TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The parent polyolefin comprises repeat units (5-50 wt.%) derived from alpha -olefin comonomer; the alpha -olefin contains 3-10C; and the alpha , beta -ethylenically unsaturated carboxylic acid or anhydride is selected from maleic anhydride, maleic acid, fumaric acid, acrylic acid, methacrylic acid, itaconic anhydride, itaconic acid, citraconic acid, citraconic anhydride, crotonic acid, crotonic anhydride, methyl crotonic acid, cinnamic acid, endo-bicyclo-(2.2.1)-5-heptene-2,3-dicarboxylic acid, endo-bicyclo-(2.2.1)-5-heptene-2,3-dicarboxylic anhydride, cis-4-cyclohexene-1,2-dicarboxylic acid, and/or cis-4-cyclohexene-1,2-dicarboxylic anhydride. The alpha , beta -ethylenically unsaturated carboxylic acid or anhydride is maleic anhydride.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The parent polyolefin has a density of less than or equal to 0.90 g/cc; the parent polyolefin is grafted with 0.03- 5 wt.% of alpha , beta -ethylenically unsaturated carboxylic acid or anhydride; and the grafted polyolefin has a shore hardness of less than or equal to 80. The outermost layer has a thickness of 1-12 mils and at least a portion of the substrate is transparent. The substrate is biaxially oriented polyester film, fluoropolymer film, fluoropolymer-polyester-fluoropolymer film, glass, metal, ceramic, polycarbonate film, acrylic film, polyacrylate film, cyclic polyolefin film, and/or metallocene-catalyzed polystyrene film. The article is the solar cell module having a front light-receiving side and a back non-light-receiving side; the substrate comprises, in the order from the front light-receiving side to the back non-light-receiving side of the solar cell module, an incident layer, an encapsulant layer, and a backing layer; thin film solar cell layer comprises electrically interconnected solar cells is on a surface of the incident layer or of the backing layer; and the outermost layer is the incident layer or the backing layer. The substrate comprises at least one rigid sheet or film layer and at least one polymeric interlayer; the sheet or film is biaxially oriented polyester, fluoropolymer, and/or fluoropolymer-polyester-fluoropolymer. The interlayer adheres to or is in direct contact with the outermost layer. The substrate comprises rigid sheet (preferably glass). The substrate comprises, in the order, a rigid sheet, interlayer, and second rigid sheet or film layer. The incident layer is transparent; the solar cell layer comprises a second substrate having deposited on a layer of thin film solar cell; and the layer of thin film solar cell is adhered to the front encapsulant layer.
