This invention comprises manufacture of photovoltaic cells by deposition of thin film photovoltaic junctions on 
metal foil substrates. The photovoltaic junctions may be 
heat treated if appropriate following deposition in a continuous fashion without deterioration of the 
metal support structure. In a separate operation, an 
interconnection substrate structure is provided, optionally in a continuous fashion. Multiple photovoltaic cells are then laminated to the 
interconnection substrate structure and conductive joining methods are employed to complete the array. In this way the 
interconnection substrate structure can be uniquely formulated from 
polymer-based materials employing optimal 
processing unique to polymeric materials. Furthermore, the photovoltaic junction and its 
metal foil support can be produced in bulk without the need to use the expensive and intricate 
material removal operations currently taught in the art to achieve series interconnections.
