Stanford's Costly Breakthrough: Next-Gen LEDs Shine Brighter and More Efficiently

Researchers at Stanford University have made significant advancements in the brightness and efficiency of perovskite LEDs (PeLEDs), a cheaper and easier-to-make alternative to traditional LEDs. By replacing 30% of the perovskite's lead with manganese atoms, the team more than doubled the brightness and almost tripled the efficiency of the PeLEDs. However, these enhancements also caused the lights to degrade and fade within minutes of use. The researchers are now working to find a way to mitigate this degradation while maintaining the improved efficiency, in order to develop a viable commercial solution.
