The group, led by Basel professors Catherine E. Housecroft and Edwin C. Constable, see LECs as potentially advantageous compared to LED because they are simpler devices with a single layer of active material, which can be solution-processed in ambient conditions.
Until now, LECs have had short life, which prevented exploration as a viable lighting technology. The research group have demonstrated that devices with lifetimes of 2,500 hours can now be prepared.
