Lighting the Future Sustainably: The Environmental and Economic Potential of Perovskite LEDs

Perovskite light-emitting diodes (PeLEDs) are emerging as strong contenders in the next generation of lighting and display technologies. With advantages such as vibrant color output, lightweight structures, and low-cost fabrication using earth-abundant materials, PeLEDs have attracted significant attention. Yet, their broader environmental and economic impacts have remained insufficiently understood—until now.
