Description
非特許文献1には、n型半導体とAu,Pdなど5eV以上の仕事関数を有する金属薄膜とによりショットキー障壁を形成するショットキー型接合光電変換素子が示されている。非特許文献1に記載のような従来のショットキー型接合光電変換素子では、金属薄膜電極において入射光の著しい減衰があるため、光電変換素子としての性能が充分に引き出せないという欠点があり、太陽電池としては実用化できないという欠点があった。
上記目的を達成するために、本発明の光電変換素子は、本発明のショットキー型接合素子を用い、光を電気に変換する変換部がショットキー接合を含んで構成されていることを特徴とする。
本発明の実施形態としての光電変換素子は、ショットキー型接合素子1を用い、光と電気とを相互変換する変換部がショットキー接合を含んで構成されている。
ステップST1において、サファイア(0001)基板2を用意し、ステップST2において、サファイア(0001)基板2上にトリメチルガリウム、アンモニアおよび水素を原料として、有機金属気相成長法を用いて窒化ガリウム(以下、GaN)を厚さ3μmにエピタキシャル成長させてGaN膜3を形成する。実施例1では、GaN膜3を表面に有するサファイア基板2の市販品を用いた。このサファイア基板2は、(株)パウデック社製のn−GaNエピウエファでウエファNo.PT01AB04H26491121のものであり、サファイア基板(0001)面上に非ドープ層厚1μmとドープ層厚2μmとがこの順に積層されており、合計膜厚が3μmであった。
太陽電池1の分光感度測定結果から分かるように、GaNの光学的バンド端波長である360nmを中心として短波長側に向かって急峻に分光感度が増加し、300nmで0.3に達した。
ステップST6においてサファイア基板2を用意し、ステップST7においてサファイア基板2上に無機半導体3としてのGaN膜を設け、ステップST8において無機半導体3としてのGaN膜上に有機導電体4を設けた点は、実施例1のステップST1、ステップST2、ステップST3と同様であるので説明を省略する。
従来、ショットキー障壁を得るために必須とされた電極材料、例えばAu、Pdなどの希少金属や貴金属に比較して入手し易い有機薄膜等の材料により構成できるので、高い実用性を有する。
