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.
