摘要： The invention relates to high efficiency diffusion lighting coverings useful in LED lighting applications. The diffusing lighting coverings are made of organic diffusing particles homogeneously dispersed in a transparent polymer matrix. The primary organic diffusing particles are refractive index mis-matched to the matrix polymer. The refractive index contrast between the polymer matrix and diffusion particles, and particle size are selected to provide a high efficiency (minimized particle loading). The high efficiency diffusion coverings provides excellent light diffusion, high hiding properties and high light transmission. The secondary diffusion particles may optionally be added to further improve selected target properties of the covering. Nano-sized ZnO inorganic particles may also function as diffusion particles and optical brighteners as well UV stabilizers. Articles made of this translucent composition are useful in commercial and residential lighting, motor vehicle illumination (lights, panels), street lighting, displays and signs, desktop monitors, and LCD/LED TVs.

摘要： The invention relates to a thin, nano-structured coating that provides optical light efficiency enhancement. The dried coating contains nano-structures that provide a very low haze level of less than 2 percent, and a light transmission improvement of at least 1% over the non-coated substrate. For the nano-structured coating on an acrylic substrate the transmission is greater than 93 percent, and preferably greater than 94 percent. The coatings of the invention are especially useful for optical electronic displays and photovoltaic modules.

摘要： The invention relates to high Tg monolithic and multi-layer thermoformable film or sheet useful as a backsheet on a photovoltaic module (PV). A methacrylic-based material is preferred. The film or sheet is formed of a composition having a Tg greater than 110° C. The methacrylic composition may be a blend of a polymethyl methacrylate polymer and a miscible or semi-miscible high Tg polymer, or may be a copolymer containing primarily methyl methacrylate monomer units. The backsheet is optionally covered with a fluoropolymer or acrylic/fiuoropolymer covering on the outside (side facing the environment). The back-sheet can be clear, white, and/or pigmented. The film or sheet is especially useful in concentrating photovoltaic modules (CPV), and is also useful in thin film photovoltaic modules.

摘要： The invention relates to an acrylic layer (in the form of a coating, film or sheet) useful as part of a photovoltaic module backsheet. The acrylic layer contains at least 40 percent of one or more acrylic polymers, including an acrylic polymer matrix and optionally acrylic impact modifiers. The acrylic polymer is preferably a polymer, copolymer, or terpolymer containing at least 50 weight percent of methylmethacrylate monomer units. The acrylic layer is flexible and optionally contains high levels of white pigment. It may also contain fluoropolymers such as polyvinylidene fluoride to improve weathering, processibility and film formation. The acrylic layer adheres to a polymer support layer such as polyethylene terephthalate (PET). A preferred substrate is PET that is pre-treated to improve adhesion, but unprimed PET can also be used. The backsheet provides excellent weatherability, environmental stability and reflectivity as part of a photovoltaic module.
