Lead-Free Semiconductors for Photovoltaic Applications

This research focuses on developing environmentally friendly semiconductor materials for solar cell applications. Two promising candidates, cesium antimony bromide and silver bismuth sulfide, were systematically investigated. Detailed thin-film characterization confirmed their structural stability and photovoltaic potential. By optimizing material synthesis and device fabrication methods, the study achieved better thin film quality and stronger ability to harvest sunlight without the use of toxic elements. Solar cell device testing further demonstrated improved efficiency, showing the practical promise of these materials. Overall, this research highlights safe, low-cost, and sustainable pathways for next-generation solar cells, supporting the transition to cleaner renewable energy technologies.
