摘要: Closely spaced, high aspect-ratio gridline structures are formed on the surface of a substrate using two or more co-extrusion heads that co-extrude material and sacrificial such deposited is compressed between opposing portions material. The include three-channel cavity converge to relatively small outlet orifice dispenses with fine features aspect ratio. orifices disposed in staggered arrangement gridlines extruded from first head second head. Photovoltaic cells produced metal this manner.
