Propriétés électriques des composants électroniques minéraux et organiques. Conception et modélisation d'une chaîne photovoltaïque pour une meilleure exploitation de l'énergie solaire

Abstract : The research carried out in this thesis relates to the mineral, organic electronic components and the photovoltaic systems. Concerning the mineral semiconductors, we modelled the conduction properties of the structures metal/oxide/semiconductor (MOS) strongly integrated in absence and in the presence of charges. We proposed a methodology allowing characterizing the ageing of structures MOS under injection of the Fowler Nordheim (FN) current type. Then, we studied the Schottky diodes in polymers of type metal/polymer/metal. We concluded that: The mechanism of the charges transfer, through the interface metal/polymer, is allotted to the thermo-ionic effect and could be affected by the lowering of the potential barrier to the interface metal/polymer. In the area of photovoltaic energy, we conceived and modelled a photovoltaic system of average power (100W). We showed that the adaptation of the generator to the load allows a better exploitation of solar energy. This is carried out by the means of the converters controlled by an of type MPPT control provided with a detection circuit of dysfunction and restarting of the system.
