Crystallographically textured metal substrate, crystallographically textured device, cell and photovoltaic module comprising such a device, and thin layer deposition procedure

摘要

Crystallographically textured metal substrate (1) comprising a connecting surface (2) and a surface (3) intended to receive a thin layer deposit, said metallographically textured metal substrate (1) being constituted by an alloy having a cubic crystalline system of centered faces and a crystalline texture in a cube {100} 001, comprising the surface intended to receive the thin-layer tank (3) grains (4) that mostly have crystallographic planes {100} parallel to the surface ( 3) intended to receive a thin layer deposit, characterized in that: - the alloy is an iron-nickel alloy having a composition comprising, in% by weight with respect 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 in nickel, chromium, copper, cobalt and manganese are such that aleac ion satisfies the following condition: and - the alloy comprises up to 1% by weight of one or more deoxidizing elements selected from silicon, magnesium, aluminum and calcium, the rest of the elements constituting the iron alloy being e impurities
