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

摘要： Methods are disclosed for fabricating spring structures that minimize helical twisting by reducing or eliminating stress anisotropy in the thin films from which the springs are formed through manipulation of the fabrication process parameters and/or spring material compositions. In one embodiment, isotropic internal stress is achieved by manipulating the fabrication parameters (i.e., temperature, pressure, and electrical bias) during spring material film formation to generate the tensile or compressive stress at the saturation point of the spring material. Methods are also disclosed for tuning the saturation point through the use of high temperature or the incorporation of softening metals. In other embodiments, isotropic internal stress is generated through randomized deposition (e.g., pressure homogenization) or directed deposition techniques (e.g., biased sputtering, pulse sputtering, or long throw sputtering). Cluster tools are used to separate the deposition of release and spring materials.

摘要： A binary diffractive optical element is used as a single element beam homogenizer. The phase profile of the binary surface relief phase grating structure of the binary diffractive optical element will reprofile diffractively a spatially non-uniform intensity profile of a light beam into multiple overlapping beams which recombine to form a light beam with a more uniform intensity profile.

摘要： A laser beam conditioner consists of a partially reflective surface having a uniform reflectivity of approximately 38.2 percent and a totally reflective surface on opposite sides of a substrate. A coherent light beam incident onto the partially reflective surface of the laser beam conditioner will be partially reflected and partially transmitted. The partially transmitted portion of the coherent light beam will be multiply reflected between the totally reflective mirror and the partially reflective mirror within the beam conditioner, with a portion of light transmitted through the partially reflective mirror at each multiple reflection. The initially reflected portion of the coherent light beam and the transmitted portions of the multiply reflected beams form a conditioned light beam for a homogenizer. The partially reflective surface and the totally reflective surface are slightly less than parallel in order to introduce a minute angular spread among the delayed components of the multiply reflected beam. The spacing between the partially and totally reflective surfaces is at least half the coherence length of the laser beam.

摘要： A monolithic multi-wavelength laser diode array having a composite active region of at least two dissimilar quantum well layers that are partially mixed in at least one of their constituent atomic species in at least one area of the active region. Different areas of the active region are characterized by different emission wavelengths determined by the degree of intermixing. An impurity free interdiffusion, such as vacancy enhanced interdiffusion, is used to provide the intermixing. Each area may have one or more waveguides and distributed Bragg reflector gratings tuned to the emission wavelength of the corresponding area of the active region. Each area or waveguide may also be separately pumped with an individually addressable current injection electrode. The laser output may be coupled into a ferroelectric frequency doubler integrally formed on the array substrate. The frequency doubler has periodically poled waveguides for quasi-phase matching in front of areas of the laser array emitting light which is to be doubled in frequency.

摘要： Solar cells include bus bars and high aspect-ratio gridlines that are printed on a substrate, and localized melting is induced to slump or flatten the gridline “vertex” portions that are disposed on the bus bars, while maintaining the high aspect-ratio of gridlines portions disposed on the substrate between the bus bars. The localized melting process is induced using one of several disclosed methods, such as rheological melting in which the two printed inks produce a compound that is relatively liquid. Localized melting is also induced using a deliquescing material (e.g., a flux or a solvent film) that is applied to the bus bar or gridline material. Also, eutectic melting is induced using a processing temperature that is between a melting point of the combined gridline/bus bar inks and the individual melting points of the inks alone. Laser-based melting and the use of copolymers is also disclosed.
