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 four more times (consecutively) and holds the current world record at 28.8%. In 2016 Alta Devices broke the world record for dual-junction cell efficiency and holds the current world record at 31.6%.

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

Early Development 1970 – 2000 

GaAs was first developed by Zhores Alferov in the USSR in 1970. It’s superior performance quickly led to the replacement of silicon based solar panels for space applications. During the 1980s our founders began 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 was to introduce this technology in traditional solar markets like rooftop and BiPV. We would not shift our focus to mobile markets until 2012.

Proving Concepts 2008 – 2011

We began by proving that high efficiency thin film GaAs could be grown and mass produced at high efficiencies. It was during this time Alta operated more like an extension of University research.

Breaking Records 2012

In 2012, Alta Devices broke the single-junction cell efficiency world record at 28.8%. We also broke the dual-junction cell efficiency world record at 31.6% in 2016.

Commercializing 2012 – 2013

After proving the technology was possible, we began building our pilot line for low rate production of GaAs thin film solar cells. It was during this time we built and implemented three unique tools that allow us to mass produce thin film GaAs: Our high throughput Metal Organic Chemical Vapor Deposition (MOCVD), mass production Epitaxial

Acquisition 2014

In July 2014, Alta Devices was acquired by the renewable energy giant Hanergy Holdings. We joined a portfolio of three other thin film solar companies: Solibro, Global Solar, and MiaSole. As of 2015, we are listed as a part of Hanergy Thin Film Solar Group on the Hong Kong Exchange.

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.
