    摘要: Thick film resistor paste compositions, and methods for making the thick film compositions are disclosed. The compositions include a resistor composition dispersed in an organic vehicle. The resistor composition has 3 to 60% by weight RuO2 conductive material, 5 to 75% by weight Ag conductive material, 15 to 60% by weight glass frit and optionally up to 10% by weight copper oxide or precursor thereof, and up to 20% by weight bismuth oxide or precursor thereof. Optionally the glass is (by weight) 25-45% SiO2, 2-15% Al2O3, 0-3% ZrO2, 0-8% B2O3, 5-15% CuO, 0-8% BaO, 0-3% P2O5, and 20-50% Bi2O3. The resistor composition when printed to a dry thickness and fired at a temperature between 750° C. and 950° C. achieves a sheet resistivity between 10 and 10,000 milliohms/square and a hot temperature coefficient of resistivity of 1000 ppm/C or higher. The fired resistor composition may achieve a resistance thickness ratio (Rtr) value between 0.75 and 1.50.

    摘要: A conductive silver via paste comprising particulate conductive silver, a vanadium-phosphorus-antimony-zinc-based-oxide, a tellurium-boron-phosphorus-based-oxide or a tellurium-molybdenum-cerium-based-oxide and an organic vehicle is particularly useful in providing the metallization of the holes in the silicon wafers of MWT solar cells. The result is a metallic electrically conductive via between the collector lines on the front side and the emitter electrode on the back-side of the solar cell. The paste can also be used to form the collector lines on the front-side of the solar cell and the emitter electrode on the back-side of the solar cell. Also disclosed are metal-wrap-through silicon solar cells comprising the fired conductive silver paste.
