摘要： There is disclosed ultrathin film material templating layers that force the morphology of subsequently grown electrically active thin films have been found to increase the performance of small molecule organic photovoltaic (OPV) cells. There is disclosed electron-transporting material, such as hexaazatriphenylene- hexacarbonitrile (HAT-CN) can be used as a templating material that forces donor materials, such as copper phthalocyanine (CuPc) to assume a vertical-standing morphology when deposited onto its surface on an electrode, such as an indium tin oxide (ITO) electrode. It has been shown that for a device with HAT-CN as the templating buffer layer, the fill factor and short circuit current of CuPc:C60 OPVs were both improved compared with cells lacking the HAT-CN template. This is explained by the reduction of the series resistance due to the improved crystallinity of CuPc grown onto the ITO surface.

摘要： The present disclosure relates to photosensitive optoelectronic devices comprising a compound blocking layer located between an acceptor material and a cathode, the compound blocking layer comprising: at least one electron conducting material, and at least one wide gap electron conducting exciton blocking layer. For example, 3,4,9,10 perylenetetracarboxylic bisbenzimidazole (PTCBI) and 1,4,5,8-napthalene-tetracarboxylic dianhydride (NTCDA) function as electron conducting and exciton blocking layers when interposed between the acceptor layer and cathode. Both materials serve as efficient electron conductors, leading to a fill factor as high as 0.70. By using an NTCDA/PTCBI compound blocking layer structure increased power conversion efficiency is achieved, compared to an analogous device using a conventional blocking layers shown to conduct electrons via damage-induced midgap states.

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.
