Abstract: (1343 Views)
Using the finite element numerical method, we have simulated a planar light emitting diode (LED) based on CH3NH3PbBr3 perovskite material at 530 nm wavelength. Analysis of the LED propagating modes shows that the difference between the refractive indices of the carrier transfer layer and the transparent electrode is a limiting factor for the external quantum efficiency. Moreover, the numerical results indicate that the modes are strongly confined in the middle layer. A further study reveals a similar observation for the second and fourth order modes.
