Description
第1の実験では、上述の実施形態に倣って光蓄電池を作製し、光蓄電電極の形成の際の紫外光エイジングの有無による光起電力Vph及び光充電後の蓄電電荷量Qphの変化を調査した。光起電力Vph及び蓄電電荷量Qphの測定については、光蓄電電極を開放のまま光充電として15分間、キセノンアークランプ光を照射した後の電位変化を光起電力Vphとし、その後、暗下にて1kΩの定抵抗を介して対極と接続し、放電を行った。そして、この際の放電電荷量を蓄電電荷量Qphとした。このような光による充電及び定負荷放電の手順を1サイクルとし、蓄電電荷量Qph及び光起電力Vphの測定を5サイクル繰り返した。7時間の紫外光エイジングを施して傾斜構造とした光蓄電電極、及びこのような紫外光エイジングを施さずに均一構造のままとした光蓄電電極の光起電力Vph及び蓄電電荷量Qphを、夫々図4A及び図4Bに示す。図4A及び図4B中の●が均一構造の光蓄電電極を用いた場合の結果を示し、○が傾斜構造の光蓄電電極を用いた場合の結果を示す。但し、ここでは、電極作製の直後である1サイクル目の蓄電電荷量Qph及び光起電力Vphは、光充電による放電以外の放電電流も観測されるため、除外してある。
第2の実験では、紫外光エイジングの前後での光触媒粒子12と高分子13との複合体の変化を光学的に観察した。紫外光エイジング前の複合体の状態を図5Aに示し、24時間の紫外光エイジング後の複合体の状態を図5Bに示す。
