Hanergy And Audi To Integrate GaAs Solar Panels Into Cars


Solar roof will prolong endurance mileage by feeding solar energy into the internal vehicle electrical system

Alta Devices, a subsidiary of Hanergy Thin Film Power Group, has signed a Memorandum of Understanding with Audi AG on strategic cooperation in flexible GaAs thin film cell technology.

Audi and Hanergy will introduce the solution of integrating thin-film solar cells in the panoramic roof of Audi models. It is aimed to prolong the endurance mileage by feeding solar energy into the internal vehicle electrical system - including air conditioning and other electrical appliances.

In the long term, by using technologies from both sides, the two parties plan to gradually transition to use thin film solar technology to feed solar energy into the drivetrain battery to provide additional primary power for vehicles.

The project will not only contribute to Audi's clear vision of emission-free mobility, but also advance the application of thin-film solar technology for global primary energy generation. The two sides plan to jointly present an Audi vehicle prototype featuring an integrated prototype solar roof solution by the end of 2017.

Electric drive systems are essential for future automobiles at Audi. By 2020, the product range will include three battery-electric cars. By 2025, Audi intends to deliver one third of its cars with fully electric drivetrains to customers.

Based on this strategic setting, renewable energy - especially solar energy with the characteristics of mobile energy - has become very attractive for Audi to achieve sustainable mobility.

Since light vehicle bodies and limited vehicle roof areas require solar cells with a high power-to-weight ratio. GaAs, a high-efficient, thin, flexible and lightweight thin film solar technology has therefore stood out as the primary option for Audi's panorama sunroof solution.

Chairman Yuan Yabin of Hanergy remarked at the signing ceremony, "As the automotive industry is striving for green mobility, I believe that the cooperation between the two sides will convey the message of green development to the world through the efforts from the traditional and emerging industries, while revealing the confidence and action from both sides in protecting the environment."

Ding Jian, senior Vice President of Hanergy, CEO of Alta Devices and co-leader of the Audi/Hanergy project, said: "This partnership with Audi is Alta Devices' first cooperation with a high-end auto brand. By combining Alta's continuing breakthroughs in solar technology and Audi's drive toward a sustainable mobility of the future, we will shape the solar car of the future."

"The range of electric cars plays a decisive role for our customers. Together with Hanergy, we plan to install innovative solar technology in our electric cars that will extend their range and is also sustainable," stated Audi board member for procurement Bernd Martens. At a later stage, solar energy could directly charge the traction battery of Audi electric vehicles. "That would be a milestone along the way to achieving sustainable, emission-free mobility," continued Martens.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
