Abstract:
During solar cell firing, volatile organic compounds (VOC) and a small number of metal particles were removed using the gas flow. When the gas flow was disturbed by the thermal field of infrared belt furnace and structure, the metal particles in the discharging gas flow randomly adhered to the surface of solar cell, possibly causing contamination. Meanwhile, the gas flow also affected the thermal uniformity of the solar cell. In this paper, the heating mechanism of the solar cell caused by radiation, convection, and conduction during firing was analyzed. Afterward, four 2-dimensional (2D) models of the furnace were proposed. The transient thermal fields with different gas inlets, outlets, and internal structures were simulated. The thermal fields and the temperature of the solar cell could remain stable and uniform when the gas outlets were installed at the ends and in the middle of the furnace, with the gas inlets being distributed evenly. To verify the results, we produced four types of furnaces according to the four simulated results. The experimental results indicated that the thermal distribution of the furnace and the characteristics of the solar cells were consistent with the simulation. These experiments improved the efficiency of the solar cells while optimizing the solar cell manufacturing equipment.

Abstract:
Experimental results for solar metallurgy, solar powder metallurgy of titanium, solar surface treatment of titanium and titanium welding are briefly reviewed. Most of them were performed at Plataforma Solar de Almeria Spain using solar furnaces SF5 and SF40 in gas/vacuum furnace. Generally, it was observed that the time to achieve required sample temperature is very short when concentrated solar power used. Thanks to use of renewable solar energy these technologies starts to be attractive for industrial production of titanium in Earth solar belt. It can be expected that the obtained results and approaches are similar also in Space. According to the obtained knowledge, the possible solutions/necessary changes for solar furnaces on Moon, Mars and in main asteroids belt are discussed.

Abstract:
In this manuscript, we will describe the preparation of copper oxide thin films by sol-gel route using solar furnace with area of about 1.5 m2 as a rapid thermal annealing apparatus. The gel films prepared by spin-coating of Cu acetate solution transferred to CuO or Cu2O films after thermal annealing for 1 min employing solar furnace consists of Fresnel lens. The result reveals that the solar furnace can provide enough energy to cause the high temperature reaction of sol-gel route copper oxide synthesis. In addition, the result displays that the solar furnace is preferable apparatus to carry out a kind of high temperature rapid annealing. The oxidization reaction of the gel films significantly depends on the structure of the gel films before annealing. In the case of the gel film which contains little CuO, the film becomes mixture of CuO and Cu2O after the annealing by solar furnace. In contrast, the gel film with CuO structure transferred to pure Cu2O film after the annealing.

Abstract:
La production d’électricité par voie solaire apparait comme la solution la plus prometteuse pour l’avenir, tant en termes de coûts que de pollution. Cependant, afin d’atteindre le niveau de technologie requis pour envisager l’implémentation de telles centrales à grande échelle, plusieurs verrous technologiques et scientifiques sont encore à lever.Dans cette optique, les récepteurs/absorbeurs volumiques pourraient permettre d’atteindre de plus hautes températures que les récepteurs surfaciques (technologie actuellement utilisée dans les tours solaires à concentration), permettant l’usage de cycles thermodynamiques à haute rendement, tels que les cycles Brayton. Via le projet ANR-OPTISOL, la thèse présentée ici veut répondre en partie à ces problématiques par l’étude des absorbeurs solaires volumiques :- Une étude expérimentale des mousses céramiques utilisées comme absorbeur solaire volumique haute température a été menée au laboratoire CNRS-PROMES (UPR 8521). Une expérience a été conçue afin de tester des échantillons de 5cm de diamètre soumis au flux solaire concentré en conditions quasi-1D au foyer d’un four solaire à axe vertical ;- Un code de calcul des transferts thermiques couplés en milieu poreux a été développé utilisant l’hypothèse de « milieu homogène équivalent », puis validé sur les campagnes expérimentales ;- Finalement, un algorithme d’optimisation par essaim de particules a été utilisé afin de déterminer les propriétés géométriques optimales de mousses céramiques maximisant l’efficacité de conversion thermosolaire<br>Solar-to-electricity power plants appear to be the most promises way for large electricity production in the future, in terms of costs as well as environmental impacts. Thus, reaching the required technology level still requires research and innovations in order to implement such power plants at large scale.In this context, volumetric solar receivers/absorbers could allow us to reach higher temperatures in comparison to surface receivers (actual concentrating solar power technology used in solar towers), leading to high efficiency thermodynamical cycles such as Brayton cycles. With the ANR-OPTISOL project, this thesis tends to give new answers on volumetric solar absorbers using ceramic foams:- Experimental studies of open pores ceramic foams used as high temperature volumetric solar absorber have been conducted at CNRS-PROMES laboratory (UPR 8521), with designed of a dedicated experiment for 5cm diameter samples operating under quasi-1D conditions submitted to concentrated solar power at the focal point of a vertical axis solar furnace;- A numerical code has been developed in order to solve coupled heat transfers in porous medium using the “equivalent homogeneous medium” hypothesis, then validated on the experimental campaigns;- Finally, an optimization algorithm has been used (“particle swarm optimization”) aiming the identification of the optimal geometrical characteristics maximizing the solar-to-thermal efficiency of ceramic foams

Abstract:
Pour améliorer la durée de vie des matériaux à haute température et sous atmosphère oxydante, une solution est l’utilisation d’une protection de surface constituée de matériaux ultra réfractaires non oxydes. Un des objectifs principaux de cette thèse est la sélection et la validation expérimentale de nouvelles compositions chimiques de revêtements utilisés en condition oxydante et corrosive à ultra haute température. Les recherches s’appuient sur une démarche expérimentale physico-chimique se basant sur une approche thermodynamique et thermochimique menée au préalable pour choisir les composés. Les revêtements doivent être stables chimiquement, compatibles thermomécaniquement avec le substrat et adhérent de la température ambiante à celle d’utilisation. De plus, Ils doivent jouer le rôle de barrière environnementale et/ou de barrière thermique.Des tests d’oxydation sont réalisés au four solaire sur les systèmes de matériaux non oxydes massifs élaborés par frittage flash. En parallèle, des composites modèles constitués d’une fibre de carbone revêtue par PVD d’un revêtement métallique ultra réfractaire ont été élaborés puis chauffés par effet Joule afin de réaliser des tests d’oxydation. La compréhension des mécanismes entrant en jeu lors de l’oxydation de ces « nouveaux » revêtements est aussi un des challenges de ce manuscrit. Par ailleurs, elle aide à la classification de ces matériaux selon leur résistance à l’oxydation<br>In order to improve material’s lifetime used at a temperature above 2500°C and under oxidizing atmosphere, a solution is to use a surfacing protection constituted of non oxide refractory materials. One of the main objectives of this thesis is to select and experimentally validate new chemical coating compositions which will be used under corrosive and oxidizing atmosphere at ultra high temperature (more than 2000°C). A preliminary thermodynamic and thermo-chemical study aims to select compounds. These compounds are then analyzed with physic-chemical tests. Coatings have to be chemically stable, thermo-mechanically compatible with the substrate and have to stick to the substrate from ambient temperature to more than 2000°C. Moreover, coatings have to act as an environmental barrier and/or as a thermal barrier.Two kinds of oxidation tests are made. On one hand, non oxide massive material’s systems are fabricated by spark plasma sintering in order to be tested at the solar furnace. On the other hand, composite models are fabricated by PVD. A carbon fiber is covered with ultra refractory metallic coating by PVD. Then, these composite models are heated by Joule effect in order to realize oxidation tests. Understanding mechanisms at work during the oxidation of these new coatings is another main objective of this thesis. This understanding will be also useful to classify these materials regarding their resistance to oxidation

In the process, the contact face between the refractory lining and the liquid bath allows interaction between slag and refractory at high temperatures. Corrosion or impregnation of molten metal and slag in refractory depends on factors such as porosity, wetting angle and the reactivity of the slag in relation to refractory solid contact. This study evaluated the effect of slag attack in different refractory applied by ramming made of Al2O3-C-SiC depending on the amount of compression. In addition, a study was conducted `` post-mortem`` of a refractory sample after use in operation. The results allowed correlating the compression efficiency with the effect of corrosion of slag by the static method, and to evaluate the mechanical behavior cold and hot these materials and the influence of chemical composition and particle size of the material. Refractory more easily compression showed the best results for the static slag attack, which highlights the importance of compression efficiency in the field performance of this type of refractory. The analysis of the sample after use in the field demonstrated oxidation and slag penetration-promoting agents as the principal for corrosion in the slag line region.<br>A utilização de massas refratárias de socagem constituídas de Al2O3-C-SiC em fornos cubilôs é constante em processos de fundição. No processo a face de contato entre o revestimento refratário e o banho líquido possibilita a interação entre escória e refratário em altas temperaturas. A corrosão, ou impregnação do metal fundido e escória, no refratário depende de fatores como a porosidade, ângulo de molhamento e a reatividade da escória em relação ao sólido refratário em contato. Neste trabalho foi avaliado o efeito de ataque de escória em diferentes refratários aplicados por socagem constituídos de Al2O3-C-SiC em função da intensidade de compactação. Também foi realizado um estudo ``post-mortem`` de uma amostra de refratário após o uso em operação. Os resultados permitiram correlacionar a eficiência de compactação com o efeito de corrosão da escória pelo método estático, bem como avaliar o comportamento mecânico a frio e a quente destes materiais e a influência da composição química e granulometria do material. Os refratários com maior facilidade de compactação apresentaram os melhores resultados quanto ao ataque de escória estático, o que evidencia a importância da eficiência de compactação no desempenho em campo deste tipo de refratário. A análise da amostra após utilização em campo evidenciou a oxidação seguida de penetração de escória como principais agentes promotores da corrosão na região da linha de escória.

Abstract:
碩士<br>國立臺灣海洋大學<br>光電科學研究所<br>98<br>Zinc oxide (ZnO) nano-tetrapods were deposited on FTO glass substrate at 500 ℃ by furnace method. The samples were used to combine with N-719 or N3 dyes to fabricate two kinds of dye-sensitized solar cells (DSSCs). Under the optimal conditions, an AM1.5 power conversion efficiency of 0.40% was achieved for N3 immersed DSSC and 0.68% was achieved for N-719 immersed DSSC, respectively. SEM images showed that we successfully grew the ZnO nano-tetrapods on FTO glass substrate at 500℃. The X-ray diffraction patterns confirm that the ZnO tetrapods are quasi-aligned predominantly with (002) orientation. The photoluminescence (PL) spectra of the ZnO tetrapods exhibit the near band-edge emission at 3.2 eV with no discernible defect emission, and this confirmed that our ZnO tetrapods are of good crystallinity. The ZnO nano-tetrapods grown at 500 ℃ have larger surface area than the simple one dimensional nanostructures, and then offer the lager area for dye adsorptions. With the larger surface area and higher crystalline quality, the DSSCs based on our ZnO nano-tetrapods show the good overall conversion efficiency.

Abstract:
碩士<br>國立臺灣大學<br>應用力學研究所<br>105<br>We comparatively investigate dye-sensitized solar cells (DSSCs) with Pt-decorated reduced graphene oxides (rGOs) counter electrodes calcined by furnace and atmospheric-pressure plasma jet (APPJ). Pastes that contain chloroplatinic acid solution, rGOs, ethyl cellulose, and terpineol are first screen-printed onto fluorine-doped tin oxide (FTO) glass substrate and then calcined by furnace or nitrogen APPJ. The substrate temperature is set to 510 °C in both cases. Pt nanodots are well distributed on the rGO nanoflakes after furnace or APPJ calcination. Both rGO and Pt can enhance the catalytic effect for reducing I3− to I−.A nitrogen APPJ interacts vigorously with carbonaceous materials in the pastes to enhance DSSC efficiency with a shorter processing time. However, prolonged APPJ-calcination can damage/oxidize rGOs; therefore, for longer processing times, furnace-calcination in turn achieves better DSSC performance. These results agree well with those of electrochemical impedance spectroscopy (EIS) and Tafel experiments.

Abstract:
The correct selection of the operating wavelength is essential for a precise pyrometric temperature measurement on solar irradiated samples, as the measurement may be disturbed by reflected solar radiation. Atmospheric conditions and particularly the emissivity as basic material property determine the amount of this reflected and the emitted radiation from a sample under investigation. An approach to solve this problem by using a monochromator system for temperature measurement in the UV-B range was developed and experimentally tested. With this system, temperature measurements were possible beginning at 1320°C and ranging up to about 2400°C. Two calculation methods are described and compared. The influence of the calibration temperature on the quality of the temperature measurement is shown. Measurements on a blackbody up to 1500°C were performed for calibration purpose. Temperature measurements on a real solar heated magnesia sample up to 2400°C are presented and discussed. These spectral measurements on hot bodies irradiated in the DLR Solar Furnace led to the final specification of the measurement wavelengths to be in the range from 280 nm to 293 nm.

Abstract:
The DLR Solar Furnace in Cologne is a facility that concentrates direct solar radiation with a concentration factor up to 5200. The energy of such concentrated solar radiation can be used to cause thermal or photochemical effects in the irradiated materials. For astrophysical and mineralogical applications a new vacuum chamber with a specific design and instrumentation for solar experiments was developed and installed at the DLR Solar Furnace. This facility enables testing of small samples under high vacuum conditions. Within a project dealing with chondrule formation (chondrules are parts of meteorites) solid samples were melted by concentrated solar radiation. The aim was to investigate and simulate a fast heating-up (“flash heating”) of the samples and a subsequent solidification by controlled cooling. Another experiment series investigates thermal reduction of samples of metal oxide and of lunar regolith simulant. The goal of this activity is to produce oxygen and eventually also pure metals by pyrolysis. The in-situ production of oxygen and metals on the moon is a key technology for future lunar bases or manned Mars missions. The first solar furnace tests within both projects showed the performance of the new vacuum chamber and the feasibility of the different investigation paths.

Abstract:
A 4.2 kW solar furnace heliostat was interfaced with a closed-loop control system to manipulate the azimuth and elevation rotational degrees of freedom to continuously align a solar concentrator with the sun. A QP50-6SD2 quadrant photodiode laser beam positioning device, developed by Pacific Silicon and Sensor, was modified to sense the orientation of the sun. The quadrant photodiode was mounted inside a dark box with a pinhole aperture and mounted so that when the heliostat reflects light along the desired axis, the quadrant photodiode relays balanced error signals. These error signals were interpreted with a Basic Stamp 2p40 microcontroller developed by Parallax Inc. LM741 operational amplifiers and ADC0831 analog to digital converters were used for signal conditioning. The 2p40 microcontroller interprets and checks the error signals every 500ms and uses a ULN2803 Darlington Transistor array to activate the heliostat drive motor’s solid-state relays to maintain solar alignment. The closed-loop heliostat control system can track with 1.6 degrees of accuracy. This is closer than the original prediction of 3 degrees. The control system requires user-inputs for initial alignment. Alignment can initiate with the heliostat out of alignment by at least 6 degrees. The versatility of the 2p40 allows subroutines to be programmed in that can handle hysteresis in the slewing of the heliostat, continue tracking as the heliostat begins to wobble from wind gusts, or continue tracking during intermittent shadowing from clouds.

Abstract:
An existing oil fired furnace was modeled to obtain the maximum swirling of biomass based slurry fuel and air to achieve better combustion of the biomass fuel present in the slurry. For analysis a computational model of the furnace was constructed with a swirl burner placed at the bottom of the furnace using commercially available CFD preprocessing software (GAMBIT). The boundary conditions were set so as to allow biomass slurry and air with different swirl angles with respect to horizontal and vertical planes, with constant velocities of the mixtures. This research work focuses on the effect of different inlet angles of the fuel supply at constant velocity into the furnace for maximum combustion efficiency. Using Fluent, the post process results shows the increase in residence time by 40% with inlet angle of 45 deg with respect to the x and z-axis, 75 deg from positive y-axis and top partially opened, compared to the initial position of the swirl burner placed directly at zero deg. Using non-premixed combustion model the combustion efficiency of the fuel was increased.
