Alta Devices, a subsidiary of Hanergy Thin Film Power Group will work with Audi to manage to integrate thin-film solar cells into a panoramic glass roof.At a more advanced stage, the two companies aim to come up with a way of covering the entire rooftop with solar cells. The ultimate aim is for the electric vehicle to gain efficiency, with the electricity generated feeding the car’s electrical system or, for example, the air-conditioning system or the seat heaters- a development that is expected to have a direct positive impact on the car’s range.
Dr. Bernd Martens, Audi Board of Management Member for Procurement said: “The range of electric cars plays a decisive role for our customers”. He added: “Together with Hanergy, we plan to install innovative solar technology in our electric cars that will extend their range and is also sustainable”.The true revolution though will be when the electricity produced will be able to directly charge the traction battery. “That would be a milestone along the way to achieving sustainable, emission-free mobility”, Dr. Martens said.
