 1 h. We concluded that LMPA coated on Cu might serve as a barrier layer to
inhibit the migration into Si.

description: The investigation of the electronic properties of semiconductors is inherently challenging due to the ensemble averaging of fundamentals to transport measurements (i.e., resistivity, Hall, and Seebeck coefficient measurements). Here, we investigate the incorporation of a fourth measurement of electronic transport, the Nernst coefficient, into the analysis, termed the method of four-coefficients. This approach yields the Fermi level, effective mass, scattering exponent, and relaxation time. We begin with a review of the underlying mathematics and investigate the mapping between the four-dimensional material property and transport coefficient spaces. We then investigate how the traditional single parabolic band method yields a single, potentially incorrect point on the solution sub-space. This uncertainty can be resolved through Nernst coefficient measurements and we map the span of the ensuing sub-space. We conclude with an investigation of how sensitive the analysis of transport coefficients is to experimental error for different sample types.

description: The first experiences with potential induced degradation (PID) of silicon solar cells have been presented in
literature since 1989 [1-4]. It has been shown that PID may cause power losses of more than 30% for modules out in the field.
Critical issues on the cell level are the SiNx anti-reflective coatings (ARC), their deposition method, the emitter thickness and
metallization (thus influencing the electrical series resistance). The leakage current was found as an indicator for the intensity
of degradation. Moreover, different test methods to prove the stability or susceptibility of samples have been presented.
In this paper we are showing the influence of the anti-reflection coating to provoke PID and the ability of silicon nitrite layers
to prevent PID. For each layer structure, at least four different designs have been manufactured and tested for their stability
against PID. To do so, it was necessary to find an appropriate test sequence, which would show polarization effects in an
adequate time frame, while there is no standard procedure available that addresses this problem for the time being.
Furthermore, it has been necessary to develop suitable reference samples to compare the results and to prove the repeatability
of the test sequences. The experiment has been divided into two parts: The pre-evaluation has been realized with small onecell
mini-modules to probe the adequate testing parameters and to analyze the leakage currents for various prone samples.
During the second part, we also investigated the reversibility of PID - depending on the state of degradation of these samples
- to check whether PID is one 100% reversible, or whether the degradation mechanism also shows an irreversible part.

description: In this paper, comparative study of plasmonic effect of silver nanoparticles (Ag NPs) sandwiched between Si3N4 and SiO2 structures on c-Si photoactive absorbing material is presented. For comparative study, four different types of architectures were prepared. Si3N4 and SiO2 layers were deposited by inductively coupled plasma chemical vapour deposition (ICPCVD) method. Silver nanoparticles were successfully fabricated by RF sputtering of Ag film followed by a rapid thermal anneal (RTP) in Ar gas atmosphere at 400 0C for 60 seconds only which means very less process time for nanoparticles fabrication. The proposed architectures were studied for their applicability in standard wafer based c-Si solar cells with the motivations to avoid texturization. It is shown that absorption (reduced reflection) near bandgap of Si can be enhanced using the architecture in which Ag NPs are fabricated on silicon nitride surface and the silicon oxide layer should be the top most layer to have better combined plasmonic and ARC
effect. Also the observed results suggest that having nanoparticles of large sizes and high surface coverage on the
front surface as in this case, results in higher reflection in visible wavelength region though it shows comparatively
less reflection at larger wavelength which suggests the requirement of Ag NP’s with much lesser surface coverage
and uniform distribution over the front surface. In addition, the impact of degradation on plasmonic property of Ag
NP’s due to exposure in atmospheric ambient for long time have also been analysed. The observation strongly
recommends the requirement of passivation of Ag NP’s with a layer like SiO2 to avoid reaction from outside
environment.

We find that the fidelity is able to signal quantum phase transitions between the Luttinger liquid phase, the density-wave phase, and the phase separation state of the system; and the concurrence can be used to signal the transition between the density-wave phase and the Ising phase.

description: In dieser Arbeit wird eine Methode zur strukturierten Validierung von Batteriezellkühlungen aus querumströmten, kleinformatigen, zylindrischen Batteriezellen über mehrere Entwicklungsgenerationen des Batteriemoduls erarbeitet. Auf Basis des aktuellen Forschungsstandes werden Kriterien erarbeitet, um die Eignung virtueller, physischer und gemischt physisch-virtueller Modelle für die Validierung in der frühen Entwicklungsphase zur Unterstützung des Frontloadings zu bewerten. Neben einfachen virtuellen zeigen gemischt physisch-virtuelle Modellansätze das Potential zur Unterstützung in der frühen Phase. Die im Rahmen der Arbeit erarbeitete Methode strukturiert die Batteriemodulentwicklung in fünf Entwicklungsgenerationen. Bei den Entwicklungsgenerationen handelt es sich um virtuelle, physische und gemischt physisch-virtuelle Modelle im Sinne des IPEK-X-in-the-Loop-Ansatzes. Die gemischt physisch-virtuelle Modellbildung kommt dabei in zwei Entwicklungsgenerationen zum Einsatz. Die Arbeit beschreibt den Aufbau dieser zwei Validierungsumgebungen und deren Anwendung in der jeweiligen Entwicklungsgeneration. Die erste Validierungsumgebung nutzt drei physische Batteriezellen, die thermisch und elektrisch mit einer Echtzeitsimulation des zu entwickelnden Batteriemoduls gekoppelt sind, um das thermisch transiente Verhalten des Batteriemoduls nachzubilden. Die zweite, gemischt modellierte Validierungsumgebung besteht aus thermischen Ersatzbatteriezellen mit steuerbarer Heizleistung und einem modularen physischen Prüfaufbau, der die Batteriezellkühlung vollständig abbildet. Die beschriebene Methode wird an zwei Entwicklungsbeispielen erprobt, bei welchen Zellen des Formats 18650 mit Kühlflüssigkeit querumströmt werden. Im ersten Entwicklungsbeispiel werden alle Entwicklungsgenerationen bis auf jene durchlaufen, die über drei physische Zellen das thermischen Verhalten des Batteriemoduls approximiert. Diese Entwicklungsgeneration wird im zweiten Entwicklungsbeispiel aufgrund der Möglichkeit, thermisch transiente Vorgänge abzubilden, angewendet. Die anhand der erarbeiteten Kriterien abschließende Evaluation der Methode über die Entwicklungsbeispiele bestätigt die Unterstützung des Frontloadings in der frühen Phase der Entwicklung von Batteriezellkühlungen.

description: Ageing is associated with increased vulnerability to environmental cold exposure. Previously, we identified the role of the cold-sensitive transient receptor potential (TRP) A1, M8 receptors as vascular cold sensors in mouse skin. We hypothesised that this dynamic cold-sensor system may become dysfunctional in ageing. We show that behavioural and vascular responses to skin local environmental cooling are impaired with even moderate ageing, with reduced TRPM8 gene/protein expression especially. Pharmacological blockade of the residual TRPA1/TRPM8 component substantially diminished the response in aged, compared with young mice. This implies the reliance of the already reduced cold-induced vascular response in ageing mice on remaining TRP receptor activity. Moreover, sympathetic-induced vasoconstriction was reduced with downregulation of the α2c adrenoceptor expression in ageing. The cold-induced vascular response is important for sensing cold and retaining body heat and health. These findings reveal that cold sensors, essential for this neurovascular pathway, decline as ageing onsets.

description: In this paper, the successful introduction of an Al2O3 passivation layer in an industrial type PERC process flow is described. The thin Al2O3 layers are deposited in a high throughput inline atomic layer deposition (ALD) system and capped with a thick additional SiOx/SiNx layer. An outgassing step was performed to improve layer quality and to avoid blister formation. An increasing trend in Voc and Isc was observed with increasing temperature with maximum values of 642mV and 38mA/cm2 respectively. Despite a non-optimized laser ablation resulting in low fill factors, a best cell performance of 18.5% could be reached.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1991-1995
description: The encapsulation method of crystalline silicon modules plays an important role in the mitigation of
potential induced degradation (PID) on module level. The focus on this work is to identify possibilities of mitigating
PID for selective emitter cell technologies by the means of new module designs without the necessity of cell level
modifications.
In this paper we present different frontcover and encapsulation materials, which have been tested in different module
layouts. We predominantly examined innovative laminate configurations allowing for higher transmission rates in the
UV range and thus increasing short circuit currents (ISC) of selective emitter cells. We examined these performance
(PMPP) enhancements consisting in higher optical transmission in relation to its resistance against PID. As a result of
this assessment we show new module designs, which are both capable to improve module efficiencies while avoiding
PID effects. Furthermore, different EVAs have been tested regarding their PID .

description: We study the group velocities of electronic states and distributions of currents in $α-\mathcal{T}_3$ lattice ribbons under a uniform perpendicular magnetic field. Using the effective low-energy model we analyze all possible simple configurations of lattice termination with zigzag and armchair boundaries. We show that the edge current depends on the type of zigzag termination, and can be zero or finite near the edge. Also similar dependence is observed in the case of armchair termination and is related to the size of the ribbon. The nonzero current flowing along the edge can be used a signature of formation of propagating edge states. Also we show the qualitative difference in the distribution of the edge current between the case of $α=1$ (dice model) and other values of model parameter $α\neq 1$ for armchair-terminated ribbons.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1394-1397
description: The present work is related to effects originating from the spatial character and therefore referring to the distributed resistance of a silicon solar cell. Two effects are regarded: Firstly, the bending of the illuminated IVcurve particular at open-circuit-conditions towards a lower voltage due to an increased metal/emitter resistance.
Secondly, enhanced fill factor losses due to lateral current paths in case of back contact solar cells. A simple approach is presented by taking into account a second one-diode-model in addition to a conventional standalone one-diodemodel. The key idea is simple: By separating these models by a resistor, diodes are forward biased differently as it is the case in real operation conditions and internal current flow leads to a distortion of the measurable global IV-curve. We show that results achieved by the so called “distributed-two-diode-model” give already comparable results to far more complex two-dimensional finite element simulations utilizing Sentaurus TCAD.

description: Cells replicate and segregate their DNA with precision. Previous studies showed that these regulated cell-cycle processes were present in the last eukaryotic common ancestor and that their core molecular parts are conserved across eukaryotes. However, some metamonad parasites have secondarily lost components of the DNA processing and segregation apparatuses. To clarify the evolutionary history of these systems in these unusual eukaryotes, we generated a genome assembly for the free-living metamonad Carpediemonas membranifera and carried out a comparative genomics analysis. Here, we show that parasitic and free-living metamonads harbor an incomplete set of proteins for processing and segregating DNA. Unexpectedly, Carpediemonas species are further streamlined, lacking the origin recognition complex, Cdc6 and most structural kinetochore subunits. Carpediemonas species are thus the first known eukaryotes that appear to lack this suite of conserved complexes, suggesting that they likely rely on yet-to-be-discovered or alternative mechanisms to carry out these fundamental processes.

description: In order to face the complexity of business environments and detect priorities while triggering contingency strategies, we propose a new methodological approach that combines text mining, social network and big data analytics, with the assessment of stakeholders' attitudes towards company core values. This approach was applied in a case study where we considered the Twitter discourse about core values in Italy. We collected more than 94,000 tweets related to the core values of the firms listed in Fortune's ranking of the World's Most Admired Companies (2013-2017). For the Italian scenario, we found three predominant core values orientations (Customers, Employees and Excellence) - which should be at the basis of any business strategy - and three latent ones (Economic-Financial Growth, Citizenship and Social Responsibility), which need periodic attention. Our contribution is mostly methodological and extends the research on text mining and on online big data analytics applied in complex business contexts.

description: The positive effects through a limitation of the MPP-Voltage range of PV-inverters are an increase of
the power, the efficiency and a reduction of inverter system costs. The same power stack could be
used with power limitation or voltage limitation in the PV-system. The losses were analyzed with the
