Abstract: The invention is directed to a polymer sheet and its use as part of a solar panel and glass element. The sheet comprises multiple coextruded polymer layers, wherein at least two or more layers of the polymer sheet comprise a luminescence downshifting compound for at least partially absorbing radiation having a certain wavelength and re-emitting radiation at a longer wavelength than the wavelength of the absorbed radiation, and wherein a luminescence downshifting compound in a first polymer layer can absorb more radiation at a lower wavelength than the luminescence downshifting compound present in a next layer.

Abstract: The present invention relates to a multilayer film for the encapsulation of photovoltaic cells, comprising: (a) at least a first, outer thermoplastic polymer layer;(b) a second thermoplastic polymer intermediate layer arranged between the first and the third layer, and (c) a second, outer thermoplastic polymer layer, wherein at least one of layers (a), (b) or (c) is opaque.

Abstract: Provided herein are light weight glass laminates having ionomeric interlayers and at least one glass layer. In particular, the weight of the glass laminates is reduced by reducing the thickness of the at least one glass layer to about 2.0 mm or less, or to about 1.5 mm or less. The light weight laminates retain favorable performance properties such as have good Pummel adhesion levels, good moisture resistance, and low stress. Further provided are lightweight glass laminates equipped with integral mounting devices.

Abstract: A solar cell module comprising a solar cell layer and a sheet comprising at least one layer of a sodium ionomer composition, wherein the sodium ionomer composition consists essentially of a sodium ionomer that is an ionic, neutralized derivative of a precursor ?-olefin carboxylic acid copolymer, wherein about 10% to about 35% of the total content of the carboxylic acid groups present in the precursor ?-olefin carboxylic acid copolymer have been neutralized with sodium ions, and wherein the precursor ?-olefin carboxylic acid copolymer comprises (i) copolymerized units of an ?-olefin having 2 to 10 carbons and (ii) about 20 to about 25 wt %, based on the total weight of the ?-olefin carboxylic acid copolymer, of copolymerized units of an ?,?-ethylenically unsaturated carboxylic acid having 3 to 8.
