A silicone resin composition contains a cage octasilsesquioxane having a group represented by the following formula (1), an alkenyl group-containing polysiloxane containing an alkenyl group having a number of moles larger than that of a hydrosilyl group in the cage octasilsesquioxane, a hydrosilylation catalyst, and an organohydrogenpolysiloxane. (where, in formula, R1 represents a monovalent hydrocarbon group selected from a saturated hydrocarbon group and an aromatic hydrocarbon group. R2 represents hydrogen or a monovalent hydrocarbon group selected from a saturated hydrocarbon group and an aromatic hydrocarbon group. The molar ratio of the monovalent hydrocarbon group:hydrogen in R2 in the cage octasilsesquioxane as a whole is, as an average value, in the range of 6.5:1.5 to 5.5:2.5.)

A method for producing a silicone resin sheet includes the steps of forming a first coating layer by applying a first silicone resin composition which contains a first organopolysiloxane and a second organopolysiloxane; forming a precursor layer from the first coating layer by reacting the first organopolysiloxane with the second organopolysiloxane so as to have a conversion ratio of 5 to 40%; and forming a second layer on at least one surface in a thickness direction of the precursor layer by applying a second silicone resin composition which contains a third organopolysiloxane, a fourth organopolysiloxane, a hydrosilylation catalyst, and a curing retardant containing tetraalkylammonium hydroxide.

A silicone resin composition contains a first organopolysiloxane having, in one molecule, both at least two ethylenically unsaturated hydrocarbon groups and at least two hydrosilyl groups; a second organopolysiloxane having, in one molecule, at least two hydrosilyl groups without containing an ethylenically unsaturated hydrocarbon group; a hydrosilylation catalyst; and a hydrosilylation inhibitor.

An encapsulating sheet is stuck to a substrate mounted with a light emitting diode to encapsulate the light emitting diode. The encapsulating sheet includes an encapsulating material layer in which an embedding region is defined, the embedding region for embedding the light emitting diode from one side surface of the encapsulating material layer; a first phosphor layer laminated on the other side surface of the encapsulating material layer; and a second phosphor layer laminated on one side surface of the encapsulating material layer so as to be spaced apart from the embedding region.
摘要:
A silicone resin is obtained by allowing a cage octasilsesquioxane having a group represented by formula (1) below, to react with an alkenyl group-containing polysiloxane containing an alkenyl group having a molarity smaller than the molarity of the hydrosilyl group of the cage octasilsesquioxane in the presence of a hydrosilylation catalyst: (where R1 represents a monovalent hydrocarbon group, R2 represents hydrogen or a monovalent hydrocarbon group, and the molar ratio of monovalent hydrocarbon group: hydrogen in R2 in the cage octasilsesquioxane as a whole is, as an average value, in a range of 6.5:1.5 to 5.5:2.5).
摘要:
A wet solar cell module includes two or more photoelectric conversion devices spaced from each other and sandwiched between a first insulating substrate and a second insulating substrate. The photoelectric conversion device includes a first electrode, a photoelectric conversion portion, and a second electrode that are stacked in this order on the first insulating substrate. One of the first electrode and the second electrode included in the photoelectric conversion device has a through portion. Between respective photoelectric conversion portions of two photoelectric conversion devices adjacent to each other, an inter-cell insulating portion extends through the through portion. In a space surrounded by the first insulating substrate, the second insulating substrate, and the inter-cell insulating portion, a carrier transporter is provided.
