  • Publication number: 20130092225
    Abstract: An electroconductive paste composition, particularly for solar cells, contains silver particles, glass particles, an organic vehicle, and at least one additive. The additive may be tantalum pentoxide or fine, electrically conductive, metal particles, such as gold and/or platinum group metals. When used to form an electrical contact on a solar cell, such a paste provides for enhanced adhesion of the contact to the cell and improved electron transmission.
