Provided is a pressure sensitive adhesive sheet having a resin layer on a substrate or a release material, at least a surface (&#x3b1;) of the resin layer being opposite to the side thereof on which the substrate or the release material is provided has pressure sensitive adhesiveness, wherein one or more concave portions exist on the surface (&#x3b1;), and a standard deviation (&#x3c3;) based on a mean brightness value of the surface (&#x3b1;) is 10.0 or more. When attached to an adherend, the pressure sensitive adhesive sheet can readily remove air accumulation to be formed and therefore exhibits excellent air escape property, and has good pressure sensitive adhesion characteristics.

Adhesive sheet

Protective sheetfor solar cells comprises a base materialand a thermoplastic resin layerlaminated on at least one surface of the base material. The thermoplastic resin layercomprises a first layerlaminated on the base materialand a second layerlaminated on the first layer. The first layercontains as the main component a copolymer of ethylene and at least one type selected from the group consisting of (meth)acrylic acid, (meth)acrylic acid ester, glycidyl (meth)acrylate and vinyl acetate. The second layercontains an olefin-based resin as the main component. The protective sheetfor solar cells has excellent adhesiveness between the base material and the thermoplastic resin layer and can suppress the warping caused in a solar cell module.

Protective sheet for solar cell, manufacturing method thereof, and solar cell module

A protective sheet for a solar cell module that includes a cycloolefin resin layer laminated to one surface of a substrate film with a polyolefin resin layer disposed therebetween, wherein the polyolefin resin layer and the cycloolefin resin layer are formed by co-extrusion molding.

Protective sheet for solar cell module, and solar cell module

Provided is a protective sheet for a solar cell module having a resin sheet, a vapor deposited layer containing an inorganic oxide provided on at least one side thereof, and a fluorine resin layer containing a silane coupling agent laminated on the vapor deposited layer.
