Hanergy's Alta Devices Hits the High Spot in Solar Energy with Record Breaking Efficiency

Hanergy's GaAs Single-Junction Solar Battery Attains Conversation Rate of 28.9%

Hanergy Thin Film Power Group today announced recently that US's National Renewable Energy Laboratory, one of the world's three largest renewable energy research organizations, has rated its US-based subsidiary Alta Devices' single junction GaAs module as the world's most efficient single-junction solar module. With its record setting 28.9% conversion efficiency, the module can be used to power a range of products from unmanned aerial vehicles (UAV), electric vehicles to smart sensors that were earlier restricted by low efficiency solar solutions.


The group is relentlessly committed to develop technology with well-timed advancements which is bound to hit the high spot. Notably, Alta Devices first broke the record for GaAs single-junction cells in 2010 and has since then broken five conversion efficiency records already. The recent one being Alta's GaAs solar conversion rate of 28.9%, so far the highest efficiency in the world as rated by US's National Renewable Energy Laboratory.

With this most recent breakthrough, Hanergy now has two world records - the record for single-junction batteries (28.9%) and for single-junction battery modules (25.1%) which further fortify the company's position as an undisputed world leader in the field of high-efficiency thin-film solar batteries.

Commenting on the achievement, Mr. Ding Jianru, CEO of Alta Devices said, "Our latest milestone for utmost solar efficiency represents a breakthrough in Hanergy's vision for the future of solar energy applications. More so, at Alta Devices, we believe that with fast-tracking trend towards autonomous machines, it's highly imperative to have sources of power that can be replenished without the interruption. We're aligned with our goal to continue to produce thin-film solar batteries with efficiencies par-excellence to lead the progressing trend towards autonomous machines."

In 2014, Alta Devices, a California-based company became a subsidiary of Hanergy. Extremely efficient, light and flexible, Alta Devices' GaAs thin-film solar panels have been successfully applied to a range of different products.

Last year, Hanergy collaborated with Audi on solar sunroof using GaAs thin film battery technology. Subsequently, Chinese automakers such as FAW and BAIC teamed up with Hanergy to jointly develop GaAs thin-film solar roofs for multiple models. Meanwhile, Hanergy has also brought to use its GaAs thin film solar cells for drones to develop industrial-grade solar drones. Globally, Hanergy holds more than 4,500 patents in the field of thin film solar energy, of which about 50% are invention patents.
