Resumen

Cadmium sulfide (CdS) thin films have been deposited by chemical bath deposition (CBD) at 70°C on glass substrates. In order to have a better control of deposition rate in CdS synthesis, Sodium borohydride and hydrazine were demonstrated as novel complexing agents. The structural, optical and electrical characteristics of the CdS thin films obtained were analyzed. Sodium borohydride as complex agent increased the deposition rate while hydrazine reduced the deposition rate due to higher complexation and slow generation of Cd²⁺ while improving the morphology of CdS films. Homogeneous CdS thin films with hexagonal crystalline structure and energy band gap of 2.4 eV were obtained. The deposited thin films showed a good electrical conductivity with resistivity values in the order of 10-300 Ω-cm, suggesting a low metal-semiconductor contact resistivity as well.
