から算出することができる。
く、本発明の趣旨を逸脱しない限り適宜変形が可能である。
透明導電性基板を準備し、その上に酸化チタンを含む下地層を形成した。この下地層の上に、アナターゼ型酸化チタン粒子と、有機分散剤(有機溶媒)と、バインダーと、粘度調整剤(エチルセルロース)とを含有する酸化チタンペーストを印刷法により塗布した。塗布されたペーストを150℃で乾燥した後、電気炉内で450℃に加熱して、多孔質酸化チタン層を形成させた。
作製した多孔質酸化チタン層を剥ぎ取って回収した約0.1gのサンプルを用いて、液体窒素温度における窒素ガスの吸着等温線を測定した。細孔の形状を円筒形と仮定したBJH法によって、測定された吸着側の吸着等温線から細孔分布を算出した。測定はQUANTA CHROME社製のAUTOSORB−1を用いて行った。図4の「a」はNo.図4の「b」はNo.12、図5はNo.13、図6はNo.14、図7はNo.15の細孔分布である。No.13〜15の各細孔分布は、40〜100nmの範囲内で最大値を示した。
各太陽電池の発電効率を測定した。図10は各サンプルの発電効率を示すグラフである。図10に示されるように、No.13、14、15、16及び21の色素増感型太陽電池は、No.11、12と比較して著しく高い発電効率を達成した。
