Solar Energy Materials Synthesis and Characterization

Abstract

The studies on the structural, microstructure and composition of the MoSe₂ films are discussed in this research work. It deals with the optical properties of pulse plated films of MoSe₂. Very little information has been given in the literature concerning the deposition current efficiency using pulse plating. In agreement with pulse plating theory, according to reference, the limiting overall plating rate of materials generally does not exceed the values for DC plating conditions. The pulse current density influences the concentration, but not the deposition mechanism. This is possible however if two or more competing reactions take place in the deposition process e.g., the metal ion discharge and hydrogen evolution. As both reactions show different kinetics and current efficiency values, it can be possible to exceed the DC plating rate using suitable pulse plating parameters.
