Substrate and collector grid structures for integrated photovoltaic arrays and process of manufacture of such arrays

A device comprising multiple photovoltaic cells and an additional interconnection structure to achieve a series interconnection between two of said photovoltaic cells;

• wherein,
• said two photovoltaic cells each have a cell body, said body comprising a light incident top surface formed by a transparent or translucent conductive material and further comprising semiconductor material overlaying conductive material forming a conductive bottom surface, said conductive bottom surface facing away from said light incident surface, said cell further comprising terminal edges defined by boundaries of said semiconductor material;
• said additional interconnection structure comprising,
• a sheetlike substrate, said substrate having overlapping a first and second substrate surfaces, said first surface facing in a direction opposite and away from said second surface;
• said interconnection structure further comprising multiple structural portions, a first of said portions is transparent or translucent and has a first pattern comprising electrically conductive material positioned on said first surface, and a second of said portions has a second pattern comprising electrically conductive material positioned on said second surface, wherein said first and second patterns are in electrical communication;
• said first structural portion overlaying said light incident surface of a first of said cells such that said first substrate surface of said first portion and said light incident surface face each other and said first pattern contacts said light incident surface;
• said second pattern and said conductive bottom surface of a second of said cells facing each other such that said second pattern is in contact with said bottom conductive surface of said second cell.
