(a) Relative differential transmission (ΔT/T) of P3HT:PCBM ranged from 520 nm to 1,200 nm. Selected times are 1 ps, 10 ps, 100 ps, 1 ns and 2 ns after excitation with 500-nm laser beam. A comparison of the fs-TAS signals of Ag-P3HT:PCBM and P3HT:PCBM BHJ films at (b) 1 ps and (c) 1 ns after photoexcitation.
