abstract

  • This paper presents the fabrication and characterization of CdS thin film solar cells synthesized by chemical bath deposition using acid as a complexing agent with pH values between 10.1 and 11.3. We studied the influence of pH control of the reaction solution on the structural and optical properties of chemically deposited CdS thin films. Different films thicknesses of CdS were deposited onto a glass substrate. The structural surface morphology of as-deposited CdS thin films was characterized by scanning electron microscope, x-ray diffraction, profilometer, and ultraviolet–visible spectroscopy. The investigation of the effect of the synthesis method on the change the ammonium hydroxide by buffer pH 11 contributed in increases the growth kinetics, resulting thicker films. The films show high absorption and band gap values were found from 2.38 to 2.58 eV with different time deposition. The results are quite appreciable and high efficiency can be obtained from these CdS thin-film solar cells. © 2016, Springer Science Business Media New York and ASM International.
