BACK-SHEET FOR PHOTOVOLTAIC MODULES COMPRISING BACK-CONTACT SOLAR CELLS

摘要

The present invention proposes a back-contact back-sheet for a photovoltaic module comprising back-contact solar cells. The back-contact back-sheet comprises a substrate (210) having an outer surface exposed toward the air-side of the photovoltaic module and an inner surface opposite said outer surface and facing the inside of the photovoltaic module. The back-contact back-sheet further comprises a layer (220) of an electrically conductive material comprising aluminium adapted to be formed as a connecting circuit (220c) to the electrodes of said solar cells and directly adherent to the inner surface of the substrate (210). The layer of conductive material (220) comprises a protective metal film formed on the surface of the layer of conductive material (220) opposite the surface facing said substrate (210).
