(光電極層の作製)
電極基板として片面にFTO電極皮膜が形成されたFTOガラスを用いて、このFTOガラスの電極面に、酸化チタンペースト(日揮触媒化成株式会社製、PST−18NR)をスキージ法にて塗布した。125℃で6分乾燥後、325℃で5分、375℃で5分、450℃で15分、500℃で15分焼成し、膜厚10μmの酸化チタン膜を形成した。この酸化チタン膜が形成されたFTOガラスを、実施例1〜13および比較例1〜6で得られた各色素を濃度が200μMになるようにアセトニトリル/t−ブチルアルコール=1/1に溶解させ、この溶液に90分間浸漬し光電変換層を作製した。なお、添加剤としてこの色素溶液にコール酸濃度が0.4mMになるようにコール酸を加えた。
3−メトキシプロピオニトリル溶液に、1,2−ジメチル−3−プロピルイミダゾリウムヨージドとヨウ素とヨウ化リチウムと4−t−ブチルピリジンを1,2−ジメチル−3−プロピルイミダゾリウムヨージド(0.60M)、ヨウ素(0.05M)、ヨウ化リチウム(0.10M)、4−t−ブチルピリジン(0.05M)となるように混合し、電解質液とした。この電解質液を上記電極基材と同じFTOガラスを用いた対向基板と先述の光電極層との間に配し電解質層を形成した。
上記で作製した各光電変換素子(受光面積0.20cm2)に分光計器株式会社製「CEP−2000」を用いて100mW/cm2の照射強度で光を当てて、光電変換素子の短絡電流(mA)と開放電圧(V)を測定し、短絡電流と受光面積より短絡電流密度(mA/cm2)を求めた。次いで、光電変換素子の電極間に接続する抵抗値を変化させて最大電力Wmax(mW)を観測し、形状因子FFと光電変換効率(%)を下記計算式により求めた。酸化チタンを用いた場合の評価結果を表1に示す。また、光電極層の作製において酸化チタンを酸化亜鉛に変えた場合の評価結果を表2に示す。
また、表2に示すように、酸化亜鉛においても光電変換効率の大きな改善が認められた。
