A facile new protocol for the synthesis of iodinated derivatives of fluorinated benzothiadiazoles is demonstrated for the production of p‐type semiconducting materials. The newly synthesized small‐molecule compounds bis[TPA‐diTh]‐MonoF‐BT and bis[TPA‐diTh]‐DiF‐BT exhibited a power conversion efficiency of 2.95 % and a high open‐circuit voltage of 0.85 V in solution‐processed small‐molecule organic solar cells.
