Study of Transmittance of CdS Thin Films Prepared by Spray Pyrolysis
Cadmium chloride and thiourea were used as raw materials to synthesize precursor solution, and CdS thin films were prepared on glass substrates by the home-made spray pyrolysis thin-film preparation device.Affects of preparation parameters, for example, the substrate temperature and fog particle velocity on the structure of CdS thin films were emphatically studied in the paper. The results showed that the optimum conditions for preparation of CdS thin films are as follows: the substrate temperature 350 °C, the gas flow rate 4L/min, and the annealing temperature 400 °C. Under the optimum conditions and argon as the carrier gas, with a spray time of 32s, a 1.9um thickness CdS film which had a (002) plane grain size of 32.3nm was obtained. And the transmittance of the film was above 70% at the wavelength range of from 500nm to 850nm.
