Figure 5

Nongeminate recombination dynamics and charge carrier mobility.

Extracted charge carrier density n vs. td derived from OTRACE measurements under 1 sun illumination intensity on PBDTTT-C:PC71BM devices with varying DIO content. The arrows indicate the trend of the inverse slope λ derived from a power law fit n(t) ~ t−1/λ in the fast and slow recombination regime (shaded). The inset shows the charge carrier mobility μ vs. DIO content obtained from OTRACE transients. The shaded area indicates the standard deviation.
