Abstract of CRADA work: 

NREL and Ampulse will engage in cooperative research to develop III-V photovoltaics on alternative 

substrates.

Summary of Research Results: 

• Developed high-quality molecular-beam epitaxy grown III-V solar cells using both front/back 

and all-front contact schemes. Front contact schemes are necessary for eventual use in III-V cells 

grown on insulating substrates.

• Developed selective etching of arsenide-based alloys.

• Performed initial growth and characterization of III-V on template/oxide substrates.
