A method for creating a nanostructure according to one embodiment includes depositing material in a template for forming an array of nanocables; removing only a portion of the template such that the template forms an insulating layer between the nanocables; and forming at least one layer over the nanocables. A nanostructure according to one embodiment includes a nanocable having a roughened outer surface and a solid core. A nanostructure according to one embodiment includes an array of nanocables each having a roughened outer surface and a solid core, the roughened outer surface including reflective cavities; and at least one layer formed over the roughened outer surfaces of the nanocables, the at least one layer creating a photovoltaically active p-n junction. Additional systems and methods are also presented.
