Method for integrated series connection of thin film solar cells

摘要

The present invention relates to a method for providing integrated series connections of a plurality of solar cells each of which includes a photovoltaic thin film on a common transparent substrate which involves depositing a strip pattern of a material which is readily removable from the photovoltaic thin film onto the film at intervals dependent on the size of the solar cells, the strips of the pattern being offset laterally relative to the front electrodes lying under the thin film and extending over the regions of the thin film which are not to be covered by the subsequently back electrodes. Separating grooves are then mechanically generated in the film adjacent the strips. An electrically conductive metal is deposited over the entire surface thus produced and finally the strip pattern is removed by lifting the pattern off the film, leaving gaps in the metallized layer forming the separated back electrodes of the solar cell.
