| 中文摘要 | 此論文主要概念性提出功能性高分子複合材料,個別應用於多種有機光電元件(包含太陽能電池、發光二極體以及光偵測器)。在原本廣泛使用於高分子太陽能電池系統中主動層系統(半導體高分子及碳六十衍生物)額外加入功能性材料,第一部分以材料之間自然垂直相分離特性進行介面修飾以得到穩定及高效率有機太陽能電池,並且此方式進而延伸實現於提升高分子白光、藍光以及紅光發光二極體的發光效率。第二部分主要是以改變主動層內部能階,摻雜進近紅外光染料以引入一個功能性電荷載子捕捉點在主動層內,所引發光電倍增效應,因此光偵測器整體的光敏感度大大提升,並且在光學上有助於搭配原本系統(P3HT:PCBM)的吸收光譜,整體可以實現低操作電壓、高光感度以及寬譜反應的有機光偵測器。 |
| 英文摘要 | This dissertation essentially proposed a series of functional polymer blends for variousopto-electronical applications, aiming for interfacial modification and device engineering. Thefirst part of this dissertation is to conceptually introduce a simple approach to realizenano-scaled interfacial modification for stable and efficient organic photovoltaic devices(OPVs). Through spontaneous vertical-phase-separation, a self-assembled poly(ethylene glycol)(PEG) buffer layer can be formed on the top-surface of the active layer, thereby naturallyacting as a cathode buffer layer. Moreover, not only for OPVs devices, this approach can alsobe employed to fabricate high-performance sky-blue, red and white polymer light-emittingdiodes (PLEDs). Secondly, we also proposed other functional polymer blends incorporating different types of energy-level structures for resulting in distinct optoelectronics phenomenon.We have found that introducing functional trapping sites inside the bulk by dopingnear-infrared (NIR) dyes can lead to completely different electrical characteristics featuringorganic photodetectors. As a result, high external quantum efficiencies (>7000%), highresponsivities (32.4 A/W) and broadband response (300 nm to 1050 nm) has been achievedsimtaneously at an extremely low operating voltage (-1.5 V). |
