An electrochromic device can include a substrate; an electrochromic layer or a counter electrode layer over the substrate and including a mobile ion; a first transparent conductive layer over the substrate and including Ag. In one embodiment, the electrochromic device can include a barrier layer disposed between first transparent conductive layer and the electrochromic or counter electrode layer. In another embodiment, the electrochromic device can include means for preventing (1) the mobile ion from migrating into the first transparent conductive layer, (2) Ag from migrating into the electrochromic layer or counter electrode layer, or both (1) and (2). A process of forming an electrochromic device can include forming an electrochromic layer or a counter electrode layer over a substrate; forming a barrier layer; and forming a first transparent conductive layer over the substrate.

This multilayer component () for encapsulating an element () which is sensitive to air and/or moisture comprises an organic polymer layer () and at least one barrier stack (). The barrier stack () comprises at least three successive thin layers (-) 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.

The present disclosure is directed to solar control films containing a photochromic layer. For example, in certain embodiments, a solar control film includes a photochromic layer comprising an inorganic photochromic material and an infrared control layer.

Photochromic solar control films

A luminous glazing unit includes a glass substrate, an additional element that is tinted an optical isolator between the glass substrate and the additional element, a light source, optically coupled to the glass substrate, and a light-extracting device associated with the glass substrate. The optical isolator includes a low-index film, made of fluoropolymer-based material which: has a refractive index n2 at 550 nm such that n1-n2 is at least 0.08, has a thickness e2 of at least 600 nm, is in optical contact with the first main face by a first lamination interlayer, based on a thermoplastic material.

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&#x2267;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.
