Why do solar panels use antimony?

This results in higher energy conversion rates, making solar panels more effective at capturing sunlight. Additionally, antimony compounds increase thermal stability, allowing panels to endure extreme conditions without frequent replacements. Energy storage is another area where antimony shines.

Will antimony be used in photovoltaics?

The use of antimony in photovoltaics is expected to surpass its flame-retardant usage to become the major downstream use for the metal and will change the supply-demand balance in the antimony industry, a senior industry executive told Fastmarkets

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.

Should PV module manufacturers be required to disclose antimony compounds?

To address these challenges, the ESIA Recommendation paper suggests that the European Union should consider mandating PV module manufacturers under the upcoming Ecodesign regulations to disclose the composition and manufacturing process of solar glass, including additives like antimony compounds.

How will global demand for antimony grow in the future?

Global demand for antimony is expected to rise sharply in the coming years, particularly as renewable energy and defense sectors expand. Analysts predict that its market value could grow significantly, driven by advancements in solar technology, energy storage, and defense applications.

Why are antimony prices so high in China?

“The photovoltaic industry is mainly concentrated in China, which leads to higher demand for antimony in the country. Consequently, prices are naturally higher in China,” Kang said. Kang estimated the global antimony consumption in 2023 would be roughly 160,000 tonnes, and Twinkling Star’s planned production volume for 2023 is 26,000 tonnes.
