  • Resin composition and an electronic device using the same
    Patent number: 6525261
    Abstract: An electronic device, such as a solar cell, having improved moisture, heat, and wear resistance, formed by applying an insulating film over the surfaces of the electronic device utilizing a screen printing process and curing the film with heat.
    Type: Grant
    Filed: March 14, 2000
    Date of Patent: February 25, 2003
    Assignees: Semiconductor Energy Laboratory Co., Ltd., TDK Corporation
    Inventors: Yuichi Kubota, Yukihiro Isobe, Akemi Takenouchi, Makoto Hosokawa
  • Solar cell and method for producing electrode for solar cell
    Patent number: 5891264
    Abstract: An aluminum film is formed as a photoreflective electrode in the side opposite to the light incident side of a solar cell by sputtering at a substrate temperature of 50.degree. to 200.degree. C. using a target, aluminum containing silicon as an impurity element at 0.1 to 6.0 weight %. An aluminum film or a silver film into which an impurity element is not added is formed on the above aluminum film, to obtain a texture structure having convex and concave shapes. When an organic resin film substrate is used, components (released as a gas by heating and a vacuum atmosphere) such as water within the organic resin film is removed after the aluminum film is formed.
    Type: Grant

  • Resin Composition and an electronic device using the same
    Patent number: 5637156
    Abstract: A resin composition for forming an insulating film suitable for fabricating an amorphous silicon solar cell utilizing a flexible substrate, obtained by mixing a first component comprising a polyfunctional isocyanate compound and a polyol based second component comprising polymers or oligomers having reactive hydroxyl groups which react with isocyanate groups to principally form urethane bonds.
