Ab initio Calculations of the Electronic Properties of CuIn(S,Se)2 and other Materials for Photovoltaic Applications
Résumé
In the first chapter of this thesis, we will present the principle of PV solar cells with a special emphasis on the CIS absorber. In the second and third chapter, we will describe the methods we used to treat the many body problem. Finally, in the last chapter, we will apply methods presented in chapter 2 and 3 to CIS and pay a particular attention to the dependence of the bandgap on the anion displacement and the concentration of defects.
