Guodian Photovoltaic GaAs solar cells achieve 34.5% efficiency

Recently, the reporter learned that Guodian Photovoltaic Technology has made new breakthroughs and the flexible thin-film gallium arsenide battery passed the German Fraunhofer ISE testing agency (one of the world's three most authoritative testing organizations).

After testing, Guodian Photovoltaic flexible thin film gallium arsenide cell conversion efficiency reached 34.5% (AM1.5G), which is the highest efficiency flexible thin film solar cell reported in the world. Through the unique technology independently developed by Guodian Photovoltaics, the manufacturing cost of this battery is more than 50% lower than traditional high-efficiency gallium arsenide batteries, and it can provide sustainable energy with the best cost performance for aviation equipment, mobile electronic equipment, wearable equipment, and Internet of things equipment. power.

Intergrated Led Emergency Modules

The Intergrated Led Emergency Modules is match the compact LED fittings to improve the emergency function. Normally it is workable for small wattage from 3-60W LED panels, downlights, led tubes, tri-proof ceilings. Full power output or half power emergency output is optional. Customized emergency lighting time is available. Automatic lighting up when main power failures. Widely using for home, parking lot, office, building, warehouse, school, hospital, workshop etc.
