  • Patent number: 10696851
    Abstract: Intercalation pastes for use with semiconductor devices are disclosed. The pastes contain precious metal particles, intercalating particles, and an organic vehicle and can be used to improve the material properties of metal particle layers. Specific formulations have been developed to be screen-printed directly onto a dried metal particle layer and fired to make a fired multilayer stack. The fired multilayer stack can be tailored to create a solderable surface, high mechanical strength, and low contact resistance. In some embodiments, the fired multilayer stack can etch through a dielectric layer to improve adhesion to a substrate. Such pastes can be used to increase the efficiency of silicon solar cells, specifically multi- and mono-crystalline silicon back-surface field (BSF), and passivated emitter and rear contact (PERC) photovoltaic cells. Other applications include integrated circuits and more broadly, electronic devices.

  • Patent number: 8715812
    Abstract: A printed medium having a metallic luster includes an ink-receiving layer on a substrate and a layer of metal oxide particles disposed on the ink-receiving layer. A portion of the ink-receiving layer corresponding to at least one feature includes a non-particulate, light-absorbing colorant dispersed in the ink-receiving layer. An amount of the non-particulate, light-absorbing colorant in the ink-receiving layer portion is sufficient to render a predetermined hue to the metallic luster of the at least one feature. The metal oxide particles have an average diameter of about 3 nm to about 300 nm. The ink-receiving layer has pores that are smaller than the average diameter of the metal oxide particles.
