Precise manipulation of organic donor‐acceptor interfaces using spacer layers is demonstrated to suppress interface recombination in an organic photovoltaic device. These strategies lead to a dramatic improvement in a model bilayer system and bulk‐heterojunction system. These interface strategies are applicable to a wide variety of donor–acceptor systems, making them both fundamentally interesting and technologically relevant for achieving high efficiency organic electronic devices.
