Abstract

In this work the synthesis of zinc mercury selenide thin films (Zn _1-xHg_xSe) by electrodeposition is carried out. The films were deposited onto conducting glass (SnO₂) substrates from an aqueous solution bath containing ZnSO₄, HgCl₂ and SeO ₂ at bath temperatures between 30 °C and 70 °C. The influence of deposition parameters such as electrolyte composition, deposition potential and temperature on the crystallinity and composition of the films is studied. It is found that the amount of mercury content in the solution bath and deposition potential control the composition and structure of the alloy films. The films were characterized by x-ray diffraction (XRD), energy dispersive x-ray analysis (EDAX), optical absorption and scanning electron microscope (SEM) studies. Photoelectrochemical solar cells studies using Zn_1- _xHg_xSe thin films showed improved performance for annealed and etched electrodes and the results are discussed.
