| Abstract Scope |
Semiconductors with intermediate bandgaps have gained significant attention for enhancing photovoltaic efficiency and expanding optoelectronic applications. In this study, we investigate the structural and electronic properties of Cu₃VSₓSe4-x, a promising light-absorbing semiconductor. We systematically introduce selenium as a novel substituent to tune the optical bandgap of the material. Selenium substitution is demonstrated to enhance electrical conductivity, carrier mobility, and quantum efficiency in photovoltaic applications. To the best of our knowledge, this is the first report of the intermediate bandgap Cu3VSxSe4-x nanocrystals. The material was synthesized using a modified hot-injection reaction method and its crystallographic structure was confirmed through X-ray diffraction (XRD) analysis. Ultraviolet visible (UV-Vis) spectroscopy revealed an optimal intermediate bandgap, positioning this material as a strong candidate for efficient solar energy conversion. Further investigations into long-term stability under operational conditions and carrier transport dynamics will be crucial for practical implementation in next-generation solar cells and optoelectronic devices. |
