An organic electrochemical transistor operates in accumulation mode with high transconductance. The channel comprises a thiophene‐based conjugated polyelectrolyte, which is p‐type doped by anions injected from a liquid electrolyte upon the application of a gate voltage. The use of ethylene glycol as a co‐solvent dramatically improves the transconductance and the temporal response of the transistors.
