TECHNOLOGY FOCUS - ELECTRONICS - Preferred Property: The electrodes of the solar cell module have thickness of 1-50 microns.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Properties: The average particle size of primary conductive silver powder particles are 0.2-10 micron. The metal-coated secondary conductive particles have average particle size of 0.2-10 microns. The electrode composition further comprises additives (0.01-10) (in parts weight), with respect to primary conductive silver powder particles (100).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The organic solvent is Ethyl cellosolve acetate (RTM: ethylene glycol mono ethyl ether acetate), Butyl cellosolve acetate (RTM: ethylene glycol n-butyl ether acetate), propylene glycol methyl ether acetate, Butyl carbitol acetate (RTM: diethylene glycol n-butyl ether acetate), dipropylene glycol, methyl ether acetate, Butyl carbitol (RTM: diethylene glycol monobutyl ether), propylene glycol monomethylether, dipropylene glycol monomethyl ether, propylene glycol monomethyl ether propionate, ethyl ether propionate, terpineol, texanol, ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, ethylene glycol monomethyl ether, diethylene glycol monomethyl ether, diethylene glycol monomethyl ether, triethylene glycol, triethylene glycol monomethyl ether, triethylene glycol monoethyl ether, propylene glycol monobutyl ether, propylene glycol monomethyl ether, dipropylene glycol methyl ether, methyl ethyl ketone, ( gamma )-butyrolactone, dimethyl amino formaldehyde and ethylene glycol monomethyl ether. The thermosetting oligomer is chosen from acrylic oligomer, meta-acrylic oligomer, acrylic carboxylate, acrylate, epoxy acrylate oligomer (epoxy acrylate copolymer), polyester acrylate oligomer and urethane acrylate oligomer. The thermosetting monomer is (meth) acrylic monomers or epoxy monomers or their mixture, chosen from 30 compounds e.g. methyl methacrylate, ethyl methacrylate, tricyclodecane dimethanol di(meth)acrylate, methyl acrylate and ethyl acrylate. The thermal curing initiator is chosen from benzoyl peroxide and triphenyl methyl chloride.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The binder is chosen from cellulose resin, acrylic resin and epoxy resin.
