Abstract
Cadmium sulfide (CdS) continues to hold an important position among the solar cell materials and optoelectronic materials. It is usually used as window layer in the CdS/CdTe thin film solar cell. Indium doping of CdS increases its conductivity, which results in a lower series resistance of the solar cell. Optimizing the optical parameters of this material is important in getting high performance solar cells and in the use of the material in optoelectronic devices. In this work, polycrystalline indium doped cadmium sulfide (CdS:In) thin films were produced by the spray pyrolysis (SP) technique on glass substrates. Transmittance of the films was measured at room temperature in the wavelength range 400–1100 nm and used to deduce the optical parameters such as the absorption coefficient, extinction coefficient, refractive index, real and imaginary parts of the dielectric constant. The refractive index dispersion was analyzed by the single oscillator model and the oscillator parameters were computed.
