Abstract:
A method of manufacturing improved thin-film solar cells entirely by sputtering includes a high efficiency back contact/reflecting multi-layer containing at least one barrier layer consisting of a transition metal nitride. A copper indium gallium diselenide (Cu(InXGa1-X)Se2) absorber layer (X ranging from 1 to approximately 0.7) is co-sputtered from specially prepared electrically conductive targets using dual cylindrical rotary magnetron technology. The band gap of the absorber layer can be graded by varying the gallium content, and by replacing the gallium partially or totally with aluminum. Alternately the absorber layer is reactively sputtered from metal alloy targets in the presence of hydrogen selenide gas. RF sputtering is used to deposit a non-cadmium containing window layer of ZnS. The top transparent electrode is reactively sputtered aluminum doped ZnO. A unique modular vacuum roll-to-roll sputtering machine is described. The machine is adapted to incorporate dual cylindrical rotary magnetron technology to manufacture the improved solar cell material in a single pass.

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.

Abstract:
Provided are novel building integrable photovoltaic (BIPV) modules having integrated jumpers for interconnecting similar modules in adjacent rows. An integrated jumper is provided on a back side of the photovoltaic portion of the module and includes at least two interconnected jumper contact points. The module also has two connectors provided on the front side of its flap portion. Each connector has at least one connector contact point connected to one or more photovoltaic cells of the module. When a module is positioned over flap portions of two other modules previously installed in an adjacent row, the two jumper contact points on the back side of this new module make electrical connections to the two connector contact points on the front side of the installed modules. In turn, these connections interconnect the photovoltaic cells of the two modules without any need for additional connectors or operations.
Abstract:
Provided are novel building integrable interconnection structures having field-configurable shapes and methods of installing thereof. An interconnection structure may be cut or otherwise modified in the field during installation to form one or more openings. These openings can then be positioned around various obstacles that are frequently present in building installation areas. Some examples of such obstacles include chimneys, vents, and skylights. In some embodiments, the interconnection structures can be provided as part of a set or configured to be installed in an array with building integrable photovoltaic (BIPV) modules of the same size. This installation configuration allows preserving an offset between adjacent rows of the array. Furthermore, the interconnection structures can have the same perimeter features as the BIPV modules, such as electrical connectors and moisture flaps. These features provide electrical continuity and sealing characteristics in an array of BIPV modules despite the presence of obstacles on building structures.
