Effet des structures nanométriques sur le développement des cellules photovoltaïques de troisième génération

Abstract

The purpose of this thesis is to study the effect of the nanostructuring on electrical performance of the third generation inorganic solar cells, in particular all silicon multi-junction solar cells, an abandoned and nontoxic semi-conductor material. To achieve our objective, we have modeled and optimized, in the ideal case the choice of the semiconducting material and the level of its quantum confinement for several inorganic photovoltaic solar cells based on nanostructuring. Then, we have simulated the physical and the electrical parameters, in real case, of all silicon multijonctions solar cells and subsequently optimized their electrical performances. Consequently, we have enhanced the solar cell efficiency at 32,56%.
