Abstract
A bus grid structure is affixed to a photovoltaic device utilizing a double-sided adhesive tape in which one of the adhesive layers is electrically conductive and the other is electrically resistive. The tape is affixed to a photovoltaic device via the electrically resistive adhesive. Grid wires are applied to a top electrode of the photovoltaic device, and portions of those grid wires are adhered to the electrically conductive adhesive. A bus bar is also adhered to the electrically conductive adhesive so as to contact the portions of the grid wire. The assembly is laminated so as to bond the grid wires to the photovoltaic device and to the bus bar. Further disclosed are devices fabricated according to this method as well as electrically conductive double adhesive tapes utilized in the process.
