Light-Emitting Electrochemical Cells Become Efficient and Bright
UMEÅ, Sweden, March 7, 2018 — Researchers from Umeå University, Linköping University, and Swedish company LunaLEC AB have developed light-emitting electrochemical cells (LECs) that emit strong light at high efficiency. Using a systematic combination of experiments and simulations, researchers established a generic set of design principles, including balanced trap depths, optimized doping, and electrochemically stabile materials. The researchers' approach has paved the way for LEC devices that emit light
