本研究的目的是应用先进的微结构表征技术，研究不同的氯化镉退火温度对碲化镉太阳能电池的微结构沉积的近距离升华（CSS）的影响，并与此相关的电池性能。一系列的技术已被用来观察微观结构的形态变化以及作为处理参数的函数的化学和晶体学变化。还进行了将器件性能与电池的微观结构特性联系起来的电气测试。所使用的技术包括透射电子显微镜（TEM）的亚晶粒分析，X射线光电子能谱（XPS）的深度分布，以显示氯扩散到CdTe的温度的影响。利用电子背散射衍射（EBSD）在聚焦离子束（FIB）制备的平面截面上获得了晶粒取向数据以及晶粒尺寸变化。
The aim of this investigation is to apply advanced microstructural characterization techniques to study the effects of varying the cadmium chloride annealing temperature on the microstructure of cadmium telluride solar cells deposited by close spaced sublimation (CSS) and relate this to cell performance. A range of techniques have been used to observe the morphological changes to the microstructure as well as the chemical and crystallographic changes as a function of treatment parameters. Electrical tests that link the device performance with the microstructural properties of the cells have also been undertaken. Techniques used include Transmission Electron Microscopy (TEM) for sub-grain analysis, X-ray Photoelectron Spectroscopy (XPS) depth profiles to show the effect of temperature on the diffusion of chlorine into the CdTe. Grain orientation data as well as grain size change has been obtained using Electron Backscatter Diffraction (EBSD) on Focused Ion Beam (FIB) prepared planar sections.
