Carrier Formation Dynamics in Prototypical Organic Solar Cells as Investigated by Transient Absorption Spectroscopy

Figure 9

ΔOD spectra of (a) rr-P3HT/PCBM blend, (b) PCBM neat, and (c) rr-P3HT neat films at 300 K. Top panels show optical density (OD) of the films at 300 K. Downward arrows represent the wavelength of the pump pulse. The data were replotted from [46].
