Description
本発明において、基材として使用する鋼箔については、太陽電池の基板で必要とされる耐食性を有する限り特段の制約は無い。ただし、Cr量が7質量%未満では長期使用時の耐食性が不足しており、基板の腐食の問題があり、40質量%を超えると鋼箔製造における中間製品である熱延鋼板の靭性が著しく低下し、製造ラインを通板することができなくなるという問題がある。そのため、Cr量は7〜40質量%にする必要がある。こうした鋼としては、SUS430(17%Cr鋼)、SUS447J1(30%Cr-2%Mo鋼)、9%Cr鋼、20%Cr-5%Al鋼、SUS304(18%Cr-8%Ni鋼)などを挙げられる。
Cは、鋼中のCrと結合して、耐食性の低下をもたらすため、低いほど望ましいが、0.12%以下であれば耐食性を著しく低下させることはない。このため、0.12%以下が好ましく、より好ましくは0.04%以下である。
Siは、脱酸に用いる元素であるが、過剰に含有されると、延性の低下をもたらすため、2.5%以下が好ましい。より好ましくは1.0%以下である。
Mnは、Sと結合してMnSを形成し、耐食性を低下させるため、1.0%以下が好ましい。より好ましくは0.8%以下である。
上述したとおり、Sは、Mnと結合してMnSを形成し、耐食性を低下させるため、0.030%以下が好ましい。より好ましくは0.008%以下である。
Pは、延性の低下をもたらすため、低いほど望ましいが、0.050%以下であれば延性を著しく低下させることはない。このため、0.050%以下が好ましく、より好ましくは0.040%以下である。
Cr量が7%未満では長期使用時の耐食性が不足しており、基板の腐食の問題があり、40%を超えると鋼箔製造における中間製品である熱延鋼板の靭性が著しく低下し、製造ラインを通板することができなくなるという問題がある。そのため、Cr量は7%以上40%以下にする必要がある。
Nb、Ti、Zrはいずれも、鋼中のC、Nを炭化物や窒化物、あるいは炭窒化物として固定し、耐食性を改善するのに有用な元素である。ただし、1.0%を超えて含有すると延性の低下が顕著となるので、これらの元素は単独添加または複合添加いずれの場合も1.0%以下に限定する。なお、これらの元素の添加効果を十分に発揮させるには、0.02%以上含有させることが好ましい。
Alは、脱酸に用いられる元素であるが、過剰に含有されると延性の低下をもたらすため、0.20%以下が好ましい。より好ましくは、0.15%以下である。
Nは、鋼中のCrと結合して、耐食性の低下をもたらすため、低いほど望ましいが、0.05%以下であれば耐食性を著しく低下させることはない。このため、0.05%以下が好ましい。より好ましくは0.015%以下である。
Moは、鋼箔の耐食性、特に局部腐食性を改善するのに有効な元素であり、この効果を得るためには、0.02%以上含有させることが好ましい。一方、4.0%を超えて含有すると延性の低下が顕著となるので、上限は4.0%が好ましい。より好ましくは2.0%以下である。
本発明である太陽電池基板用鋼箔は、Crを7〜40質量%含み、厚さ1mm以下の光輝焼鈍後または焼鈍し、酸洗後の鋼板を、圧下率50%以上で冷間圧延することによって製造できる。これは、図1に示すように、SUS430などでは圧下率を50%以上にすれば930MPa以上の引張強度が得られるためである。圧下率を70%以上にすれば1000MPa以上の引張強度が得られる。
