| 20090101190 | Solar Cell Contacts Containing Aluminum And At Least One Of Boron, Titanium, Nickel, Tin, Silver, Gallium, Zinc, Indium And Copper - Formulations and methods of making solar cell contacts and cells therewith are disclosed. In general, the invention provides a solar cell comprising a contact made from a mixture wherein, prior to firing, the mixture comprises at least one aluminum source, at least one source of a metal including one or more of boron, titanium, nickel, tin, gallium zinc, indium, and copper, and about 0.1 to about 10 wt % of a glass component. Within the mixture, the overall content of aluminum is about 50 wt % to about 85 wt % of the mixture, and the overall combined content of boron, nickel, tin, silver, gallium, zinc, indium, copper, is about 0.05 to about 40 wt % of the mixture. | 04-23-2009 |
| 20090220799 | Method Of Making Multilayer Structures Using Tapes On Non-Densifying Substrates - A method of applying a ceramic coating to a substrate comprises laminating one or more layers of a green ceramic tape to a rigid substrate using a tackifying resin to adhere the tape to the substrate. Upon firing, the tackifying resin ensures near zero shrinkage of the tape in the XY plane without usage of elevated pressures or temperatures during lamination of green tape to the substrate. The thermal degradation completion temperature of the tackifying resin is lower than that of the resin binder used in the green tape. | 09-03-2009 |
| 20100096598 | METHOD OF MAKING SOLAR CELL CONTACTS - Formulations and methods of making solar cells are disclosed. In general, the invention presents a solar cell contact made from a mixture wherein the mixture comprises a solids portion and an organics portion, wherein the solids portion comprises from about 85 to about 99 wt % of silver, and from about 1 to about 15 wt % of a glass component wherein the glass component comprises from about 15 to about 75 mol % PbO, and from about 5 to about 50 mol % SiO | 04-22-2010 |
| 20100163101 | Thick Film Conductor Formulations Comprising Silver And Nickel Or Silver And Nickel Alloys And Solar Cells Made Therefrom - Formulations and methods of making solar cells and solar cell contacts are disclosed. In general, the invention presents a solar cell contact made from a mixture wherein the mixture comprises a metal portion, which, prior to firing, comprises nickel and silver. | 07-01-2010 |
| 20100173446 | Layered Contact Structure For Solar Cells - Formulations and methods of making semiconductor devices and solar cell contacts are disclosed. The invention provides a method of making a semiconductor device or solar cell contact including ink-jet printing onto a silicon wafer an ink composition, typically including a high solids loading (20-80 wt %) of glass fit and preferably a conductive metal such as silver. The wafer is then fired such that the glass frit fuses to form a glass, thereby forming a contact layer to silicon. | 07-08-2010 |
| 20110169108 | Hot-Melt Sealing Glass Compositions And Methods Of Making And Using The Same - Hot-melt sealing glass compositions that include one or more glass frits dispersed in a polymeric binder system. The polymeric binder system is a solid at room temperature, but melts at a temperature of from about 35° C. to about 90° C., thereby forming a flowable liquid dispersion that can be applied to a substrate (e.g., a cap wafer and/or a device wafer of a MEMS device) by screen printing. Hot-melt sealing glass compositions according to the invention rapidly re-solidify and adhere to the substrate after being deposited by screen printing. Thus, they do not tend to spread out as much as conventional solvent-based glass frit bonding pastes after screen printing. And, because hot-melt sealing glass compositions according to the invention are not solvent-based systems, they do not need to be force dried after deposition. | 07-14-2011 |
| 20110186787 | Electrically Conductive Polymeric Compositions, Contacts, Assemblies and Methods - Electrically conductive polymeric compositions adapted for use in forming electronic devices are disclosed. The compositions are thermally curable at temperatures less than about 250° C. Compositions are provided which may be solvent-free and so can be used in processing or manufacturing operations without solvent recovery concerns. The compositions utilize (i) fatty acid modified epoxy acrylate and/or methacrylate monomer(s) and/or oligomer(s), (ii) fatty acid modified polyester acrylate and/or methacrylate monomer(s) and/or oligomer(s), or combinations of (i) and (ii). Also described are electronic assemblies such as solar cells using the various compositions and related methods. | 08-04-2011 |
