Surface modification of silicon nitride for thick film silver metallization of solar cell

Patent Gonsiorawski, Ronald C.; Xavier, Grace

In the manufacture of a wafer-type silicon solar cell having on its front side a silicon nitride AR coating and an electrical contact that is formed by printing a thick film metal ink onto the silicon nitride in the form of a grid-like pattern having narrow fingers and then firing that ink to convert it to a bonded metal contact, a surface treatment method is provided to adjust the condition of the surface of the silicon nitride coating in a manner that substantially improves the adherence of the thick film ink to the silicon nitride coating, thereby eliminating or substantiallymore » « less

Surface plasmon dispersion engineering via double-metallic AU/AG layers for nitride light-emitting diodes

Patent Tansu, Nelson; Zhao, Hongping; Zhang, Jing; ...

A double-metallic deposition process is used whereby adjacent layers of different metals are deposited on a substrate. The surface plasmon frequency of a base layer of a first metal is tuned by the surface plasmon frequency of a second layer of a second metal formed thereon. The amount of tuning is dependent upon the thickness of the metallic layers, and thus tuning can be achieved by varying the thicknesses of one or both of the metallic layers. In a preferred embodiment directed to enhanced LED technology in the green spectrum regime, a double-metallic Au/Ag layer comprising a base layer ofmore » « less

Electrochemical synthesis of elongated noble metal nanoparticles, such as nanowires and nanorods, on high-surface area carbon supports

Patent Adzic, Radoslav; Blyznakov, Stoyan; Vukmirovic, Miomir

Elongated noble-metal nanoparticles and methods for their manufacture are disclosed. The method involves the formation of a plurality of elongated noble-metal nanoparticles by electrochemical deposition of the noble metal on a high surface area carbon support, such as carbon nanoparticles. Prior to electrochemical deposition, the carbon support may be functionalized by oxidation, thus making the manufacturing process simple and cost-effective. The generated elongated nanoparticles are covalently bound to the carbon support and can be used directly in electrocatalysis. The process provides elongated noble-metal nanoparticles with high catalytic activities and improved durability in combination with high catalyst utilization since the nanoparticlesmore » « less

Lateral electrochemical etching of III-nitride materials for microfabrication

Patent Han, Jung

Conductivity-selective lateral etching of III-nitride materials is described. Methods and structures for making vertical cavity surface emitting lasers with distributed Bragg reflectors via electrochemical etching are described. Layer-selective, lateral electrochemical etching of multi-layer stacks is employed to form semiconductor/air DBR structures adjacent active multiple quantum well regions of the lasers. The electrochemical etching techniques are suitable for high-volume production of lasers and other III-nitride devices, such as lasers, HEMT transistors, power transistors, MEMs structures, and LEDs.

Method of enhancing the wettability of boron nitride for use as an electrochemical cell separator

Patent McCoy, Lowell R [Woodland Hills, CA]

A felt or other fabric of boron nitride suitable for use as an interelecte separator within an electrochemical cell is wetted with a solution containing a thermally decomposable organic salt of an alkaline earth metal. An aqueous solution of magnesium acetate is the preferred solution for this purpose. After wetting the boron nitride, the solution is dried by heating at a sufficiently low temperature to prevent rapid boiling and the creation of voids within the separator. The dried material is then calcined at an elevated temperature in excess of 400.degree. C. to provide a coating of an oxide of magnesiummore » « less
