- 2009-2011年度科学研究費助成事業(科学研究費補助金(基盤研究(C)))研究成果報告書 課題番号：21560335 研究代表者：野見山輝明 (鹿児島大学大学院理工学研究科(工学系)助教)光蓄電池は，一つのセルで光発電と蓄電の2つの機能を持つ，光で充電できる蓄電池である。この電極はFTO上のTiO_2多孔膜にFTO側から導電性高分子ポリアニリン(PANi)を電解重合したもので，電解質側のTiO_2層は発電層，下層のTiO_2-PANi複合層が蓄電層となる。それぞれの層厚を光電気化学エッチングや電着時間の制御等で変えて光蓄電性を評価した。その結果，蓄電層が厚くなるとTiO_2-PANi間の電子移動が遅くなり，光蓄電効率が落ちることがわかった。Photorechargeable battery (PRB) is a photovoltaic device having an energy storage function in a single cell. The photoactive electrode of PRB is a bilayer film consisting of bare porous TiO_2 and TiO_2-Polyaniline (PANi) mixture which work as photovoltaic current generator and electrochemical energy storage by ion dedoping, respectively. In this study, photorechargeable quantum efficiency η_q was measured with varying the thickness L_S of TiO_2-PANi mixture. The time constant τ_{TP} for charge transfer from TiO_2 to PANi was about 10^{−1}s which was longer ten times or more than the lifetime of excited electrons within TiO_2, and the τ_{TP} became longer for L_S > 10 μm. These results show that the main rate-limiting factor in the photocharging process is the charge transfer from TiO_2 to PANi.
