| What | The calculation of the Voc can be used to determine whether a new mechanism is involved or not. |
| Why | Engmann et al. experimentally and theoretically examined the higher-order effects in rubrene/C60 organic light-emitting diodes (OLEDs), claiming that triplet-triplet annihilation is not responsible for the electroluminescence with extremely-low turn-on voltage. |
| How | Direct singlet formation on rubrene and direct band-to-band recombination seems impossible to be accountable for such low Voc. |
