description: In our previous work, we presented cell efficiency beyond 21 % achieved by our unique printed-AlOx passivated emitter and rear cells (PERC) technology. In this paper, we demonstrate that the efficiency of this printed-AlOx PERC cells can be further improved by synergizing both improvements in front passivation and rear passivation. These passivation-improvement technologies are selective emitter (SE), SiOx/SiNx dual layer capping (DL CAP) and improved anti-reflection coating (Imp. ARC), respectively. In DL CAP technology we developed a SiOx paste for screen-printing deposition of SiOx layer. Compared to our standard PERC cells, a significant average efficiency gain of 0.45 % was achieved, in which SE, DL CAP and Imp. ARC contributed to the efficiency gain of 0.16 %, 0.13 % and 0.16 %, respectively. We also demonstrate that an average efficiency of 21.44 % with the best efficiency of 21.52 % was achieved with these technologies by carefully choosing the in-coming wafer quality and well controlling each process step. Moreover, it is worthy to note that our developed DL CAP technology, i.e. implementing the printed-SiOx layer in conventional SiNx capping layer, can be easily integrated to existing production line with minimum additional capital cost for equipment and can be applied to other vapor-phase-deposited-AlOx PERC cells as well.
Tectonothermal history and evolving geodynamic setting of the Peake and Denison Block and Northern Gawler Craton, South Australia

description: The Peake and Denison Block located in the far north east of South Australia offers a rare geological window into the basement of the dominantly buried northern Gawler Craton Proterozoic basement. The relative position of the Peake and Denison Block is an important location in the context of plate reconstruction models as it represents an interpreted marginal domain. Detrital geochronology of the Peake Metamorphics indicates three distinct depositional sequences were deposited over a 60 Myr period between 1800 and 1740 Ma. The earliest volcano-sedimentary sequence of the Peake Metamorphics was deposited at ~1800 Ma sequence followed shortly after by a second depositional event at ~1780 Ma and a third at ~1740 Ma. The two earliest sequences preserve detrital zircon populations that indicate they may share a common protolith ancestry with similarly aged sequences in Mt Isa's Western Fold Belt. Following a depositional hiatus a third sequence of volcanics and sediments were deposited at ~1740 Ma which may have sourced material from either locally reworked earlier sequences of the Peak Metamorphics or alternately the more distant Arunta Region of Northern Australia. Sediment deposition is interpreted to have been halted by basin inversion associated with the onset of the Kimban Orogeny at ~1710 Ma which produced at least three deformation events. This period of orogenesis was characterised by an early extensional fabric which was later refolded by two orientations of folding, accompanied by Upper Amphibolite facies metamorphism. Regional geophysical analysis indicates Kimban orogenesis extensively affected the Northern Gawler Craton and was proceeded by at least seven additional periods of faulting, shearing or folding. Preliminary geophysical analysis of the region to the south of the traditional margin of the Mt Isa Block appears to indicate the presence of a deeply buried continuation of the North Australia Craton. Multidisciplinary analysis inclusive of structural, chronological and geophysical observations indicate the Peake and Denison Block may represent the translocated southern margin of the North Australian Craton. It is envisaged the Peake and Denison Block was detached, rotated and finally reattached during the latter part of the Proterozoic.

description: Excerpts from the report: The Ohio River Basin covers parts of 11 states and comprises a significant portion of the Nation’s agricultural production. The Basin is particularly important in production of feed grains and livestock. Moreover, agriculture plays a key role in the general economy of the Basin. This report provides information on the long-term outlook for output and employment in agriculture in the Basin. Such information is intended to be used in the comprehensive plan for development of the Basin's water resources. The projection model used in this study will be useful in developing estimates of the potential for the improved management of water resources, including drainage, flood control and irrigation. The primary objective of this study is to identify the pattern of land use that farmers in the Basin likely will use to satisfy future agricultural production requirements. A second objective is to develop a projection model that will permit analyses of the effect of agricultural water resource management measures. Other objectives include the development of rural farm population and employment estimates for the sub-basins in the study area.
description: A framework analysis of the water and related land resource problems in the Ohio River Basin is being made. The analysis is intended to include the combined interest of flood control, drainage, irrigation, navigation, water supply, water-quality control, recreation and other beneficial uses. In order to provide broad and adequate coverage of these interests, the Ohio River Basin Coordinating Committee, which is composed of representatives of the several State and Federal agencies, including those of the Department of Agriculture, will be coordinating the studies in support of the framework analysis. The Corps of Engineers, Department of the Army, one of the participating agencies studying the Ohio Basin, has a leadership role for the framework analysis and supporting studies. This report is the agricultural economic base study with projections which represent an in-depth study of one of the principal economic sectors in the Basin--agriculture. This analysis was performed by the Economic Research Service, U. S. Department of Agriculture and was supported by funds transferred to the Economic Research Service from the Corps of Engineers, Department of the Army.

description: Transient Electromagnetic (TEM) surveys have improved significantly over the past 30 years and are now being applied to applications as diverse as ground water surveys and identifying unexploded ordinances. Recent improvements have focussed on reducing the shut off time to enable earlier time readings and greater resolution in the near surface. This project explored the possibility of additional improvements by reducing loop sizes further and managing resultant kickback issues through the use of components in the configuration, such as resistors. The aim was to reduce loop sizes while still being able to create quality surface plots and Conductivity vs. Depth Images (CDI). I explored ways of reducing the early time response through analysis conducted using LT Spice, and then tested the results through a series of experiments. I surveyed a Sandringham park with a small mobile TEM instrument with small loops (triangular loops with 3m sides) and conducted a magnetic survey. The park had previously undergone magnetic and TEM surveying, and was known to be contaminated with subsurface objects. I then did a full survey with the same instrument with 2.5x2.5m loops, optimised according to the results from testing undertaken. Finally, the results of the optimised survey were compared to the magnetic survey to validate the results, and previous TEM surveys to determine if the optimisations succeeded in their aim. Comparing the results of the survey using 2.5 x 2.5m loops with those of past site surveys showed that dampening components reduced noise to a manageable level and enabled an accurate surface plot. Analysis of the two TEM surveys taken using the same equipment at Sandringham Park demonstrated the improvements available through managing the electrical current with components. Improvements were also made to the ability to create CDI, however the images created were still incomplete.

description: In this paper, we explore the influence of interstitial iron on studying boron-oxygen related degradation
in p-type Czochralski silicon. We show that the presence of interstitial iron can potentially explain several key
experimental results used to derive theories on the fundamental properties of the boron-oxygen defect. A theoretical
analysis of the influence of interstitial iron and the boron-oxygen defect concentrations on the apparent capture cross
section ratio indicates that at a concentration of 4 × 1011 /cm3, interstitial iron can result in an apparent capture cross
section ratio of >50 for a typical normalised boron-oxygen defect density after fast degradation. With the same
interstitial iron concentration, after full degradation, the apparent capture cross section converged to the lifetime ratio
with only boron-oxygen defects. We then compare the literature data of first annihilation rate of B-O defects after rapid
degradation, to the kinetics of iron-boron pair association. The similar reaction rates suggest that with no iron, after
either fast- or slow- degradation, only a single stage of recovery occurs. Another key potential influence of iron occurs
when modulating the applied voltage used to induce B-O defect formation. Reducing the applied voltage can result in
the association of Fe-B pairs and a subsequent recovery of VOC. We conclude that careful attention must be paid to
interstitial iron when studying boron-oxygen defects and that the current models related to boron-oxygen defects may
need to be revised.
Diagonally cyclic equitable rectangles and cyclotomic orthomorphisms
Creators: name: Fear, David
Publisher: name: Monash University

Subjects: Uncategorized

description: This thesis deals with two related combinatorial topics, namely cyclotomic orthomorphisms and diagonally cyclic equitable rectangles. An orthomorphism θ of a finite field F is a permutation of the elements of F satisfying θ(x) - x is also a permutation of F. The orthomorphism θ is cyclotomic if θ(x)/x is constant on cosets of a subgroup S of the multiplicative group of F. The index of θ is the index of the subgroup S. Two orthomorphisms θ, ϕ are orthogonal if θ - ϕ is a permutation. We present nearly complete solutions to two open problems relating to cyclotomic orthomorphisms posed by A. B. Evans in 1992. In particular, we show that cyclotomic orthomorphisms exist for almost all plausible indices. Also, sets of pairwise orthogonal cyclotomic orthomorphisms of any possible set of indices exist, provided the field is large enough. An equitable rectangle is an r x c rectangle containing v symbols, where each row and column contains the symbols in the most balanced, or equitable, way possible for the given parameters (r, c, v). Motivated by diagonally cyclic Latin squares, we introduce a new type of equitable rectangle called a diagonally cyclic equitable rectangle (DCER). One advantage of studying DCERs is that we are able to easily generate an equitable rectangle that is orthogonal to any DCER. We characterise which parameters (r, c, v) allow the existence of a DCER.

description: Polymorphisms in microsatellites have been linked to phenotypic diversity in several prokaryotic and eukaryotic organisms. Expansions in triplet repeats underlie several neurodegenerative disorders in humans. We are using Arabidopsis as a model to investigate phenotypic variation conferred by repeats and its natural genetic modification. The Arabidopsis Bur-0 strain harbours a triplet expansion in the IILJ gene, which confers a cryptic growth arrest phenotype. In crosses with Col-O this phenotype do not segregate as a monogenic trait suggesting the presence of modifiers. In the initial chapter, using the Bur-0/Col-0 mapping populations, we have uncovered the genetic architecture of this modifier. In the next chapter of the thesis, we have also tried to understand the role of methylation in the modulating the instability of the repeats in Arabidopsis by using a chemical demethylation compound and by analysing the expression of genes that play a pivotal role in establishment and maintenance of the three different types of methylation. Although the IILJ repeat variability is seen in the intron, in the final chapter, we have explored the variation in the exonic repeats by screening for genes that contain the repeats, which also are predicted to be polymorphic. We have identified some interesting genes and have initiated investigations on the phenotypic consequences of repeat variability in these genes. Identifying modifiers for such deleterious phenotypes and identifying other genes that have repeat variability in Arabidopsis that have striking functional resemblance to human disorders are quintessential to be able to undertake an in depth study the features and aspects pertaining to the understudied and unestablished mechanisms leading to triplet repeat disorders and in the future might pave ways to develop potential therapeutical targets and methods.

description: Penta-graphene (PG) has been identified as a novel 2D material with an intrinsic bandgap, which makes it especially promising for electronics applications. In this work, we use first-principles lattice dynamics and iterative solution of the phonon Boltzmann transport equation (BTE) to determine the thermal conductivity of PG and its more stable derivative - hydrogenated penta-graphene (HPG). As a comparison, we also studied the effect of hydrogenation on graphene thermal conductivity. In contrast to hydrogenation of graphene, which leads to a dramatic decrease in thermal conductivity (from 3590 to 1328 W/mK - a 63% reduction), HPG shows a notable increase in thermal conductivity (615 W/mK), which is 76% higher than that of PG (350 W/mK). The high thermal conductivity of HPG makes it more thermally conductive than most other semi-conducting 2D materials, such as the transition metal chalcogenides. Our detailed analyses show that the primary reason for the counter-intuitive hydrogenation-induced thermal conductivity enhancement is the weaker bond anharmonicity in HPG than PG. This leads to weaker phonon scattering after hydrogenation, despite the increase in the phonon scattering phase space. The high thermal conductivity of HPG may inspire intensive research around HPG and other derivatives of PG as potential materials for future nanoelectronic devices. The fundamental physics understood from this study may open up a new strategy to engineer thermal transport properties of other 2D materials by controlling bond anharmonicity via functionalization.
The behaviour in captivity of the dasyurid marsupial Phascogale tapoatafa (Meyer)

description: The aim of this study was to investigate the behaviour in captivity of the dasyurid marsupial Phascogale tapoatafa. Each behaviour was initially described and defined in terms of its observed effect, whether on the animal itself, on a conspecific, on a prey species or on an object or structure. Locomotor, exploratory and grooming behaviour of solitary animals is described. Movements involved in prey catching are defined, and their sequential relationships in encounters with various prey are examined. Movements do not occur randomly, but are ordered on the basis of facilitation of one movement by another, and of feedback to the animal from the situation and the behaviour of the prey. Prey are not divisible into classes on the basis of the predator's responses to them. Data available for other dasyurids is compared. The adaptive value of prey-catching behaviour is discussed in terms of the ability of the prey to resist predation. The reproductive strategy is examined with both field and laboratory studies. P. tapoatafa exhibits a life-history strategy similar to that of Antechinus stuartii, in which all males die after first breeding. The adaptive value of this strategy is discussed in terms of reproductive effort and the predictability of the environment. Nest-building and copulatory behaviour are briefly described. The development of behaviour is described in terms of the acquisition by the young of sensory modalities and locomotor skills, and of the changing relationships amongst the litter-mates and between the mother and her offspring. The daily pattern of activity is described. On short nights, the animal may be active for most of the night. During winter, the night is divided into periods of activity and periods of inactivity. The survival value of this strategy is discussed in terms of feeding and energetics. Communication is described in terms of the sensory modalities used, the signals observed and the observed effect on other animals. P. tapoatafa shows a small range of auditory signals which may form a graded communication system. Olfactory marking by males is pronounced during the breeding season. Olfactory cues may signal physiological state and assist in individual recognition. Agonistic behaviour is briefly described in relation to dispersal of the animals for breeding.
The sensitivity of a modelled tropical cyclone to SST and CAPE

description: In this thesis the sensitivity of a modelled tropical cyclone to sea surface temperature (SST) and Convective Available Potential Energy (CAPE) is investigated. In Chapter 1 previous studies on this topic are discussed and an overview is given of our current knowledge of the effects of latent and sensible heat fluxes from the ocean on tropical cylcones. In Chapter 2 the experiments that make up this study are descibed in some detail. They have been carried out to compare the importance of SST to that of CAPE on tropical cyclone intensity. In order to achieve this, three experiments were designed, a control experiment, an experiment with increased SST and finally an experiment with increased SST, but CAPE equal to that of the control run. The simulations were carried out with the CSIRO Division of Atmospheric Research Limited area model using the Betts Miller cumulus parameterisation scheme. Both the model and this scheme are described in Chapter 3. The tropical cyclone used in this study is Tropical Cyclone Connie, which occurred in the Timor Sea from 15 to 23 January. The track and central pressure of the control simulation are compared with the observations and other simulations of the same storm. The simulation in this study compares very well to the other simulations and given its coarse resolution of 76 x 76 km, produces an acceptable simulation of cyclone Connie, given its coarse resolution of 76 x 76 km. When comparing the three experiments to each other it is found that the storm with increased SST and increased CAPE produces the strongest tropical cyclone. Finally, the sensitivity of the Betts Miller scheme to a model parameter called the relaxation time is discussed briefly. The relaxation time simulates the lag between the large scale forcing and the convective response. It was found that a decrease in relaxation time leads to faster convective adjustment and deeper tropical cyclones. It is concluded in Chapter 5 that SST is not as obviously tied to tropical cyclone intensity as was previously thought. Evaporation from the surface was found to play a very important role, but the importance of CAPE is still unclear. For that reason it will be necessary to perform more simulations with other convective schemes that respond directly to CAPE and are independent of external parameters that have not been verified against observations.
The carbohydrate associated with the collagen fibres of cartilage

description: The present study was undertaken with a view to establishing the qualitative and quantitative distribution of the carbohydrate moiety (or moieties) reported to be associated with the collagen fraction in cartilage. The study was extended to compare the collagenous fractions from both immature (embryonic) and mature cartilage tissue, in order to test the hypothesis invoking a role for one or more of these components in the ultimate organization of the extracellular collagen framework. Results of the present study show that the hexoses of youngbovine nasal cartilage residue (YBNCR) are distributed in the following manner: Over 40% are found in the hydroxylysine linked carbohydrate units consisting of glucosylgalactosylhydroxylysine and galactosylhydroxylysine in a ratio of 2:1. About 7% of the hexoses are associated with a collagen-linked heterosaccharide unit. The rest are accounted for by the keratan sulphate and chondroitin sulphate of proteoglycan. The hydroxylysine linked carbohydrate units are located in highly cross-linked regions of collagen whereas the trypsin susceptible, less ordered part of collagen contains the heterosaccharide moiety. The component sugars of the heterosaccharide are mannose, galactose, glucose and glucosamine with smaller quantities of fucose, galactosamine and sialic acid. The amino acid residue likely to be involved in the peptide-carbohydrate linkage is either aspartic or glutamic acid (or their amides). No such collagen linked heterosaccharide is present in the embryonic bovine nasal cartilage residue (EBNCR). The EBNCR also differs from the YBNCR in that it contains much less proteoglycan and noncollagenous protein. Trypsin causes much more extensive degradation and solubilization of the collagen fibres in EBNCR. Glucosylgalactosylhydroxylysine appears to be the predominant hydroxylysine linked carbohydrate unit in embryonic cartilage.

description: This article takes issue with the notion of embodied knowledge by focusing on habit—the habit of craftsmen, artisans, musicians and scholars. The argument has two components. The first is to show that the habits that enable practitioners to move on in the accomplishment of their tasks are neither tacit nor sedimented in the body but generated and enacted in an attentive and kinaesthetic correspondence with tools, materials and environment. This correspondence is not silent and still but noisy and turbulent, open and alive to the world. To describe it, we adopt the notion of hapticality. In the domain of hapticality, thinking is the churn of a mind that stirs and is stirred by the sounds and feelings of the milieu. This why habitual action is also thoughtful, characterised by an awareness that is not so much cognitive as concentrative. This leads to the second part of the argument, which is to show that words, too, are living things, immersed in the currents of hapticality. Thus we refute the opposition, built into the constitution of the academy, between verbalisation and embodiment. Work and words, we insist, are animate. They both unfold in habit and afford ways of telling.

Molecular taxonomy and phylogenetic analysis of freshwater fish fauna within Malaysia with special emphasis on the Cyprinidae

description: Malaysian freshwater fish are significant economically and ecologically, yet the species making up this highly diverse fauna are going extinct at a greater rate than species can be identified and described using conventional systematic approaches. DNA barcoding based on nucleotide sequence of the mitochondrial gene cytochrome c oxidase subunit 1 (COI), is making a significant contribution to the identification and discovery of fish species worldwide, but has not been applied on any significant scale to Malaysian freshwater fish fauna. The first part of this thesis is devoted to assess the efficacy of DNA barcoding approach in identifying Malaysian freshwater fish species. A total of 181 COI sequences from 29 putative fish species were generated and compared with sequences from reference samples obtained in this study and records on BOLD and GenBank databases. Overall, the results show a moderate level of success of COI-based barcoding as only 132 of 181 COI sequences (73%) were assigned to those expected from field-based identification. However, the current study reveals that the relatively low success rate of COI barcoding is largely due to field based misidentification, presence of cryptic species and/or lack of appropriate reference sequences rather than any failure of the barcoding approach itself. The second part of the study focused on investigation of the phylogenetic relationships within local Cyprinidae family, which is the largest and most widely distributed family of Malaysian freshwater fish. The phylogenetic relationships and subfamily classifications within 16 Malaysian Cyprinidae species were investigated using concatenated sequence of four mitochondrial genes (COI, 16S rRNA, D-loop and Cyt-b). As 13 of 16 Malaysian Cyprinidae species in this study were from the subfamily Barbinae, the resultant phylogenetic trees based on maximum likelihood (ML) and Bayesian analyses show that this subfamily is a polyphyletic group. Further, phylogenetic relationships of the Malaysian Cyprinidae with 23 Cyprinidae species from Vietnam were studied based on concatenated sequence of three mitochondrial genes (16S rRNA, D-loop and Cyt-b). This comparative evaluation confirms the unreliability of the current subfamily concepts within the family, and reveals several taxonomic anomalies between the two fish faunas that will require further investigation using more extensive taxon, gene and geographic sampling.

description: Starting from the primary representation of neutrosophic information, namely the degree of truth, degree of indeterminacy and degree of falsity, we define a nuanced representation in a penta valued fuzzy space, described by the index of truth, index of falsity, index of ignorance, index of contradiction and index of hesitation. Also, it was constructed an associated penta valued logic and then using this logic, it was defined for the proposed penta valued structure the following operators: union, intersection, negation, complement and dual. Then, the penta valued representation is extended to a hexa valued one, adding the sixth component, namely the index of ambiguity.

description: High performance multi-crystalline silicon (HP-mc Si) wafers are usually grown by directional
solidification of molten silicon from an unmelted layer consisting of silicon grains. The HP-mc Si ingots allow
producing solar cells with high efficiency by decreasing the structural defects in silicon, especially dislocation clusters.
Nevertheless, it has the disadvantage of losing important usable ingot length because of a remaining unmelted silicon
layer and a larger bottom red zone than for standard multi-crystalline silicon ingots. Further, longer process times are
needed for the careful melting process. A self-nucleating crucible where nucleation is directly governed by the crucible
bottom without any silicon grain layer has been developed to overcome these issues.
The new developed Vesuvius HP-mc crucible was tested in laboratory G1 as well as in industrial G4 scale and was
compared to standard crucibles. Within the study grain structure properties as well as recombination active defect
content and cell efficiencies on ingots and wafers obtained by the two crucible types were explored.
The results show clearly that ingots originating from the self-nucleating crucible can reach a similar quality than HPmc
ingots grown by a silicon seeding process. It will be shown that using a self-nucleating crucible can lead to a
significant lower dislocation content and higher cell efficiencies and then subsequently can contribute to a significant
wafer cost reduction.

description: To unravel the origin of the dielectric anomaly at the antiferromagnetic ordering of magnetoelectric Bi$_2$Fe$_4$O$_9$ we performed neutron powder diffraction measurements across the N$\acute{\rm e}$el temperature, $T_{\rm N}$. Both local structures and long-range symmetry are studied using the complementary analyses of atomic pair distribution function (PDF) and Rietveld methods at temperatures 300~K, 250~K, and 200~K. We present that PDF peaks which reflect local atomic arrangements exhibit a noticeable variation below $T_{\rm N}$ without long-range symmetry change. The implication of the PDF evolution is discussed in view of a local structural distortion at the onset of the antiferromagnetic ordering.

The result is a global system of design and making actors localized in community places of Maker Laboratories such as Fab Labs, Makerspaces, Hackerspaces, DIYBio Labs, Repair Cafes and so on. This contribution explores the first maps of the Maker Movement in terms of geographical distribution and of architecture of social networks of its Maker Laboratories and proposes a specific data analysis for each of these two directions. This article draws an overview of the social, local and global nature of the Maker Movement and of its laboratories, with the overall aim to provide spaces for democracy, participation and citizenship.

description: Light induced degradation (LID) due to boron-oxygen (B-O) complexes can cause significant power
loss from high performance p-type mono-crystalline PERC cells. The paper shows that replacing B with Ga as the
dopant in the mono-crystalline silicon can eliminate this degradation. The paper also shows that the continuous
Czochralski (CCz) process enables the production of Ga doped mono-crystalline ingot of very uniform resistivity
distribution, thus, increasing the material yield and lowering the production cost.

Characterisation & Simulation Methods

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 256-261
description: Simulation results are presented that elucidate the role of the interfacial oxide layer in the passivation and carrier selectivity exhibited by doped poly-Si contact layers. An approach is introduced by which the oxide is represented as a layer with limited charge carrier mobility. This approach is easy to implement in numerical simulations and directly affects the conductivity of minority as well as of majority charge carriers, which determine the carrier selectivity. Our results show that for optimal passivation and carrier selectivity the oxide should not be a perfect tunnel oxide but should show higher effective charge carrier mobility. This means that poly-Si/oxide layers with substantial in-diffusion tails can be used, which has benefits when fire-through metallization is applied.

description: In 1991, Negami found an upper bound on the stick number $s(K)$ of a nontrivial knot $K$ in terms of the minimal crossing number $c(K)$ of the knot which is $s(K) \leq 2 c(K)$. In this paper we improve this upper bound to $s(K) \leq \frac{3}{2} (c(K)+1)$. Moreover if $K$ is a non-alternating prime knot, then $s(K) \leq \frac{3}{2} c(K)$.

description: Makerspaces and their various declinations are a widespread initiative of workshops that offer open access to digital and traditional production equipment, with the aim of democratizing access to technologies and supporting bottom-up innovation. They are recognized as a new form of ‘third places’ in a contemporary perspective. As the number of such places grows along with their active communities, business models, contamination projects with universities, companies, and civil society, many researchers have explored the ability of makerspaces to serve as innovation facilitators. Over the last few years, networks and coalitions of makerspaces have started to pop-up with a range of objectives, such as the advocacy and coordination of territorial or project-oriented coalitions; however, they remain largely unanalyzed and undocumented. The paper explores the phenomenon of these networks, drawing on a case study that describes the development of a makerspace regional network in Northern Italy, providing insights concerning its impact on both relationships at a local level and on the acceptance of third places within a regional innovation system, contributing to opening a new field of discussion about the potential of such networked organizations.

Homojunction Solar Cells

description: Interdigitated back contact (IBC) solar cells offer one of the most promising routes towards highest
device efficiencies and have a high potential for low cost production sequences. In this work, we replace typical
patterning steps and high-temperature diffusions in IBC device fabrication by means of laser processing. We report
on the fabrication of a 22.8% efficient all-laser-doped IBC solar cell with localized boron and phosphorus doped
contacts. By means of three-dimensional numerical device modelling we demonstrate that this cell is limited by
recombination at the localized n+ contacts and determine an efficiency potential of 24.5% with improved laser
parameters and surface passivation.

Subjects: policy clinic; translocal; policy making; collaboration

description: The paper sheds light on a university-led cross-innovation approach where the focus is on so-called “Makers” as a distinctive local group. We introduce the format of a policy clinic—comparable to policy innovation labs—as a method to bring different stakeholders from various local contexts under a given thematic topic temporarily together to learn how to initiate new policies for maker spaces. The key thematic interest is to focus on city challenges and approaching so-called “wicked problems.” This requires wide stakeholder engagement by others not present at the event of the policy clinic. The clinic is a temporary trans-local event but is framed by wider participation involvement that starts earlier and is accompanied by a number of approaches before the Policy Clinic event takes place.

description: More than 200 years after von Humboldt's pioneering work on the treeline, our understanding of the cold distribution limit of upright plant growth is still incomplete. Here, we use wood anatomical techniques to estimate the degree of stem cell wall lignification in 1770 plant species from six continents. Contrary to the frequent belief that small plants are less lignified, we show that cell wall lignification in 'woody' herbs varies considerably. Although trees and shrubs always exhibit lignified cell walls in their upright stems, small plants above the treeline may contain less lignin. Our findings suggest that extremely cold growing season temperatures can reduce the ability of plants to lignify their secondary cell walls. Corroborating experimental and observational evidence, this study proposes to revisit existing theories about the thermal distribution limit of upright plant growth and to consider biochemical and biomechanical factors for explaining the global treeline position.

description: The “small unit compound” (SUC) concept [1] allows the preparation of very light weight c-Si solar laminates utilizing thin glass or plastic materials. A main difference to the common module type is the replacement of the frame at the laminates fringe by a lattice-like structure at the rear or at the rear and front side. Due to the small distances between the mechanical supporting elements which prevent the dishing of the laminate, the stiffness of the laminate itself can be reduced to a minimum. This enables the use of thin glass or alternative materials such as
polymer foils. In this paper we present results of mechanical tests with such modules and discuss general results concerning the module lay-out. The paper has a focus on glass/glass and glass/backsheet laminates with glass thicknesses of 0.8, 1.1, 1.6 and 2 mm. A 60 cell glass/backsheet module 0.8 mm front glass with a weight of as low as 6.3 kg (without junction box and cables) has been fabricated. According to our knowledge this is the lowest weight for 60-cell c-Si modules with front glass ever reported. First hail resistance tests show that these modules may surpass
the IEC 61215 norm. Only slightly lower weights are possible if alternative materials are used instead of glass for the
front side cover.
