Figure 4. Identification of parasitic absorption at the resonance wavelength.
Three ZnPc:C60 devices from Fig. 2a with resonances at 910 nm (◼), 950 nm (♦), and 995 nm (◂) are analysed. (a) The experimental device absorption is shown as filled area and the corresponding EQE as hatched area. (b) The simulated absorption is estimated for each layer. The legend entries are given in the order of appearance.
