Abstract:
My PhD discussion will deal with ab initio methods applied to CuIn(S,Se)2 with a view to photovoltaic applications. It will mainly focus on the relevance of these techniques depending on the physics at work. Advanced methods such as GW reveal the presence of a hidden compensating mechanism between lattice distortion and intrinsic defect concentration in CuIn(S,Se)2. Such phenomenon may explain the high efficiency obtained for photovoltaic cells based on Cu(In,Ga)S2 thin film absorbers.
