中文摘要 | 近年來染料敏化太陽能電池(Dye-Sensitized Solar Cell, DSSC)之研究備受重視,然而長時間日照下造成模組穩定性以及模組效率明顯衰退,這是染料敏化太陽能電池急需設法解決的問題。因此本研究提出一種再活化的方法,將老化的染料及電解液通過溶液清洗去除,保留原有的工作電極層,再次重新吸附染料以及注入電解液。本研究分別使用酸性、中性以及鹼性三種不同性質的溶液進行脫吸附,並且進一步利用紫外光/可見光光譜儀(UV/Vis૰ spectrometers)與電子顯微鏡測量試片以及太陽光模擬器進行效率的量測, 發現NaOH(aq)濃度5×10-3M的鹼性溶液不僅無毒性並擁有最佳的脫附效果,進行多次脫吸附實驗,效率從4.7%下降並穩定維持於4%,經過實驗研究證實再活化實驗可應用於染料敏化太陽能電池,延長其使用期限。 |
英文摘要 | The dye-sensitized solar cells (DSSCs) have attracted increasing interests in recent years. However, the reliability and efficiency of the DSSCs module in prolonged sunshine decline obviously. These problems of dye-sensitized solar cell need to be solved as soon as possible. In this work, we proposed a new activation-method to reuse the dye-sensitized solar cells, and long-term operation of re-activated DSSC module was also investigated. The used dye and electrolyte were replaced with the new dye and fresh electrolyte by desorption-treatment and e-adsorption of dye for the TiO2 layer. Different concentrations of acidic, neutral and alkaline solutions were employed to desorb the dye. The feasibility of the activation-method was examined by UV-Vis spectrometer, field emission scanning electron microscopy and solar simulator. In the summary, this study successfully provides a method for dye desorption/adsorption on TiO2 by using 5 × 10-3 M NaOH(aq) solutions. The NaOH(aq) desorption solution not only shows good desorption property but is also nontoxic. After three desorption cycles, the efficiency decreased from 4.7% and stably remained at 4%. Therefore, this research demonstrates the feasibility of re-using the photoelectrode after long-term operation of DSCCs modules. |
