A p–n junction in an organic emissive polymer is chemically fixed through the use of polymerizable ions. This leads to a permanent configuration of compensating ions, unlike dynamic light‐emitting electrochemical cells. The process is demonstrated with red‐, green‐, and blue‐light‐emissive polymers; a photovoltaic effect is also demonstrated.
