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.

温度对硫化铜镓（CuGaS2）薄膜光电性能的影响

摘要本工作的重点是通过喷雾热解法制备硫化铜镓（CuGaS2）薄膜的优化和表征。硫族化合物是具有硫族阴离子和正电元素的化合物，并且这些薄膜具有更多的吸收系数。利用X射线衍射（XRD）、扫描电子显微镜（SEM）、紫外-可见-近红外光谱和霍尔效应技术研究了CuGaS2薄膜的结构、光学、电学和形态特性。对于所制备的和退火的铜镓硫化物（CGS）薄膜都研究了上述特性。这些薄膜具有黄铜矿四方晶体结构。由于其合适的带隙和良好的电稳定性，它是一种很有前途的太阳能电池材料。本研究的结果为在光伏太阳能电池中制备优化的CGS吸收层提供了框架。用喷雾热解技术制备CGS薄膜的示意图。

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.
