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.
NREL develops new process to bring ‘Mars Rover’ PV cells down to earth
The U.S. National Renewable Energy Laboratory has developed a process which it says can dramatically reduce the costs of producing ultra-high efficiency cells from gallium arsenide, and other III-V compounds, similar to the solar cells used by NASA in space exploration projects.
