Does solar glass contain antimony?

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 patterned solar glass but introduces environmental and health concerns, complicating recycling efforts.

Is antimony used in Photovoltaic Glass?

The flame-retardant sector currently accounts for around half of end use of antimony.“The use of antimony trioxide as a clarifying agent in photovoltaic glass is a developing trend, and it is expected to maintain rapid growth in the coming years,” Kang said.

Should antimony-free glass be used in New solar panels?

“ROSI advocates for antimony-free glass in new solar panels installed in Europe, notably through the Ecolabel directive, as it opens more doors for recycling,” he explained.

How can the US reduce antimony levels in solar glass?

The U.S. could also implement a threshold for antimony levels in solar glass, gradually reducing the allowable amount over time. This would encourage manufacturers to phase out the use of antimony in their production processes and facilitate more straightforward recycling in U.S. facilities.

Can you recycle solar glass with antimony?

This makes recycling solar glass with antimony both costly and technically challenging. Transporting glass cullets (crushed glass ready for recycling) also presents a logistical challenge, as their low density makes transport costly and inefficient. What is the regulatory support for solar glass recycling?

Can Borosil remove antimony from solar glass?

Borosil has been able to successfully remove the Antimony from Solar glass. Institut fur Solartechnik SPF, SWITZERLAND, widely considered a GOLD STANDARD for testing and certification of solar glass publishes on its website, test results of solar glass from some of the top solar glass manufacturers in the world.
