Claims18
A photovoltaic cell comprising:
- an array of microelectrodes on a substrate, said microelectrodes comprised of a conductive or semi-conductive material, each of said microelectrodes shaped as a uniformly spaced apart protrusion, wherein the microelectrodes comprise both anodes and cathodes, wherein the conductive or semi-conductive material is selected from:
- carbon, a carbon allotrope, or an organic polymer, or combinations thereof;
- wherein each of said uniformly spaced apart protrusion has a diameter of at least 150 μm and a height that is greater than the diameter;
- wherein the uniform spacing between protrusions is from about 0.5 μm to about 350 μm, and wherein the anodes are coated with a conductive polymer;
- and,
- at least one photoactive material in combination with said microelectrodes, wherein the photoactive material comprises crystalline silicone, cadmium telluride copper-indium selenide, copper indium/gallium diselenide, ruthenium metalorganic dye, P3HT (poly(3-hexylthiophene)), PCBM (phenyl-C61-butyric acid methyl ester), or combinations thereof;
- and,
- one or more wire traces layered on or within the substrate connecting two or more microelectrodes.
