Metallic contacts for photovoltaic devices and low temperature fabrication processes thereof

摘要: Embodiments of the invention generally relate to photovoltaic devices and more specifically, metallic contacts disposed on devices, such as cells, fabrication processes for forming contacts. The contain a palladium germanium alloy formed at low temperatures during an anneal process. In some embodiments, cell may be heated temperature within range from about 20°Cto 275°Cduring process, example, 150°Cfor 30 minutes. other 150°Cto 275°Cfor time period least 0.5 minutes
