In double‐junction organic solar cells , the optical absorption of the back sub‐cell is enhanced by coupling between the microcavity and surface plasmon polariton modes at the Ag/back sub‐cell interface through the introduction of a periodic wavelength‐scale corrugation into the device structure. The improved optical absorption of the back sub‐cell leads to a balanced photocurrent of front and back sub‐cells.
