Abstract
CdS nanoparticles were synthesized for the application in direct write technology. Various parameters such as deposition time, pH, and cadmium ion concentration, were varied in order to observe optimum conditions for the synthesis of CdS nanoparticles. As a result of this study, it was confirmed that the optimum conditions for synthesis of CdS nanoparticles were pH 11, 70 °C, and 3 mmol/dm3 cadmium. CdS nanoparticles, synthesized under these conditions, were under-filled between two glass substrates, and the elements, cadmium and sulphur, on glass substrates were observed with an energy-dispersive X-ray spectrometer (EDX). This indicates that the deposition of CdS nanoparticles by a direct printing process into two substrates is possible, and CdS nanoparticles can be applied to the fabrication of a Cu(In,Ga)Se2/CdTe thin-film solar cell.
