Figure 6: Decomposition of the time-resolved spectra of (a) neat RR-P3HT film and (b) RR-P3HT/PCBM 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. D*, CT, and D+ represent PIAs due to singlet exciton, CT state, and carrier, respectively.
