“…Therefore, the intriguing physical properties of these type materials are need to be focused on. Although in literature, there were some reports about selenides and sulfides [4][5][6][7][8][9][10][11][12][13], up to now, the electronic nature and mechanical characteristic of CuGa5S8, which has a spinel-like structure and crystallizes in the face centered cubic with 𝐹4 ̅ 3𝑚 space group and 216 space number, have not yet been studied in detail. So, we focused on electronic behavior and some elasticity properties of the CuGa5S8 system by use of the ab initio simulation methods.…”

In this theoretical study, it is presented that the electronic behavior and mechanical characteristics of CuGa5S8 compound having face centered cubic structure with space group F4 ̅3m and space number 216. All calculations based on density functional theory (DFT) were performed by Generalized Gradient Approximation (GGA). It is understood from the observed electronic band structure of this system that it has semiconducting behavior close to zero-band gap. Also, the high similarity between spin-up and spin-down states indicates that the magnetic nature of this compound may be paramagnetic. Furthermore, the elastic constants were calculated by the stress-strain method, and then, the mechanical stability of this system was determined. Finally, these constants were used to predict some important mechanical properties of the mentioned system.

Cu(In,Ga)Se2 (CIGSe) thin films were prepared by sputtering with single CIGSe or Cu-Ga-In2Se3 target and subsequent selenization at 550-700°C. The one- and two-step selenization procedures and the ceramic and cermet targets were used for process comparisons. Microstructure, film growth and film composition were used to evaluate the growth performance. CIGSe films sputtered from the CIGSe target had a low Cu content. CIGSe films prepared with single Cu-Ga-In2Se3 target had shown different performance after the one- and two-step selenization procedures. The two-step process did not grow the dense films due to the vaporization of Se-containing species from the incomplete reaction. The high-temperature requirement is the major disadvantage for the post-selenization approach.

“…This feature offers not only a reduction of consumption of raw materials, but also leads to a wide variety of applications of thin film solar cells that take advantages of lightweight and flexible devices. Applications of flexible CIGS thin film solar cells include mobile use which has a strict weight requirement as well as for use as construction materials and car roofs by application to curved surfaces [11]. In addition to the properties of low weight and flexibility, the advantages of high efficiency and strong radiation hardness of flexible CIGS thin film solar cells are attractive.…”

In recent years, renewable energy technologies are being explored to meet the challenges of energy security and climate change. Solar energy is a clean and green renewable source of energy. It is an inevitable option to use photovoltaic effect to directly convert sunlight into electricity. CuIn 1-x Ga x Se 2 (CIGS) thin films were formed from an electrodeposited CuInSe 2 (CIS) precursor by thermal processing in vacuum in which the film stoichiometry was adjusted by adding In, Ga and Se. The structure, composition, morphology and opto-electronic properties of the as-deposited and selenized CIS precursors were characterized by various techniques. A 17.2% CIGS based thin film solar cell was developed using the electrodeposited and
