Intrinsic traps in organic semiconductors can be eliminated by trap‐filling with F4‐TCNQ. Photovoltaic tests show that devices with F4‐TCNQ at parts per thousand concentration outperform control devices due to an improved fill factor. Further studies confirm the trap‐filling pathway and demonstrate the general nature of this finding.
