透明電極として膜厚150nmのITOを片面に設けたITO付きガラス基板を用い、このITO付きガラス基板のITOの表面に、PEDOT溶液(Bayer社製「AI4083」)をスピンコート法にて3000rpm、1分の条件で塗布することによって、膜厚30nmのPEDOTからなる正孔輸送層を形成した。
実施例1と同じITO付きガラス基板を用い、実施例1と同様にして正孔輸送層を形成した。次にアクセプター材料として実施例1と同じフラーレン誘導体を、ドナー材料として導電性高分子のP3HT(ポリ3ヘキシルチオフェン)を用い、フラーレン誘導体とP3HTを質量比1:4で混合してクロロベンゼンに溶解することによって、ブレンド溶液を調製し、このブレンド溶液を正孔輸送層の表面にスピンコート法にて4000rpm、40秒の条件で塗布することによって、膜厚80nmの第1の有機太陽電池を形成する光電変換層を形成した。
実施例1において、再結合層を、Al膜からなる導電層とPEDOT膜からなる導電層の2層で形成する代りに、Al膜からなる導電層のみで形成するようにした。その他は、実施例1と同様にして積層型有機太陽電池を得た。
実施例1において、再結合層を、Al膜からなる導電層とPEDOT膜からなる導電層の2層で形成する代りに、PEDOT膜からなる導電層のみで形成するようにした。その他は、実施例1と同様にして積層型有機太陽電池を得た。
実施例1において、再結合層を、Al膜からなる第1の導電層とPEDOT膜からなる第2の導電層で形成する代りに、Auの真空蒸着による膜厚5nmのAu膜からなる第1の導電層と、Agの真空蒸着による膜厚5nmのAg膜からなる第2の導電層で形成するようにした。その他は、実施例1と同様にして積層型有機太陽電池を得た。尚、Auで形成した第1の導電層の仕事関数は4.6eV、Agで形成した第2の導電層の仕事関数は4.5eVである。
