NOVELTY - A solar cell (10) comprises: (i) a first planar electrode comprising a transparent material; (ii) a second electrode proximately positioned at a distance from the first electrode, and comprising a metal foil portion extending in a direction that is different from the direction of the surface of the first planar electrode; and (iii) a porous dye sensitized semiconductor material electrically coupled to the second electrode.    USE - Used to produce electricity from sunlight.    ADVANTAGE - The assembly has increased efficiency, since recombination losses and diffusion losses in the electrolyte are reduced. The cost/watt delivered is reduced. The inventive metal foil is resistant to iodine corrosion, such that the structural integrity of the first electrode is not degraded by the electrolyte solution in the solar cell. No sintering process is needed, thus reducing the solar cell fabrication steps. The ion transport in and out of the cavities may be much quicker than through the torturous paths that may exist, due to the typical random arrangement of crystallites in the layer of nano-crystalline titanium oxide. The surface chemistry may be well controlled and better defined using electrochemical oxidation rather than chemical vapor deposition, to provide the semiconductor material. The invention achieves a more precise control of the optical path length by controlling the thickness of titanium foil used to form the first electrode. The thickness of the layer of titanium oxide can be controlled to allow maximum cell potential and short circuit current to be achieved.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of forming a solar cell, comprising:    (a) placing a conductive layer on a substrate (14);    (b) forming nanowires, which are electrically coupled to and extend from the conductive layer;    (c) forming a semiconductive layer on each of the nanowires and on the conductive layer;    (d) covering the semiconductive layer with a dye to form a dye-sensitized semiconductive layer; and    (e) placing an electrolyte (20) solution on the dye-sensitized semiconductive layer.    DESCRIPTION OF DRAWING(S) - The figure illustrates a cross-sectional view of a dye-sensitized solar cell.    Solar cell (10)    Titanium dioxide (12)    Substrate (14)    Electrolyte (20)
