The award for Best Innovation went to the Bremer Weser Stadium in Germany because of the innovative combination of transparent polycarbonate sheets and solar cells which enables a roof design that is both visually appealing and environmentally sound. The sheets allow natural sunlight through and utilize solar power to generate energy (e.g. the modules generate 100 Watt of energy per square meter). For this purpose, floating silicon cells are embedded between two plastic sheets made of Makrolon®. Compared to traditional solar modules made of glass Makrolon® sheets are breakproof, can be bended within certain limits and weigh up to two-third less. As the individual sheets can be cut to size, these high-quality modules can be designed to match the style and functionality of the end product perfectly, thus providing architects with new and previously unknown options for harnessing solar energy.
