Firms sign MOU to develop vehicles overlaid with high-efficiency solar cells; prototype expected by end of 2017.Alta Devices, a subsidiary of solar-cell specialist, Hanergy Thin Film Power, will work together to integrate solar cells into “panoramic” glass roofs of certain Audi electric models.
By this cooperation, the partners are aiming to generate solar energy to increase the range of Audi electric vehicles. The project announcement, released this week, says that the first prototype will be developed by the end of 2017.
As the first step, Audi and Alta Devices will integrate solar cells into a panoramic glass roof. In the future, because Alta’s technology is flexible, thin, and efficient, almost the entire roof surface is planned to be covered with solar cells.
The electricity generated from the cells will flow into the car’s electric system and can supply, for example, the air-conditioning system and seat heaters – a gain in efficiency that has a direct positive impact on the range of an Audi electric vehicle.
“The range of electric cars plays a decisive role for our customers. Together with Alta Devices and Hanergy, we plan to install solar technology in our electric cars that will extend their range and is also sustainable,” said Dr. Bernd Martens, the Member for Procurement on Audi’s Board of Management. At a later stage, the partners propose, “solar energy could directly charge the traction battery of Audi electric vehicles”.
Dr. Martens added, “That would be a milestone along the way to achieving sustainable, emission-free mobility,” continued Martens. The green electricity will be generated by Alta Devices’ innovative solar cells. These solar cells are very thin and flexible, hold the world-record for efficiency, performing extremely well in low light and high temperature environments.”
Alta and Audi
Audi claims to be a leader in the premium electric vehicle market with plans to bring three battery-powered electric vehicles to market by 2020. Demand for electric cars is increasing worldwide due to emissions standards, consumer preferences and technological advancements. Vehicle range is a key differentiator for electric car consumers in both the premium and non-premium markets.
Alta Devices says that demand for its technology will significantly increase through this application in the consumer vehicle market. The company stated, “This development is expected to accelerate our global manufacturing expansion and scale-up. This will increase our competitiveness in all markets including Small UAV, HALE UAV and Space applications.”
