Description
図1は、本発明の一実施形態に係る光電変換装置の一例を示す斜視図であり、図2はその断面図である。光電変換装置11は、基板1上に複数の光電変換セル10が並べられて互いに電気的に接続されている。なお、図1においては図示の都合上、2つの光電変換セル10のみを示しているが、実際の光電変換装置11においては、図面左右方向、あるいはさらにこれに垂直な方向に、多数の光電変換セル10が平面的に(二次元的に)配設されていてもよい。
次に、上記光吸収層としての第1の半導体層3の製造方法について説明する。先ず、第1の半導体層3がI−III−VI族化合物を含む光吸収層である場合の例を説明する。第1の電極層2を有する基板1上に、金属元素(I−B族元素およびIII−B族元素)およびカルコゲン元素を含む原料溶液を、スピンコータ、スクリーン印刷、ディッピング、スプレー、ダイコータ等によって膜状に被着させることによって、金属元素およびカルコゲン元素を含む第1の皮膜を形成する。なお、カルコゲン元素とは、VI−B族元素のうち、S、Se、Teをいう。また、第1の皮膜を、上記原料溶液を用いた皮膜形成を繰り返して複数層の積層体としてもよい。あるいは、第1の皮膜を、異なる組成の原料溶液を用いて皮膜形成をすることによって、組成の異なる複数層の積層体としてもよい。
上記の第1の方法以外にも光吸収層の配向性を適度にしてピーク強度比IB/IAを3以上9以下にすることができる。例えば、第1の電極層2を有する基板1上に、I−B族元素、III−B族元素およびカルコゲン元素が1つの有機錯体分子中に含まれる単一源錯体(単一源錯体の例としては米国特許第6992202号明細書を参照)を含む原料溶液を、スピンコータ、スクリーン印刷、ディッピング、スプレー、ダイコータ等によって膜状に被着することによって第1の皮膜を形成する。この第1の皮膜は、異なる組成比の複数の積層体であってもよい。
まず、原料溶液を以下のようにして調整した。
次に、ガラス基板の表面に、Moを含む下部電極層が成膜されたものを用意した。そして、窒素ガスの雰囲気下において下部電極層の上に上記原料溶液をブレード法によって塗布して、第1の皮膜を形成した。
上記試料1の第1の半導体層の作製と同様にして、Moを含む下部電極層の上に上記原料溶液をブレード法によって塗布して、第1の皮膜を形成した。
ガラス基板の表面に、Moを含む下部電極層が成膜されたものを用意した。そして、この下部電極層の上に、CuとInとGaとSeとを蒸着してCIGSから成る、試料3としての第1の半導体層を形成した。
第1の皮膜の形成において、上記原料溶液に代えて以下の第2の原料溶液を用いた。第2の原料溶液の作製は以下のようにして作製した。
次に、上述のように作製された試料1〜試料4としての第1の半導体層の上に、第2の半導体層と上部電極層とを順に形成して、光電変換装置を作製した。
