    摘要: A stacked photoelectric conversion device (100) includes an intermediate transparent conductive layer (3) and a thin-film photoelectric conversion unit (2) which are disposed on a crystalline silicon-based photoelectric conversion unit (4) provided with texture on the light-receiving surface thereof and equipped with a crystalline silicon substrate (42). An average morphology height of the texture on the light-receiving surface of the crystalline silicon photoelectric conversion unit is preferably 0.5 µm or more. The intermediate transparent conductive layer is formed so as to fill recesses of the texture on the light-receiving surface of the crystalline silicon-based photoelectric conversion unit, and cover tops of projections of the texture.

    摘要: The present invention, in one aspect, relates to a fabric for arc-protective garments including first yarns and second yarns different from the first yarns. The first yarns include first modacrylic fibers, and the first modacrylic fibers contain an infrared absorber in an amount of 2.5 wt% or more inside the fibers with respect to a total weight of the fibers. The weight of the infrared absorber per unit area in the fabric for arc-protective garments is 0.05 oz/yd 2 or more. The present invention further relates to an arc-protective garment that includes the fabric for arc-protective garments. Thus, the present invention provides the fabric for arc-protective garments and the arc-protective garment that include modacrylic fibers and that can exhibit high arc resistance even when the basis weight is low.

    摘要: The object of the present invention is to provide a polyol composition in which a core-shell polymer is uniformly dispersed in a large amount in a polyol having a high molecular weight, and a thermosetting resin (for example, polyurethane resin and epoxy resin) containing the polyol composition and having excellent mechanical properties (for example, toughness and tensile strength).
    The polyol composition of the present invention contains a polyol composition containing a first polyol (A-I) having a number average molecular weight of 1000 to 10000 and a core-shell polymer (B) having a volume average particle diameter of 0.01 to 0.6 µm, wherein an amount of the core-shell polymer (B) is 35 to 60 % by weight per 100 % by weight of the polyol composition, the core-shell polymer (B) is uniformly dispersed in the first polyol (A-I), a polymer constituting a shell layer of the core-shell polymer (B) has a solubility parameter of 9.30 to 10.20 (cal/cm 3 ) 1/2 , and the polymer constituting the shell layer is polymerized with at least 25 to 90 % by weight of an alkyl (meth)acrylate having a linear or branched alkyl group of 4 to 10 carbons.
