Description
非特許文献2:Appl.Phys.Lett.96,043307 (2010)
図1は、本発明の実施の形態1による光電変換素子31の模式断面図である。光電変換素子(以下、素子)31は、導電性の第1電極層3と、光電変換層(以下、変換層)4と、第2電極層7とを有する。第1電極層3は、導電性を有する第1基材1と、第1基材1上に形成された粗膜層2とを含む。変換層4は粗膜層2上に、第1基材1の表面全体を覆うように形成されている。第2電極層7は変換層4上に形成されている。素子31は光を電気エネルギーに変換することができる。
(1)第1基材1を蒸着槽内に配置して0.01〜0.001Paの真空状態に保つ。
(2)第1基材1の周辺に、酸素ガスに対してアルゴンガスの流量を2〜6倍にした不活性ガスを流入して、第1基材1の周辺の圧力を10〜30Paの状態にする。
(3)第1基材1の温度を150〜300℃の範囲に保つ。
(4)蒸着源にアルミニウムを配設した状態で真空蒸着により粗膜層2を形成する。
Pは水銀を空孔内に充填するために加える圧力、Dは空孔径(直径)、γは水銀の表面張力(480dyne・cm−1)、θは水銀と細孔壁面の接触角である。空孔径の最頻値は、空孔径Dの分布のピーク値である。
図3は、本発明の実施の形態2による光電変換素子(以下、素子)33の模式断面図である。素子33は、図1に示す実施の形態1の構造に対し、変換層4と導電層5との界面に正孔輸送層(以下、輸送層)8を有している。すなわち、素子33は、変換層4と導電層5との間に輸送層8を有している。これ以外の構成は実施の形態1と同様である。
図4は、本発明の実施の形態3による光電変換素子(以下、素子)34の模式断面図である。素子34は、図1に示す実施の形態1の構造において、変換層4に代えて光電変換層(以下、変換層)24を有する。第1電極層3と第2電極層7との間に電界を印加すると、第2電極層7より変換層24内に移動した電荷(正孔)と、導電層5から変換層24内に注入された電子が結合し発光する。このように素子34は電気エネルギーを光に変換することができる。それ以外の構成は実施の形態1と同様である。
