Resin composition and an electronic device using the same

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
