    The thin-film solar cells produced by Alta Devices in the United States are currently the world's most energy-efficient, thinnest and most flexible products
    .
    The company's solar-thin-film cell technology provides devices with an additional source of power by converting light energy into electricity and, in many cases, eliminates traditional power lines
    .
    This thin-film battery technology can be seamlessly integrated into any end electronic product, making it ideal for
    unmanned systems.

    On April 27, the company announced that its next-generation solar cell technology achieved an energy efficiency of 31.
    6%, setting a new world record
    once again.
    This breakthrough will redefine the use of solar cells, especially in
    the drone market.
    Alta technology increases the power-to-weight ratio, which will allow aircraft using this technology to produce more performance
    .
    For example, on a typical high-altitude, long-endurance drone, Alta's solar material requires less than half the area and a quarter of its weight to provide the same amount of energy
    as thin-film technology.
    The space and weight savings allow drone designers to have more design options
    .
    The additional battery on the drone can provide a longer flight time and operational life
    .
    In addition, the load function can be used to provide wireless communication
    at higher speeds and longer distances.
    The optimization of these two designs will bring considerable economic value
    to the UAV operator.

    Rich Kapusta, chief marketing officer at Alta Devices, said: "Our aim has always been to make solar energy an unprecedented configuration and application, and the application of drones will be an important example
    of how this can happen.

    Alta Devices also offers a variety of solar technologies for other applications, including wearables and the Internet of Things (IoT), designed to eliminate battery replacement or charging processes
    .

    Alta Devices achieves the world's highest energy efficiency
    in single-junction solar technology through several breakthrough technologies to manufacture solar cells using gallium arsenide.
    Alta's new double-junction technology builds on the previous single-junction technology, using indium gallium phosphide as the second absorption layer
    on top of the substrate.
    Indium gallium phosphide is more efficient at utilizing high-energy photons than single-junction devices, so the new double-junction technology produces more
    electricity for the same amount of sunlight.
    The company's solar efficiency has been measured and certified
    by the Department of Energy's National Renewable Energy Laboratory (NREL).

    At present, Alta's single-junction gallium arsenide thin-film solar cells have begun mass production
