摘要： Paste compositions, methods of making a paste composition, photovoltaic cells, and methods of making a photovoltaic cell contact are disclosed. The paste composition can include a conductive metal component such as aluminum, phosphate glass, phosphorus compounds such as alky! phosphate, and a vehicle. The contact can be formed on a passivation layer on a silicon wafer by applying the paste on the passivation layer and firing the paste. During firing, the metal component can fire through the passivation layer, thereby electrically contacting the silicon substrate.

摘要： 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.
摘要翻译： 包括分散在聚合物粘合剂体系中的一种或多种玻璃料的热熔密封玻璃组合物。 聚合物粘合剂体系在室温下为固体，但在约35℃至约90℃的温度下熔融，由此形成可流动的液体分散体，其可施加到基底（例如盖片和 /或MEMS器件的器件晶片）。 根据本发明的热熔密封玻璃组合物在通过丝网印刷沉积之后快速再固化并附着到基底上。 因此，它们在丝网印刷后不会像常规的溶剂型玻璃料粘合膏一样扩散。 而且，由于根据本发明的热熔密封玻璃组合物不是溶剂型体系，它们在沉积后不需要强力干燥。
