摘要： Abstract A photosensitive optoelectronic device having an improved hybrid planar bulk heterojunction includes a plurality of photoconductive materials (950) disposed between the anode (120) and the cathode (170). The photoconductive materials (950) include a first continuous layer of donor material (152) and a second continuous layer of acceptor material (154). A first network of donor material or materials (953c) extends from the first continuous layer (152) toward the second continuous layer (154), providing continuous pathways for conduction of holes to the first continuous layer (152). A second network of acceptor material or materials (953b) extends from the second continuous layer (154) toward the first continuous layer (152), providing continuous pathways for conduction of electrons to the second continuous layer (154). The first network (953c) and the second network (953b) are interlaced with each other. At least one other photoconductive material (953a, 953d) is interspersed between the interlaced networks. This other photoconductive material or materials (953a, 953d) has an absorption spectra different from the donor and acceptor materials.

摘要： An optoelectronic device and a method of fabricating a photosensitive optoelectronic device includes depositing a first organic semiconductor material on a first electrode to form a continuous first layer; depositing a layer of a second organic semiconductor material on the first layer to form a discontinuous second layer, portions of the first layer remaining exposed; and depositing the first organic semiconductor material on the second layer to form a discontinuous third layer, portions of at least the second layer remaining exposed. The depositing of the first and second organic semiconductor materials are alternated a number of times until a final layer of the second organic material is added to form a continuous layer. A second electrode is deposited over this final layer. One of the first electrode and the second electrode is transparent, and the first organic semiconductor material is one or more donor-type materials or one or more acceptor-type materials relative to second organic semiconductor material, which is one or more materials of the other material type.
