Abstract:
A lead-tellurium-lithium-titanium-oxide glass composition is useful as a component of a conductive silver paste. Especially useful are P-containing and V-containing lead-tellurium-lithium-titanium-oxide glass composition. Conductive silver via paste comprising particulate conductive silver and any of the lead-tellurium-lithium-titanium-oxide glass compositions of the invention can be used 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.
Abstract:
The invention describes a composition for sealing agent, generally in the form of glass frit, lead-free, comprising by weight over the total weight of the composition: 30-80% Bi2O3; 2- 10% ZnO; 2- 10% B2O3; 0-5% Na2O; 1- 10% SiO2; 1-8% A12O3; 0-7% BaO; and 0-8% MgO. The composition for sealing agent as defined above can be added with a filler in a quantity up to 20% by weight over the total weight of the resulting mixture. It also describes a sealing paste containing the composition for sealing agent, the possible filler, an organic binder and optionally an organic solvent. It also describes methods for producing the composition for sealing agent and the sealing paste.
Abstract:
