dc.description.abstract | 本論文研究主要分為有機光伏打電池(Organic Photovoltaic, OPVs)和鈣鈦礦電池(Perovskites Solar Cells, HTLs)材料之開發。
本研究主要延續之前開發出的雙噻吩併吡咯併噻吩 (DTPT)核心,再接上碳鏈 b-C20H41 以增加溶解度,之後外接五種不同拉電子單元,開發出 INF-DTPT-20 (1)、INBr-DTPT-20 (2)、DCV-DTPT-20 (3) 三種有機光伏打電池材料。此外,以DTPT為核心,外接Triarylamine-Functionalized Imidazolyl-Capped group 作為推電子基團,開發出DTPT-Im4D-20 (4) 應用於鈣鈦礦太陽能電池電洞傳輸層材料。另外,INF-DTPT-20 與DCV-DTPT-20正進行熱電性能的測試,未來可望成為有機熱電材料(Organic thermoelectric materials , OTMs)。
這些新材料的電化學及光學性能 (HOMO/LUMO 與 Eg) 已藉由 DPV 及 UV-Vis 測定,材料之熱穩定性已透過 TGA 及 DSC 檢測,這些新開發的有機光電材料正進行其相關之元件測試。 | zh_TW |
dc.description.abstract | A series of new organic optoelectronic materials were synthesized and characterized for applications in organic photovoltaic cells (OPVs), and perovskite solar cells (PSCs).
This study involves the development of a previously designed fused five-ring dithienopyrrolothiophene (DTPT) core and utilizing the longer alkyl chains (b-C20H41) to increase the solution processability. Wherein, the DTPT core was end-capped with various electron-withdrawing groups, such as dicyanomethylene indanone (IN), and its chloro- (INCl), bromo- (INBr), fluoro- (INF) derivatives and dicyanovinyl (DCV), via Knoevenagel condensation, yielding three new compounds, namely INF-DTPT-20 (1), INBr-DTPT-20 (2), and DCV-DTPT-20 (3) for OPVs or PSCs. In addition, DTPT was used as the core to develop DTPT-Im-4D (4) by attaching a Triarylamine-Functionalized Imidazolyl-Capped group as an electron-donating unit, which can be applied as a hole-transporting material for the PSCs. Furthermore, compounds 1 and 3 are under thermal conductivity testing and are expected to become organic thermoelectric materials (OTMs) in the future.
The optical and electrochemical properties of these newly developed compounds were characterized by UV-vis spectroscopy and DPV. Chemical structures were characterized by 1H NMR, 13C NMR, and mass spectrometry. Thermal properties were investigated by DSC and TGA. At present, optoelectronic devices based on these new organic semiconductors and non-fullerene acceptors are under optimization. | en_US |
