The realization of polymer solar cells is the driving force behind this research. In an idea inspired by photosynthesis, the authors have constructed efficient bilayer photodiodes by a well‐chosen combination of conjugated polymers (see Figure) in the donor layer. Förster energy transfer within the donor layer allows the absorbed light to be channeled to the C 60 acceptor layer, improving the total photoconversion of the blend device.
