Abstract

This layered element (11) for encapsulating an element (12) that is sensitive to air and/or moisture, especially an element that collects or emits radiation such as a photovoltaic cell or an organic light-emitting diode, comprises a polymer layer (1) and a barrier layer (2) against at least one face (1A) of the polymer layer. The barrier layer (2) has a moisture vapor transfer rate of less than 10−2 g/m2 per day and consists of a multilayer of at least two thin hydrogenated silicon nitride layers (21, 22, 23, 24) having alternately lower and higher densities.
