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.
