Photovoltaic product, comprising: a foil with a photovoltaic layer stack and an electrically conductive layer stack that supports the photovoltaic layer stack and that in an operational state provides for a transport of electric energy generated by the photovoltaic layer stack to an external load, wherein the electrically conductive layer stack comprises: - a first and a second electrically conductive layer (21, 22) and an electrically insulating layer arranged between the first and the second electrically conductive layer, - the first electrically conductive layer comprising a first electrically conductive background domain and a first plurality of laterally distributed, mutually distinct contact areas which are electrically insulated from the first electrically conductive background domain; - the second electrically conductive layer comprising a second electrically conductive background domain and a second plurality of laterally distributed, mutually distinct contact areas which are electrically insulated from the second electrically conductive background domain; - a first plurality of laterally distributed electrically conducting vias that electrically interconnect respective ones of the first plurality of contact areas with the second electrically conductive background domain; - a second plurality of laterally distributed electrically conducting vias that electrically interconnect respective ones of the second plurality of contact areas with the first electrically conductive background domain; wherein the photovoltaic layer stack has first electrical contacts (P1, P2) of a first polarity that are electrically connected to the first electrically conductive background domain and has second electrical contacts (N1, N2) of a second polarity opposite to said first polarity that are electrically connected to the first contact areas, and wherein the second electrically conductive background domain and one or more of the second contact areas serve as electric contacts for the output clamps. a foil with a photovoltaic layer stack and an electrically conductive layer stack that supports the photovoltaic layer stack and that in an operational state provides for a transport of electric energy generated by the photovoltaic layer stack to an external load, wherein the electrically conductive layer stack comprises: - a first and a second electrically conductive layer (21, 22) and an electrically insulating layer arranged between the first and the second electrically conductive layer, - the first electrically conductive layer comprising a first electrically conductive background domain and a first plurality of laterally distributed, mutually distinct contact areas which are electrically insulated from the first electrically conductive background domain;
