title: Photovoltaic efficiency enhancement by the generation of an embedded silica-like passivation layer along the P3HT/PCBM interface using an asymmetric block-copolymer additive.
abstract: A new approach to improve the power conversion efficiency of polymer bulk-heterojunction solar cells is demonstrated by generating a silica-like passivation layer embedded along the three-dimensionally intertwined interfaces between the nanoscopic domains of P3HT and PCBM by addition of an aymmetric block copolymer containing a short organo-silica precursor.
