Rensselaer Researchers Identify Cause of LED "Efficiency Droop"

Voltage at the onset of high injection and voltage at the onset of the efficiency droop (i.e., the peak-efficiency point) as a function of temperature Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: 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.

Supported Project "cyCESH" for Cost-Efficient Printed OLEDs

Schematic structure of an OLED (Credits: cynora) On June 1, 2013, BMBF launched the project cyCESH involving cynora GmbH, Novaled AG and the University of Regensburg with the workgroup of Prof. Dr. Hartmut Yersin. The project is set to run for a duration of three years with a total funding of 6.1 million euros. The research of new soluble materials for the inexpensive production of organic light emitting diodes (Organic Light-Emitting Diodes - OLEDs) and the production of OLED devices with high efficiency are the main focus of the project.

NRL Researchers Discover Novel Material for Cooling of Electronic Devices

Schematic of thermal management in electronics: Local temperature increases occur as a result of current flow in active regions of devices and can lead to degradation of device performance. Materials with high thermal conductivities are used in heat spreading and sinking to conduct heat from the hot regions. (Photo: U.S. Naval Research Laboratory)  A team of theoretical physicists at the U.S. Naval Research Laboratory (NRL) and Boston College has identified cubic boron arsenide as a material with an extraordinarily high thermal conductivity and the potential to transfer heat more effectively from electronic devices than diamond, the best-known thermal conductor to date.
