By integrating these nanostructures into white OLEDs, an external quantum efficiency
of up to 76.3% can be achieved.
measured an external quantum efficiency
exceeding unity for PbSe nanorods .
Relative uncertainties in responsivity, and the correlation coefficients between them, are identical to those of the external quantum efficiency
. Figure 2 is a contour plot of the correlations between the values at different wavelengths (the unity values of self-correlation have been removed).
To further reduce the production cost and enhance the performance of these LEDs, there is always a great need to improve the external quantum efficiency
(EQE) and solve the efficiency droop.
Figure 3 shows the total reflectance spectra and external quantum efficiency
(EQE) of the GaAs solar cells with and without the InGaP conical frustum nanostructures.
In this regard, in Figure 7 the simulated external quantum efficiency
(QE) is presented for 1 sun illumination condition.
However, the external quantum efficiency
(EQE) of LEDs, which is defined as the product of internal quantum efficiency and light-extraction efficiency, is still required to be further improved.
