在本篇論文中，我們使用全有機系統作為有機上轉換元件之材料，並結合有機太陽能電池(Organic photovoltaic, OPV)、有機光偵測器(Organic photodetector, OPD)與有機電激發光二極體(Organic light emitting diode, OLED)之三者特性設計成有機上轉換元件，主要使不可見近紅外光(NIR)經由元件內部光→電→光之轉換為綠色可見光之波段，本篇論文使用單層酞菁氯化鋁 (Chloroaluminum phthalocyanine, ClAlPc)同時作為有機上轉換元件載子產生層以及暗電流電洞阻擋層，並以有機光偵測器之結構分析其特性，最終結合高效率有機磷光錯體發光二極體做為發光單元，並且比較本實驗室歷年上轉換元件的差異。
首先利用OPV結構驗證其使用單層ClAlPc之結構於780 nm光源照射下擁有單層載子拆解的特性，再完整分析以ClAlPc作為載子產生層(Charge generation layer, CGL)順偏壓驅動的有機光偵測器結構，最終結合有機磷光錯體發光二極體使載子產生層作為上轉換元件之電洞供應端，透過量測計算其擁有18.97% (p/p)上轉換效率以及1702 cd/m2之高亮度於照射NIR LED 5 mW/cm2強度下，且電流增益可高達70萬倍。

In this paper, we used all-organic system as the material of upconversion devices. The characteristics of upconversion device designs are combined with organic photovoltaic (OPV); organic photodetector (OPD) and organic light emitting diode (OLED). The devices mainly covert invisible near-infrared into the wavelength of visible green light through the internal photoelectric conversion. In this article, we make a single layer of Chloroaluminum Phthalocyanine used as the charge generation layer and the hole blocking layer of the organic upconversion device, and also completely analyzed the characteristics of organic photodetector.
First of all, the OPV structure was used to verify that the single layer of ClAlPc has the ability of exciton dissociation. Secondly, we completely analyze the characteristics of ClAlPc as charge generation layer and hole blocking layer OPD model under forward bias voltage. At last, we combined OPD with high current gain and phosphorescent exciplex OLED with high EQE in the upconversion device. It shows 18.97% of upconversion efficiency and 1702 cd/m2 of high luminance when it is irradiated by 5 mW/cm2 NIR LED.
