5-6 months - Start in February/April 2025 - Optically active materials and devices can be found in a wide range of energy, environmental and healthcare applications, including semiconductors, photovoltaics, catalysts, sensors and more. To foster an eco-designed manufacturing strategy for the production of these optically active systems with low energy consumption, it is essential to promote the processing of aqueous functional fluids incorporating highly efficient particles, in order to propose a complete architecture printing approach. To this end, EC-LIPSE proposes to address eco-design and the development of innovative sustainable methods for the fabrication of efficient optically active systems (with a first concrete focus on electrochromic devices (ECD)).
