Electrode for photovoltaic cells, photovoltaic cell and photovoltaic module

A photovoltaic system comprising:

• a terminal bar formed into a closed frame, said closed frame having an open area;
• a first photovoltaic element in said open area, said first photovoltaic element having a first electrically conductive surface;
• and
• an electrode comprising:
• an electrically insulating optically transparent film having a planar surface;
• an adhesive layer on said planar surface;
• a plurality of substantially parallel, electrically conductive wires lying over said planar surface of said film and embedded into said adhesive layer, said adhesive layer having a thickness less than a thickness of said wires embedded therein, such that a part of the surfaces of said wires protrudes from said adhesive layer;
• and
• first ohmic contact means for causing said part of the surfaces of said wires protruding from said adhesive layer to make ohmic contact with the first electrically conductive surface of said first photovoltaic element and to make ohmic contact with said terminal bar;
• said adhesive layer being operable to adhesively secure said film to said first electrically conductive surface while said ohmic contact means causes said part of the surfaces of said wires protruding from said adhesive layer to make ohmic contact with said first electrically conductive surface of the first photovoltaic element and said terminal bar.
