Research question

Today’s light-emission technologies depend on critical raw materials (CRMs) and expensive facilities and are in addition difficult to recycle. In this context, our recent demonstration that flexible and thin light-emitting electrochemical cells (LECs) can be fabricated by energy- and material-efficient printing in low-cost facilities using solely CRM-free materials is important. The project goal is now to develop tools for the rational tuning of the LEC-unique dynamic p-n junction doping structure for improved LEC emission efficiency, using sustainable processes and bio-based and/or recyclable materials.
