description: Phosphorus Diffusion Gettering (PDG) is one of the key steps in the fabrication process of waferbased
silicon (Si) solar cells. In the present work, we have assembled a relatively simple model that will enable
us to simulate the evolution of the Fe content and distribution during the whole solar cell fabrication process. The
different pieces of the model have been taken from different authors in order to simulate the formation of the Pkink-
and-tail profile, the simultaneous external Fe gettering towards the P-doped layer and the internal gettering
of dissolved Fe atoms to metal precipitates during different time-temperature profiles. As a first step, we have
successfully simulated some of the experimental results that can be found in literature in order to validate parts of
the presented model. Furthermore, the simulation results show that the initial distribution of metals has a strong
influence on the efficiency of PDG.

description: Pyramidal texture on monocrystalline silicon wafers is a very common surface structure of industrial
monocrystalline silicon solar cells because of its advantage to reduce light reflection. However, pyramidal texture
with big pyramids (15 μm) or small pyramids (0.3 μm) produce lower performance of solar cells. By using a wet
chemical method we produced a pyramidal texture on (100) p-type Czochralski monocrystalline silicon wafers. We
achieved pyramidal texture with pyramid size between 1 μm and 6 μm. After that, we processed industrial silicon
solar cells by using the screen printing method. Solar cells achieved efficiencies between 16.7 % and 17.7 %.

description: We report on growth parameter optimization for fabrication GaInNAs materials with nitrogen
concentrations ranging from 1 to 6%. These compounds, refered as dilute nitrides, are a promising choice for
developing 1-eV sub-cells required in III-V high-efficiency multi-junction solar cells. Specifically, we have
compared the effects of growth temperature and thermal annealing onto optical and structural properties of GaInNAs
p-i-n diodes lattice matched to GaAs. When used in a 3-junction GaInP/GaAs/GaInNAs solar cell, the dilute nitride
structure could generate a short-circuit current density of ~12 mA/cm2 measured in outdoor conditions.

description: In this paper, four configurations of PV array are analyzed and tested for comparison, where four configurations are series-parallel, series-parallel-bypass diode, total-cross-tied and total-cross-tied-bypass diode configuration. Each photovoltaic module is constructed by two 5 inch poly-crystalline cells in series and an array is consisted of connecting 24 modules for output power comparison among four configurations. In other words, it is called the modified Pv array and module. Sun simulator, PASAN b, is used to test the array under various partial shading conditions at standard test condition (STC; 25°C, 1000 [W/m2]). Test results show the performance of totalcross- tied configuration is better than the others. In addition, a total-cross-tied-bypass diode configuration is proposed because the total-cross-tied configuration can’t eliminate generated hot spots under shading conditions.

description: A conversion efficiency of 6.7% for solid phase crystallised poly-Si thin film mini-modules has been
reached by combing a PECVD deposited emitter on planar glass with an absorber layer deposited by high-rate
electron-beam evaporation. The current-voltage characteristics of mini-modules prepared by e-beam evaporation
were systematically studied and optimized by varying the absorber doping concentration and absorber thickness.
Mini-modules deposited with a deposition rate of 600 nm/min exhibited a short circuit density of over 20 mA/cm2
and a fill factor of 70% at a base doping level of 7x1015 cm-3. These characteristics were found to be equivalent to
results achieved on conventional PECVD poly-Si mini-modules of the same structure and on planar substrates but at
much lower deposition rates. The short circuit current density could be raised to 20.8 mA/cm2 by increasing the base
layer thickness to 2.2 μm. These excellent results set new efficiency and current records for e-beam evaporated poly-
Si solar cells and underscore the enormous potential for efficiency improvement upon implementing light trapping.
title: Experiencing Distinctiveness at the Margins of the School: Relatedness, Performance and Becoming a Greek Gypsy
Creators: name: Daskalaki, Ivi
Publisher: name: Goldsmiths, University of London
Year: 2005

description: This thesis focuses on a sedentary Greek Gypsy population in Athens. The arguments presented in this ethnographic study are structured through a discussion of what I call 'the schooling paradox'. This paradox indicates that the children's and adults' acknowledgement of the importance of the school co-exists with the recognition of the incompatibility between Greek Gypsy life and formal education. The degree to which adults entrust in their children the decision whether or not to attend classes, draws attention to the blurred boundaries between Greek Gypsy childhood and adulthood and processes of becoming through which children actively participate in the adults' worlds. Based on the premise that children are subjects with agency, their views reflect broader perceptions of the Greek state and other institutions. Considering these perceptions, the thesis examines Greek Gypsy projects of identification and explores children's and adults' degrees of participation within wider Greek society. Whilst acknowledging the importance of a specific 'Gypsy' sense of distinctiveness, this study recognises that there is a Greek component to it. Here, the experience of being a Greek Gypsy is seen as premised on age and gender-specific embodied performances. These performances are principally located within marriage, work and the kinship network and are sustained through the acquisition of knowledge through practice. This thesis argues that the schooling paradox is symptomatic of alternative processes of learning as well as relationships and practices which inform Greek Gypsies' experiences of becoming and belonging. The schooling paradox provides the vehicle for examining the ways through which an individual and a shared sense of Greek Gypsy distinctiveness are primarily sustained and reproduced at the margins of the school.

description: Conventional light trapping techniques are inefficient at the sub-wavelength scale. This is one of the main
limitation for the thickness reduction of thin-film solar cells. We propose a novel architecture for broadband light absorption
in a 100 nm-thick CIGS active layer. We show that this ultra-thin CIGS solar cell could preserve a constant short-circuit
current while decreasing the active layer thickness by at least one order of magnitude. We focus on numerical optimisation to
achieve a good short-circuit current with tunable multiple resonances. Fabrication issues are discussed.

description: In this paper, we study the performance degradation of thin film photovoltaic module under 4 year’s operation. To analyze the change of maximum power generation when installed outdoor, we select two kinds of thin film (36.5Wp, 58.0Wp) PV modules which are generating electricity in 3kw PV systems then check I-V curve and calculate the degree of performance degradation. Through this experiment, we can find that silicon thin film PV module’s maximum power is reduced to 70% of original one. The detailed explanation is on the following paper
A self-consistent analytical magnetar model: The luminosity of $γ$-ray burst supernovae is powered by radioactivity

description: We present an analytical model that considers energy arising from a magnetar central engine. The results of fitting this model to the optical and X-ray light curves (LCs) of five long-duration $γ$-ray bursts (LGRBs) and two ultra-long GRBs (ULGRBs), including their associated supernovae (SNe), show that emission from a magnetar central engine cannot be solely responsible for powering an LGRB-SN. While the early AG-dominated phase can be well described with our model, the predicted SN luminosity is underluminous by a factor of $3-17$. We use this as compelling evidence that additional sources of heating must be present to power an LGRB-SN, which we argue must be radioactive heating. Our self-consistent modelling approach was able to successfully describe all phases of ULGRB 111209A / SN 2011kl, from the early afterglow to the later SN, where we determined for the magnetar central engine a magnetic field strength of $1.1-1.3\times10^{15}$ G, an initial spin period of $11.5-13.0$ ms, a spin-down time of $4.8-6.5$ d, and an initial energy of $1.2-1.6\times10^{50}$ erg. These values are entirely consistent with those determined by other authors. The luminosity of a magnetar-powered SN is directly related to how long the central engine is active, where central engines with longer durations give rise to brighter SNe. The spin-down timescales of superluminous supernovae (SLSNe) are of order months to years, which provides a natural explanation as to why SN 2011kl was less luminous than SLSNe that are also powered by emission from magnetar central engines.

description: We report for the first time on the growth of various Cu-deficient Cu2ZnSnS4 (CZTS) thin films on
metallic substrates by electro-deposition using ionic liquids. The use of ionic liquid was deliberate to produce Cu-Zn-
Sn precursor thin film without the evolution of hydrogen, resulted in a superior control over its morphological
uniformity even without the use of surfactants. The impurity (e.g. Fe) in-diffusion barrier layers (with ZnO) between
metal substrate and back metal contact were developed by solution Spray pyrolysis method. The Hall Effect
measurements on the ZnO barrier layer has shown a low electrical conductivity which was much desired. A
secondary ion mass spectroscopy (SIMS) & lock-in thermography (LIT) studies which are underway would better
reveal the qualification of the barrier layers. The results have opened up possibility of developing a low cost metallic
substrate based CZTS solar cells and modules with efficiency comparable to a CZTS solar cell using glass substrates.

description: Optically trapped nanospheres in high-vaccum experience little friction and hence are promising for ultra-sensitive force detection. Here we demonstrate measurement times exceeding $10^5$ seconds and zeptonewton force sensitivity with laser-cooled silica nanospheres trapped in an optical lattice. The sensitivity achieved exceeds that of conventional room-temperature solid-state force sensors, and enables a variety of applications including electric field sensing, inertial sensing, and gravimetry. The optical potential allows the particle to be confined in a number of possible trapping sites, with precise localization at the anti-nodes of the optical standing wave. By studying the motion of a particle which has been moved to an adjacent trapping site, the known spacing of the lattice anti-nodes can be used to calibrate the displacement spectrum of the particle. Finally, we study the dependence of the trap stability and lifetime on the laser intensity and gas pressure, and examine the heating rate of the particle in high vacuum in the absence of optical feedback cooling.

description: We have been studying concentrator multi-junction solar cells under Japanese Innovative Photovoltaic
R&D program since FY2008. InGaAsN is one of appropriate materials for 4- or 5-junction solar cell configuration
because this material can be lattice-matched to GaAs and Ge substrates. However, present InGaAsN single-junction
solar cells have been inefficient because of low minority-carrier lifetime due to N-related recombination centers and
low carrier mobility due to alloy scattering and non-homogeneity of N. This paper presents our major results in the
understanding of majority and minority carrier traps in GaAsN grown by chemical beam epitaxy and their
relationships with the poor electrical properties of the materials.

Para esta revisión sistemática se siguieron los principios de la declaración PRISMA 2020. Así, se indagaron estudios enfocados en tratamiento con CoQ10 que hicieran énfasis en rehabilitación de sujetos con síndrome post COVID-19, empleando métodos de búsqueda en las siguientes bases de datos: Europe PCM, SpringerLink, SciELO y PubMed. Los estudios fueron ensayos clínicos, aleatorizados, revisiones sistemáticas. Se procesaron 325 estudios y 08 cumplieron con los criterios de inclusión y exclusión. Los resultados reportan mejoras significativas sobre la fatiga y debilidad (5 estudios). Se puede concluir, por tanto, que la suplementación de Coenzima Q10 tiene efectos positivos sobre la debilidad y fatiga en sujetos con síndrome post COVID-19, por el contrario, 3 estudios de esta revisión no reportaron mejoras en la función mitocondrial. Así pues, nuevos estudios deberían abordar y comprobar, bajo diseños experimentales, los efectos de CoQ10 en la disfunción mitocondrial de pacientes Long COVID-19.

description: Let $X$ be a smooth cubic hypersurface of dimension $n \ge 1$ over the rationals. It is well-known that new rational points may be obtained from old ones by secant and tangent constructions. In view of the Mordell--Weil theorem for $n=1$, Manin (1968) asked if there exists a finite set $S$ from which all other rational points can be thus obtained. We give an affirmative answer for $n \ge 48$, showing in fact that we can take the generating set $S$ to consist of just one point. Our proof makes use of a weak approximation theorem due to Skinner, a theorem of Browning, Dietmann and Heath-Brown on the existence of rational points on the intersection of a quadric and cubic in large dimension, and some elementary ideas from differential geometry, algebraic geometry and numerical analysis.

film composition by the molar ratio of the solution easily. The optical bandgap of the film increased from 1.4 to 3.4eV
with increasing Zn composition ratio. X-ray diffraction patterns showed the 112 or 111 peaks of the chalcopyrite or
sphalerite structure to shift to an altitude angle with increasing the Zn/(Zn+Cu+In) ratio. The ZCIS solar cells with a
structure of glass / ITO / TiO2 / In2S3 / ZCIS / Au were fabricated and showed an efficiency of 4.4% with an open circuit
voltage (Voc) of 0.68V.

solar cell concepts, structuring techniques with up-scaling potential play a key role in their realization.
Interference lithography and Nanoimprint processes are presented as technologies for origination and replication of
fine-tailored photonic structures on large areas. With the interference pattern of two or more coherent waves, a wide
variety of structures can be generated on areas of up to 1.2 x 1.2 m². In combination with subsequent nanoimprint
steps, the industrially feasible production of elaborate structures is possible. After the description of the basic
technologies, four application examples are presented: (1) honeycomb structures for the front side texturization, (2)
diffractive back side gratings for absorption enhancement in the spectral region near the band gap of silicon, (3)
periodic and aperiodic imprinted structures as substrates for TCO deposition, and (4) plasmonic metal nanoparticle

description: We present a dynamical study of the effect of the bar and spiral arms on the simulated orbits of open clusters in the Galaxy. Specifically, this work is devoted to the puzzling presence of high-altitude open clusters in the Galaxy. For this purpose we employ a very detailed observationally motivated potential model for the Milky Way and a careful set of initial conditions representing the newly born open clusters in the thin disk. We find that the spiral arms are able to raise an important percentage of open clusters (about one-sixth of the total employed in our simulations, depending on the structural parameters of the arms) above the Galactic plane to heights beyond 200 pc, producing a bulge-shaped structure toward the center of the Galaxy. Contrary to what was expected, the spiral arms produce a much greater vertical effect on the clusters than the bar, both in quantity and height; this is due to the sharper concentration of the mass on the spiral arms, when compared to the bar. When a bar and spiral arms are included, spiral arms are still capable of raising an important percentage of the simulated open clusters through chaotic diffusion (as tested from classification analysis of the resultant high-z orbits), but the bar seems to restrain them, diminishing the elevation above the plane by a factor of about two.

Impact of strategic use of antiretroviral therapy intervention to the HIV continuum of care in 13 cities in Indonesia: an interrupted time series analysis
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia

description: In 2013 the Indonesian government introduced the strategic use of antiretroviral therapy (SUFA) initiative of expanding access to HIV test and treatment, to help achieve the UNAIDS 90–90–90 targets. However, there has been no comprehensive evaluation of the impact of this intervention in Indonesia. We conducted an interrupted time series (ITS) analysis across 6-years to assess its immediate and medium-term impact. Methods: Monthly aggregated HIV data from all HIV care clinics for persons aged ≥ 15 years were collected from 13 pilot cities. The data period encompassed 3-years prior to SUFA (26 Dec 2010–25 Dec 2013) and 3-years post-SUFA (26 Dec 2013–25 Dec 2016). The ITS was performed using a multilevel negative binomial regression model to assess the immediate and trend changes in each stage of the HIV continuum of care. Results: In the pre-SUFA period, the overall coverage in the respective risk populations for HIV tests, cases, enrolments, eligible cases and ARV initiation were 1.0%, 8.6%, 98.9%, 76.9% and 75.8% respectively. In the post-SUFA period coverage was 3%, 3.8%, 98.6%, 90.3% and 81.2% respectively—with a significant increase in the median number of HIV tests, HIV cases, those eligible for ARV treatment and treatment initiation (p < 0.05 for each). The ITS analysis demonstrated immediate increases in HIV tests (IRR = 1.41, 95% CI 1.25, 1.59; p < 0.001) and an immediate decrease in detected HIV cases per person tested (IRR = 0.77, 95% CI 0.69–0.86; p < 0.001) in the month following commencement of SUFA. There was also a 3% decline in the monthly trend for HIV tests performed (IRR = 0.97; 95% CI 0.97–0.98, p < 0.001), a 1% increase for detected cases (IRR = 1.01, 95% CI 1.0–1.02, p < 0.001), and a 1% decline for treatment initiation (IRR = 0.99,95% CI 0.99–1.0 p < 0.05). Conclusions: SUFA was associated with an immediate and sustained increase in the absolute number of HIV tests performed, detected HIV cases, and close to complete coverage of detected cases that were enrolled to care and defined as eligible for treatment. However, treatment initiation remained sub-optimal. The findings of this study provide valuable information on the real-world effect of accelerating ARV utilizing Treatment as Prevention for the full HIV continuum of care in limited resource countries.

description: Silicon thin film with nanohole array decorated surface is systematically studied via
simulation for solar energy harvesting. It is found that nanohole array structures can significantly
improve the light absorption of the silicon thin film with optimized structural dimensions. Moreover, for
the same thickness and optimized structure dimensions, the nanohole array shows better light trapping
than nanopillar array. The electrical performance of the nanohole array textured silicon thin film solar
cell is also optimized in terms of minority carrier diffusion length, emitter/base doping level, emitter
junction depth and surface recombination velocity. The results provide a practical guideline to design
and fabricate high efficiency and cost effective nanohole textured Si thin film solar cells.

description: We propose and demonstrate a computational imaging technique that uses structured illumination based on a two-dimensional discrete cosine transform to perform imaging with a single-pixel detector. A scene is illuminated by a projector with two sets of orthogonal patterns, then by applying an inverse cosine transform to the spectra obtained from the single-pixel detector a full-color image is retrieved. This technique can retrieve an image from sub-Nyquist measurements, and the background noise is easily canceled to give excellent image quality. Moreover, the experimental setup is very simple.

description: Galactic nuclei typically host either a Nuclear Star Cluster (NSC, prevalent in galaxies with masses $\lesssim 10^{10}M_\odot$) or a Massive Black Hole (MBH, common in galaxies with masses $\gtrsim 10^{12}M_\odot$). In the intermediate mass range, some nuclei host both a NSC and a MBH. In this paper, we explore scaling relations between NSC mass (${\cal M}_{\rm NSC}$) and host galaxy total stellar mass (${\cal M}_{\star,\rm gal}$) using a large sample of NSCs in late- and early-type galaxies, including a number of NSCs harboring a MBH. Such scaling relations reflect the underlying physical mechanisms driving the formation and (co)evolution of these central massive objects. We find $\sim\!1.5σ$ significant differences between NSCs in late- and early-type galaxies in the slopes and offsets of the relations $r_{\rm eff,NSC}$--${\cal M}_{\rm NSC}$, $r_{\rm eff, NSC}$--${\cal M}_{\star,\rm gal}$ and ${\cal M}_{\rm NSC}$--${\cal M}_{\star,\rm gal}$, in the sense that $i)$ NSCs in late-types are more compact at fixed ${\cal M}_{\rm NSC}$ and ${\cal M}_{\star,\rm gal}$; and $ii)$ the ${\cal M}_{\rm NSC}$--${\cal M}_{\star,\rm gal}$ relation is shallower for NSCs in late-types than in early-types, similar to the ${\cal M}_{\rm BH}$--${\cal M}_{\star,\rm bulge}$ relation. We discuss these results in the context of the (possibly ongoing) evolution of NSCs, depending on host galaxy type. For NSCs with a MBH, we illustrate the possible influence of a MBH on its host NSC, by considering the ratio between the radius of the MBH sphere of influence and $r_{\rm eff, NSC}$. NSCs harbouring a sufficiently massive black hole are likely to exhibit surface brightness profile deviating from a typical King profile.

description: For automated PV inverter measurements (including MPP-tracking behaviour) PC controlled PV array simulators with high stability are needed. Between 2000 and 2005 two highly stable and fast PC controlled linear PV array simulators of 25 kW and 20 kW with very good operational results were developed, which have the possibility to operate on I-V-curves with largely different fill factors independent of external weather. With this equipment, many inverter tests have been performed at devices between 100 W and 25 kW [3], [4], [5]. So far with the available test equipment it was not possible to perform inverter tests at power levels higher than 20 to 25 kW. As 100 kW is an important power limit in many countries, in a research project funded by the Swiss Federal Office of
Energy, the PV laboratory was mandated to develop a corresponding PV array simulator of 100 kW (VOC ≤ 810 V / ISC ≤ 156 A). In this paper, the actual state of development and results of the first tests at full rated power are described.
The whole measuring system should be ready for tests with 100 kW-inverters by the end of 2008.

description: In this study we investigate and compare the influence of two different surface passivation methods on
the bulk properties. As passivation layers the widely used PECVD-SiNx:H and the recently developed Al2O3
passivation layer, deposited by atomic layer deposition (ALD), are investigated. Changes in the carrier lifetime due
to the applied temperature (and additionally hydrogen-passivation in the case of SiN) were assessed and special
interest was paid to the interstitial iron (Fei) concentration. We could show that H-passivation, coming from the
hydrogen rich SiN layer, rises lifetimes, but does not alter the Fei concentration. Nevertheless, a reduction of Fei was
observed which is only caused by a temperature-driven precipitation and is not influenced by the H-passivation.

description: In silicon heterojunction solar cells, the passivation of the crystalline silicon wafer surfaces and
fabrication of emitter and back surface field are all performed by intrinsic and doped amorphous silicon thin layers,
usually deposited by plasma-enhanced chemical vapor deposition (PECVD). Since the properties of materials
deposited by PEVCD are directly linked to the plasma properties, plasma diagnostics are very useful tools to
optimize such devices. A novel diagnostic has been developed to measure in-situ the molecular silane depletion
fraction in the plasma during deposition. It is found that the silane depletion strongly depends on the process
parameters, and appears to be a relevant parameter for the quality of the passivating layers. Good passivation is
indeed obtained from highly depleted silane plasmas. Based on this, layers deposited in a large-area PECVD reactor
working at very high frequency (40.68 MHz) were optimized for heterojunction solar cells. All other fabrication
steps were also fully industry compatible, using sputtering for transparent conductive oxide layers and screenprinting
for the front grid. The best 2 x 2 cm2 cell shows a high open-circuit voltage of 717 mV, yielding a
conversion efficiency of 20.3% (aperture area).

description: In this work the influence of the amount of the aluminum paste deposited by screen-printed method in
the bending of a Cz.Si wafer (200 μm), in the Voc, Fill Factor and efficiency. The efficiency of the cells increase with
the amount of Al paste deposited due to an increase in the open circuit voltages because there is less recombination in
the rear surface; however, this positive influence is offset by the increase in the bending of the wafer. A compromise
between these influences is necessary.

description: Rotational modulations of brown dwarfs have recently provided powerful constraints on the properties of ultra-cool atmospheres, including longitudinal and vertical cloud structures and cloud evolution. Furthermore, periodic light curves directly probe the rotational periods of ultra-cool objects. We present here, for the first time, time-resolved high-precision photometric measurements of a planetary-mass companion, 2M1207b. We observed the binary system with HST/WFC3 in two bands and with two spacecraft roll angles. Using point spread function-based photometry, we reach a nearly photon-noise limited accuracy for both the primary and the secondary. While the primary is consistent with a flat light curve, the secondary shows modulations that are clearly detected in the combined light curve as well as in different subsets of the data. The amplitudes are 1.36% in the F125W and 0.78% in the F160W filters, respectively. By fitting sine waves to the light curves, we find a consistent period of $10.7^{+1.2}_{-0.6}$ hours and similar phases in both bands. The J- and H-band amplitude ratio of 2M1207b is very similar to a field brown dwarf that has identical spectral type but different J-H color. Importantly, our study also measures, for the first time, the rotation period for a directly imaged extra-solar planetary-mass companion.

description: Theoretical analysis and experimental research of Si solar cells (SC) with interdigitated back side
contacts (BSC) photovoltaic parameters and photoconversion efficiency at low light level have been done in presence
of floating p+-n junctions and isotype n+-n junctions on frontal (illuminated) surface. It has been found that in the
case of the floating junction the magnitudes of short-circuit current, open-circuit voltage and efficiency, as well as
the magnitude of internal quantum efficiency of photocurrent can decrease significantly due to recombination in the
space charge region (SCR) rather than surface recombination. In the case of the isotype junction this decrease is
absent. These results allow to conclude that the floating p+-n junction at the front surface of the silicon BSC SC
would be appropriate for use only in the case of illumination intensity ≥ 1000 W/m2.
