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) that comprises a connection surface (2) and a surface (3) for receiving a thin layer deposit, said crystallographically textured metal substrate being made of an alloy having a cubic crystalline system with centred faces and a cubic crystallographic structure {100} representing a majority, the surface for receiving the thin layer deposit (3) including grains (4) having for the majority crystallographic planes {100} parallel to the surface (3) for receiving a thin layer deposit. According to the invention, the alloy is an iron-nickel alloy having the following composition in wt % 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 meets the following condition 34 % < (Ni + Cr + Cu/2 + Co/2 + Mn), the alloy containing up to 1 wt % of one or more deoxidising elements selected from silicon, magnesium, aluminium and calcium, the balance of the elements constituting the alloy consisting of iron and impurities.
