Abstract
A solar cell comprising at least one electrode having a plurality of fingers. Specifically, an electrode comprising a planar surface and a plurality of fingers extending therefrom is provided. A second electrode is provided. The second electrode comprises a planar surface and may comprise a plurality of fingers which are interdigitated with the fingers of the first electrode. The second electrode provides a catalyst material for the electron transfer to an oxidant during the photovoltaic process. A semiconductor material is disposed between the electrodes. The semiconductor material is saturated with dye and injected with an electrolyte solution. The fingers are arranged to provide a reduced migration path for the oxidant through the electrolyte and for the electrons through the semiconductor material when exposed to incident light.
