Adding increasing quantities of an n‐type compensating dopant, cobaltocene, to poly(3‐hexylthiophene) reveals an almost perfect mirror symmetry between the conductivity and the luminescence intensity. The sharp minimum/maximum shows that the uncompensated p‐type doping density is 1.2 × 1018 cm−3 and that excitons are strongly quenched by free charge carriers, not by bound charges.
Some mechanisms of charge transport in organic semiconductors and organic photovoltaic (OPV) cells can be distinguished by their predicted change in activation energy for the current, Ea, versus applied field, F. Ea versus F is measured first in pure films of commercially available regioregular poly(3‐hexylthiophene) (P3HT) and in the same P3HT treated to reduce its charged defect density. The former...
