      Bulk heterojunction solar cells with   highly ordered one-dimensional (1D) nanostructured components of   semiconducting conjugated polymers, dyes, and metal oxides, are   reviewed in terms of device structure and performance. The   morphologically controlled semiconducting materials show   characteristic features of the light-harvesting and photocurrent   generation. We highlight the recent progress and improvement of   self-assembling 1D materials for a donor-acceptor active layer as   well as an electron-transporting layer in organic solar cells.   Strategies of the fabrication procedures and origin of the   photophysical properties are summarized. 1D nanostructured   semiconducting materials that are vertically phase-separated with   respect to a transparent conducting electrode facilitate   efficient carrier transportation and collection.
