化合物系薄膜太陽電池は、例えば、基板上に絶縁層を形成し、絶縁層上にMo層からなる第一の電極層を製膜し、その上に光吸収層としてカルコパイライト型化合物層を被膜し、更に第2の電極層を製膜する。ここで、カルコパイライト型化合物とは、Cu−In−Ga−Se−S系(以下CIS系)に代表される5元系合金である。
そこで本発明の目的は、コーティングやメッキの表面処理、あるいは3%以上のAl添加によらず耐硫化腐食性を具備したAl含有フェライト系ステンレス鋼板およびその製造方法を提供することにある。
MgやGaは、表面活性元素であり、微量添加でも低酸素雰囲気下において選択的に表面に濃化し、更にMgは酸化物を形成し、FeやCrの酸化を抑制してAlを主体とした被膜形成に対して有効に作用する。特に、Mg+Gaのトータル含有量が0.002%を超える場合に顕著な効果を奏でる。

(6)(5)に記載する水素ガスを含む雰囲気中の熱処理に次いで、3〜20重量%の硝酸水溶液中で電解酸洗を行うことにより、前記ステンレス鋼の表面に(1)または(3)に記載する表面被膜を形成させることを特徴とする耐硫化腐食性に優れたAl含有フェライト系ステンレス鋼の製造方法。
(7)太陽電池基板として使用されることを特徴とする、(1)〜(4)のいずれかに記載の耐硫化腐食性に優れたAl含有フェライト系ステンレス鋼。
以下、上記(1)〜(4)、(7)の鋼板に係る発明をそれぞれ本発明という。また、(1)〜(7)の発明を合わせて、本発明ということがある。
本発明のAl含有フェライト系ステンレス鋼は、耐硫化腐食性を発現させるために、上述した鋼成分を有し、更にMg、Mg+Gaを高めてAl主体の被膜を形成するものとする。被膜厚さの上限は100nmとし、生産性を考慮した光輝焼鈍又は光輝焼鈍と同等な効果が得られる熱処理や酸洗を施して100nm以下とすることが好ましい。被膜厚さの下限は特に規定するものではないが、好ましくは硫化水素中の耐硫化腐食性に効果を発揮する3nm以上とする。好ましい膜厚の範囲は3〜30nmである。
Al2s:119eV、Mg1s:1303eV、S2p:160eV
Si2p:153eV、Ti2p3/2:456〜458eV、
Cr2p3/2:576eV Fe2p3/2:710eV
ここで、各元素の濃度は、各スペクトルの積分強度を測定し、CやO、Nの軽元素を除くカチオンイオン換算で求めることができる。
被膜厚さは、同分析装置のArスパッタ法により、Oのプロファイルを測定し、Oの強度が半分の値となる半値幅で求めることができる。
(I)項に記載する成分の鋼において(II)項に記載した表面被膜を形成させるために、以下の諸条件で熱処理することが好ましい。素材のうち鋼板は、薄板、箔、厚中板を対象とし、製造方法は特に規定するものでない。ここで、薄板は0.2mm以上、箔は0.02〜0.2mm、厚中板は6mm以上の板厚を対象にするものとする。鋼の表面粗度は特に規定するものでなく、JIS準拠したBA、2B、2D、No.4、研磨などであれば良い。
これら光輝焼鈍をバッチ炉で実施する場合においては、加熱温度の下限や加熱時間の上限は特に規定するものでなく、例えば、700℃、24時間としても構わない。ここで、本発明の目標とする表面皮膜の形成と耐ガス腐食性を達成できる本発明のステンレス鋼において、当該光輝焼鈍条件に限定されるものでないことは言うまでもない。
No.1〜8は、本発明で規定する成分と表面被膜を有し、H2S中の耐硫化腐食性を達成したものである。No.3、4、7、8は、微量元素Mg+Gaの好適量を含み、表面被膜中の最も好適なAl濃度80%以上と、S量<1%を満たすものであり、顕著な耐硫化腐食性を発現し、評価は「◎」となった。ここで、No.3はGaの添加効果により被膜中のAl濃度が顕著に上昇した。また、No.7、8は、光輝焼鈍雰囲気中に微量の酸素を含有し、被膜中のAl濃度が顕著に上昇した。No.1、2、5、6は、本発明の目標とする被膜組成と耐硫化腐食性が得られ、評価は「○」となった。また、No.5、7、8は、光輝焼鈍後の硝酸電解により被膜中のS濃度が低減した。
鋼No.9〜17は、本発明で規定する鋼成分から外れるものであり、本発明で規定する光輝焼鈍を実施しても本発明の被膜組成を満足せず、目標とする耐硫化腐食性が得られず、評価は「×」となった。
なお、鋼Aについて、光輝焼鈍ではなく、焼鈍酸洗を施したところ、本発明の表面被膜の形成は無く、耐硫化腐食性は「×」であった。
