About

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 2011, Alta Devices broke three world records for solar efficiency. Single junction cell performance at 28.8%, single junction module performance at 24.1%, and dual junction cell performance at 30.8%


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.

The Alta Story

Founders

  • 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
    2011

    In 2011, Alta Devices broke both the single cell and module record efficiency at 28.8% and 24.1% respectively. We also broke the dual-junction cell record at 30.8%.

  • 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 Lift Off (ELO), and cell matrix assembly tools.

  • 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.
