"Electron Leakage" is the Culprit of "LED Droop"?

For a long time, researchers and LED manufacturers have been committed to reducing the losses caused by light emitting diodes (LEDs) to be less efficient, but the real reason behind this phenomenon has yet not identified.

According to the reports on Phys.org, the latest discovery conducted by researchers at Rensselaer Polytechnic Institute will uncover the real reason behind the "LED droop" phenomenon. The discovery is expected to lead a major breakthrough in LED lighting industry's development bottleneck.

A flaw called "efficiency droop" that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to greater electrical currents. Efficiency droop, first reported in 1999, has been a key obstacle in the development of LED lighting for situations, like household lighting, that call for economical sources of versatile and bright light.

It is reported that the researchers confirmed a phenomena known as "electron leakage" as the culprit in a recently published paper.

The researchers said that this discovery provides the first comprehensive model for the mechanism behind efficiency droop, and may lead to new technologies to solve the problem in the future.
