Project Overview
Positive Impact: EERE supported the development of Alta Devices' thin-film gallium arsenide photovoltaic technology that set a world record for conversion efficiency.
Locations: Santa Clara, California, and Sunnyvale, California
Partners: Alta Devices
EERE Investment: $3 million
Clean Energy Sector: Renewable electricity generationPDF

Partnering with Alta Devices of Santa Clara, EERE supported the development of the company's  gallium arsenide photovoltaic technology that set a world record for thin-film conversion efficiency. Alta Devices' pilot production line in Sunnyvale is expected to be completed in 2013. The company uses a pioneering technique that allows it to produce incredibly thin, flexible layers of gallium arsenide. Venture capital and private equity investment in Alta Devices now totals more than $120 million.

Since 2007, EERE’s SunShot Incubator has invested $92 million in 54 solar startups that have attracted more than $1.7 billion in venture capital and private equity investments. The Incubator program provides early-stage assistance to help startup companies cross technological barriers to commercialization while encouraging private investment.

The Solar Energy Technologies Office (SETO) focuses on achieving the goals of the SunShot Initiative, which seeks to make solar energy cost-competitive with other forms of electricity by the end of the decade.
