Research group at Cornell: A smart approach to enhance UVC LED efficiency

The efficiency of deep ultraviolet light (< 280 nm) emitting diodes (UVC LED) for converting electrical power to UVC photon power (wall plug efficiency) is still low compared to diodes emitting light in the visible spectral region, for instance blue light (50%). A research group at Cornell University, NY has released a promising route for dealing with the basic physics that limits the UVC LED efficiency. According to postdoctoral researcher Moudud Islam, there are three basic problems that limit the efficiency of the UVC LEDs. Read more
