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.

Abstract: Provided are photovoltaic module assemblies configured for improved installation. The assemblies include frameless photovoltaic modules and retainers for supporting the modules on mounting structures. The retainers support the modules at least during cure of adhesive materials provided between the modules and the mounting structures. Once cured, the adhesive materials provide permanent support to the modules. The retainers may interlock with the mounting structures during installation or be integral components of the structures. In certain embodiments, retainers are used to control a gap between the modules and mounting structures. Retainers may be removable and collected after installation is completed. Alternatively, retainers may remain as parts of assemblies at least during some initial period. Retainers may be made from various degradable materials, such as biodegradable plastics, UV degradable plastics, and/or water soluble materials.

Abstract: Provided are novel building integrable photovoltaic (BIP) modules and methods of installing thereof. A module may include a photovoltaic insert having at least one photovoltaic cell, a channel provided on one edge of the insert, and an extension provided on the opposite edge. The extension is configured to fit snugly into a corresponding channel of an adjacent module during installation. The two modules may have the same design and form a photovoltaic array, which may involve interconnecting with additional modules. The interconnection prevents lifting of one module with respect another. Therefore, each module needs to be attached to a building structure only along one edge, while the opposite edge is supported by another module. Attachment to the building structure may be in a concealed area of the module, such as a moisture flap, to prevent exposed though holes. This configuration improves moisture sealing properties of the resulting array.
