TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Component: The solar cell electrode conductive silver paste comprises (wt.%) high-dispersivity silver powder (53-61), glass adhesive (21.5-31), and organic carrier (15-17.6). The glass adhesive comprises (wt.%) Bi2O3 (46.7-53), ZnO (6.8-8.7), B2O3 (6.7-7.3), Al2O3 (6.5-8.3), SiO2 (11-14.7), CaO (7-8), and TiO2 (6-7.3).n=2-12.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The high-dispersivity silver powder comprises micron silver powder and 40-100 wt.% nanosilver powder.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The ATRP is prepared by adding mercaptoethanol in the solvent A and acrylic reagent under a condition without water and oxygen; stirring at 0-35 degrees C, and adding alpha -bromoacetyl bromide, where the molar ratio of the acrylic reagent to alpha -bromoacetyl bromide to mercaptoethanol is (1-2):(1-2.5):1; stirring and reacting for 1-24 hour at 0-25 degrees C; adding water, and adding methylbenzene to extract; and washing the product with ammonium chloride solution and drying. The mercaptoethanol is HS-(CH2)N-OH. The acrylic reagent is triethylamine, pyridine, or Benzedrine (RTM: racemic mixture of amphetamine). The alpha -bromacetyl bromide is 2-bromopropionyl bromide, 2-bromobutyryl bromide, 2-bromo-3-methylbutyryl bromide, 2- acetoxyisobutyryl bromide, 2-bromural, or 2-bromo-2-methylbutyryl bromide. The solvent A is methylene dichloride, chloroform, methylbenzene, cyclohexane, n-hexane, diethylether, butylene oxide, or carbon tetrachloride. The hydrophobic monomer is styrene, (methyl) methyl acrylate, dibutene, vinyl acetate, vinyl cyanide, or (methyl) glycidyl methacrylate. The catalyst is a low-valence state compound. The aglycone is nitrogen-containing aglycone, phosphor ligand, or halogen ligand. The solvent B is acetone, dimethyl sulfoxide, chloroform, or tetrahydrofuran. The solvent C is tetrahydrofuran, acetone, cyclohexanone, or methyl isobutyl ketone. The solvent D is tetrahydrofuran, acetone, methylene dichloride, or chloroform. The organic carrier is butyl carbitol, propylene glycol methyl ether acetate, ethylene glycol monomethylether, glycol butyl ether acetate, petroleum ether, abies oil, terpinol, castor oil, or cyclohexanone.
