    摘要: Improved protection systems for CIGS-based microelectronic devices of the type incorporating electric conductor(s) such as an electronic collection grid. In one aspect, the present invention relates to a photovoltaic device having a light incident surface and a backside surface. The device includes a chalcogenide-containing photovoltaic layer comprising at least one of copper, indium and/or gallium. A transparent conductive layer is interposed between the photovoltaic layer and the light incident surface, wherein the transparent conductive layer is electrically coupled to the photovoltaic layer. An electronic collection grid is electrically coupled to the transparent conductive layer and overlying at least a portion of the transparent conductive layer. An elastomeric structure having a light incident surface, said structure overlying at least portions of the electronic collection grid and the transparent conductive layer in a manner such that the light incident surface of the elastomeric structure is spaced apart from a major portion of the conductor, and wherein the elastomeric structure comprises an elastomeric siloxane polymer having a WVTR of at least 0.1 g/m2-day. An optional protective barrier overlies the elastomeric structure. The protection systems of the invention incorporate elastomers with water vapor transmission rates that are atypically high in the context of CIGS-based devices.

    摘要: Integrated processes of preparing industrial chemicals starting from seed oil feedstock compositions containing one or more unsaturated fatty acids or unsaturated fatty acid esters, which are essentially free of metathesis catalyst poisons, particularly hydroperoxides; metathesis of the feedstock composition with a lower olefin, such as ethylene, to form a reduced chain olefin, preferably, a reduced chain α-olefin, and a reduced chain unsaturated acid or ester, preferably, a reduced chain α,ω-unsaturated acid or ester. The reduced chain unsaturated acid or ester may be (trans)esterified to form a polyester polyolefin, which may be epoxidized to form a polyester polyepoxide. The reduced chain unsaturated acid or ester may be hydroformylated with reduction to produce an α,ω-hydroxy acid or α,ω-hydroxy ester, which may be (trans)esterified with a polyol to form an α,ωpolyester polyol. Alternatively, the reduced chain unsaturated acid or ester may be hydroformylated with reductive amination to produce an α,ω-amino acid or α,ω-amino ester, which may be (trans)esterified to form an α,ωpolyester polyamine.

    摘要: Crosslinked polydicyclopentadiene polymer and copolymer are made by first forming a thermoplastic polymeric intermediate in a ring-opening metathesis polymerization (ROMP), and then crosslinking the intermediate in a melt-processing or solution processing step. The formation of the intermediate permits facile removal of residual monomer, which leads to a reduction in odor and improvement in physical properties. Crosslinking can be achieved using various crosslinking strategies, including further ROMP reactions, addition polymerization of residual double bonds, addition of a crosslinking agent or introduction of functional groups.
