| Sumario: | S2. Redox charge density & thickness: Figure S2. Cyclic voltamogramms of the different P3HT film series with different film thicknesses (indicated by different colors) taken at a scan rate of 20 mV/s. A) P3HT-CHCl3 B) P3HT-THF C) P3HT-CHCl3(NP) D) P3HT-THF(NP). Respective figures E), F) ,G) and H) represent the linear relations found between resulting redox charge densities and measured thicknesses (colors of each film thickness according to the corresponding cyclic voltammogram). Redox charge density values in units of mCcm-2 are calculated by the integration of the anodic and cathodic CV curves for each thickness followed by dividing the obtained values by the scan rate and the probed surface area.-- Figure S3. Transmittance values at 520 nm for the P3HT film series taken in their A) oxidized transparent states and B) neutral colored states as a function of the calculated redox charge density. Symbols represent experimental data points. Lines represent the fitted curves according to exponential decay functions. Regression coefficients r2 are indicated for all the film series. The transmittance curve for P3HT-CHCl3 in the neutral state not only shows overall higher transmittance values but also its exponential fitting curve with lowest regression coefficient strongly deviates from the behavior of all the other films. The different and rather poor transmittance behavior reflects the non-continuous island-like coating of the ITO substrate obtained for this sample by the employed spray-coating process, as demonstrated by the SEM and profilometry results in the main manuscript (Figure 5D and 6D, respectively). The poor transmittance behavior of the spray-coated P3HT-CHCl3 sample in the neutral state thus accounts for the largely different contrast behavior compared to the other P3HT samples, with an apparent shift of the optimum contrast range towards rather high, i.e. out-of-range redox charge density values, as a consequence of unsatisfying fitting results.-- |
