Propriétés Optoélectroniques des composés Chalcopyrites Appliquée aux cellules Photovoltaïques

Abstract

The subject of memory relates to the ab.initio study the properties optoelectronics of chalcopyrites the type I-III-VI2. These materials recently revealed much interest in the community of sciences materials. This study will be based on the theory of the functional calculus the density which, although imperfect, tends to be essential like the standard for the structural analyzes electronic in the community of sciences materials, because it makes possible to obtain good structural and energy predictions. The results so obtained were confronted with the experimental data resulting from the literature
