公知のルテニウム錯体誘導体より吸収領域の広い本錯体が光電変換用色素として使用可能であることを見いだし、この知見に基づいて本発明をなすに至った。
即ち、この出願は以下の発明を提供するものである。
〈1〉式(I)で表されるルテニウム錯体化合物。
RuLL’X (I)
(式中、Lは3個のカルボキシル基を置換基として有する2,2’;6’,2’’−テルピリジン、L’はアルキル基で置換されてもよいエチレンジアミン、Xはハロゲン化物、シアノ基、イソチオシアノ基、チオシアノ基、チオラートから選択される単座配位子である。)
〈2〉導電性表面に形成された酸化物半導体膜に〈1〉に記載の式(I)で表されるルテニウム錯体化合物が、吸着したものであることを特徴とする色素増感酸化物半導体電極。
〈3〉〈2〉に記載の電極と、その対極と、それらの電極に接触するレドックス電解質とから構成されることを特徴とする太陽電池。
この錯体は、暗緑色の固体でありレクトロスプレー質量分析装置による測定値として、C21H19N6O6RuSの分子量に相当する585(M+)を示す。重水中の核磁気共鳴スペクトルとして、1H−NMR(δ、400MHz)8.95(d,J=6Hz,2H)、8.77(s,2H)、8.75(s,2H)、8.00(dd,J=2Hz,J=6Hz,2H)、5.70(t,2H)、4.7−4.9(溶媒ピークとの重なりのため確認困難)、3.23(t,2H)、2.45(t,2H)、可視吸収スペクトルとしてモル吸光係数5400M−1cm−1の吸収極大を560nmに示す。
このルテニウム錯体を導電性ガラス表面に作成した酸化チタン多孔質膜に吸着させることにより可視光応答性の電極を構成した。導電性ガラス表面に白金を蒸着した対電極との間に、0.1Mヨウ化リチウム、0.05Mヨウ素、0.6M1.2-ジメチル-3-プロピルイミダゾリウムヨージド、アセトニトリルから構成される電解質溶液をはさみ太陽電池を構成する。その結果AM1.5の擬似太陽光照射下において、短絡電流18.7mA/cm2、開放電圧0.57V、FF69%の光電流を取り出すことが出来た。
