Der volle Inhalt der QuelleThis work is for the purpose to develop a new solar concentrating technology. It covers the presentation of the concept, the prototype realization and the optical and energy study of a new solar concentrator QingSun™. This concentrator has a shape of rectangular parallelepiped and includes linear Fresnel lenses, mirror-lined walls and a mobile solar receptor controlled by a tracking system inside the casing. An optical model and an energy model were developed and validated with a series of experiments. The both models permitted us to examine the function and the energy performance of the concentrator. A parametric study of the influence of the tilt and the orientation was performed and showed that the tilt had more influence than the orientation. Finally, the optimal energy performance of this concentrator was estimated

Der volle Inhalt der QuelleNext-generation solar cells consist of thin-films of different materials stacked-up. The purpose of those layers is to extract and transport free charge carriers generated by the absorption of the solar spectrum. Engineering layers in a solar cell consist in maximizing the separation of the charge carriers and their extraction towards electrodes, and limiting their recombination. Surface states, energy level alignement between materials and potential at interfaces dictate the behavior of photogenerated charge carriers in solar cells, which is responsible for the performance of devices. Properties of different surfaces and interfaces in organic and perovskite solar cells are explored in my thesis work. In a first study, I present the properties of an electron transport layer extensively used in organic and perovskite solar cells, titanium dioxyde, prepared at low temperature and at the interface with organic molecules. In a second study, I present my results regarding the integration of FAPbI3 perovskite nanocrystals (PNC) in solar cells. The characterization of optoelectronic properties of PNC and their evolution at the interfaces with an electron transport layer (TiO2) and hole transport layer (MoO3) are presented. Photoemission spectroscopy techniques are used to reveal the energy levels and electronic properties of the different systems. The different results obtained in this work allow for a better understanding of the energetic and chemical landscape at the interfaces between the mentionned materials, and thus explains the behavior of charge carriers in the associated cells

Der volle Inhalt der QuelleDirect steam generation concentrated solar power plants use the optical concentration of solar direct irradiation to generate high pressure and high temperature steam in the absorber tubes. Steam is used as the working fluid of a Rankine-type thermodynamic cycle for the propelling of a steam turbine and an electric generator. The conjunction of the natural transient condition of solar irradiation and the presence of a two-phase flow inside the absorber tubes leads to a strong dynamic behavior of the steam generation system. Moreover, steam turbines being very sensitive to inlet temperature transients, the control of steam generation has to be achieved with the best possible efficiency. Because of the large time constants of the flow in the solar field (among other reasons), basic control strategies are poorly efficient and not well suited. The aim of this thesis work is the study, through modeling and simulation, of the dynamic behavior of the steam generation system. Dynamic modeling of linear Fresnel and parabolic-trough solar plants is carried out, and experimental data from a parabolic-trough prototype are used for validation. The models are used for the study of advanced control strategies, for a better control of steam conditions at the solar field outlet, under irradiation transients. Short-term irradiation prediction methods are evaluated for a use in the control strategies

Der volle Inhalt der QuelleCollecting and storing solar energy in chemical energy is a highly desirable approach to solve energy challenge. The great potential of a photoelectrochemical cell technology combines the harvesting of solar energy with the water splitting into a single device. 2D semiconducting nanosheets of Transition Metal Di-Chalcogenides (TMDC) are seen as an attractive material to design an efficient photocatalyst for the conversion of solar energy into hydrogen. Despite the unique optoelectronic properties of the TMDCs, the passivation of surface defects in high concentration is a remaining challenge for the development of this class of materials. In this context, the present work has aimed the elaboration of thin 2D TMDC photocatalyst for solar water splitting. The development of high performance photocatalysts was evaluated following two main axis. A first strategy consists in the surface defects passivation of 2D p-WSe2 nanosheets using Mo-S complexes to decrease the photogenerated charge carrier recombination and improve photocatalytic activity. We demonstrated these Mo thio and oxo-thio- molecular complexes films as an ideal class of catalysts, well-suited to functionalize 2D materials since they are stable in aqueous environments, cheap and environmentally benign. Current densities of -2 mA cm-2 at -0.2 V vs NHE electrode were obtained for the new p-WSe2/MoxSy photocathode. Besides developing high electro-catalytic activity, the Mo complexes films were shown to display ability to heal surface defects. The respective contributions in catalytic and healing effects observed experimentally for the various molecular Mo complexes involved strong adsorption on point defects of the 2D WSe2 substrate of Mo complexes such as (MoS4)2-, (MoOS3)2-and (Mo2S6O2)2-. The Mo complexes films spontaneously formed at well-defined pH were demonstrated to present n-semi-conducting behaviour and band engineering formed with p-WSe2 showed to be suitable for ensuring charge separation and efficient migration of the photo-induced electrons for the Hydrogen Evolution Reaction, thus representing an example of multicomponent passivation layer exhibiting multiple properties. A second strategy focus in the nanostructure optimization of WSe2 with high specific surface area and pore walls composed of few layers. Nanostructured WSe2 films of high surface area and good charge carrier collection were obtained by co-assembling WSe2 nanosheets and reduced graphene oxide (rGO) nanosheets with an optimal rGO/WSe2 nanosheet ratio. After deposition of co-catalyst thin layer, the new layered nanojunctions of rGO-WSe2/MoxSy exhibited photocurrents up to -5 mA cm-2 at -0.2V vs NHE. Incident-photon-to-current efficiency conversion of 10% were achieved for WSe2 nanoflakes of 70 nm thickness in presence of rGO and MoxSy co-catalyst.[...]

Der volle Inhalt der QuelleIn this thesis, voltage measurements provided by the advanced metering infrastructure (AMI) are used to control an on-load tap changer located at the secondary substation. The thesis presents a practical and a straightforward method of selecting the low voltage customers whose voltage measurements are used as an input to the controller of the on-load tap changer. The developed method takes into account the load and the topology of the network. Furthermore, a simple method of creating synthetic and statistically correct load curves for networks studies is presented. The created methods have been tested by using real data of low voltage networks on a common platform in the power distribution industry leading to encouraging results; a few customers per low voltage network should be monitored in order to achieve accurate voltage measurements.This methodology is further applied to estimate the hosting capacity of photovoltaic power generation in a given low voltage network.In the first part, the evolution of the hosting capacity by using three different types of voltage control; an on-load tap changer of five and nine tap positions and voltage control through photovoltaic power generators, is studied. The study considers two different cases for placing and sizing the photovoltaic generators in a low voltage network. The results of 38 low voltage networks are provided.In the second part, the hosting capacities of 631 low voltage networks, located in a French metropolitan area, are analysed by using an on-load tap changer of five and an on-load tap changer of nine tap positions.The work has been together with Électricité Réseau Distribution France (ERDF), the major French distribution system operator. All studies presented in the thesis are based on the real operational data of the company. Moreover, all studies are implemented on a platform that is widely used in the power distribution industry.As an introductory part to low voltage networks, the thesis provides a general view about the French power system. In addition, the thesis presents a number of selected technologies considering low voltage networks that seem promising in the future

Der volle Inhalt der QuelleIn this work, different nanostructured catalytic systems have been synthesized by an organometallic approach to produce nanoparticles (NPs) of small size and narrow size distribution, and their catalytic activity in the water oxidation reaction has been evaluated. First Fe NPs stabilized by oleic acid were synthesized that displayed an average size of ca. 10 nm ± 1.1 nm. A gamma-Fe_2O_3 oxide layer ca. 2.6 nm thick has been formed at their surface to obtain Fe@FeOx core-shell structure of ca. 11.5 ± 2.3 nm in diameter. Despite their hydrophobicity, these nanoparticles showed good electrocatalytic activity in alkaline conditions. As the gamma-Fe_2O_3 oxide shell is well adapted to the grafting of phosphonic groups, these Fe@FeOx NPs were grafted with different aminophosphonic acids in order to transfer them into water. Preliminary assessment of their catalytic activity showed improved activity for the NPs functionalized by 3-aminopropylphosphonic acid which opens promising prospects. Subsequently, a Ru-phenanthroline light-harvester with a pendant phosphonate group was synthesized and grafted onto the Fe@FeOx core/shell NPs to afford a novel hybrid photoanode for solar-driven water splitting. Mono- and biphasic processes were investigated to graft the Ru-complex at the surface of the NPs. The monophasic process was found to be more efficient as it provided a higher grafting density at the surface of the NPs (respectively 56 and 9 Ru per nanoparticles for the mono and biphasic processes). Photoelectrochemical measurements showed that the hybrid nanocatalyst comprising the highest Ru content was ca. 9-fold more catalytically active than a simple mixture between a ruthenium polypyridyl photosensitizer bearing no grafting group and the Fe@FeOx nanoparticles, and 40-fold more active than the pristine Fe@FeOx NPs. The performance enhancement could be attributed to a more efficient electron transfer between the ruthenium polypyridyl photosensitizer and the Fe@FeOx water oxidation catalyst thanks to the covalent bonding between these two components. The covalent grafting was found to improve not only the photocatalytic activity but also the stability of the system. Finally, amorphous NiFe NPs (diameter ca. 4 nm) with two different ratios between Ni and Fe (Ni_0.5Fe_0.5 NPs and Ni_0.68Fe_0.32 NPs) were synthesized, oxidized in air and grafted with 3-aminopropylphosphonic acid in order to obtain hydrophilic systems. The electrocatalytic activity of these water-soluble NPs was studied in alkaline solution, in comparison with that of crude NiOx NPs, FeOx NPs, and Ni_0.1Fe_0.9Ox NPs. The water soluble NPs containing 32 % of Fe (Ni_0.68Fe_0.32Ox) showed the highest activity and a good durability in alkaline solution. These characteristics make these amorphous NPs potentially applicable in photoelectrochemical cells for water splitting

Der volle Inhalt der QuelleThe traditional vertically integrated power systems are changing towards a smarter ones with the high presence of renewable technologies, distributed generation (DG), greater energy efficiency and electric vehicles. Solar PV is the technology with the highest share among residential DG systems, due to several reasons among them: falling costs, increase of energy conversion efficiency and scalability features. The present thesis presents an investigation on the dynamics of residential PV adoption in Brazil. In the first chapter, I investigate how electricity tariffs structured as volumetric charges affect residential PV adoption under a net metering scheme in Brazil, a developing country and an emerging DG market. A two-ways fixed effects panel data regression covering 4,995 municipalities over the period of 2013-2017 is employed. Since the explanatory variable shows a high content of zero-valued observations, I use the PPML estimator to run the regressions. The main result is that for each one BRL cent of tariff increase, there will be an expansion of about 5.3\% in new residential PV projects in the following year.In the second chapter, I investigate the determinants of residential PV adoption in an emerging country context using social, economic and environmental variables. The analysis is realized using a dataset in census sector level with 310,120 observations, with 42 covariates. Territory fixed effects are applied in the municipality-level. The main results show that 21 covariates are statistically significant and that most of them may be related to income distribution issues in some degree. Therefore, net metering incentive mechanism had a positive influence to boost residential renewable energy generation, mainly PV technology. However, those who benefit from the incentive are wealthier people, which does not make sense in respect to social justice, because those who indeed need to be subsidized in order to reduce the electricity bills and increase the purchasing power are the underprivileged population.Finally, in the third chapter, I examine the relationship between certain socioeconomic covariates and PV market diffusion in the municipality level. I conduct a two-stage empirical analysis. At first, I use the Bass technology diffusion model to estimate the innovation and imitation coefficients. For that, I build the $q/p$ ratio to represent a risk aversion index to each respective municipality's adoption rate over time. In the second stage, I run regressions based on the PPML estimator, due to the non-gaussian nature of the dependant variable, to investigate associations between the risk aversion index and different socio-demographic and economic covariates. The results show evidences of the association of PV technology risk aversion and households socioeconomic characteristics. This behavior may be based on several assumption as regulatory uncertainty, technology information and easy to understand rules for average customers etc

Der volle Inhalt der QuelleThis work on the improvement of solar protection according to an eco-participatory concept proposes 2 parts, (i) the elaboration of a simple formulation, (ii) the synthesis of substitute melanin. The formulation contains only 8 ingredients, including 2 organic filters selected on their photostability, physicochemical characteristics, and absence of impact (health, ecosystems), BEMT and DHHB. Total protection is achieved by the addition of lignosulfonate (LiS), a widely available, non-toxic, anti-free radical, and a water-soluble polymer. Experimental design allowed to minimize the concentrations, resulting in 2 stable formula, SPF30 and SPF50, containing 9 and 12% filters respectively, and 5% LiS each. From the observed booster effect, hypotheses on LiS-filter interactions were proposed. The second part concerns the production of pyomelanin. While the quantities produced by the microorganisms remain low, 3 processes are compared: autooxidation of HGA-Mn2+ (yield 0.317 g/g substrate), an induced culture of Halomonas titanicae (0.55 g/L), and a method based on a laccase polymerization (PyoENZ, 1.25 g/g). The 3 structures had been characterized by 13C NMR (CP-MAS) and FTIR, a partial biological decarboxylation reaction was occurred and led to the formation of gentisic alcohol and gentisaldehyde which are incorporated in the polymer. PyoENZ is hyperthermostable, non-(photo)cytotoxic, traps ROS, effectively reduces Fe3+, and is proposed for applications

Der volle Inhalt der QuelleThis work consists of the experimental and numerical study of the energy performance of a prototype of solar micro-cogeneration. The facility, located on the campus of the University of La Rochelle, operates by coupling a 46.5 m² parabolic trough solar collector field with an oil-free piston steam engine operating according to the Hirn thermodynamic cycle. The solar tracking system is carried out in two axes and the water is evaporated directly into the absorber of the parabolic trough collectors. Electricity generation is provided by a generator and the recovery of fatal heat must make it possible to meet the heating and domestic hot water needs of a building. The first part of this work presents the tests performed. The objective is to carry out additional tests to characterize the solar concentrator, to study the conditions of steam overheating, as well as the operation of the complete installation in winter. This work has allowed the development of models for the parabolic trough sensor, the tests in overheated mode have shown the need for an extra charge for the operation of such an installation while the tests with motor present productions compatible with the electricity and heat consumption of a residential building. The second part concerns the modelling of the elements constituting the micro-cogenerator as well as the integration of this installation into the building using dynamic thermal simulation software (TRNSYS©). This study proposes two integration options depending on the positioning of the auxiliary heater. For both configurations, weekly and annual reviews are presented to discuss the advantages/disadvantages of each provision. It appears that the positioning of the auxiliary on the primary circuit makes it possible to control the electrical production. The addition of back-up boiler on the distribution seems more easily achievable but prevents the control of power generation
