Abstract:
1. A photovoltaic device, comprising: a first electrode layer; a second electrode layer; and at least a first photoactive layer comprising a first sublayer and a second sublayer disposed between the first and second electrode layers, wherein the first sublayer comprises an electron-conducting first population of nanostructures which is made from a first material and the second sublayer comprises a hole-conducting second population of nanostructures that is made from a second material which is different from the first material, wherein the first and second populations of nanostructures are disposed in a nonconductive polymer matrix, and wherein the first and second populations of nanostructures are randomly oriented in the photoactive layer, and wherein at least a subset of nanostructures from at least the first population of nanostructures are at least partially fused to each other.
