ABSTRACT:
A solar cell having foil electrodes. Specifically, a metal foil is implemented to form electrodes providing a reduced electron path from a dye-sensitized semiconductor material to the electrodes. In one embodiment, nanowires extending from the substrate on which the solar cell is formed are provided. In another embodiment, cavities are formed in a sheet of conductive foil by oxidation, thereby forming a semiconductive material. The semiconductive material is sensitized with a dye and an electrolyte solution is disposed in the cavities, thereby forming an array of dye-sensitized solar cells.
