摘要

透明電極是光電產品中極重要的材料，除了可見光波段的高穿透率與高導電度特性外，對於有機發光二極體與太陽能電池這類元件尚需考量能階匹配。因此，能階分析對於透明電極材料的開發是相當重要的一個關鍵。本文回顧目前透明電極主要的分類，並說明光電子能譜激發術分析技術原理與如何應用於材料表面分析。

Transparent conducting films are an important class of materials for optoelectronics. Other than the transmission in the wavelength of visible light and the conductivity, the energy band alignments of transparent conducting films to other materials in the optoelectronic devices, such as solar cells, are also keys to the performance of the devices. Therefore, the analysis of the energy levels of these materials is crucial in the development of these materials. In this article, we will review the materials for the transparent conducting films and the principles of photoemission spectroscopy. The application of photoemission spectroscopy to energy band alignment measurement and the surface analysis will also be discussed.
