Short description (English)

Advanced solid state dye sensitized solar cells based on Sefar precision fabrics

Abstract (German)

Harvesting solar power is an important pillar for guaranteeing future clean and renewable energy. Hereby, dye sensitized solar cells have the potential to replace the more expensive silicon technology. In the previous CTI project, EPFL and Sefar AG have developed a novel metal wire precision fabric electrode for the use in cheaper dye sensitized solar cell modules, leading to high efficiencies of over 6%. Those modules employed a liquid electrolyte which is lacking robustness important for the expected long livetimes of these devices. Therefore, to further propel market maturity of our successfully devised precision fabric solar cell, our aim is to carry our technology over to more robust solid state dye sensitized solar cell modules in the extension of this CTI project.
