Résumé     
We have investigated the impact of Mo density onto Mo/CIGSe interfaces. In this study, CIGSe layers have been simultaneously co-evaporated onto different Mo/soda-lime glass (SLG) substrates. Varying the Mo layer density allows to tune the amount of sodium available during CIGSe growth. The chemical composition of the Mo/CIGSe interfaces has been investigated by X-ray photoelectron spectroscopy (XPS) after lift the CIGSe layer off the molybdenum. Na and Ga amount on the Mo side are correlated to the Mo density. The CIGSe morphology is also impacted by Na amount. Two different chemical environments of sodium are distinguished for the fine-grained CIGSe.
