Photovoltaic processing is one of the processes that have significance in semiconductor process line. It is complicated due to the no. of elements involved that directly or indirectly affect the processing and final yield. So mathematically or empirically we can’t say assertively about the results specially related with diffusion, antireflective coating and impurity poisoning. Here I have experimented and collected data on the mono-crystal silicon wafers with varying properties and outputs. Then by using neural network with available experimental data output required can be estimated which is further tested by the test data for authenticity. One can say that it’s a kind of process simulation with varying input of raw wafers to get desired yield of photovoltaic mono-crystal cells.

Le but de cette thèse est de répondre à cette question : Le concept de Sacré dans la culture Vodoun serait-il une forme de monothéisme ou une forme polythéisme? La réponse est non, le concept de sacré dans la culture Vodoun n’est ni un monothéisme ni un polythéisme. Ce concept est proche de ce que j’appelle la mono-originalité : Un conglomérat d’énergies à l’origine de tout. Je suis conscient que toute culture prend sa source dans ses conceptions existentialistes, et l’une de ces conceptions est véritablement celle du Sacré. Ce qui me conduit à comprendre le concept du Sacré dans la culture Vodoun et à expliquer à partir de cette conception le comportement et le courant de pensée du peuple Éwé. Le concept de Sacré dans la culture Vodoun serait-il une forme de monothéisme ou polythéisme? Comment une spiritualité qui reconnait n’avoir jamais vu le Sacré et n’a aucune représentation matérielle ou même symbolique du Sacré peut être monothéiste, ou à plus forte raison polythéiste? En partant de l’idée mythologique des Éwé selon laquelle l’énergie originaire de la nature laisserait son empreinte sur toutes les créatures, le concept du Sacré chez les Éwé est le fruit d’une observation de la nature, l’accumulation des expériences, des analyses du cosmos et de toutes ses composantes : il s’agit alors d’un inconnu ou d’un vide. Le peuple Éwé donne le nom Mawu-Ségbolisa à ce vide ou cet inconnu. Le mot le plus juste que je trouve pour décrire ce concept du sacré est la mono-originalité que je définie simplement comme étant : un concept africain du Sacré qui voit une seule énergie de forces à l’origine de tout, et le tout fait cette énergie.

Entre tous les techniques de l’imagerie, imagerie par résonance magnétique (IRM) offre plusieurs avantages en raison de sa faible invasivité, son innocuité et sa résolution spatiale en profondeur, mais souffre d'une mauvaise sensibilité. Pour résoudre ce problème, différentes stratégies ont été proposées, y compris l'utilisation de l’espèce hyperpolarisée comme ¹ ² ⁹ Xe.Le xénon est un gaz inerte avec un nuage d'électrons polarisable qui est très sensible à son environnement chimique. Sa capacité d'être hyperpolarisé permet d'obtenir un gain significatif de la sensibilité. Néanmoins, le xénon n'a aucune spécificité à une cible biologique, par conséquent, il a besoin d’être encapsulé et vectorisée. Des cages moléculaires différentes ont été proposées et nous sommes particulièrement intéressés à cryptophane qui est l'un des meilleurs candidats pour l’encapsulation du xénon.Dans ce contexte, l'objectif de cette thèse est de concevoir des nouveaux cryptophanes qui peuvent être utilisés comme les plates-formes moléculaires pour construire des nouvelles bio-sondes de ¹ ² ⁹ Xe IRM utilisables pour l'imagerie in vivo. Pour cette raison, ces cryptophanes devraient être hydrosoluble et mono-fonctionnalisable.Dans cette thèse, le polyéthylène glycol (PEG) est utilisé pour améliorer la faible solubilité de la cage moléculaire hydrophobe. Il y a également une discussion systématique des façons de casser la symétrie des cryptophanes et les stratégies différentes ont été tentées pour synthétiser cryptophanes mono-fonctionnalisé.En conséquence, plusieurs cryptophanes PEGylés et mono-fonctionnalisés ont été obtenus et leurs propriétés d'encapsulation du xénon ont été testées. / Among all the imaging techniques, magnetic resonance imaging (MRI) offers several advantages owing to its low invasiveness, its harmlessness and its spatial in-depth resolution but suffers from poor sensitivity. To address this issue, different strategies were proposed, including the utilization of hyperpolarizable species such as ¹ ² ⁹ Xe.Xenon is an inert gas with a polarizable electronic cloud which leads to an extreme sensitivity to its chemical environment. Its capacity of being hyperpolarized makes it possible to obtain a significant gain of sensitivity. Nevertheless, xenon has no specificity to any biological target therefore it needs to be encapsulated and vectorized. Different molecular cages were proposed and we are particularly interested in cryptophane which is one of the best candidates for xenon encapsulation.In this context, the objective of this thesis is to design new cryptophanes which can be used as molecular platforms to construct novel ¹ ² ⁹ Xe MRI biosensors usable for in vivo imaging. To meet this demand, these cryptophanes should be mono-functionalizable and enough soluble in water.In this thesis, the polyethylene glycol (PEG) group is used to improve the poor solubility of the hydrophobic molecular cage. And there is a systematic discussion of how to break the symmetry of cryptophanes and different strategies were attempted to synthesize mono-functionalized cryptophanes.As a result, several PEGylated mono-functionalized cryptophanes were obtained and their properties for encapsulating xenon were tested.

To make solar energy mainstream, lower-cost and more efficient power generation is key. A lot of effort in the silicon photovoltaic industry has gone into using fewer raw materials (i.e., silicon) and using more inexpensive processing techniques and materials to reduce cost. Utilizing thinner substrates not only reduces cost, but improves cell efficiency provided both front and back surfaces are well-passivated. In the current work, a kerf-less process is developed in which ultra-thin (~25 [mu]m), flexible mono-crystalline silicon substrates can be obtained through an exfoliation technique from a thicker parent wafer. These substrates, when exfoliated, have thick metal backing which provides mechanical support to the thin silicon and enables ease of processing of the substrates for device fabrication. Optical, electrical, and reliability characterization studies for completed cells show this technology’s compatibility with a heterojunction solar cell process flow. Building on the promising results achieved on exfoliated substrates, further optimization work was carried out. Namely, an improved cleaning process was developed to remove front surface contamination on textured surfaces of exfoliated, flexible mono-crystalline silicon. This process is very effective at cleaning metallic and organic residues, without introducing additional contamination or degrading the supporting back metal used for ultra-thin substrate handling. Spectroscopic studies were performed to qualitatively and quantitatively understand the efficacy of different cleaning procedures in order to develop the new cleaning process. Results of the spectroscopic studies were further supported by comparing the electrical performance of cells fabricated with different cleans. To replace silver as contact metal with a cheaper substitute like nickel or copper, patterning and etching processes are generally used. A low-cost alternative is proposed, where a reusable shadow mask with a metal grid pattern is kept in contact with the surface of the substrate in a plasma-enhanced chemical vapor deposition chamber during silicon nitride deposition. This leaves a patterned silicon surface for selective metal growth by direct electro-deposition. The viability of this process flow is demonstrated by fabricating diffused junction n[superscript+]pp[superscript+] monofacial and bifacial cells and electrically characterizing them. Investigation of the factors limiting the efficiency of the cells was carried out by lifetime measurement experiments. / text

Detailed mapping and geochemical analysis of Oligocene to early Pliocene volcanic rocks in the Little Walker volcanic center, Mono County, California have revealed a complex eruptive history. After eruption of widespread rhyolitic ash flows of the Valley Springs Formation in the Oligocene, Miocene to early Pliocene volcanism of the western Great Basin and northern Sierra Nevada was dominated by eruption of calc-alkalic, andesitic lavas bearing abundant hydrous mafic phenocrysts, and, thus, high H���O contents. These kinds of calc-alkaline magmas are associated with most of the major epithermal Au-Ag districts of the western Great Basin. A highly potassic latitic pulse of volcanism occurred at the Little Walker volcanic center about 9.5 m.y. ago during the ongoing calc-alkalic activity. The latitic series is unusually enriched in K and other incompatible elements, as well as Fe compared to the surrounding calc-alkaline rocks. The latites have mineralogic evidence of much lower H���O content than the calc-alkaline lavas; yet early latitic magmas were rich enough in volatiles to produce very large, welded ash-flow sheets (e.g., the Eureka Valley Tuff). Rapid evacuation of the magma reservoir beneath the Little Walker center during the ash-flow activity resulted in formation of the Little Walker caldera. Intracaldera volcanism culminated with extrusion of viscous, phenocryst-rich plug domes and coulees of transitionally calc-alkaline, low-K latite lava of the Lavas of Mahogany Ridge. The low-K latite series is severely depleted in all incompatible elements relative to early latitic rocks and has mineralogic, geologic, and trace element evidence of higher H���O content relative to early latites. Significant phenocrystic hornblende, association with hydrothermal alteration, and high Eu����� /Eu����� all suggest significant H���O concentration in the low-K latite magmas. These rocks probably come from a source region intermediate between that of the calc-alkaline and latite series. Trace and major element data favor generation of latitic magmas from a primitive mantle diapir. The diapir rose into a subduction zone that was actively generating widespread calc-alkalic lavas throughout the region from hydrous mantle and, possibly, lower crustal sources. The latite magmas were drier and hotter than the calc-alkaline magmas, but were also enriched in volatiles, particularly CO���, and incompatible elements from their undepleted mantle source. Rising latitic magmas may have gained additional incompatible elements by wall rock reaction and zone refining of upper mantle and lower crustal rocks. Extensive qualitative trace element evidence of crystal fractionation shows that incompatible elements may have been further concentrated by variable amounts of crystal settling. High-pressure (plagioclase-poor, pyroxene-rich) fractionation of the early, dry latitic series produced low-Ca-Mg latites with high Fe/Mg and A1���0��� but low Si0���. Low-pressure (plagioclase rich) differentiation of the early latitic magmas produced quartz latite ash flows with high Si0��� and moderate Fe/Mg, while low-pressure differentiation of hydrous low-K latite magmas yielded silicic low-K latite and quartz latite lavas with low Fe/Mg. More extensive separation of olivine relative to pyroxenes at low pressures and increased stability of subsilicic hydrous crystals and Fe-Ti oxides in the hydrous magmas account for changes in differentiation trends caused by Ptotal and PH���O variations. Lack of giant welded ash-flow sheets in the hydrous calc-alkaline series and common eruption of such ash flows from volcanic centers with rather anhydrous magmas led to the conclusion that H���0/CO��� as well as total volatile content are critical controls on the likelihood of large scale, hot ash-flow eruptions. Giant, hot ash-flow sheets and associated calderas are favored in magmas with low H���0/CO��� and high total volatile content. Basaltic and latitic volcanism in areas of thick sialic crust, where crystal fractionation is extensive are, therefore, the best sources of giant ash-flow sheets. H���0/CO��� and total volatile content were also critical controls of the probability of hydrothermal ore deposition. Magmas with high H���0/CO��� and moderate total volatile contents are most favored for ore deposition, because such magmas tend to form mesozonal or epizonal plutons rather than volcanic rocks. Plutonic crystallization of hydrous magma will yield a fluid phase capable of transferring incompatible metals and geothermal heat to ground water. If permeable structures and rocks are present, as in a caldera, widespread mineralization will be favored, but there may be no genetic relation between ore-forming magmas and magmas which produce calderas. / Graduation date: 1980 / For master (tiff) digital images of maps contained in this document contact scholarsarchive@oregonstate.edu
