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. The insulating film is composed of a mixture of two resin components, the first component comprising a polyfunctional blocked isocyanate compound where a dicarbonyl compound is used as a block agent, which dissociates and isocyanate group upon heating, and, a second component comprising a polyol comprising polymers or oligomers having reactive hydroxyl groups which react with isocyante groups to form urethane bonds

Resin composition and an electronic device using the same

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.
