(a) The evolution of photocurrent generation from 0.86 V to 1 V. At Voc the charge generation through Step 1 and 2 (of Figure 1d) is shown to interact with TTA linked recombination that is expected to progress via step 3, 4, 7. (b) Comparison of EQE spectra at short-circuit (0 V) and +1 V. The spectrum presented for +1 V is sign corrected for convenience of comparison. The dominant nature of TTA and direct injection into T1 moves free charge generation entirely to the rubrene layer.
