TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composition comprises the electrically conductive metal (90-95 wt.% of the solids). The thick-film paste further comprises an additive selected from: PbF2, SiO2, Na2O, K2O, Rb2O, Cs2O, MgO, CaO, SrO, BaO, V2O5, Al2O3, ZrO2, BiF3, MoO3, Mn2O3, Ag2O, ZnO, Ga2O3, GeO2, In2O3, SnO2, Sb2O3, Bi2O3, P2O5, CuO, NiO, Cr2O3, Fe2O3, CoO, CO2O3, and CeO2. The organic medium comprises a polymer. The organic medium further comprises at least one additive selected from solvent, stabilizer, surfactant, and thickener. The electrically conductive metal comprises silver. Preferred Method: The firing is carried out in air or an oxygen-containing atmosphere. The thick-film paste composition is applied pattern-wise onto the insulating film.    TECHNOLOGY FOCUS - METALLURGY - Preferred Components: The mole ratio of lead to tellurium of the lead-tellurium-lithium-titanium-oxide is 5/95 and 95/5. The lead-tellurium-lithium-titanium-oxide comprises (wt.%): PbO (25-65), TeO2 (25-70), Li2O (0.1-5), and TiO2 (0.1-5). The lead-tellurium-lithium-titanium-oxide is at least partially crystalline. The lead-tellurium-lithium-titanium-oxide further comprises oxides of at least one element selected from Si, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, V, Zr, Mo, Mn, Zn, B, P, Se, Sn, Ga, Ge, In, Al, Sb, Bi, Ce, Cu, Ni, Cr, Fe, Co, and Ag. EXAMPLE - A frit composition comprising (wt.%) silica (SiO2) (8.40), lead oxide (PbO) (60.90), lithium oxide (Li2O) (1.47), titanium oxide (TiO2) (0.93), tin oxide (SnO2) (0.70), tellurium oxide (TeO2) (27.60) was prepared. A paste (p1) comprising 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (5.57), ethyl cellulose (50-52% ethoxyl) (0.14), ethyl cellulose (48-50% ethoxyl) (0.04), N-tallow-1,3-diaminopropane dioleate (1), hydrogenated castor oil (0.50), pentaerythritol tetraester of perhydroabietic acid (1.25), dimethyl adipate (3.15) and dimethyl glutarate (0.35); and silver was prepared. A final paste comprising the frit composition and the paste (p1) and silver was prepared. The final paste when used in solar cell it showed solar cell efficiency of 14.54%.
