Barrier films including a (co)polymeric substrate, at least one dyad on the substrate, each dyad made of a (co)polymer layer and an oxide layer overlaying the (co)polymer layer, and an outer (co)polymer layer overlaying the dyads. Optionally, at least one outer oxide layer overlays the outer (co)polymer layer. The barrier films transmit visible light and transmits, at an incident light angle of at least one of 0°, 30°, 45°, 60°, or 75°, at most 70 percent of incident ultraviolet light at a wavelength range from at least 100 nanometers to 400 nanometers or in a wavelength range from at least 100 nm to 350 nm. The barrier films exhibit atomic oxygen degradation of less than 1×10mg/atom. The barrier films may be applied to decorative objects or electronic devices, (e.g., light receiving or emitting devices, in a satellite or aircraft. Methods of making the barrier films also are disclosed.

According to one embodiment, a solar device, comprises one or more photovoltaic cells disposed in an encapsulant and a light control structure including a louver film having a series of louver structures, wherein each louver structure includes one or more groupings of a plurality magnetizable particles aligned at least in a first orientation dispersed in a binding matrix. The light control structure substantially transmits light incident at a first angle and substantially limits transmission of light incident at a second angle. Each louver structure is spaced apart from an adjacent louver structure, wherein each louver structure is substantially aligned in a plane substantially parallel to an adjacent louver structure.

Methods of making the same are also disclosed. 

A process for making a barrier film having a substrate, a base polymer layer applied to the substrate, an oxide layer applied to the base polymer layer, and a top coat polymer layer applied to the oxide layer is provided. An optional inorganic layer can be applied over the top coat polymer layer. The top coat polymer layer is formed by vapor depositing and curing cyclic aza-silane and acrylate monomer. The use of a silane co-deposited with an acrylate to form the top coat layer of the barrier films provide for enhanced resistance to moisture and improved peel strength adhesion of the top coat layer to the underlying barrier stack layers.

Moisture resistant coating for barrier films

An assembly that includes a barrier film interposed between a first polymeric film substrate and a first major surface of a pressure sensitive adhesive layer is provided. The first polymeric film substrate has a first coefficient of thermal expansion that is, in some embodiments, up to 50 parts per million per Kelvin. The pressure sensitive adhesive layer has a second major surface opposite the first major surface that is disposed on a second polymeric film substrate. The second polymeric film substrate is typically resistant to degradation by ultraviolet light. In some embodiments, the second polymeric film substrate has a second coefficient of thermal expansion that is at least 40 parts per million per Kelvin higher than the first coefficient of thermal expansion. The assembly is transmissive to visible and infrared light.
