description: Screen printing, the reference technique for more than twenty-five years for the metallization of crystalline silicon solar cells, can suffer from the medium quality of the contacts it yields, which limits the optimization of highly-efficient solar cells. To solve that, among other parameters, new silver pastes able to contact lowly-doped emitters are being implemented. In this work, we first present a comparison and understanding of the performances of a reference screen printing front silver paste for the formation of contacts on industrial Al-BSF <100>-oriented p-type monocrystalline silicon solar cells with 70 and 100 ohm/sq phosphorous front emitters, using electrical and imaging characterizations. This paste exhibits good performances, in the range of standard screen printing, on both emitter resistivities. In addition, the optimal 3-busbar H-pattern screen printing mask for these cells would allow to print cells with theoretical efficiencies around 19.2-19.5%. Furthermore, this old-generation paste is as adequate as the new-generation ones to contact resistive emitters up to 100 ohm/sq. The electrical characteristics as well as the contact structures are state-of-the-art for screen printing technology and the atomic compositions of the pastes are very similar. The detailed contact structures show the silver colloids and confirm that this current transportation mechanism is dominant for <100>-oriented p-type substrates.

the subject of this work. Thin amorphous SiC films in this study were prepared by PECVD technology. The influence
of post-deposition heat treatment on the properties of prepared Al/a-SiC/c-Si(n)/Al heterojunction structure was
studied by complex impedance spectroscopy in the dark. AC equivalent circuit was obtained by fitting impedance

description: We present new ALMA observations of CO $J$=2$-$1 line emission from the DQ Tau circumbinary disk. These data are used to tomographically reconstruct the Keplerian disk velocity field in a forward-modeling inference framework, and thereby provide a dynamical constraint on the mass of the DQ Tau binary of $M_\ast = 1.27_{-0.27}^{+0.46} \,M_\odot$. Those results are compared with an updated and improved orbital solution for this double-lined system based on long-term monitoring of its stellar radial velocities. Both of these independent dynamical constraints on the binary mass are in excellent agreement: taken together, they demonstrate that the DQ Tau system mass is $1.21\pm0.26\,M_\odot$ and that the disk and binary orbital planes are aligned within $3^\circ$ (at 3$σ$ confidence). The predictions of various theoretical models for pre-main sequence stellar evolution are also consistent with these masses, although more detailed comparisons are difficult due to lingering uncertainties in the photospheric properties of the individual components. DQ Tau is the third nearly equal-mass double-lined spectroscopic binary with a circumbinary disk that has been dynamically "weighed" with these two independent techniques: all show consistent results, validating the overall accuracy of the disk-based approach and demonstrating that it can be robustly applied to large samples of young, single stars as ALMA ramps up to operations at full capacity.

description: TIn this paper we present a newly developed design of rear-colored bifacial p-type PERC solar cells used in double glass modules for building-integrated photovoltaics (BIPV.) The module’s rear side with a diversity of colors provides indoor decoration while the module’s front side with the conventional dark blue color provides power generation without current loss compared to conventional PV modules. Bifacial p-type PERC cells were employed for the module fabrication. The diversity of colors of the cell’s rear side is achieved by means of tuning the thickness of cell’s rear side passivation layer. The reflectivity of the cell’s rear side is measured with a spectrophotometer, and by fitting the measured to the simulated result the passivation layer thickness is determined. We successfully obtained blue, yellow, red and green rear-colored cells which were consequently incorporated into fabrication of rear-colored double glass modules. Both IV and EL characterization were then carried out on these modules. The results show that yellow, red and green cells have similar electrical properties, which we were able to install in one module without too much Isc mismatch. However blue cells have a lower Voc and efficiency value, possibly due to poor rear side passivation quality.

description: We identify [Rb IV] 1.5973 and [Cd IV] 1.7204 micron emission lines in high-resolution (R=40,000) near-infrared spectra of the planetary nebulae (PNe) NGC 7027 and IC 5117, obtained with the IGRINS spectrometer on the 2.7-m telescope at McDonald Observatory. We also identify [Ge VI] 2.1930 $μ$m in NGC 7027. Alternate identifications for these features are ruled out based on the absence of other multiplet members and/or transitions with the same upper levels. Ge, Rb, and Cd can be enriched in PNe by s-process nucleosynthesis during the asymptotic giant branch (AGB) stage of evolution. To determine ionic abundances, we calculate [Rb IV] collision strengths and use approximations for those of [Cd IV] and [Ge VI]. Our identification of [Rb IV] 1.5973 $μ$m is supported by the agreement between Rb3+/H+ abundances found from this line and the 5759.55 A feature in NGC 7027. Elemental Rb, Cd, and Ge abundances are derived with ionization corrections based on similarities in ionization potential ranges between the detected ions and O and Ne ionization states. Our analysis indicates abundances 2-4 times solar for Rb and Cd in both nebulae. Ge is subsolar in NGC 7027, but its abundance is uncertain due to the large and uncertain ionization correction. The general consistency of the measured relative s-process enrichments with predictions from models appropriate for these PNe (2.0-2.5 M_sun, [Fe/H]= -0.37) demonstrates the potential of using PN compositions to test s-process nucleosynthesis models.

description: The Ohmic contact formation between silver thick electrodes and a silicon wafer
is the key for high efficiency solar cells. Many researches had been done to reveal the
contact mechanism and developing silver paste for a low contact resistance using the
“fire-through” technique [1-4]. However, metallization induced recombination have
been dominate because of highly sophisticate front side (i.e. diffusion profile and/or high
quality surface passivation) [5, 6]. We have developed the novel silver paste, and it
showed quite low recombination compared with the conventional paste [7]. The
electrical characteristics have been evaluated by I-V measurement to reveal the contact
mechanism of the silver thick electrode. To clarify the conduction mechanism, metalsemiconductor
Schottky diode TEG was prepared using low resistivity miller n-Si wafer
with PECVD SiNx. Three kinds of paste were used for evaluation. The I-V curve
measured revealed that commercially available state-of-the-art silver paste showed
Ohmic behavior but our novel paste showed Schottky like curve. But both of silver
paste can be work for front side silver paste and our novel one showed low recombination
effect. This Schottky-like contact prevent the recombination under the electrode.

description: There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity. In addition, the component black holes' masses exceeded the limit predicted by stellar evolution. The large masses can be explained by successive mergers, which may be efficient in gas disks surrounding active galactic nuclei (AGN), but it is difficult to maintain an eccentric orbit all the way to the merger, as basic physics would argue for circularization. Here we show that AGN-disk environments can lead to an excess of eccentric mergers, if the interactions between single and binary black holes are frequent, and occur with mutual inclinations of less than a few degrees. We further illustrate that this eccentric population has a different distribution of the inclination between the spin vectors of the black holes and their orbital angular momentum at merger, referred to as the spin-orbit tilt, compared to the remaining circular mergers.

description: We present velocity-resolved maps taken with the Wisconsin H-Alpha Mapper (WHAM) in Hα, [S II] λ6716, and [N II] λ6583 around the well-known O8 III star λ Ori A (HD 36861) (l = 185° to 205°, b = -24° to -1°). The integrated intensity (v(LSR) = -80 to +80 km/s), I(Hα), within WHAM's one-degree beams varies from ~ 190 R near the center to ~ 10 R on the periphery of the nebula where it becomes comparable to foreground and/or background emission in this complex region. Intensity ratios for [N II]/Hα and [S II]/Hα average 0.28 and 0.35, respectively. In both ratios, higher values are found preferentially at larger radii from λ Ori, although the behavior of [N II]/Hα is complicated near the edges of the nebula. The [S II]/[N II] intensity ratio ranges from ~ 0.5 to ~ 1.0, with the value increasing toward larger radii (and lower Hα intensities). Variations of [S II]/Hα, [N II]/Hα, and [S II]/[N II] line ratios in this diffuse region show some similar trends to those seen in the warm ionized medium (WIM) but with generally lower metal-line ratios. As with the WIM, the trends are driven by changes in the underlying physical parameters, most notably the ionization states and gas temperature. We use these extremely high signal-to-noise observations to construct a map of temperature and non-thermal velocity throughout the nebula. Using the line widths of Hα and [S II], we separate thermal and non-thermal components and find spatial trends of these parameters within the nebula.

description: While geometrically frustrated quantum magnets are known for a variety of exotic spin states that are of great interests of understanding emergent phenomena as well as enabling revolutionary quantum technologies, most of them are necessarily good insulators which are difficult to be integrated with modern electrical circuit that relies on moving charge carriers. The grand challenge of converting fluctuations and excitations of frustrated moments into electronic responses is finding ways to introduce charge carriers that interact with the localized spins without destroying the spin states. Here, we show that, by designing a Bi2Ir2O7/Dy2Ti2O7 heterostructure, the breaking of the spin ice rule in insulating Dy2Ti2O7 can lead to a charge response in the Bi2Ir2O7 conducting layer that can be detected as anomalous magnetoresistance. These results demonstrate a novel and feasible interfacial approach for electronically probing exotic spin states in insulating magnets, laying out a blueprint for the metallization of frustrated quantum magnets.

description: The temperature (T) dependent x-ray diffraction (XRD) and resistivity measurements of La0.175Pr0.45Ca0.375MnO3 (LPCMO) have been performed down to 2K to understand the structural and transport properties. From room temperature down to 220K, LPCMO exists in orthorhombic phase with Pnma structure and at 220K, it transforms to charge ordered (CO) monoclinic phase with P21/m structure and remains as it is down to 2K. The CO phase is evident from the occurrence of weak but well defined superlattice peaks in the XRD pattern. This structural transformation is of first order in nature as evident from the phase coexistence across the transition region. These results thus clearly illustrate that LPCMO undergoes a first order structural phase transition from charge disordered orthorhombic phase to CO monoclinic phase at 220K, consistent with temperature dependent resistivity results. Our structural analysis of T dependent XRD data using Rietveld refinement infers that below 220K, LPCMO forms commensurate CO monoclinic P21/m structure with four times structural modulation.

description: This paper reports our mass production of rear p type emitter solar cell on Cz n-Si wafer by means of traditional process. The p emitter is formed by Al diffusion during the firing process of back aluminum electrode. Phosphors diffusion formed n+ layer in front side as Front-Surface-Field (FSF) layer. SiNx film is formed in front by PECVD as passivation layer. Ag fingers in front side and Ag bus bars in rear side are made by screen printing and firing through process. Almost all of the processes are the same as that of the commercial p-Si wafer solar cell. But Al paste is adjusted according to the requirement of Al doped rear emitter. 100MW production lines of this kind of solar cell were established. The average efficiency is 17.4% for mass production. The highest efficiency arrived to 18.76%. The character measurements were carried out. The light-induced degradation (LID) and Potential-Induced degradation (PID) cannot be found. Consider these advantages, even though the efficiency of this kind of solar cell is not as good as p type mono Si solar cell ( around 19%), it is still quite competitive.

Internationalization Experiences of Ethiopian Higher Education in the Pandemic Era.

Year: 2023

description: Higher Education Institutions (HEIs) are undergoing institutional reforms including curriculum revisions, university-industry linkages, twinning programs, joint research, etc. in an attempt to cope with fast-changing global and local situations. The three missions of HEIs incorporate teaching learning, research, and community service. Some HEIs are in the ivory tower detached from real-life situations and far from addressing existing and emerging problems of society. This shows that the third wing of HEIs, i.e., community service has been given less attention. In Ethiopia, there are expansions at all educational levels. However, the education system needs to travel a long distance in order to improve the quality. Inequality of education is observed between urban–rural (nomadic areas) and boys – girls. The pandemic also posed limitations on face-to-face learning. Moreover, HEIs focus on knowledge with inadequate consideration for value and skill development. By way of addressing these issues, the paper aims at exploring practices, gaps, and emerging trends in the internationalization of Ethiopian higher education. In order to achieve these objectives, different methods including desk review, theoretical sketch, and reflections from practice coupled with institutional examples were employed. Based on the above desk review, research results, and institutional examples, internationalization of higher education in Ethiopia can be labeled at the infant stage with heavy reliance on Western approaches and considered weak in resources and networks. In order to counter this, HEIs in Ethiopia need to make use of the current virtual and blended learning environment so as to initiate flexible platforms without neglecting indigenous and lifelong practices. Hence, parallel to promoting the internationalization of higher education, the de-internationalization HEIs also has to be exercised so as to scale up homegrown strategies.

By optimizing the module design and materials to reduce series resistance losses and optical losses in the module production processes which are available for mass production. More than 100,000 PERC cells have been mass produced with average efficiency of 20.55% and the maximum module power of up to 300.3Wp. The cell and module products have passed all internal and external qualification procedures of the IEC 60904 and IEC 61215 test criteria.

description: We consider a nonlinearly coupled electromechanical system, and develop a quantitative theory for two-phonon cooling. In the presence of two-phonon cooling, the mechanical Hilbert space is effectively reduced to its ground and first excited states, allowing for quantum operations at the level of individual phonons and preparing nonclassical mechanical states with negative Wigner functions. We propose a scheme for performing arbitrary Bloch sphere rotations, and derive the fidelity in the specific case of a $π$-pulse. We characterise detrimental processes that reduce the coherence in the system, and demonstrate that our scheme can be implemented in state-of-the-art electromechanical devices.

description: The aim of this work is to evaluate a novel approach using an organic material together with silicon substrates to attain hybrid devices with improved electrical performance. In this case, the passivation properties of a hole conducting polymer, PEDOT:PSS, deposited on top of silicon wafers have been characterized. For this purpose, various silicon surface morphologies (textured and polished) and substrates doping (p-type and n-type) have been studied. After the organic material was deposited by means of a spray technique on both sides of the silicon substrates, effective lifetime measurements have been performed by different techniques (QSSPC, PCD and MWPCD) and the measured lifetime and estimated surface recombination velocity have been analyzed for the studied substrates. On polished wafers, effective lifetime values exceeding 1 ms have been obtained, implying a surface recombination velocity of less than 10 cm/s and confirming the valuable passivation effect of PEDOT:PSS material over crystalline silicon wafers. At last, some simulations have been done to analyze the potential performance of a hybrid device using silicon substrates as the inorganic material and PEDOT:PSS as the organic component.

description: This paper is an exposition of the relationship between Witten's Chern-Simons functional integral and the theory of Vassiliev Invariants of knots and links in three dimensional space. We conceptualize the functional integral in terms of equivalence classes of functionals of gauge fields and we do not use measure theory. This approach makes it possible to discuss the mathematics intrinsic to the functional integral rigorously and without functional integration. Applications to loop quantum gravity are discussed. We thank the organizers of the Conference on 60 Years of Yang-Mills Gauge Field Theories (25 to 28 May 2015) for the invitation and opportunity to speak about these ideas in Singapore.

title: Exploration of the leadership process through structures and outcomes
Creators: name: Ozadowicz, Carolina
Publisher: name: University of Reading
Year: 2025

description: This quantitative study delves into the dynamic nature of leadership, examining its structure and outcomes through the lens of shared leadership literature (Conger, 2003; Carson et al., 2007) and the Direction, Alignment, and Commitment (DAC) framework (Drath et al., 2008). Through a blend of cross-sectional and sequential modelling, this research employs a two-wave analysis on a matched sample of 29 student teams working on a task. Shared leadership is quantified using Social Network Analyses, particularly Importance Weighted Density (IWD) (Lemoine et al., 2020; Xu et al., 2022). The analysis revealed a positive correlation between shared leadership and leadership outcomes and shared leadership and team task performance through commitment. However, the direction-performance relationship was insignificant, while alignment only impacted performance at the task’s conclusion. This study contributes to leadership theory by introducing the General Theory of Leadership (GOL). This evolving, interdisciplinary framework integrates diverse leadership theories and perspectives, using adaptable “maps” to visualise various aspects of leadership. It aims to foster a comprehensive understanding of leadership, allowing for continuous adaptability and promoting cross-disciplinary collaboration. The study further proposes the “Pronouns Framework” for categorising leadership literature and the “Multidimensional Continuum of Leadership Outcomes” to underscore leadership outcomes’ complex, dynamic and ever-evolving nature.

description: Electrically conductive adhesives (ECAs) based on copper particles dispersed in a high performance elastomeric matrix were developed for PV applications. The base metal particles were coated with a protective conductive layer to provide long term stability and offer an alternative to high cost silver and silver–coated particles in conductive adhesives. The ECAs were tested in one-cell mini-modules of various configurations including multi busbar and back contact MWT modules, and compared to solder and silver containing adhesives. The modules passed 2000 hours of damp heat testing and 400 thermal cycles under operating current without appreciable power degradation suggesting that these ECAs are suitable for applications in photovoltaics.

description: COVID-19 brought worldwide crises to all levels of education and Ethiopia is not an exception. This research was conducted on the teaching-learning process of HEUC to learn from the experiences of a sudden shutdown of regular classes and a shift into e-learning platforms during the pandemic. The assessment was conducted looking into the perspectives of students involving survey interviews, comparison of grade-based assessments between online and face-to-face classes, observations, and informal interviews with students and instructors. A random sample of 106 students participated in the research in addition to comparing grades of 512 first-year undergraduate students and 181 graduate students in the online and face-to-face classes. Some of the locally validated instruments named “Model for E-Learning Systems Success” was used for the survey adding an open question section to collect the perspectives of students. The results of the study showed that students generally had a negative view of online learning. They reported feeling isolated and disconnected from their teachers and classmates. They also found it difficult to stay motivated and focused on their studies. The findings of this study suggest that the COVID-19 pandemic has had a negative impact on education in Ethiopia. Students and teachers have struggled to adapt to online learning, and this has led to a decline in academic performance. One way to address these challenges is to provide students with more support and resources. This could include offering tutoring, counseling, and other forms of support. In addition, this could include providing more interactive and engaging content, as well as making sure that the platforms are user-friendly. Finally, it is important to provide teachers with training on how to teach effectively online.

description: In this contribution, the state of the art wet chemical saw damage removal and texturing in wet bench
one of crystalline silicon through HF/HNO3 is replaced completely by a maskless Inductively Coupled Plasma (ICP)
process through SF6 and O2. In contrast to a Capacitively Coupled Plasma (CCP), the ICP process does not apply a
self-bias on the silicon sample. Therefore, the ion acceleration and ion induced surface damages are reduced. After
the ICP saw damage removal and texturing, the samples were double sided industrial phosphorous doped, PECVD
SiNx passivated and thermal activated in a belt furnace. The ICP texture forms parabolic like surface structures with a
height and width of ≈ 400 nm. Hemispherical reflection measurements show a significant reduction of the reflection
between 400-700 nm. The average reflection of the ICP samples is 8.95 % between 200-1400 nm. QSSPC
measurements show an effective lifetime of the minority carriers of 72 μs at 1015 cm-3 minority carrier density. This is
a decrease of approximately 30 μs compared to the HF/HNO3 reference wafers, likely caused by the enhanced
effective surface area or plasma induced impurities by the ICP texture. By means of SEM images, it is shown that an
industrial surface passivation of ICP textures through a PECVD SiNx deposition is possible. The SEM images show a
completely covered ICP texture through SiNx.

description: Recent breakthroughs in Artificial Intelligence have shown that the combination of tree-based planning with deep learning can lead to superior performance. We present Adaptive Entropy Tree Search (ANTS) - a novel algorithm combining planning and learning in the maximum entropy paradigm. Through a comprehensive suite of experiments on the Atari benchmark we show that ANTS significantly outperforms PUCT, the planning component of the state-of-the-art AlphaZero system. ANTS builds upon recent work on maximum entropy planning methods - which however, as we show, fail in combination with learning. ANTS resolves this issue to reach state-of-the-art performance. We further find that ANTS exhibits superior robustness to different hyperparameter choices, compared to the previous algorithms. We believe that the high performance and robustness of ANTS can bring tree search planning one step closer to wide practical adoption.

description: The relationship between the quality of silicon wafers and annealing effect with several thermal budgets simulating different cell fabrication processes were investigated in this study. Various types of 156 x 156 mm2 n-type CZ wafers were evaluated in this study. The effective minority carrier lifetimes were measured by a photo-conductance lifetime tester with chemical passivation. As the results, the lifetimes increased or decreased depending on the annealing conditions, i.e. temperature and duration. These differences might be due to the growth conditions of wafers, such as thermal budget during the growth. By analyzing the difference in the growth conditions and annealing conditions, we investigate the relationship between the effective lifetime and annealing processes.
An examination of ‘explicitation techniques’ to enhance decision-making in Korfball: an Action Research study
Creators: name: Hunter, Alice
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Physical education and development curriculum and pedagogy

description: This thesis develops the use of ‘explicitation techniques’as a pedagogical tool for coaches to enhance players’ awareness and decisions.Recent research has highlighted a new appreciation for the use of phenomenological methods in sports coaching(e.g. Mouchet, Morgan & Thomas, 2018). Furthermore, Mouchet’s research (2005; 2008) has highlighted the use of explicitation interviews to enhance rugby players’ understandings of previous decisions. Through extended questioning, the interviewer attempts to invoke an ‘evocative state’ of the interviewee where they re-livea previous experience in order to access information stored in the subconscious. By utilisingan Action Researchapproachover twelve weeks, the aim of the study was to developthe use of these techniques within my own coaching practice in order to enhance my players’ game awareness and develop their in-game decision-making. The study used a group of five experienced Korfball players who engaged with the explicitation informed interviews as part of their regular training sessions, they then discussed their experiences in Focus Groupsat the end of each Action Researchcycle. The results extendthe existing research into ‘explicitation interviews’ by developing theappliedutilityof explicitation techniques through short interviewsduring coaching practice.The results show that through engagement with these interviews the participants developedtheir game awareness whilst playing and believed that further engagement in the explicitation techniques would be beneficial for themselves andother players.

description: The distortion of six different intrinsic metrics and quasi-metrics under conformal and quasiregular mappings is studied in a few simple domains $G\subsetneq\mathbb{R}^n$. The already known inequalities between the hyperbolic metric and these intrinsic metrics for points $x,y$ in the unit ball $\mathbb{B}^n$ are improved by limiting the absolute values of the points $x,y$ and the new results are then used to study the conformal distortion of the intrinsic metrics. For the triangular ratio metric between two points $x,y\in\mathbb{B}^n$, the conformal distortion is bounded in terms of the hyperbolic midpoint and the hyperbolic distance of $x,y$. Furthermore, quasiregular and quasiconformal mappings are studied, and new sharp versions of the Schwarz lemma are introduced.
