Alta Devices is (em)Powering the Unplugged WorldTM by delivering the world’s most efficient, thin and flexible mobile power technology. By converting light of any kind into electricity, Alta Devices AnyLightTM power technology extends the energy source of a system, and in many cases, completely cuts the traditional power cord.

Company Highlights

In 2010, Alta Devices first broke the world record for single-junction solar cell efficiency. Since then, Alta Devices has broken the world record six more times (consecutively) and holds the current world record at 29.1%. In 2016 Alta Devices broke the world record for dual-junction cell efficiency at 31.6%.

Single Junction Cell in Hand

In 2012 and 2013, Alta Devices was named to MIT’s list of “Most Disruptive Companies” for its groundbreaking work bringing high efficiency thin film GaAs solar technology to the mass market.

Early Development: 1970 – 2000 

GaAs is first developed by Zhores Alferov in the USSR in 1970. Its superior performance quickly leads to the replacement of silicon based solar panels for space applications. During the 1980’s our founders begin experimenting with methods to commercialize GaAs.

Founding: 2008

Alta Devices is founded with the goal of bringing high efficiency thin film GaAs technology to the masses. The initial goal is to introduce this technology into traditional solar markets like rooftop and utility scale power generation.

Proving Concepts: 2008 – 2011

Alta Devices proves high efficiency thin film GaAs can be grown and mass produced at scale. It is during this time that Alta focuses heavily on research and development.

Breaking Records: 2012

In 2012, Alta Devices breaks the single-junction cell efficiency world record at 28.8%. Alta shifts focus to mobile market applications.

Commercializing: 2012 – 2013

Alta begins building a pilot line for low rate production of GaAs thin film solar cells including building and implementing three unique tools for mass production: high throughput Metal Organic Chemical Vapor Deposition (MOCVD), mass production Epitaxial Lift Off (ELO), and cell matrix assembly tools.

Acquisition: July 2014

Alta Devices is acquired by the renewable energy giant Hanergy Holdings with a portfolio of three other thin film solar companies: Solibro, Global Solar, and MiaSole.

Mass Production: 2015 – Present

The mass production of thin, lightweight, and highly efficient GaAs solar cells will allow Alta Devices to provide its solar technology to both traditional solar and mobile power markets.

Breaking Records: 2016 to Present

Alta breaks the dual-junction cell efficiency world record at 31.6% and the single-junction world record at 29.1%.
