Abstract

This work presents a comparative study of formation energy, crystalline structure, electronic, optical and electrical properties of Na doped ZnO with different positions and concentrations, by using the density functional and Boltzmann transport theories. In this study, we consider two possible configurations of Na doped ZnO: substitution of Zn by Na defects (Na Zn ), and interstitial Na defects (Na i ). We have found that the position of Na has a great effect on physical properties of Na doped ZnO. The formation energy calculation shows that Na doped ZnO in Na i model is more stable that in Na Zn one. The introduction of Na i to ZnO leads to an increase in the transmittance in visible light region while for Na Zn a decrease in transmittance is observed. Na i model shows that the material can be used as a highly transparent conductive electrode. The results show that Na doped ZnO is suitable for photovoltaic device application.
