Photovoltaic (PV) devices based on CdSe/CdTe‐C60 active layers, in which the nanocrystal and fullerene (C60) layers work as electron‐donor and electron‐acceptor/transport layers, respectively, were fabricated. Efficiencies up to 0.62% were reached in the hybrid cells. The PV performance was greatly improved with respect to that of CdSe/CdTe‐P3HT‐ and CdSe/CdTe‐based devices, fabricated as reference.
