Abstract: An inorganic/organic hybrid nanolaminate barrier film has a plurality of layers of an inorganic material that alternate with a plurality of layers of an organic material. Such a barrier film can be fabricated using nanocomposite self-assembly techniques based on sol-gel chemistry.

Abstract: Nano-architected/assembled solar cells and methods for their manufacture are disclosed. The solar cells comprise oriented arrays of nanostructures wherein two or more different materials are regularly arrayed and wherein the presence of two different materials alternates. The two or more materials have different electron affinities. The two materials may be in the form of matrixed arrays of nanostructures. The presence of the two different materials may alternate within distances of between about 1 nm and about 100 nm. An orientation can be imposed on the array, e.g. through solution deposition surfactant templation or other methods.

Abstract: Transparent conductive electrodes, optoelectronic apparatus, optoelectronic devices and methods for making such electrodes, apparatus and devices are disclosed. The transparent conducting electrode (TCE) includes a layer of transparent electrically conducting polymer material and an array of electrically conductive wires distributed across the layer of transparent electrically conducting polymer material. The TCE may be made by distributing an array of conductive wires across a conductive polymer layer and attaching polymer layer to the wire array. An optoelectronic apparatus may comprise an active layer in electrical contact with the TCE. An optoelectronic device may incorporate an active layer disposed between two electrodes, at least one of which is the TCE. An optoelectronic device may be made by disposing an active layer between a base electrode and a TCE and attaching all three together.

Abstract: Charge-splitting networks, optoelectronic devices, methods for making optoelectronic devices, power generation systems utilizing such devices and method for making charge-splitting networks are disclosed. An optoelectronic device may include a porous nano-architected (e.g., surfactant-templated) film having interconnected pores that are accessible from both the underlying and overlying layers. A pore-filling material substantially fills the pores. The interconnected pores have diameters of about 1-100 nm and are distributed in a substantially uniform fashion with neighboring pores separated by a distance of about 1-100 nm. The nano-architected porous film and the pore-filling, material have complementary charge-transfer properties with respect to each other, i.e., one is an electron-acceptor and the other is a hole-acceptor. The nano-architected porous, film may be formed on a substrate by a surfactant temptation technique such as evaporation-induced self-assembly.
