Tungsten solar container materials

Researchers at Stanford University, in collaboration with the Belgian research center Imec, have developed a new manufacturing approach that enables the scalable production of semi-transparent and low-cost solar cells using tungsten instead of silicon. That dream is edging closer to reality thanks to groundbreaking research on copper indium gallium diselenide (CIGS) solar cells, enhanced by tungsten disulfide (WS2). Solar energy has become increasingly popular as the demand for cleaner and greener sources of power grows worldwide. This paper presents a novel broadband metamaterial perfect absorber (MPA), featuring a concentric ring cavity-based structure. The design utilizes a tungsten-alumina-graphite three-layer configuration, achieving over 90% absorption across 200–000 nm wavelengths, with peak absorption exceeding 99%.
