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(2次元的に)配設されていてもよい。
次に、上記構成を有する光電変換装置11の製造方法について説明する。ここでは第1の半導体層3がCIGSの場合について説明する。まず、ガラス等から成る基板1の主面に、スパッタリング法等が用いられてMo等から成る下部電極層2が所望のパターンに形成される。
なお、本発明は上述の実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲において種々の変更、改良などが可能である。
