FERRITIC STAINLESS STEEL FOIL FOR SOLAR CELL |
| 摘要 |
A ferritic stainless steel foil for a solar cell substrate excellent in terms of threading performance. The ferritic stainless steel foil for a solar cell substrate may have a chemical composition containing, by mass %, Cr: 14% or more and 24% or less and Nb: 0.1% or more and 0.6% or less, and optionally further containing Mo: 2.0% or less, a Vickers hardness of Hv250 or more and Hv450 or less, and a Vickers hardness of Hv250 or more and Hv450 or less after the substrate has undergone an optical absorber layer growth process in which the substrate is held in a temperature range of 450° C. or higher and 650° C. or lower for a duration of 1 minute or more. |
