Figure 2. iPC results: the photocurrent measured as a function of the incident laser power varied by orders of magnitude in PTB7:PC70BM blends and PCDTBT:PC70BM blends with junction thickness of ∼ 230 nm.

Figure 2

The 1 sun equivalent laser power is marked by the dashed lines. The bimolecular recombination losses appear at the highest laser powers when the photocurrent becomes non-linear.
