Abstract

The quest for sustainable and efficient energy sources has intensified the exploration of alternative materials and technologies for photovoltaics. As an emerging thin-film photovoltaic technology, chalcogenide solar cells are unanimously at the forefront of research and development due to their excellent light-absorbing capacity, low manufacturing cost, simple structure, and remarkable photovoltaic conversion efficiency. First, this paper reviews the significant progress made in the development of high-efficiency chalcogenide solar cells, including the development of material compositions, device structures, and fabrication techniques that have propelled PSCs to achieve efficiencies over 25%. The paper then highlights innovative approaches in interface engineering, tandem cell configurations, and manufacturing methods that have contributed to the high-efficiency results. While emphasizing efficiency gains, the paper outlines stability challenges, recognizing their role in the practical application of PSC technology. Finally, the paper outlines promising research avenues and technological breakthroughs that could further enhance the efficiency and application of PSCs in the global energy mix, giving them the potential for a wide range of applications in photovoltaic power generation.
