Description
全自動ガス吸着測定装置(オートソープ−1、湯浅アイオニクス製)を用いて、BET法(気体吸着法)により、二酸化チタン半導体膜の比表面積を測定した。比表面積はBET1点法と多点法により、細孔分布はBJH法により算出した。
増感色素を吸着させた電極をエタノールのアルカリ性溶液に2時間浸漬し、増感色素を脱色させた。上記エタノールのアルカリ性溶液の紫外可視スペクトルを紫外可視分光光度計(U−3310、日立製作所製)を用いて測定した。次に、増感色素の検量線に基づき、吸収強度から吸着量を換算した。
ポテンショスタット(Potentiostat/Galvanostat 2090、東方技研製)を用いて、太陽電池の光電流密度Jsc(mA・cm−2)、開放電圧Voc(mV)を測定し、その曲線から、フィルファクターFF及び光電変換効率(%)を求めた。
市販の二酸化チタン粒子(P25、Nippon Aerosil社、平均粒子径約25nm、比表面積55m2/g、アナターゼ75%、ルチル25%)(3g)に、平均分子量が600のポリエチレングリコール(5.01g)、エタノール(7.5mL)、二酸化ジルコニウム(30g)を加え、ペイントシェーカーで4時間振り混ぜて分散させた後、エタノールを加熱によって除去して、二酸化チタン半導体膜形成用塗布剤としてのペーストを調製した。次に、このペーストを用いて、実施例1と同様にして太陽電池Cを製造した。
市販のアナターゼ型チタンペースト(Solaronix社、Ti−Nanoxide D)を用いて、実施例1と同様にして太陽電池Dを製造した。製造した太陽電池Dは実施例1と同様にして電池性能を評価した。その結果を図1及び表1に示す。
脱イオン蒸留水(7mL)に、上記〔実施例1〕で得られた酸素欠陥構造を有する酸化チタン粉末(3g)と、アセチルアセトン(0.1mL)を加え、ペイントシェーカーで4時間振り混ぜて分散させ、界面活性剤Triton X−100(0.1ml)を添加して、二酸化チタン半導体膜形成用塗布剤としてのペーストを調製した。次に、このペーストを用いて、実施例1と同様にして太陽電池Eを製造した。
アルファーテルピネオール(3.65g)とエチルセルロース(0.45g)との混合溶液に、上記〔実施例1〕で得られた酸素欠陥構造を有する酸化チタン粉末(1g)を加え、ペイントシェーカーで4時間振り混ぜて分散させることにより、二酸化チタン半導体膜形成用塗布剤としてのペーストを調製した。次に、このペーストを用いて、実施例1と同様にして太陽電池Fを製造した。
