Abstract

A solar cell structure formed by extruding/dispensing materials on a substrate such that centrally disposed conductive high aspect ratio line structures (gridlines) are formed on the substrate surface with localized support structures coincidentally disposed on opposing side surfaces of the gridlines such that the gridlines are surrounded or otherwise supported by the localized support structures. In one embodiment the localized support structures are transparent, remain on the substrate after the co-extrusion process, and are covered by a layer of material. In another embodiment, the localized support structures are sacrificial support structures that are removed as part of the solar cell structure manufacturing process. In both cases the co-extrusion process is performed such that both the central gridline and the localized support structures are in direct contact with the surface of the substrate.
