Antimony compounds, particularly antimony trioxide (Sb2O3) and sodium antimonate (NaSbO3), are utilized as fining agents in the manufacturing of patterned solar glass to enhance light transmission. However, the composi�on of solar glass varies, par�cularly in terms of an�mony content, depending on the produc�on method. Newer modules increasingly use Sb-free or low-Sb float glass, which is easier to recycle and poses. Antimony (Sb) is a commonly used refining agent in solar glass. Solar Panel Stewardship will support material traceability and collection streams that will identify this "invisible" metal and support its safe recovery and availability for high-tech markets including reuse in new PV panels. Yet it sits on every major critical mineral list —from the European Union to the United States, Japan, and Australia—to yes, the CMI. because it. The proposed PhD thesis is part of the ANR GRISBI project (2026–2030), which aims to optimize the recycling of glass from photovoltaic (PV) panels.
