Abstract:	本研究針對實驗室所開發之釕錯合物錯合物染料 HBC-23 進行元件組裝條件優化，並使用紫質染料 YD-2 或本實驗室合成之染料BTI-7/POEt/JIA-SQ-1/DUY-1 做為共敏化劑，以提高所組裝電池的效率及穩定性。本研究也使用共吸附劑 CDCA 或後吸附劑 PVA、OPA、TMEA-TMOS、TEOS 等方法來組裝元件。結果顯示只以HBC-23 為敏化劑所組裝之元件的最高效率為 8.29%，與 HBC-23 搭配最良好的共敏化劑為 YD-2，以 HBC-23 為主敏化劑 YD-2 為共敏化劑所組裝之電池最高效率為 7.95%。電池之 IPCE 光譜顯示當主敏化劑為 HBC-23，共敏化劑為 YD-2 之電池在 650 nm ~ 700 nm 處之IPCE 值最高上升了約 15%，且主敏化劑為 HBC-23 共敏化劑為 YD2 所組裝之電池長時間穩定性較只以 HBC-23 為敏化劑所組裝之元件好。電池組裝完在大氣中之黑暗環境下置放 500 個小時後，有使用 YD-2 之電池仍維持 7.57%的效率(跌幅約 5%)，而同樣條件下使用單一 HBC-23 染料組裝之電池效率則下降了 13%，其原因為當使用共敏化時，光電極上之總染料吸附量由 2.12 × 10-8 mole cm-2 µm-1上升至 2.94 × 10-8 mole cm-2 µm-1，使電解液內造成效率下降之離子IO3-較難吸附於覆蓋率較好的二氧化鈦表面上。;In this study, we focused on optimizing the device assembly conditions for the ruthenium complex dye HBC-23, developed in our laboratory. We also employed the commercial porphyrins dye YD-2 or the dyes developed in our lab BTI-7/POEt/JIA-SQ-1 as co-sensitizers to improve the cell efficiency and stability of DSC. Futhermore, co-adsorbents CDCA or postadsorbents PVA, OPA, TMEA-TMOS, and TEOS were also tested. The highest efficiency of DSC based on only HBC-23 sensitizer is 8.29%.While the best-performing of HBC-23 co-sensitizer with YD-2 resulted in a maximum cell efficiency of 7.95%. The IPCE spectra of the cells revealed that the IPCE value at 650-700 nm increased by approximately 15% when HBC-23 was used as the main sensitizer and YD-2 as the co-sensitizer. The long-term stability test of the cells showed that when HBC-23 is the main sensitizer and YD-2 is the co-sensitizer, the cell maintained an efficiency of 7.57% (decreased by 5%) after being placed in a dark environment in the atmosphere for 500 hours. However, the efficiency of the cell assembled with HBC-23 dye decreased by 13% under the same conditions. The reason is that when using the co-sensitizer YD-2, the total dye adsorption on the photoelectrode increased from 2.12 × 10-8 mole cm-2 µm1 to 2.94 × 10-8 mole cm-2 µm-1 . The increase of dyes absorbed on TiO2 makes it more difficult for the IO3- molecules , which is in electrolyte and is harmful to the efficiency of the cell , to adsorb onto the better-covered titanium dioxide surface. As a result, the stability of the cell that use YD-2 as co-sensitizer is improved.
