Theoretical insights into kesterite and stannite phases of Cu2(Sn1–XGeX)ZnSe4 based alloys: A prospective photovoltaic material
A comparative study of kesterite (KS) and stannite (ST) phases of Cu2(Sn1−xGex)ZnSe4 (CTGZSe) alloys has been carried out using a hybrid functional within the framework of density functional theory (DFT). Our calculations suggest that KS phase is energetically more stable. We find that the total ene...
