The layered element (11) comprises a polymer layer (1) and a barrier layer (2) against at least one face (1A) of the polymer layer for encapsulating an air and/or moisture sensitive element (12), Especially components that collect or emit radiation, such as photovoltaic cells or organic light-emitting diodes. The barrier layer (2) has a water vapor transfer rate of less than 10 -2 g/m2/day and consists of at least two thin layers of hydrogenated silicon nitride (21,22,23,24 ) of multilayer composition. |
