Order of dipole moment layers at donor and acceptor interfaces in bilayer organic solar cells is manipulated reversibly by applying bias voltages. The energy level shifts at the interfaces induce reversible changes in the open circuit voltage and the diode properties. This finding could lead to a better understanding of the structure–property relationship at the materials interfaces in organic optoelectronic devices.
