Si/Zn Dopant GaAs wafer gallium arsenide semiconductor wafer. The ‘germanium on nothing’ approach taken by the team, described in the paper Germanium-on-Nothing for Epitaxial Liftoff of GaAs Solar Cells – published in the journal Joule – involves the creation of a thin layer of germanium on a germanium wafer, and the growth of a GaAs cell on top of the thin layer. For this reason, research addressing cost reduction has been conducted in recent years. The fact that it's a non vacuum, continuous process [with our approach] enables us to be lower in cost than a standard batch semiconductor process.Q: What are the waste products in your process, and how do you treat them? Single-junction solar cells are the most available in the market and the most simple in terms of the realization and fabrication comparing to the other solar devices. Gallium arsenide (GaAs) is one of the most common III-V semiconductor compounds in PV applications. If we were in Silicon Valley, it would have cost a lot more to get where we are today. High cost. Both levels are then peeled off the germanium wafer, allowing it to be reused as a substrate.
