Abstract: This multilayer component (11) for encapsulating an element (12) which is sensitive to air and/or moisture comprises an organic polymer layer (1) and at least one barrier stack (2). The barrier stack (2) comprises at least three successive thin layers (21-23) having alternately lower and higher degrees of crystallinity, the ratio of the degree of crystallinity of a layer of higher degree of crystallinity to the degree of crystallinity of a layer of lower degree of crystallinity being greater than or equal to 1.1.

Abstract: A device includes an organic polymer layer and an electrode positioned against the polymer layer, the electrode being constituted by a transparent stack of thin layers including an alternation of n thin metallic layers and of (n+1) antireflection coatings, with n?1, where each thin metallic layer is placed between two antireflection coatings. At least one of the two antireflection coatings located at the ends of the constituent stack of the electrode includes a stack that is a barrier to moisture and gases, the layers of the or each barrier stack having alternately lower and higher densities.

Abstract: The subject of the invention is a process for obtaining a material comprising a substrate coated on at least one portion of at least one of its faces with a stack of thin layers comprising at least one silver layer, said process comprising a step of depositing said stack then a heat treatment step, said heat treatment being carried out by irradiating at least one portion of the surface of said stack using at least one incoherent light source for an irradiation time ranging from 0.1 millisecond to 100 seconds, so that the sheet resistance and/or the emissivity of said stack is reduced by at least 5% in relative terms, the or each silver layer remaining continuous at the end of the treatment.

Abstract: This multilayer component (11) for encapsulating an element (12) which is sensitive to air and/or moisture comprises an organic polymer layer (1) and at least one barrier stack (2). The barrier stack (2) comprises at least one sequence of layers consisting of a retention layer (22) sandwiched between two high-activation-energy layers (21, 23), in which: for each of the two high-activation-energy layers (21, 23), the difference in activation energy for water vapor permeation between, on the one hand, a reference substrate coated with the high-activation-energy layer and, on the other hand, this same reference substrate when bare is greater than or equal to 20 kJ/mol; and the ratio of the effective water vapor diffusivity in the retention layer (22) on a reference substrate to the water vapor diffusivity in this same reference substrate when bare is strictly less than 0.1.
