Alta Devices was founded in 2007 by Eli Yablonovitch and Harry Atwater and manufactured solar photovoltaic applications for mobile devices that enable the conversion of light into electricity. The firm was acquired by Hanergy Group, a privately held Chinese multinational renewable energy company, in 2013[5]

Adoption

The firm's technology is significant for unmanned aerial vehicles (UAVs), solar cars, and other electric vehicles.'[6] NASA has been testing its solar technology for the International Space Station. The firm has been working with Audi on 'solar roofs' for their automobiles.[7]

Previous records

The firm has previously broken efficiency records for single-junction solar cells and solar modules.[6]
