A package is produced having an external and highly visible tamper evidencing band which surrounds portions of both a container lip flange and the periphery of a closure lid. A distal portion of the band is mechanically formed using a forming tool to have an inwardly directed portion which cooperates with an inwardly directed band flange to securely hold the container and closure lid together. The band must be removed to successfully open the package.

An interconnected arrangement of photovoltaic cells is achieved using laminating current collector electrodes. The electrodes comprise a pattern of conductive material extending over a first surface of sheetlike substrate material. The first surface comprises material having adhesive affinity for a selected conductive surface. Application of the electrode to the selected conductive surface brings the first surface of the sheetlike substrate into adhesive contact with the conductive surface and simultaneously brings the conductive surface into firm contact with the conductive material extending over first surface of the sheetlike substrate. Use of the laminating current collector electrodes allows facile and continuous production of expansive area interconnected photovoltaic arrays.

Collector grid and interconnect structures for photovoltaic arrays and modules

A interconnected arrangement of photovoltaic cells is readily and efficiently achieved by using a unique interconnecting strap. The strap comprises electrically conductive fingers which contact the top light incident surface of a first cell and extend to an interconnect region of the strap. The interconnect region may include through holes which allow electrical communication between top and bottom surfaces of the interconnect region. In one embodiment, the electrically conductive surface of the fingers is in electrical communication with an electrically conductive surface formed on the opposite side of the strap through the through holes of the interconnect region. The interconnection strap may comprise a laminating film to facilitate manufacture and assembly of the interconnected arrangement.

An interconnected arrangement of photovoltaic cells is achieved using novel interconnection components. The interconnection component may comprise a current collector structure, an interconnection structure, or a combination of a current collector and interconnection structure.

The invention teaches novel structure and methods for producing electrical current collectors and electrical interconnection structure. Such articles find particular use in facile production of modular arrays of photovoltaic cells. The current collector and interconnecting structures may be initially produced separately from the photovoltaic cells thereby allowing the use of unique materials and manufacture. Subsequent combination of the structures with photovoltaic cells allows facile and efficient completion of modular arrays. Methods for combining the collector and interconnection structures with cells and final interconnecting into modular arrays are taught.

This invention comprises manufacture of photovoltaic cells by deposition of thin film photovoltaic junctions on metal foil substrates. The photovoltaic junctions may be heat treated if appropriate following deposition in a continuous fashion without deterioration of the metal support structure. In a separate operation, an interconnection substrate structure is provided, optionally in a continuous fashion. Multiple photovoltaic cells are then laminated to the interconnection substrate structure and conductive joining methods are employed to complete the array. In this way the interconnection substrate structure can be uniquely formulated from polymer-based materials employing optimal processing unique to polymeric materials. Furthermore, the photovoltaic junction and its metal foil support can be produced in bulk without the need to use the expensive and intricate material removal operations currently taught in the art to achieve series interconnections.
