dc.description.abstract | 隨著傳統石化能源日益枯竭,尋找替代能源便成了當前相當熱門的議題,眾多替代能源中,又以鈣鈦礦太陽能電池的研究越發受到重視。鈣鈦礦太陽能電池是由多層材料堆疊而成,其中的電洞傳輸層 (hole-transporting material, HTM ) 負責電子與電洞的拆解,在元件中扮演關鍵的角色。
綜觀電洞傳輸材料的製備方法大多以傳統多步驟人名反應為主,此方法具有合成步驟繁瑣、需要使用對環境危害之有機金屬試劑以及成本昂貴等缺點。本研究團隊曾發表以鈀催化劑直接碳氫鍵芳香環化反應,來製備電洞傳輸材料,此方法順利解決了上述前兩項缺點,然而鈀催化劑的售價仍然偏高。因此,本文嘗試以低成本的銅催化劑直接碳氫鍵芳香環化反應,來進行電洞傳輸材料的合成。
近年來,以并三噻吩為核心結構的有機小分子,被廣泛地應用於有機光電材料中,然而其在鈣鈦礦太陽能電池的應用卻極為少見,且僅有推電子基團–π共軛核心–推電子基團 (electron donor –π linker –electron donor, D–π–D) 及推電子基團–π共軛核心–拉電子基團 (electron donor –π linker –electron acceptor, D–π–A) 兩種型式。因此本研究除了製備以并三噻吩為主的D–π–D型電洞傳輸材料外,亦嘗試開發以并三噻吩為核心結構之拉電子基團–π共軛核心–拉電子基團 (electron acceptor –π linker –electron acceptor, A–π–A) 型式的有機小分子光電材料。
首先,我們以低成本的銅催化劑直接碳氫鍵芳香環化反應,合成出TTh101,並透過更換不同的反應溶劑、銅催化劑、鹼以及配位基等,來篩選出此反應的最佳化條件。接著嘗試以銅催化劑直接碳氫鍵芳香環化反應合成出CHC05-07及CHT01-03,最後對此七種小分子進行熱性質及光電化學性質的分析與探討,以及實際應用於鈣鈦礦太陽能電池的表現。 | zh_TW |
dc.description.abstract | Recently, the research of perovskite solar cell (PSC) is getting more critical in the field of organic photovoltaic materials. Moreover, the hole-transporting material (HTM) plays an important role in PSCs.
Various novel HTMs have been prepared by Suzuki–Miyaura and Stille cross-coupling reactions. These traditional synthesis routes have some disadvantages, such as tedious synthetic steps, high-cost and using of toxic organometallic reagents. Our team have already developed a new synthesis of HTMs via palladium-catalyzed direct C-H arylation. However, the cost was still high. In this research, we developed a lower-cost synthesis of dithienothiophene(DTT)–based D–π–D and D–π–A type HTMs by copper-catalyzed direct C-H arylations.
In this research, we screened the different kinds of reaction solvents, copper catalysts, bases and ligands to optimize the reaction conditions of the copper-catalyzed direct C-H arylation, then to synthesize TTh101, CHC05-07 and CHT01-03 by optimized conditions. Finally, we investigated their thermal properties, photovoltaic characteristics and its performance on PSCs. | en_US |
