<p>PROBLEM TO BE SOLVED: To obtain an adhesive capable of fixing a photovoltaic film and a base together in a short time without the need of mechanically fixing them together, and to provided a method for producing a photovoltaic device for watches using the above adhesive. SOLUTION: This epoxy-based adhesive comprises a main agent made from a bisphenol A-type diglycidyl ether, bisphenol F-type diglycidyl ether and tetraglycidyl diaminodiphenylmethane, a curing agent <=50μm in median particle size dispersed in the main agent and made from an amine derivative >=80 deg.C but <180 deg.C in melting point, an imidazole derivative and a disulfide compound, and 0.5-5.0 wt.% of SiO2 powder. The adhesive is used as a means for fixing together a rigid base constructing the photovoltaic device for watches and a photovoltaic film prepared by forming a photovoltaic layer on an insulation film.</p> |
