Abstract

CdSe semiconductors that have a direct band gap and high absorption coefficient are quite suitable materials for photovoltaic devices. The production of semiconductors with a cheap and simple method is very important in terms of cost reduction. This paper consists fabrication of CdSe thin film with electrodeposition which cheap and simple method. The electrodeposition was carried out in an aqueous solution consisting low concentration of CdCI2 and TeO2 at room temperature on indium tin oxide coated glass substrate (ITO) with a 1 mA/cm2 current density. The characterization of CdSe semiconductors thin film was made by UV-visible spectrophotometer, XRD (X-ray Diffraction), Raman spectroscopy, SEM (Scanning Electron Microscopy), EDX (Energy Dispersive X-ray Spectroscopy) and Hall-effect measurement. The CdSe thin film was found to have a hexagonal structure and a 1.71 eV energy band gap. The CdSe film has a chemical composition of 55 % Cd and 45 % Se. The carrier concentration of n-type CdSe film was measured as 8.80 x 1017 cm-3.
