Liquid-containing photovoltaic element

Liquid-containing photovoltaic element (1;

• 10, 20), comprising a plate work electrode and a plate counter-electrode adhered thereto by means of a vapour and liquid-tight peripheral edge, wherein the work electrode and the counter-electrode are each formed on a flat substrate (2, 2′;
• 12, 12′) provided with an electrically conductive layer (3, 3′;
• 13, 13′) and wherein a liquid (8) is received into a space between the work electrode, the counter-electrode and the peripheral edge, characterized in that a system of mutually connected electrical conductors (4, 4′;
• 14, 14′) is provided on the conductive layer (3, 3′;
• 13, 13′) of each of the substrates (2, 2′;
• 12, 12′) for the work electrode and the counter-electrode, which conductors (4, 4′;
• 14, 14′) have a mirror-symmetrical form relative to each other and are provided with a layer (5, 5′;
• 15, 15′) of an electrically insulating material, which layer (5, 5′) electrically isolates the conductors (4, 4′) and provides the vapour and liquid-tight peripheral edge, in which layer (5, 5′;
• 15, 15′) there is provided at least one recess (11, 11′;
• 21, 21′) for an electrical contact (9, 9′;
• 19, 19′) on a conductor of the conductors (4, 4′;
• 14, 14′) in a manner such that the electrical contact (9, 9′:
• 19, 19′) is left clear by the electrically insulating material over the conductors (4, 4′:
• 14, 14′) so that it contacts the conductor of the conductors, and in that the electrically insulating material is an adhesive material (5, 5′;
• 15, 15′).
