    摘要： Wafer-based solar cells are efficiently produced by extruding a dopant bearing material (dopant ink) onto one or more predetermined surface areas of a semiconductor wafer, and then thermally treating the wafer to cause diffusion of dopant from the dopant ink into the wafer to form corresponding doped regions. A multi-plenum extrusion head is used to simultaneously extrude interdigitated dopant ink structures having two different dopant types (e.g., n-type dopant ink and p-type dopant ink) in a self-registered arrangement on the wafer surface. The extrusion head is fabricated by laminating multiple sheets of micro-machined silicon that define one or more ink flow passages. A non-doping or lightly doped ink is co-extruded with heavy doped ink to serve as a spacer or barrier, and optionally forms a cap that entirely covers the heavy doped ink. A hybrid thermal treatment utilizes a gaseous dopant to simultaneously dope exposed portions of the wafer.

    摘要： A printing plate has a substrate, an array of cells on the substrate, wherein each cell corresponds to an element of a print image, a deformable polymer material localized into the cells such that each cell is at least partially formed from the deformable polymer material, a reservoir corresponding to each cell to collect the deformable polymer material as needed when the deformable polymer material is one of either melted or softened, and a heater to cause the deformable polymer material to either melt or soften. A method of forming a printing plate provides an array of cells, first heats the array of cells such that the deformable polymer material does one of either melts or softens, actuates the cells in the array to assume a deformed state, cools the array of cells to solidify the cells in the deformed state, second heats the cells such that the deformable polymer material in selected ones of the cells does one of either soften or melt and return to a less deformed state to form a printing pattern, and cools the surface to solidify the deformable polymer material in the printing pattern. A method of forming a printing plate provides an array of cells, heats the array of cells such that the deformable polymer material softens, actuates selected ones of the cells to deform surfaces of the selected ones to form a printing pattern, and cools the array of cells to solidify the printing pattern into a printing plate.

    摘要： A micro-extrusion printhead assembly utilized in a micro-extrusion system to form parallel extruded gridlines of material on a substrate includes a nozzle having a tapered (e.g., triangular or trapezoidal) cross-section arranged such that a lower surface of each gridline is substantially wider than its upper edge, and such that side surfaces of the extruded gridlines reflect incident light beams into exposed surface areas of the substrate, thereby minimizing the effective shadowed surface area under the gridline. In one embodiment, the fluidic channels of each nozzle are fabricated by cutting or etching progressively wider channels into a series of rigid layers, and then stacking the rigid layers to form a layered nozzle structure. In another embodiment, a single layer is processed to include a tapered cross-section having the desired triangular or trapezoidal cross-section.

    摘要： A co-extrusion device has at least one first inlet port to receive a first material, at least one second inlet port to receive a second material, a first combining channel arranged to receive the first material and the second material and combine the first and second materials into a first combined flow flowing in a first direction. a splitter channel arranged to receive the first combined flow and to split the first combined flow into at least two split flows in a second direction at least partially orthogonal to the first direction, wherein each split flow consists of the first and second materials, and a second combining channel arranged to receive the split flows and combine the split flows into a second combined flow in the first direction, and at least one exit orifice arranged to allow the materials to exit the device as a single flow. A method for depositing a structure comprising interdigitated materials includes merging flows of at least two materials in a first direction into a first combined flow, dividing the first combined flow in a second direction to produce at least two separate flows, wherein the second direction is perpendicular to the first direction, and merging the two separate flows into a second combined flow.
