Alta Devices, founded in 2007 and based in Santa Clara, CA, focuses on high-efficiency solar PV technologies with an emphasis on lowering production costs. Its core technical work targets advanced materials—particularly thin gallium arsenide layers—and manufacturing and form-factor innovations to raise solar conversion efficiency. The company reports lab progress on techniques such as epitaxial lift off to enable efficient use of very thin GaAs layers. Alta’s technologists are addressing efficient raw-material use, improved manufacturing processes, and new ways to optimize conversion efficiency for energy applications. Alta is currently a development-stage company and has raised funding to move toward commercialization; total investment in the current round to date is $72 million. Strong VC and industry investor participation and board involvement aim to support scale-up and commercialization efforts.
