TECHNOLOGY FOCUS - ELECTRONICS - Preferred Cell: The organic photovoltaic layer contains an electron acceptor material and an electron donor material. The polyolefin containing panel is selected from an organic photovoltaic cell, liquid crystal display panel and/or light-emitting diode panel.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The electron acceptor material is selected from fullerenes, oxadiazoles, carbon nanorods, discotic liquid crystals, inorganic nanoparticles, inorganic nanorods, and/or polymers containing moieties capable of accepting electrons or forming stable anions. The transition metal is selected from manganese, iron, cobalt, nickel, copper, rhodium, and/or ruthenium; and the transition metal salt is selected from cobalt benzoate, cobalt oleate, cobalt stearate, cobalt 2-ethylhexanoate, cobalt octanoate, cobalt neodecanoate, cobalt acetylacetonate, cobalt 2-ethylbutyrate, cobalt acetylacetonate, and/or cobalt 2-ethylbutyrate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The antioxidant is 2,6-di(tert-butyl)-4-methylphenol, 2,2'-methylene-bis(6-tert-butyl-para-cresol), triphenylphosphite, tris-(nonylphenyl)phosphite, vitamin E, tetra-bismethylene 3-(3,5-ditertbutyl-4-hydroxyphenyl)-propionate methane, and/or dilaurylthiodipropionate. The adhesive layers comprise ethylene-vinyl acetate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The oxygen scavenger composition is incorporated into the at least one substrate selected from polyethylene, polyethylene terephthalate, polyethylene naphthalate and/or polyimide. The electron donor material is discotic liquid crystals, polythiophenes, polyphenylenes, polyphenylvinylenes, polysilanes, polythienylvinylenes, and/or polyisothianaphthalenes. The oxygen scavenger composition further comprises transition metal and/or transition metal salt; an antioxidant; trigger mechanism that is capable of initiating the oxygen scavenging when triggered by an event; and UV trigger that is capable of initiating the oxygen scavenging when triggered by exposure to UV light. The substrate comprises polyolefins-based overwrap, where the oxygen scavenger composition is present in the polyolefins-based overwrap as an oxygen scavenger layer. The polyolefins-based overwrap comprises an oxygen scavenger layer situated between two barrier layers, where the two barrier layers are situated between two adhesive layers that are situated between two polyolefin layers. The oxygen scavenger layer is selected from ethylenically unsaturated polymers, ethylene methylacrylate cyclohexenylmethyl acrylate terpolymer, ethylene vinyl cyclohexene copolymer, ethylene cyclohexenylmethyl acrylate copolymer, cyclohexenylmethyl acrylate homopolymer, ethylene vinyl toluene copolymer and/or ethylene propylene diene terpolymer.
