摘要

太陽能電池在綠能產業有很大的進步空間，且對環境無害。而Miyasaka教授以及其同事於2009年首次將鈣鈦礦引入作為光伏應用的動態材料。從2009年以來，鈣鈦礦太陽能電池的光伏性能獲得大幅提升，從3.9%上升至近年的22.1%，至今據報導已經到了25.2%，提供了再生能源新的路徑。然而低成本又高效能的電洞傳輸層材料相當稀少。所以要將鈣鈦礦太陽能電池商業化仍是一項艱難的任務，因此非常需要開發新一代的電洞傳輸層材料。
在第 1 章和第 2 章中，簡要討論了鈣鈦礦太陽能電池，以及本文中使用的電洞傳輸材料和表徵方法。 第三章合成了兩個以芳胺為供體基團，以二噻吩並噻吩和二苯並噻吩為π橋的D-π-D型化合物。 系統地研究了光吸收、能階、熱性能及其在鈣鈦礦太陽能電池中的性能。
第四章合成了四種以芳胺和咔唑為供體基團，二噻吩並噻吩和二噻吩並吡咯為π橋的D-π-D型化合物。 系統地研究了光吸收、能級、熱性能及其在鈣鈦礦太陽能電池中的性能。
第五章以苯並二噻吩為中心核，芳胺為供體基團，合成了四種新的二取代化合物。在鈣鈦礦太陽能電池中，這些電洞傳輸材料用光吸收、能級、熱特性和光伏性能來描述。在第六章中，合成了四種以芳胺為供體基團、二噻吩並吡啶-5(4H)-one為π-橋的D-π-D型化合物。對電化學和光學性能、熱性能進行了研究。在第七章，結論和展望。

Abstract

A future based on green energy inspires the development of new advancements and is harmless to the ecosystem, such as solar-powered batteries and cells. Perovskites were first introduced as dynamic materials for photovoltaic applications by Miyasaka and colleagues in 2009. Photovoltaic performance of perovskite solar cells (PSCs) has improved dramatically, from 3.9% in 2009 to 22.1% in recent years, and a record of 25.2% has been reported, which offers a new route for harnessing renewable energy.
PSC industrialization, however, is still a challenging task due to the scarcity of low-cost and high-performance organic hole-transport materials (HTMs). It is therefore highly desirable to develop new generations of HTMs. To develop novel, inexpensive, and easily synthesized organic HTMs for efficient PSCs, the goals of this thesis are to develop novel organic HTMs that are cheap and readily synthesized. To further increase the stability and lower the price, a number of HTMs made from organic small molecules were designed, created, and tested for their photovoltaic performance.
In Chapter 1 and Chapter 2, Perovskites solar cells are briefly discussed, along with Hole-transport materials and the characterization methods used in this thesis.
In Chapter 3, two D-π-D type compounds with arylamine as the donor groups and dithienothiophene, and dibenzosepithiophene as a π-bridge were synthesized. Light absorption, energy level, thermal properties, and their performance in perovskite solar cells were all systematically explored.
In Chapter 4, four D-π-D type compounds with arylamine and carbazole as the donor groups and dithienothiophene, and dithienopyrrole as a π-bridge were synthesized. Light absorption, energy level, thermal properties, and their performance in perovskite solar cells were all systematically explored.
In Chapter 5, Benzodithiophene as the central core and arylamine as donor groups were used to synthesize four new di-substituted compounds. In PSCs, these HTMs are described by light absorption, energy level, thermal properties, and photovoltaic performance.
In Chapter 6, Four D-π-D type compounds with arylamine as the donor groups and dithienopyridin-5(4H)-one as the π-bridge was created. In-depth studies were conducted on the electrochemical and optical properties, thermal properties, and PSC performance.
In Chapter 7, Conclusions and Outlook.
Keywords: Perovskite solar cells, photovoltaic devices, hole transporting materials, dithienothiophene, dithienopyrrole, dibenzothiophene, dithiophenepyridin-5(4H)-One, arylamine, Carbazole.
