Photovoltaic module with back contact foil

A photovoltaic module comprising a plurality of photovoltaic units each having a positive contact terminal and a negative contact terminal, and a single layer back contact substrate,

• wherein the single layer back contact substrate comprises
• a positive surface part electrically connected to the positive contact terminal of each of the plurality of photovoltaic units,
• a negative surface part electrically connected to the negative contact terminal of each of the plurality of photovoltaic units, and
• the photovoltaic module further comprising at least one contact bridge in a layer of the photovoltaic module overlaying the single layer back contact substrate, the at least one contact bridge providing an electrical connection between two electrically separated sub-parts of the negative surface part or between two electrically separated sub-parts of the positive surface part, the contact bridge crossing a sub-part of opposite polarity between said two electrically separated sub-parts,
• the photovoltaic module further comprising a positive terminal electrically connected to the positive surface part, and a negative terminal electrically connected to the negative surface part, wherein the positive surface comprises multiple positive conductive paths from one of the photovoltaic units towards the associated positive terminal and the negative surface part comprises multiple negative conductive paths from said one of the photovoltaic units towards the associated negative terminal, wherein the multiple positive conductive paths are separated laterally by at least one other photovoltaic unit, and wherein the multiple negative conductive paths are separated laterally by at least one other photovoltaic unit.
