Abstract

In the present work, we report the electrochemical growth and characterization of CdTe semiconductor thin films in alkaline solution. The electrodeposition was performed cathodically applying a constant potential. Tellurium (IV) and Cd2+ aqueous alkaline solutions were employed as precursor of CdTe. EDTA was used as complexing agent for Cd2+ ions. The thin film composition was determined by atomic emission spectroscopy with inductive coupling plasm (AES-ICP) and Energy Dispersive X-ray Analysis). UV-visible spectroscopy allowed determining the optical band gap energy, which was 1.64 eV. The photovoltammetric experiment shows up that the synthesized CdTe thin film was p-type semiconductor.
