제목 | Characteristics of Cadmium Telluride (CdTe) Films Synthezied by an Electrodeposition Method |
초록 | CdTe films are one of the most promising materials for low cost photovoltaic devices because CdTe materials have the efficient energy band gap (~1.45 eV at room temperature) and the high absorption coefficient (~5x105 cm-1) in the range of sunlight wavelength. In this study, CdTe films are synthesized by an electrochemical method. The CdSO4 and TeO2 are used as precursor materials in a deionized water mixed a sulfuric acid solvent and the pH of the solution keep from 1 to 2. The substrate, which is composed of CdS/ITO/glass, is located on the electrode and Pt is used as the anodic material. To improve grain size and stoichiometry, the CdTe films were annealed in a tube furnace at 400℃ for 2 h under flowingnitrogen. The morphological, structural and composition results of CdTe thin films obtained by ScanningElectron microscopy, X-ray diffractionwill be presented. The researchers involved in this work were supported by the 2nd phase of the BK21 program. |
