Investigation of Physical Properties of e-Beam Evaporated CdTe Thin Films for Photovoltaic Application
CdTe thin films with 2.8 µm thickness were deposited by electron beam evaporation method. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and atomic force microscopy (AFM) were used to characterize the films. The results of AFM analysis revealed that the CdTe films have uniform surface. CdTe thin films were heat-treated by SnCl2 solution. Structural analysis using XRD s...

Cu(In,Ga)Se2 thin films (CIGS) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of Co-evaporated metallic precursors in Se-containing environment under N2 gas flow. Structural properties of prepared thin film were studied. To characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...
متن کاملControlling Thin Film Surface Morphology for Improved Light Trapping
This work demonstrates the use of feedback control, coupled with a suitable actuator design, in manufacturing thin films whose surface morphology is characterized by a desired visible light reflectance/transmittance level. The problem is particularly important in the context of thin film manufacturing for thin film solar cells where it is desirable to produce thin films with precisely tailored ...
متن کاملInvestigations on structural and electrical properties of Cadmium Zinc Sulfide thin films
Nowadays, II – IV group semiconductor thin films have attracted considerable attention from the research community because of their wide range of application in the fabrication of solar cells and other opto-electronic devices. Cadmium zinc sulfide (Zn-CdS) thin films were grown by chemical bath deposition (CBD) technique. X-ray diffraction (XRD) is used to analyze the structure and crystallite ...
