In PV glass, antimony is chemically embedded within the glass matrix, making its separation energy-intensive and technically challenging. In EEE products, antimony is typically used
The application of antimony as a clarifying agent in solar photovoltaic glass will become the main driving force for demand growth in the next decade.
However, glass manufacturers have been hard at work since then trying to eliminate antimony from solar glasses where it is considered necessary to use it. This article examines the breakthroughs recently
The production of this significant amount of (77.1–178 Mt) glass annually will place considerable pressure on raw materials, such as antimony (Sb), which is essential for PV glass
However, the composition of solar glass varies, especially concerning antimony (Sb) content, depending on the production method. Antimony is used to enhance the performance of
While float glass is most common in solar panels, patterned glass also contains antimony, a compound that improves solar glass efficiency but raises environmental and health concerns on the backend.
To make the recycling of PV glass into flat glass production feasible, it is therefore essential to gain a deeper understanding of the physicochemical behavior of antimony in glass, and more generally,
In solar glass specifically, small amounts of antimony oxide help stabilize optical properties under years of UV exposure, reducing “solarization” (the tendency of glass to brown or
The solar glass sector is ready to take back the European manufactured high-quality cullet at the end-of-life stage of PV panels and use it to produce new solar glass for the European solar PV industry.
This article explores a new process for extracting valuable antimony from the glass of solar panels, aimed at solving disposal challenges in the 2030s.
