Thin films technologies for utility devices

The paper is presenting the efforts developed in INFLPR to improve the thin films technologies to obtain utility products: sensors, photovoltaics, biocompatible coatings for medical applications, etc.A review of the different methods to obtain thin films, which characteristics depend on the technological method used are comparatively discussed. The main interest is focussed on the activities dedicated to achieve solar cells by using new substrates, different than Si and a structure of multilayers in order to improve the efficiency.
