Transparent conducting electrodes, methods for manufacturing such conducting electrodes, optoelectronic devices incorporating such transparent electrodes and methods for making such optoelectronic devices and solar power generation systems incorporating such electrodes are disclosed. Nanostructured transparent conducting electrodes may include a nano-architected porous film having a network of ordered interconnected pores and an electrically conductive material that substantially fills the pores. The nano-architected porous film may be disposed on a layer of transparent conducting material. The electrode may include a substrate (e.g., glass or polymer) and the layer of transparent conducting material may be disposed between the substrate and the nano-architected porous film. Nanostructured transparent conducting electrodes may be fabricated by forming a nano-architected porous film, e.g., by surfactant temptation, on a layer of transparent conducting material and substantially filling the pores in the nano-architected porous film with an electrically conductive material, e.g., by electrodeposition. Optoelectronic devices may incorporate one or more nanostructured transparent conducting electrodes in electrical contact with an active layer. Such devices may be made by fabricating a first electrode and disposing an active layer between the first electrode and a second electrode, one of which is a nanostructured transparent conducting electrode.
