  • Publication number: 20190181294
    Abstract: Provided are novel interconnect wire network assemblies and methods of fabricating thereof. An assembly may include conductive portions/individual wires that, in certain embodiments, are substantially parallel to each other. The assembly also includes two or more carrier films (i.e., the front side and back side films) attached to opposite sides of the wires. The films are typically attached along the wire ends. The films are made from electrically insulating materials and at least the front side film is substantially transparent. The front side film is used to attach the wires to a photovoltaic surface of one cell, while the back side film is used for attachment to a substrate surface of another cell. These attachments electrically interconnect the two cells in series. In certain embodiments, one or both carrier films extend beyond two end wires and form insulated portions that allow much closer arrangements of the cells in a module.

  • Patent number: 9895630
    Abstract: Systems and methods are provided for accurately measuring and allocating treated oil. Separators can be modified to include automatic control systems utilizing active flow controls and level sensors. The automatic control systems can be configured to cause oil to flow at a rate and with a duration sufficient to accurately measure the amount of oil transferred from the separator. The systems and methods also provide for a method of correcting for oil density variations. The systems and methods also allow for fail-safe operations by having the active flow controls fail in an open position allowing pre-existing passive flow control valves to operate normally.

  • Publication number: 20160133769
    Abstract: Provided are bypass diode assemblies for use in photovoltaic modules. Also provided are methods of fabricating such assemblies and a method of fabricating photovoltaic modules using such assemblies. A diode assembly may include an insulating strip, at least one lead-diode assembly having a diode and two leads, and at least two interconnecting conductors overlapping with and electrically contacting the leads of the lead-diode assembly. The insulating strip supports the lead-diode assembly and conductors and at least partially insulates these components from photovoltaic cells. Specifically, during module fabrication, the interconnecting conductors make electrical connections to the back sides of the cells through cutouts in the insulating strip. The electrical connections may be made to every cell in a row or a subset of selected cells in that row. In certain embodiments, the same interconnecting conductor is connected to two or more cells positioned in adjacent rows.

  • Patent number: 8586398
    Abstract: Provided herein are methods of incorporating additives into thin-film solar cell substrates and back contacts. In certain embodiments, sodium is incorporated into a substrate or a back contact of a thin-film photovoltaic stack where it can diffuse into a CIGS or other absorber layer to improve efficiency and/or growth of the layer. The methods involve laser treating the substrate or back contact in the presence of a sodium (or sodium-containing) solid or vapor to thereby incorporate sodium into the surface of the substrate or back contact. In certain embodiments, the surface is simultaneously smoothed.

  • Patent number: 8546172
    Abstract: Provided herein are methods of polishing, cleaning and texturing back contacts of thin-film solar cells. According to various embodiments, the methods involve irradiating sites on the back contact with laser beams to remove contaminants and/or smooth the surface of the back contact. The back contact, e.g., a molybdenum, copper, or niobium thin-film, is smoothed prior to deposition of the absorber and other thin-films of the photovoltaic stack. In certain embodiments, laser polishing of the back contact is used to enhance the diffusion barrier characteristics of the back contact layer, with all or a surface layer of the back contact becoming essentially amorphous. In certain embodiments, the adhesion of the absorber layer is enhanced by the textured back contact and by the presence of the amorphous metal at the deposition surface.

  • Patent number: 8536054
    Abstract: Provided herein are methods of polishing and texturing surfaces thin-film photovoltaic cell substrates. The methods involve laser irradiation of a surface having a high frequency roughness in an area of 5-200 microns to form a shallow and rapidly expanding melt pool, followed by rapid cooling of the material surface. The minimization of surface tension causes the surface to re-solidify in a locally smooth surface. the high frequency roughness drops over the surface with a lower frequency bump or texture pattern remaining from the re-solidification.
