Figure 8: Decomposition of the time-resolved spectra of (a) neat F8T2 film and (b) F8T2/PC70BM blend films. The upper two panels are magnitudes ( ) and lifetimes ( ) of the fast component. The middle two panels are magnitudes ( ) and lifetimes ( ) of the slow component. The bottom panels are magnitudes ( ) of the constant component. Open symbols indicate that the parameter is fixed in the fitting procedure. Star symbols indicate artificial structures due to the notch filter at 800 nm. D*, CT, and D+ represent PIAs due to singlet exciton, CT state, and carrier, respectively.
