  • Illumination is responsible for approximately 20% of global electricity consumption, a figure that could be reduced to 5% if all light sources consisted of light-emitting diodes (LEDs).
  • Our most recent breakthrough is one step on the way,” says Feng Gao, professor at the Department of Physics, Chemistry and Biology at Linköping University.
  • Blue perovskite-based LEDs have previously been created with using what is known as the “quantum confinement technique,” which gives low-intensity LEDs with poor efficiency.
