At the KIT Open Day 2017 the photovoltaics experts at IMT organized a Solar Car Race. The event attracted a lot of visitors, who got the chance constructing their own solar-powered electric cars. During the day, young and old showed great enthusiasm assembling and optimizing their cars. To compete with others, the young solar car engineers were able to race their self-build cars on a test track. While the kids where busy racing, the parents had to chance to learn something about our research on renewable energy. The overall response to the Solar Race was overwhelmingly positive. Thanks to everybody who helped!!!
