Hanergy GaAs Single Junction Solar Cell Achieves 25.1 Efficiency Record

Hanergy Thin Film Power Group Limited based in Beijing, reported that Fraunhofer ISE CalLab PV Modules, a German solar energy testing laboratory, has rated the newest solar production model from its US-based subsidiary Alta Devices as the highest efficiency single-junction solar module ever produced. With its record-setting 25.1% conversion efficiency, the company says that the module can be utilized to power products including unmanned aerial vehicles (UAVs), electric vehicles, and smart sensors that were previously limited by low-efficiency solar solutions.

Hanergy Says Autonomous Machines Demand Replenishable Power Source

Hanergy asserts that the accelerating trend toward autonomous machines demands a power source that can be seamlessly recharged and has minimal impact on physical form.

“As we move toward a world of autonomous machines, developing sources of power that can be replenished without interruption is increasingly important,” said Alta Devices chief marketing officer, Rich Kapusta. “Each time our technology achieves a new world record, it has been designed with a clear focus on this goal.”

According to Hanergy, the modules perform at up to twice the efficiency of standard flexible solar cells, making them the current world leader in thin film solar technology. The company points out that since 2010, Alta’s GaAs single-junction cells have broken conversion efficiency records four times, and its GaAs Single-junction cells still hold the world’s highest (lab) conversion efficiency rate of 28.8%.

Alta Devices says its thin-film solar panels have been successfully applied to many different products including integrating the solar cells into panoramic glass automobile roofs after work with European car maker. For UAVs, Alta Devices has used the GaAs solar technology to develop a UAV with the longest flight time in the world. Alta Devices says that the extremely light and flexible thin-film panels were easily integrated into the drone without altering its aerodynamic profile.
