项目摘要

液体を多量に含みながら硬い多糖類固体中で,分子やイオンの自己拡散や光励起状態の電子移動,あるいは挿入した電極界面での電荷移動が,液体中と同様に起こることを明らかにした.この固体をレドックス溶液を閉じ込める材料として用いて色素増感太陽電池(DSSC)を構築し,固体系の色素増感太陽電池,さらには全プラスティック型の色素増感太陽電池を構築し,交流インピーダンス法により,各電荷移動過程を解析した.二酸化チタン多孔質膜と吸着色素(ビピリジンルテニウム錯体,いわゆるN3色素など),ヨウ素レドックス系の有機媒体溶液を閉じ込めたナノヘテロ構造固体高分子(多糖類)からなる色素増感光化学電池を構築し,光電変換特性を研究した.これらの過程で,ヨウ素レドックス系による電荷輸送は固体系ではやや遅いが,条件によっては液体系と同等になることがかった.次に,電導性電極基盤として電導性プラスチックフィルム(ポリエチレンナフタレート,PEN)を用いた有機薄膜光化学電池を構築した.光電変換効率は1%カラゲニン固体電解質膜を用いた時に,照射擬似太陽光(AM1.5,100mWcm^<-2>)あたり1.5%であった.ガラス基板電極(FTO)を用いて作製した通常のDSSCと全プラステイックDSSCのI-V特性を比較した.後者で低い変換効率の理由を解明するため,交流インピーダンス法で各電荷移動段階の抵抗を解析,比較した.通常のDSSCに比べて,プラステイック型ではRo(系全体のオーミック抵抗)の増加が最も大きい.電荷移動はお互いが関連するダイナミックな平衡系なので,Roに影響されて,他の抵抗も大きくなったと考えられる.これらの結果から,電導性プラステイック基盤の電導性を,二酸化チタン薄膜焼結後も高く保てれば,通常のガラス基盤型DSSCと同等の変換効率を持つ全プラステイック型DSSCを作製可能なことが明らかにできた.

When the liquid contains a large amount of maleic acid, the solid of the polysaccharides, the molecules disperse and light excite the state electrons, and the electrons enter the cathode interface to generate the charge shifts, and the molecules in the liquid start the same temperature. The color of solid materials is too sensitive to DSSC, the solid system is too sensitive to pigment, the whole system is too sensitive to pigment, the temperature is too high, the temperature is low, the temperature is too high, the temperature of the solution is too high, the temperature of the solid solution is too high, the temperature of the solid solution is too high, the temperature of the solid system is too high, the temperature of the solid system is too high, the temperature of the solid solution is too high, the temperature of the solid solution is too high, and the color of the solid system is too high. The dicarboxylic acid porous membrane absorbs the pigment (the wrong body, the N3 pigment), and the local media solution is used to produce solid polymers (polysaccharides), pigments, photosensitive chemical cells, photosensitive chemical cells, and photosensitive properties. During the whole process, it is necessary to transfer electricity to the fixed system, and the condition is the same as that of the liquid system. In the second stage, the electrical cathode is responsible for the use of the organic thin film photochemical cell (PEN) in the field of electrical engineering. The optical emission rate is 1%. The solid-state electrolysis film is used in the temperature range, and the temperature is 1.5% in the temperature range of exposure to phosphorescent light (AM1.5100mWcm ^ & lt;-2>). The substrate cathode (FTO) is used as a device. Usually, the whole DSSC system is used to compare the characteristics of the DSSC. The reason for the latter is to explain the situation and communicate the analysis of the resistance of each load transfer section of the load transfer program. Usually, "DSSC" is better than "Ro", and the most important thing is to increase the number of people who resist. The electric charge transfer is very important. The balance system is very important. Ro has a negative effect on the balance system, and it is very important for you to make sure that you don't have any problems. According to the results of the experiment, the electrical and mechanical properties are based on the basic electrical properties, and the dicarboxylic acid thin film is used to protect the high temperature after the operation. In general, the basic DSSC has the same operating rate as that of the full-range thermal DSSC.
