| dc.description.abstract | 本論文有三個主題,第一部分為小分子太陽能元件之研究,第二部分為三重態-三重態-湮滅藍色有機發光二極體,第三部分為有機發光二極體光萃取之研究。
第三章中,我們利用結構為施體-受體-受體型小分子電子施體材料和碳70電子受體材料作為太陽能元件之主動層於塊材異質混和界面架構下,藉由主動層濃度及厚度的變化,進行四個小分子材料7-(4-(di-p-tolylamino)phenyl)-6-fluorobenzo[c][1,2,5]thiadiazole-4,5-dicarbonitrile (DTCPiFBTCN), 7-(4-(di-p-tolylamino)phenyl)benzo[c][1,2,5]thiadiazole-4,5-dicarbonitrile (DTCPBTCN2), 7-(4-(di-p-tolylamino)phenyl)benzo[c][1,2,5]thiadiazole-4,5,6-tricarbonitrile (DTCPBTCN¬3) 及7-(5-(di-p-tolylamino)thiophen-2-yl)benzo[c][1,2,5]thiadiazole-4,5,6-tricarbonitrile (DTCTBTCN3¬) 的比較,DTCPBTCN2作為電子受體之太陽能元件有著最佳功率轉化為5.41%,其開路電壓、短路電流密度和填充因子分別為0.89 V、10.81 mA /cm2 及56.26%。 在第四章中,我們使用兩個新的蒽核衍生物材料1-phenyl-2-(10-phenylanthracen-9-yl)-1H-benzo[d]imidazole (monoBizAn) 及 4,4,5,5-tetramethyl-2-(10-(naphthalene-2-yl)-1,3,2-dioxaborolane (NpBorAn) 作為三重態-三重態-湮滅藍色有機發光二極體之發光體,以純膜及客體材料高濃度混入9,9'-(2-(1-Phenyl-1H-benzo[d]imidazol-2-yl)-1,3-phenylene)bis(9H-carbazole) (o-DiCbzBz) 製作藍色有機發光二極體,元件以monoBizAn作為客體材料濃度60%混入o-DiCbzBz中有著最佳元件表現,在電流效率、功率效率及外部量子效率方面達到5.74 cd /A、4.71 lm/W 和5.56%。 在第五章中,使用三種不同週期的光柵 (833.33, 416.67, 277.78奈米)來製作藍色磷光有機發光二極體元件,藉由氧化銦鋅進行氧電漿時間、陽極厚度及元件電洞傳輸層厚度之優化,週期為416.67奈米的光柵作為內部結構且搭配半球透鏡作外部結構製作元件,最高可以得到52.51%的外部量子效率以及82.52%的外部量子效率提升,並且利用偏振片的量測進行表面電漿態與波導模態的光萃取分析。 | zh_TW |
| dc.description.abstract | There are three parts in this thesis. First, we study on the small molecule solar cell. Second, we do the research about the triplet-triplet annihilation blue organic light-emitting diode. Last, we discuss light extraction through nanostructure in organic light-emitting diode.
In chapter 3, we compared four electron donor-acceptor-acceptor (D-A-A) type electron donor materials, 7-(4-(di-p-tolylamino)phenyl)-6-fluorobenzo[c][1,2,5]thiadiazole-4,5-dicarbonitrile (DTCPiFBTCN), 7-(4-(di-p-tolylamino)phenyl)benzo[c][1,2,5]thiadiazole-4,5-dicarbonitrile (DTCPBTCN2), 7-(4-(di-p-tolylamino)phenyl)benzo[c][1,2,5]thiadiazole-4,5,6-tricarbonitrile (DTCPBTCN¬3) and 7-(5-(di-p-tolylamino)thiophen-2-yl)benzo[c][1,2,5]thiadiazole-4,5,6-tricarbonitrile (DTCTBTCN3¬)¬, with fullerene-based material C70 as the electron acceptor material in the active layer of small organic solar cells (SMOSCs) with bulk-heterojunction (BHJ) configuration. Among these D-A-A materials, DTCPBTCN2 as electron donor material with C70 as the electron acceptor material at the mixing ratio D:A=1:1.4 and 60 nm of active layer showed the highest power conversion efficiency of 5.41%, with open circuit voltage (Voc), short circuit current density (J¬sc) and fill factor (FF) of 0.89 V, 10.81 mA/cm2, and 56.26%, respectively. In chapter 4, we employed two new anthracene-core derivatives, 1-phenyl-2-(10-phenylanthracen-9-yl)-1H-benzo[d]imidazole (monoBizAn) and 4,4,5,5-tetramethyl-2-(10-(naphthalene-2-yl)-1,3,2-dioxaborolane (NpBorAn) as the blue triplet-triplet annihilation (TTA) emitters in the OLEDs with non-doped configuration and high doping concentrations in the host, 9,9'-(2-(1-Phenyl-1H-benzo[d]imidazol-2-yl)-1,3-phenylene)bis(9H-carbazole) (o-DiCbzBz). Device efficiency of TTA OLED with monoBizAn doped in o-DiCbzBz at 60% concentration showed the highest efficiency which achieved 5.74 cd/A, 4.71 lm/W and 5.56% in terms of current efficiency, power efficiency and EQE, respectively. In chapter 5, we studied the light extraction of blue phosphorescent organic light emitting diodes (PHOLEDs) with nanostructure (pitch = 833.33, 416.67, and 277.78 nm) between the substrate and the indium-zinc-oxide (IZO) anode. After optimizing plasma time、thickness of IZO and thickness of hole transport layer (HTL), blue PHOLED with nanostructure and macrolens can reach EQE value of 52.52% and enhancement ratio of 82.52%. Besides, we separate surface plasmon (SP) mode and waveguide mode to understand light extraction mechanism. | en |
