Full textThe goal of this work is to improve the understanding of the experimental suboptimal electrical properties of solar cells based on large bandgap Cu(ln,Ga)Se2 (ClGSe), Le. EG > 1,2 eV and gallium content (xGa=[Ga]/([ln]+[Ga])) higher than 30 %. Ln order to try to answer to the problematic, the work have been focused, firstly, on the implementation of large bandgap ClGSe growth processes by thermal coevaporation and, secondly, on the development of CdS alternative buffer layer based on Zn(O,S) grown by atomic layer de position (AL D, in collaboration with the Uppsala University in Sweden) and reactive sputtering. At high Ga content (xGa rv 50 %), the ClGSe growth and its copper composition seems to be key factors for improving solar cells efficiencies. A model has been proposed in order to better understand the copper content effect at high gallium composition. The adjustment of the Zn(O,S) recipe grown by ALD allowed maximizing devices efficiencies close to 15 %. It is suggested that the control of the Zn(O,S) layer led to the favourable conduction band matching at the interface with the CIGSe. The Zn(O,S) de position by reactive sputtering showed a relative harmlessness for the CIGSe surface

Full textThis thesis is a study in the field of "Spin Caloritronics". This work focuses on the anisotropic magnetothermal transport in ferromagnetic thin film. The aim of this study is to determine the relationship between thermal transport and the magnetization state of the ferromagnetic thin layer. We show the experiments we used to do both electrical and thermal transport measurements. We also present a set of theoretical tools (model, calculation and simulation) which allows a better understanding of the experimental results. The first goal is to define the magnetization state of the sample by the measuring both the magnetoresistance and Hall effect (planar and anomalous). These measurements allow finding all the parameters necessary to the description of the magnetization equilibrium state so that we accurately know the magnetization state of our ferromagnetic thin film. The second goal is to find the angular dependence of thermal transport and to compare it with the angular dependence of electrical transport. To do so, we replace the electric current by a heat current end then do transverse voltage measurements for different angles. The results show that the measured voltage with a heat current has the same behavior as the transverse voltage measured with an electric current

Full textOptical thin films filters have been deposited using plasma techniques onto a shape memory alloy in the aim of activate chromatically bistable mechanical structures with the heat of laser lightening. Several materials in thin films (silicon, silicon dioxide, silver, polymers) have been studied with various experimental techniques and their optical properties have been modeled. Optical filters have been elaborated onto the used shape memory alloy : nitinol. Two kinds of filters have been successfully tested. The first ones transmit the radiation of one laser and reflect the one of the other. The other filters, elaborated with silver and polymer, are more selective, they absorb directly the heat of the selected radiation, while the other radiation is reflected. The elaborated structures have been used as micro-actuators for a bistable mechanical structure, thus we have shown that it is possible to control wireless structures, using heat of laser lightening. Selectivity of the actuation, thanks to the optical filters, is chromatic : each micro-actuator is activated by only one laser radiation. Filters in transmission have shown good stability because no degradation has been observed after 6000 actuation cycles, whereas structures in absorption with silver could be deteriorated due to heating after thousand cycles only

Full textThis work is dedicated to the application of high-performance thin-layer chromatography (HPTLC) for the analysis of plant extracts used in aroma, perfume and cosmetic industries. Different planar chromatographic methods were developed and validated for the quantification of natural compounds in plant matrices: quantification of nicotine in tobacco extracts, quantification of major phenolic compounds in vanilla fruits, beans and extracts and quantification of alcohols and acetates in vetiver extracts from Haiti. A fractionation scheme was developed for chemical separation of the metabolites in oleoresins; HPTLC, by its capacity to focus on specific metabolites, was used for phytochemical screening of the fractions. Fractionation of mate (Ilex paraguariensis St-Hil ) oleoresin allowed for the isolation of saponins enriched fraction which was characterized by HPTLC, HPLC-MS and NMR. 16 saponins were identified; 6 of them were never described in mate leaves. 4 genins were identified as to be ursolic, oleanolic and 23-hydroxyursolic acids as well as 3-hydroxy-24-nor-urs-4(23), 12-dien-28-oic acid, which was never documented. HPTLC and HPLC quantification allowed for the elucidation of 60 to 70 % of the extract and its valorization through its high content in polyphenols and saponins. Developed HPTLC methods were precise, sensitive and repeatable
