    摘要： Laser based processes are used alone or in combination to effectively process doped domains for semiconductors and/or current harvesting structures. For example, dopants can be driven into a silicon/germanium semiconductor layer from a bare silicon/germanium surface using a laser beam. Deep contacts have been found to be effective for producing efficient solar cells. Dielectric layers can be effectively patterned to provide for selected contact between the current collectors and the doped domains along the semiconductor surface. Rapid processing approaches are suitable for efficient production processes.

    摘要： Layered metal structures are patterned to form a surface with some locations having an alloy along the top surface at some locations and the original top metal layer at other locations along the surface. The alloy and original top metal layer can be selected to have differential etching properties such that the pattern of the alloy or original metal can be selectively etched to form a patterned metal interconnect. In general, the patterning is performed by localized heating that drives formation of the alloy at the heated locations. The metal patterning can be useful for solar cell applications as well as for electronics applications, such as display applications.

    摘要： Photovoltaic elements can be formed by in-motion processing of a silicon ribbon. In some embodiments, only a single surface of a silicon ribbon is processed in-motion. In other embodiments both surfaces of a silicon ribbon is processed in-motion. In-motion processing can include, but is not limited to, formation of patterned or uniform doped regions within or along the silicon ribbon as well as the formation of patterned or uniform dielectric layers and/or electrically conductive elements on the silicon ribbon. After performing in-motion processing, additional processing steps can be performed after the ribbon is cut into portions. Furthermore, post-cut processing can include, but is not limited to, the formation of solar cells, photovoltaic modules, and solar panels.
