Innovative separation processes for pollutants and trace substances, and highly efficient solar cells

The shared goal of achieving the best possible air quality is what links ILK Dresden and ULT AG. As long-standing partners, the two institutions collaborated with other partners in 2011 on a research project focusing on separation processes for pollutant emissions generated during laser processing. This project focused on solutions for the capture of hard-to-filter nanoparticles and materials whose sticky or sublimating emissions quickly clogged the filters used to date. The Institute was responsible for the work involved in the fluid dynamics and process engineering design of the filter and extraction systems.

In 2015, a further research project was carried out in collaboration with partners from industry and research on highly efficient crystalline solar cells based on Metal-Wrap-Through technology (MWT-plus). Here, the ILK Dresden was involved through experimental exhaust air analyses of laser and drying processes and a process evaluation that took energy and environmental aspects into account.

This joint research and development work continued in 2024 thanks to project funding from ULT, which enabled research into the removal of trace substances in new production processes (ASP). The project involved the design and development of technological solutions that enable the capture of specific trace substances from process exhaust air generated during the manufacture of battery cells. Critical trace substances were identified, characterised, and systematically categorised through the analysis of real process exhaust air measurements.
