博士 === 國立臺灣科技大學 === 電子工程系 === 103 === In this article, the working principle and efficiency-theory of organic upconverter are investigated in detail. Based on the mechanism of conductive-carriers generation to control the process of photon-carrier-photon conversion, the upconverter utilizes a simple architecture through directly depositing the organic materials of organic light emitting diodes and organic photovoltaic in serious-connection. Anodic, cathodic, and tandem type upconverters will be demonstrated with different arrangements of charge generation layer and light-emitting components. Also, with embedded mirrors, an upconverter which possesses two individual units and ideal calculation of external quantum efficiency is assembled. Not only the high efficiency, but also the different wavelength-conversion will be demonstrated in novel structure development in line with certain innovative theories. Meanwhile, a new ideal of quasi-device, namely, photosensitive-charge-generation unit, is proposed to simplify the process enormously and exceptionally. The real image-conversion application will ultimately be displayed with excellent display properties.
