Because of long lifetime objectives and cost control, encapsulation is a critical point for the commercialization of perovskite PV technologies. Indeed, degradation mechanisms related to atmosphere ingress requires the use of high gas barrier materials which prevent the diffusion of gases for decades and the development of encapsulation methods which wont damage the devices. In this talk, after introducing the topic, we will highlight some methods we developed in CEA in order to assess encapsulating materials and how it could help to establish efficient encapsulation strategies with a controlled cost.
