Synthesis and characterization of Nanostructured Cobalt Sulphide doped with Dysprosium for photovoltaic application

Abstract

The technological world is in search of environmentally friendly methods of generating energy for the use of the ever growing needs of power for sustainable development of visually all facet of life. Solar energy form an environmentally friendly solution for the reduction of global warming. For usage in photovoltaic applications, this work explores the production and characterisation of nanostructured cobalt sulphide (CoS) doped with dysprosium (Dy), a rare earth element. In order to increase CoS's efficiency in solar energy conversion, rare earth doping is used to improve its optical, electrical, and structural characteristics. To maximize performance, precise Dy doping doses were used in the electrochemical synthesis of the nanomaterials. UV-visible spectroscopy were among the characterization methods used to examine the optical and structural characteristics of the doped CoS nanomaterials. Significant alterations in the bandgap and optical absorption behavior are shown by the results, indicating that Dy-Doped CoS nanostructures hold great promise for enhanced photovoltaic performance. This study opens the door for the use of Dy-doped CoS in renewable energy technologies by demonstrating their viability as prospective materials for next-generation solar cells.
