| dc.description.abstract | 近年來，鈣鈦礦太陽能電池備受矚目，於 2009 至 2020 年間，光電轉換效率從 3.9% 提升至 25.5%，而多數研究團隊都是以中性有機分子的電洞傳輸材料作為發表，離子型化合物較少被探討及研究，所以本篇以 pyrazine 為中心結構，外接四個 triphenylamine 合成出 pyrazinemethoxyltriphenylamine (PMO)，並將 PMO 中心的氮進行甲基化，合成出 PMO-CH3SO4，再與不同的飽和陰離子水溶液進行離子置換，分別形成最終分子 PMO-PF6, PMO-I 及 PMO-SCN。此系列化合物具有合適的highest occupied molecular orbital (HOMO)、熱穩定性及良好的溶解度，除了這些優勢之外，離子型分子可以彌補鈣鈦礦層缺陷，使晶體生成更順利且平整，進而更有利於電荷的傳遞，預期本研究之離子型化合物的光電轉換效率將優於 PMO 並運用於電洞傳輸材料。 | zh_TW |
| dc.description.abstract | In recent years, the photoelectric conversion efficiency (PCE) of perovskite solar cells has increased from 3.9% to 25.5%. Compared with ionic compounds, most research groups used neutral organic molecules as hole transport materials (HTM) for publication. Therefore, in this study, pyrazine was used as the central structure, and four triphenylamines were connected to synthesize PMO. After the central nitrogen of PMO was methylated, the compound PMO-CH3SO4 was synthesized, which was replaced with different saturated anion aqueous solutions to form PMO-PF6, PMO-I and PMO-SCN. This series of compounds has a suitable highest occupied molecular orbital (HOMO), thermal stability and good solubility. In addition to these advantages, ionic molecules can also compensate for the defects of the perovskite layer, making the formation of crystals smoother, which is more conducive to charge transfer. It is expected that the photoelectric conversion efficiency of the ionic compound in this study will be better than that of PMO, and it will be used as a hole transport material. | en_US |
