Influența tratării termice asupra omogenității de fază și proprietăților de transport în compușii Cu2Zn(SnxSi1-x)Se4, Cu2ZnGeTe4 și Cu2ZnSiTe4 [Articol]

Abstract

In the frame of this study the main attention was put on investigation of phase homogeneity and electrical properties of different quaternary compounds, which are considered perspective for photovoltaics, before and after thermal annealing. As the result, it was found that the number of kesterite phases is much smaller in the annealed samples compared to the non-annealed ones, while no significant influence was found to the electrical conductivity.
