which it is built. Consequently, the support has a very strong influence on the structural properties of the layer deposited thereon.

Much work already exists in the context of optimizing the performance of CIGSe cells with various materials as a buffer layer. It is in this tertiary perspective that this work is also part of, that is to say to seek the optimized properties of the material used as a buffer layer and to control the micro-activities behind performance losses.
