TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The thick film conductive composition further comprises a metal/metal oxide additive. Preferred Components: The metal/metal oxide additive is selected from: a) a metal where the metal is selected from zinc (Zn), magnesium (Mg), gadolinium (Gd), cerium (Ce), zirconium (Zr), titanium (Ti), manganese (Mn), tin (Sn), ruthenium (Ru), cobalt (Co), iron (Fe), copper (Cu), and chromium (Cr); b) a metal oxide of at least one of the metals selected from Zn, Mg, Gd, Ce, Zr, Ti, Mn, Sn, Ru, Co, Fe, Cu and Cr; and/or c) a compound that can generate the metal oxides of (b) upon firing. The Zn-containing additive is ZnO. The substrate is at least one insulating layers. The substrate comprises at least one semiconductor substrates. The insulating film comprises at least one components selected from: titanium oxide, silicon nitride, silicon compound of formula SiNx:H, silicon oxide, and silicon oxide/titanium oxide.x=not defined.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The dibasic ester is at least one compound selected from dimethyl ester of adipic acid, glutaric acid, and succinic acid. EXAMPLE - A conductive paste composition (test) comprising (wt.%) Ag (76), glass (3.2), zinc oxide (ZnO) (3.7) and organic medium (comprising ethyl cellulose (2.3), viscosity modifier (1.6), dibasic ester-3 (DBE-3) (0.9), TEXANOL (RTM: solvent) (12.1), where DBE-3/organic medium ratio was 0.05) was prepared. Similarly a conductive paste composition was prepared without using DBE-3. The test/comparative composition was used for forming solar substrate and fill factor (FF) was calculated. The test/comparative composition showed FF value of 0.740/0.725 respectively.
