Patent ID: 7145071

Claim:
A solar cell comprising: a first electrode having a first planar surface and comprising a first plurality of fingers extending from the first planar surface of the first electrode, wherein side walls of the first plurality of fingers are substantially perpendicular to the first planar surface; a second electrode having a second planar surface and comprising a second plurality of fingers extending from the second planar surface of the second electrode and in a direction toward the first planar surface of the first electrode without contacting the first planar surface, wherein side walls of the second plurality of fingers are substantially perpendicular to the second planar surface, the first and second plurality of fingers disposed alternatingly between one another and overlapping one another substantially in a single plane; and a dye-sensitized semiconductor material provided between the first electrode and the second electrode, wherein the dye-sensitized semiconductor material is provided about the first and second plurality of fingers.
