Abstract: In a solar cell interconnector (2?,102, 202, 302, 402) with at least two layers, comprising a first, substrate layer (20, 120, 220, 320, 420) and a second, electrically conductive layer (21, 121, 221, 321, 421), the first, substrate layer (20, 120, 220, 320, 420) consists of a polymeric material and the second, electrically conductive layer (21, 121, 221, 321, 421) consists of a metal material deposited on the first, substrate layer (20, 120, 220, 320, 420).

Abstract: A high electrical conductive, high temperature stable foil material, a process for the preparation of such a high electrical conductive, high temperature stable foil material, a solar cell interconnector including the high electrical conductive, high temperature stable foil material as well as the use of the high electrical conductive, high temperature stable foil material and/or the solar cell interconnector in solar power, aircraft or space applications. The high electrical conductive, high temperature stable foil material includes an aluminium alloy that has at least two elements selected from the group of scandium (Sc), magnesium (Mg), zirconium (Zr), ytterbium (Yb) and manganese (Mn).
