We have compared the performance of Thin/NR cells to conventional hybrid cells in which the same NRAs are completely filled with organic blend (Thick/NR). The Thin/NR design absorbs at least as much light as Thick/NR cells, while charge extraction is significantly enhanced due to the proximity of the electrodes, resulting in a higher current density per unit volume of blend and improved power conversion efficiency. The NRAs need not be periodic or aligned and hence can be made very simply.enAttribution 2.0 Generichttps://creativecommons.org/licenses/by/2.0/PhotovoltaicElectrodepositionP3HT-PCBMBulk heterojunctionNanostructuredZnO nanorod arraysHybrid solar cellsArticle
