  • Patent number: 7267713
    Abstract: Provided is a conductive paste capable of adjusting resistivity and forming a conductor film having high strength of bonding with a glass substrate and high mounting strength of a metal terminal. The conductive paste contains a conductive component, a glass frit having a composition containing a Bi2O3—B2O3—SiO2—Al2O3 or Bi2O3—B2O3—SiO2—Al2O3—ZnO primary component and about 0.5 to 5% by weight of NiO as a secondary component, and an organic vehicle. The conductive paste is applied on a glass substrate and then baked to form a conductor film. A glass circuit structure formed by using the conductor film can be advantageously used as a defogging glass for an automobile window.

  • Publication number: 20040055635
    Abstract: A conductive paste used for a rear electrode of a Si solar battery includes an Al powder, a glass frit, an organic vehicle and particles insoluble or slightly soluble in the organic vehicle. The particles are constituted of an organic compound or carbon or both. The conductive paste does not shrink much during firing and, consequently reduces the amount of Si wafer warping while maintaining the functions of a rear electrode for a Si solar battery.
