Abstract
ABSTRACT This work is focused on the optimization and characterization of copper gallium sulfide (CuGaS2) thin film prepared via the spray pyrolysis route. Chalcogenides are compounds having a chalcogen anion and an electropositive element, and these thin films have more absorption coefficients. The structural, optical, electrical, and morphological properties of CuGaS2 thin films are studied using X-ray diffraction (XRD), Scanning electron microscopy (SEM), UV-Vis-NIR Spectroscopy, and Hall effect techniques. The above characteristics are studied for both as prepared and annealed Copper Gallium Sulfide (CGS) thin films. These films have a chalcopyrite tetragonal crystal structure. It is a promising material for solar cell applications due to its suitable bandgap and good electrical stability. The results of this study provide a framework for fabricating an optimized CGS absorber layer in photovoltaic solar cells. GRAPHICAL ABSTRACT Schematic diagram of preparation of CGS thin films by Spray Pyrolysis Technique.
期刊介绍：
Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include:
-structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.)
-geophysical phase transitions
-metal-insulator phase transitions
-superconducting and superfluid transitions
-magnetic phase transitions
-critical phenomena and physical properties at phase transitions
-liquid crystals
-technological applications of phase transitions
-quantum phase transitions
Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
