Abstract:	鈣鈦礦太陽能電池自2013到2025年間，效率從3.9%提升至27.0%，展現出這個領域的發展潛能；元件裡的每一層都至關重要，而本篇論文則以電洞傳輸材料為重。 Pz series 是以含氮雜環吡唑(Pyrazole)為中心，旨在希望經由含氮雜環的孤對電子對 (lone pair)鈣鈦礦層未配位的Pb2+進行配位，達到缺陷鈍化(passivation effect)的效果；並接有三苯胺(Triphenylamine)作為電子予體，電子受體則為苯環或吡啶(Pyridine)接上三氟甲基(Trifluoromethyl)所組成。而後經由光物理、電化學、熱穩定等一系列的相關儀器去作測試，並對結果進行探討，而元件效率則是由臺北科技大學蘇昭瑾教授團隊協助，期盼能達到本篇論文的預期目的。 Ac series 是以醯肼(Hydrazide)衍伸物醯腙(Acylhydrazone)和尿素(Urea)衍伸物甘脲 (Acetylenediurea)作為結構中心去做發想，由於有文獻表明肼基能與鈣鈦礦層未配位的 Pb2+形成化學鍵結，因此本篇以其關係物作為電洞傳輸材料，期望能與醯肼有一樣的好表現。此系列同樣經由光物理、電化學、熱穩定等一系列的相關儀器去作測試，並對結果進行探討。;Since 2013, the power conversion efficiency of perovskite solar cells has significantly improved from 3.9% to 27.0% by 2025, demonstrating the great potential of this field. Every layer in the device plays a crucial role, and this thesis focuses on the hole transport material (HTM) layer. The Pz series features nitrogen-containing heterocycle pyrazole as the central core, aiming to utilize the lone pair electrons of the nitrogen atoms to coordinate with uncoordinated Pb²⁺ in the perovskite layer, thus achieving a defect passivation effect. Triphenylamine was incorporated as the electron donor moiety, while the electron acceptors consist of either a phenyl or pyridine ring substituted with a trifluoromethyl group. This series was evaluated through photophysical, electrochemical, and thermal stability measurements, and the results were further analyzed. The device performance was assisted and characterized by Professor Chao Chin Su’s group at National Taipei University of Technology, with the goal of achieving the desire proposed in this work. The Ac series was inspired by acylhydrazone, a derivative of hydrazide, and acetylenediurea, a urea derivative, as core structures. Literature reports that hydrazine-based moieties can form chemical bonds with uncoordinated Pb²⁺ in perovskite layers. Therefore, related analogs were explored as HTMs, with the expectation of achieving similar beneficial effects. This series was also examined using various photophysical, electrochemical, and thermal stability techniques to evaluate and discuss their performance.
