Abstract
【解決手段】 電子供与性材料とホール供与性材料を混合した発電層1を、少なくとも一方は透明な正極2と負極3の二つの電極の間に設けて形成される有機発電素子に関する。発電層1と正極2との間に、正極2より仕事関数が大きい無機物の層4を設けることによって、発電層1からの電荷の取り出しの効率を高めることができる。

Description
正極2を形成するITO(仕事関数4.8eV)膜付きの倉元製作所(株)製の硝子基板5を用い、これをアセトン、イソプロピルアルコール(共に(株)関東化学製)、セミコクリーン(フルウチ科学社製)、超純水で各10分間超音波洗浄を行ったのち、さらにイソプロピルアルコールの蒸気で洗浄し、乾燥させた。次に、大気圧プラズマ表面処理装置(松下電工(株)製)を用いて、3分間、このITO膜付き基板5の表面処理を行なった。
実施例1と同様に洗浄・表面処理をしたITO膜付き硝子基板5を用い、ITOの正極2の上に、五酸化二バナジウム(V2O5、仕事関数5.4eV)を真空蒸着することによって、膜厚15nmの無機物層4を形成した。後は実施例1と同上にして、有機発電素子を得た。
実施例1と同様に洗浄・表面処理をしたITO膜付き硝子基板5を用い、ITOの正極2の上に、カーボンのターゲット(高純度化学研究所製)を使用したスパッタリング装置(アネルバ社製)でスパッタリングをすることによって、膜厚10nmのアモルファスカーボン膜(a−C、仕事関数5.2eV)からなる無機物層4を形成した。後は実施例1と同上にして、有機発電素子を得た。
正極2と発電層1の間に層を設けないようにした以外は、実施例1と同様にして有機発電素子を得た。
無機物層4の代りに、有機物のポリエチレンジオキシチオフェン:ポリスチレンスルフォネート(PEDOT:PSS)(スタルク社製)の50nm厚の層を、正極2と発電層1の間に形成するようにした以外は、実施例1と同様にして有機発電素子を得た。
無機物層4の代りに、銀(Ag、仕事関数4.5eV)の5nm厚の層を、正極2と発電層1の間に形成するようにしたこと以外は、実施例1と同様にして有機発電素子を得た。
