Abstract:	近幾年來，有機材料的太陽能電池 (如 DSSCs, OPVs 及 PSCs) 其發展受到高度重視，其中又以鈣鈦礦太陽能電池備受青睞，在 2010 至 2022 年間，光電轉效率由 3.9% 提升至 25.7%，展現出強大的潛力。先前實驗室發表的論文中以 benzimidazole 作為核心，設計出非對稱的電洞傳輸層材料其元件效率高達 20.81%，所以本篇以 benzimidazole 作為核心設計出對稱型分子在中心分子的鄰位和間位接上兩個 triphenylamine 作為 donor，合成出 IZO 和 IZM，接著我們利用 benzene 連接兩個 benzimidazole 延伸核心的 π-conjugation，並分別在 benzimidazole 的鄰位和間位接上四個 triphenylamine 作為 donor，合成出 BZO 和 BZM。此系列化合物與鈣鈦礦層有匹配的能階，並擁有良好的熱穩定性及優異的溶解度，除了這些優勢之外，benzimidazole 上的氮原子可以與鈣鈦礦層的離子產生作用力彌補鈣鈦礦層缺陷，使晶體生成更順利且平整，能夠有利於電荷的傳遞，進而提升元件的效率表現，預期本研究之 BZO, BZM, IZO 和 IZM 的光電轉換效率將優於標準品 PEDOT:PSS。;In recent years, the development of organic materials of solar cells has been highly valued, including DSSCs, OPVs, PSCs. The photoelectric conversion efficiency of perovskite solar cells has increased from 3.9% to 25.7%. In the previous paper published by our laboratory, YJS003 are asymmetric structure with benzimidazole as the core. Using YJS003 as a dopant-free HTM in a p-i-n PSCs device structure achieved a PCE of 20.81%. Therefore, in this study, we designed symmetrical structures with benzimidazole as the core, and two triphenylamines were connected on the ortho and meta position to synthesize IZO and IZM. Then we connect the two benzimidazoles with benzene, extending the π-conjugation of the core, and connect four triphenylamines on the ortho and meta positions to synthesize BZO and BZM. This series of compounds have suitable energy levels, excellent thermal stability and solubility. In addition to these advantages, the benzimidazole backbone can passivate the defects or stabilize the halides in the perovskite through hydrogen-bonding interaction. Passivation can facilitate the transfer of charges, thereby improving the efficiency of the device. It is expected that the photoelectric conversion efficiency of BZO, BZM, IZO and IZM will be better than of PEDOT:PSS.
