Rapid Formation of Ternary CdZnSe₂ Chalcogenide Thin Film by Microwave Assisted Chemical Bath Deposition

Abstract

Summary Nanostructured ternary cadmium zinc selenide (CZS) thin films have been deposited by a rapid and reliable Microwave assisted chemical bath deposition (MA‐CBD) method by using ethylenediaminetetraacetic acid (EDTA) and triethanolamine (TEA) as complexing agents. Optical, structural, morphological, compositional and electrical properties of CZS thin films have been investigated as a function of different complexing agents. Band gap energy of CZS thin films obtained for EDTA and TEA was 2.03 and 1.75 eV respectively. X‐ray diffraction (XRD) studies revealed that films were nanocrystalline in nature with mixed phase structure, in which cubic phase of CdSe dominant over hexagonal ZnSe. The scanning electron microscopy (SEM) images show porous surface morphology with distinct grains over the substrate surface. The EDS spectra show presence of Cd, Zn and Se elements. Thermoelectric power (TEP) measurement shows films were n‐type semiconducting in nature. Synthesized thin films shows potential for solar cell application.

The chemical process for materials deposition in aqueous solution: a review

“…Such modifications intend to improve and/or better control specific parameters and reactions to promote enhanced conditions for the resulting thin films. Different strategies such as microwaves [51][52][53][54][55][56][57][58][59][60][61][62][63][64], hydrothermal [65,66], light [67,68], seed-layer [69,70], ultrasonic wave [71], and surfactants [72] have been reported as additional/ alternative conditions for the CBD. Some advantages that such strategies have offered are time reduction [51,54,60], energy saving [64,67] and enhanced physical properties for the further applications [66,69,72].…”
