There are lots of clever people in the world and some of them work for Armor, a thin-film solar company located in France. One of its products is called ASCA, which uses semi conductor compounds based on organic polymers printed on flexible films. The flexibility means ASCA thin-film solar products can be mounted on curved surfaces, something traditional solar panels cannot do. In tests, it can be rolled and unrolled 50,000 with no loss of performance.
According to the company, ASCA weighs only about 450 grams per square meter. To put that in perspective, it is about 30 times lighter than other technologies. A piece the size of a sheet of paper weighs only 30 grams — about the same as 6 sheets of paper the same size.
Recently, the company demonstrated a car cover embedded with ASCA thin-film solar panels placed over a Gazelle electric car, according to PV Magazine. There is a lot of interest in adding solar panels to electric cars to extend their range but Armor is the first to fit them to a cover for a car instead of to the car itself. The company says its ASCA thin-film products can be incorporated directly into the surface of a car as well. It makes variations of the ASCA thin-film that are resistant to damage from high pressures and pounding.
The thin-film solar panels cover an area of 4 square meters — enough to provide supplementary power to the vehicle and increase its range up to 15 kilometers (9.3 miles) a day based on the car being exposed to the sun for 8 hours. The company has set a target of gaining 30 miles of range (48 km) per day within 3 years.
“With the retractable solar cover, the Gazelle was entirely designed to reduce the carbon impact while traveling,” says a spokesperson for Armor. “The aim of the ASCA organic photovoltaic film is to make tomorrow’s transport more autonomous and less energy-consuming.
Is a solar car cover the perfect solution for all EV owners? Of course not. If you park in a garage at home or at work, it’s not going to be of much use. And it obviously can’t be used in areas where the local slicky boys are likely to walk off with it when your back is turned. But it’s a step forward for the EV revolution, which is a good thing.
I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
