    摘要: A micro-extrusion printhead assembly utilized in a micro-extrusion system to form parallel extruded lines of material on a substrate includes a material feed system for pushing/drawing materials out of extrusion nozzles defined in the printhead assembly, a Z-axis positioning mechanism, and a base. The micro-extrusion printhead includes a layered nozzle structure sandwiched between back and front plate structures. The layered nozzle structure includes stacked plates including top and bottom nozzle plates sandwiching a nozzle outlet plate. According to various embodiments, at least one of the nozzle structure materials of the printhead assembly, the output geometry of the printhead assembly, and the internal conduit geometry of the printhead assembly are modified to cause the bead traveling through the extrusion nozzle to be reliably directed (biased) toward the target substrate as it leaves the printhead nozzle orifice.

    摘要: A micro-extrusion printhead assembly utilized in a micro-extrusion system to form parallel extruded lines of material on a substrate includes a material feed mechanism for pushing/drawing materials out of dispensing orifices defined in the printhead assembly, a Z-axis positioning mechanism, and a base. A production method utilizes the micro-extrusion system to directly print endpoint structures at the end of each gridline, and by extruding these gridlines immediately after forming the busbars. In accordance with an embodiment of the invention, the micro-extrusion system is controlled to manipulate the printhead speed and/or gridline material extrusion pressure at the beginning, middle and end of each gridline printing process such that teardrop-shaped endpoint structures are formed at the ends of each gridline, whereby each endpoint structure has a substantially greater width than that of the main “central” gridline structure extending between the endpoint structures.

    摘要: A solar cell includes two backside metallization materials that are simultaneously extrusion deposited on a semiconductor substrate such that both a back surface field (BSF) metal layer (e.g., Al) and a solder pad metal structure (e.g., AgAl) are coplanar and non-overlapping, and the two metals abut each other to form a continuous metal layer that extends over the backside surface of the substrate. In one embodiment, the solder pad metal is formed directly on the backside surface of the substrate, either by co-extruding the two materials in the form of a continuous sheet, or by depositing spaced apart structures that are then flattened to contact each other by way of an air jet device. In another embodiment, the solder pad metal is disposed over a thin layer of the BSF metal (i.e., either disposed directly on the BSF metal, or disposed on an intervening barrier layer) using a co-extrusion head.
