TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: In the article, no portion of the first conductive material or the additional conductive material is positioned outside the outer boundaries of the substrate. The light incident first surface of the first cell is formed by an unbroken layer of light transmitting electrically conductive material. The light transmitting electrically conductive material comprises a conductive metal oxide. The light incident first surface of the first cell is essentially planar so that for all intents and purposes it can be characterized as flat. The ohmic electrical communication exist between the light transmitting electrically conductive material forms the light incident first surface of the first cell and the first electrically conductive material of the pattern. A monolithic conductive material extends throughout the entire pattern overlaying a preponderance of the light incident first surface of the first photovoltaic cell and the monolithic conductive material is also common to and further contributes to both the first and second portions of the additional conductive material. The monolithic conductive material comprises a continuous metal. At least a portion of the exterior downward facing bottom side of the substrate associated with the collection region is formed by a layer of adhesive material which is adhesively bonded in direct contact with the light incident first surface of the first cell. The pattern comprises multiple substantially parallel line segments comprising metallic material, where connecting metallic material extends to connect two adjacent line segments, the connecting metallic material extends only from distal ends of the two adjacent parallel line segments, and the metallic material associated with the two adjacent parallel line segments and the connecting metallic material comprises a monolithic material common to the two adjacent parallel line segments and the connecting material. The portion of the first electrically conductive material in direct physical contact with the light incident first surface of the first cell comprises an electrically conductive coating over a base structure. The coating comprises nickel or tin and is absent polymeric material. The coating comprises a polymeric adhesive. The first photovoltaic cell comprises a self supporting metal based foil, and the photovoltaic semiconductor material layer overlays the full expanse of an upward facing surface of the metal based foil. The electrical communication between the first electrically conductive material of the pattern and the second portion of additional conductive material on the exterior upward facing top substrate side is established using holes extending through the substrate from the bottom substrate side to the top substrate side, where the first portion of the additional electrically conductive material extends through the holes to electrically connect the first electrically conductive material of the pattern positioned on the exterior bottom substrate side and the second portion of additional electrically conductive material on the exterior top side of the substrate. The adhesive material is a laminating adhesive whose adhesive affinity for the light incident first surface is activated by elevated temperature and pressure whereby the adhesive material becomes fluid when the temperature and pressure are increased sufficiently above ambient.

The semiconductor layer has first surface intended to face toward a light source, and terminal edges defining boundaries encompassing an area associated with the first surface. The first photovoltaic cell further comprises a light transmitting material layer which forms an upward facing top light incident surface, where the light transmitting material does not extend outside the boundaries encompassing the area of the first semiconductor surface such that a line normal to the top light incident surface passing through any point of the top light incident surface also passes through the photovoltaic semiconductor layer. The light transmitting material layer forming the top light incident surface of the first photovoltaic cell comprises a transparent or translucent conductive metal oxide. The light transmitting material layer forming the top light incident surface of the first photovoltaic cell comprises conductive material particles dispersed in a polymeric matrix. The second photovoltaic cell has a bottom surface facing downward and away from a top light incident surface, and a portion of the downward facing bottom surface is formed by a metallic layer.
