  • Conductive silver paste for a metal-wrap-through silicon solar cell
    Patent number: 9246030
    Abstract: A conductive silver via paste comprising particulate conductive silver, a vanadium-phosphorus-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.
