Chemical fine-tuning lifts perovskite LEDs to 37% efficiency

Chemists developed a method to significantly improve perovskite-based light-emitting diodes. The advance, published in Nature, could enable biomedical sensing, low-light imaging and automated facial recognition.

• Perovskite LED efficiency reached 37%
• The method relies on chemical fine-tuning of the material
• Results published in the journal Nature
• Uses include biosensing, low-light imaging and facial recognition
