CRYSTALLOGRAPHICALLY TEXTURED METAL SUBSTRATE, CRYSTALLOGRAPHICALLY TEXTURED DEVICE, CELL AND PHOTOVOLTAIC MODULE INCLUDING SUCH DEVICE AND THIN LAYER DEPOSITION METHOD

摘要

The invention relates to a crystallographically textured metal substrate (1) comprising a connection surface (2) and a surface (3) for receiving a thin-film deposit, said stallographically-textured metallic substrate (1) being made of an alloy having a face-centered cubic crystalline system and a majority {100} 001 cube crystallographic texture, the surface for receiving the thin-film deposition (3) comprising grains (4) having predominantly {100} crystallographic planes parallel to the surface (3) intended to receive a thin-layer deposit. According to the invention, the alloy is an iron-nickel alloy having a composition comprising, in% by weight relative to the total weight of said alloy: Ni = 30%, Cu 15%, Cr = 15%, Co = 12%, Mn = 5%, S 0.0007%, P 0.003%, B 0.0005%, Pb 0.0001%, the percentages of nickel, chromium, copper, cobalt and manganese being such that the alloy satisfies the following condition: 34% (Ni + Cr + Cu / 2 + Co / 2 + Mn), and the alloy comprises up to 1% by weight of one or more deoxidizing elements chosen from silicon, magnesium, aluminum and calcium, the rest of the elements constituting the alloy being iron and impurities.
