  • Patent number: 8647910
    Abstract: The present invention relates to masking pastes and methods for removing portions of the back electrode and photovoltaic junction from a photovoltaic laminate to create a partially transparent thin-film photovoltaic panel. Such panels may be useful in window and sun-roof applications. This method can be used to edge-delete and electrically isolate a photovoltaic panel and to reduce the reflectivity of the sun-facing substrate surface.

  • Patent number: 8592248
    Abstract: The present invention relates to a chemical etching method to electrically isolate the edge from the interior of a thin-film photovoltaic panel comprising a substrate and a photovoltaic laminate. The method comprises a step to dispense an etching paste comprising two or more acids on the laminate periphery; an optional step to apply heat to the laminate; and a step to remove the etching paste. The method is further characterized by the chemical removal of at least two chemically distinctive layers of the laminate at the periphery where the etching paste is applied. The method may be used to produce a thin-film photovoltaic panel.
