Charge-transfer resistance of e-P3HT in contact with ferrocenedimethanol solution. Experimental potential-dependent charge-transfer resistance obtained from fits of the impedance spectra (black symbols and line, with error bars indicating the fitting uncertainty), and simulation based on the Marcus–Gerischer model using the experimental DOS from cyclic voltammetry (red line). Simulation parameters (origins described in main text): A = 0.4 cm2, k t = 1.6 × 10−22 cm4 s−1, c red = 6 × 1017 cm−3, λ = 0.6 eV, E 0(FcDM0/+) = +0.07 V vs. Ag/Ag+ or −4.94 eV vs. vacuum (indicated by dashed gray line), T = 298 K
