The conversion efficiencies of organic photovoltaic devices have been improved by a factor of 4–5 by introducing a large surface‐area interface between the donor and acceptor layers. Stratified films of a fullerene‐based acceptor (see Figure) were spin‐coated on top of a donor (MDMO‐PPV), forming a diffuse interface with unusual morphology that displayed high energy‐conversion efficiencies.
