This invention comprises deposition of thin film photovoltaic junctions on metal substrates which can be heat treated following deposition in a continuous fashion without deterioration of the metal support structure. In a separate operation an interconnection substrate structure is produced in a continuous roll-to-roll fashion. In this way the interconnection substrate structure can be uniquely formulated from polymer-based materials since it does not have to endure high temperature exposure. Cells comprising the metal foil supported photovoltaic junctions are then laminated to the interconnection substrate structure. Conductive interconnections are deposited to complete the array. The conductive interconnections can be accomplished with a separately prepared interconnection component. The interconnected array is produced using continuous roll-to-roll processing which avoids the need to use the expensive and intricate material removal operations currently taught in the art to achieve electrical interconnections among arrays of photovoltaic cells.

The invention relates to a process for the production of a layer structure of a nitride semiconductor component on a silicon surface, comprising the steps:

• • provision of a substrate that has a silicon surface;
  • deposition of an aluminium-containing nitride nucleation layer on the silicon surface of the substrate;
  • optional: deposition of an aluminium-containing nitride buffer layer on the nitride nucleation layer;
  • deposition of a masking layer on the nitride nucleation layer or, if present, on the first nitride buffer layer;
  • deposition of a gallium-containing first nitride semiconductor layer on the masking layer,

wherein the masking layer is deposited in such a way that, in the deposition step of the first nitride semiconductor layer, initially separate crystallites grow that coalesce above a coalescence layer thickness and occupy an average surface area of at least 0.16 μm² in a layer plane of the coalesced nitride semiconductor layer that is perpendicular to the growth direction.
