Embodiment Construction

[0037] The present invention provides methods and apparatus for interconnecting flexible thin film photovoltaic (PV) cells in a scalable and efficient process. Specifically, examples of the present invention relate to the roll-to-roll combination of flexible photovoltaic cells on a flexible current-carrying backsheet. The back film can be a conductive substrate on which a plurality of photoactive materials are arranged.

[0038] According to the present invention, methods and systems for interconnecting thin-film photovoltaic cells in a flexible substrate package may include a string of a plurality of photovoltaic cells and a transparent film covering the photovoltaic cells. on film. Electrically conductive paths are established by connecting an upper or "sun-facing" side of one photovoltaic cell to the upper surface of the conductive substrate underlying the photoactive material of an adjacent photovoltaic cell. Portions of the photoactive material of the interconnected pho...

Description

[0001] Cross-reference to related applications [0002] This application claims priority from US Provisional Application No. 61 / 625,553, filed April 17, 2012, which is incorporated by reference in its entirety. This application also incorporates by reference the following patents and applications in their entirety: US Patent No. 8,062,922, US Patent No. 7,194,197, US Patent No. 6,690,041, US Patent No. 6,372,538, US Patent No. 6,310,281, and US Patent Application Publication No. 2012 / 0000502. technical field [0003] The present application relates to the interconnection of monolithic thin-film solar cells. Background technique [0004] The field of photovoltaic materials is generally concerned with multilayer materials that can directly convert sunlight into DC electricity. The basic mechanism for this conversion is the photovoltaic effect, first discovered by Antoine-César Becquerel in 1839 and correctly explained by Einstein in a 1905 Symposium Scientific paper for whic...
