Abstract: The invention relates to a photovoltaic article comprising a plurality of photovoltaic cells having first (22) and second (24) electrical connector segments in contact with the top side (18) of a first cell (10) and the backside (16) of a second adjacent cell (12). The materials used to form the electrical connector segments are selected to minimize corrosion, maximize contact area, and lower contact resistance over the lifetime of the article.

Abstract: The invention is a method of forming a cadmium sulfide based buffer on a copper chalcogenide based absorber in making a photovoltaic cell. The buffer is sputtered in two steps the first being at low rates or relatively high pressures and the second at high rates or relatively low pressures. The resulting cell has good efficiency and according to one embodiment is characterized by a narrow interface between the absorber and buffer layers. The buffer is further characterized according to a second embodiment by a relatively high oxygen content.

Abstract: An article of manufacture includes a PV element having a conductive layer positioned on a light-incident side of the PV element, a conductor electrically coupled to the conductive layer, and a conductive particle matrix interposed between the conductor and the conductive layer at a number of positions on the conductive layer. The article further includes a carrier film positioned on the light-incident side of the PV element, and a non-conductive adhesive, where the adhesive and the conductor are positioned between the carrier film and the conductive layer.
