A photosensitive device includes a plurality of organic photoconductive m aterials disposed in a stack between a first electrode and a second electrod e, including a first continuous layer of donor host material, a second conti nuous layer of acceptor host material, and at least one other organic photoc onductive material disposed as a plurality of discontinuous islands between the first continuous layer and the second continuous layer. Each of these ot her photoconductive materials has an absorption spectra different from the d onor host material and the acceptor host material. Preferably, each of the d iscontinuous islands consists essentially of a crystallite of the respective organic photoconductive material, and more preferably, the crystallites are nanocrystals.
