The study aims to investigate the electronic and optical properties of two types of oxides in their stable phases (the co-doped ZnO and BiYO3, the simple and composite compound) in order to build a new sufficient solar cell transparent electrodes. This work may contribute to the development of solar cell electrodes by the exploitation of the optoelectronic properties of these compounds. This study is made with the numerical techniques ab initio based on the DFT that we will describe in more details in this chapter. The result was found to show that the transmittance of BiYO3 and the simple oxide treated is significant (about 90% for the simple oxide), bandgap varies and the behavior of the conductivity is ensured by the presence of an important concentration of electrons.
