A nanocomposite of highly conductive C 60 and insulating LiF (C 60 :LiF) is shown to function as both a highly effective passivation layer and hole blocking layer in polymer bulk heterojunction solar cells. C 60 :LiF composites with up to ≈80% LiF concentration dramatically increase the device stability and power conversion efficiency, enabling a new generation of high‐performance and long lifetime organic photovoltaics on flexible substrates.
