Germanium-on-Nothing for Epitaxial Liftoff of GaAs Solar Cells

Nothing can bring down the price of III-V solar cells – just add germanium

A research paper from scientists at the U.S. National Renewable Energy Laboratory outlines a new approach to the production of gallium arsenide based cells. The approach, termed ‘germanium on nothing’, could enable the cost effective, high volume production of PV cells based on III-V materials such as gallium arsenide.
