Abstract
- Copper antimony sulfide (CuSbS<subscript>2</subscript>-CSC) is a ternary layered semiconductor material that has been considered an absorber material in thin film solar cells due to its optimal band gap (~1.5 eV) with a high absorption coefficient of over (>10<superscript>4</superscript> cm<superscript>−1</superscript>). It has attractive optical and electrical properties, as well as earth-abundant, low-cost, and low-toxic constituent elements. The CSC material was prepared by simple ball milling with Sb<subscript>2</subscript>S<subscript>3</subscript> and two copper sources: copper acetate and copper chloride. The ground material was placed in the furnace for thermolysis. The temperature was set to 200°C for 1 h for all the samples. In addition, the influence of copper concentration was also analyzed. The prepared material was characterized by X-ray diffraction (XRD), Raman spectroscopy, selected area diffraction (SAED), and transmission electron microscopy (TEM). The XRD patterns confirmed the presence of the CuSbS<subscript>2</subscript> phase in most samples. Some samples show the temperature-dependent phases of CuSbS<subscript>2,</subscript> such as Sb<subscript>2</subscript>S<subscript>3</subscript> and Cu<subscript>12</subscript>Sb<subscript>4</subscript>S<subscript>13</subscript>. Raman and selected area diffraction (SAED) results were also in accordance with the XRD results. TEM shows the nanosized structure formation of the material. [ABSTRACT FROM AUTHOR]
