Thanks to their good electroluminescence efficiency, there is increasing interest in organic light-emitting electrochemical cells (LECs) as solid-state luminescence sources. New research reveals how to further improve efficiency and what limits lifetime of this optoelectronic device.
Generating light either from electrical energy or chemical reactions, LECs hold great promise for diverse applications such as large-area lighting. Despite the technology's high potential for smarter energy management compared to incandescent light bulbs, limited device lifetime and efficiency hold back widespread use.
