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.

Is antimony selenosulfide a good solar cell material?

Antimony selenosulfide, Sb2 (S,Se)3, is a promising next-generation solar cell material with superior photovoltaic properties and high stability. However, the efficiency of Sb2 (S,Se)3 solar cells lags far behind its theoretical value and other well-established thin-film solar cells. Herein, we report a one-st

What is antimony used for?

The EIA projects solar capacity to reach over 300 GW by 2030 and around 700 GW by 2050. Beyond renewable energy, antimony is indispensable to national security. The Department of Defense (DoD) uses this critical mineral in 200+ types of munitions, including percussion primers, stab detonators, and armor-piercing rounds.

Why is antimony important in defense?

Antimony’s role in flame retardants further underscores its importance in defense. Military uniforms, equipment, and vehicles rely on antimony-based compounds for fire resistance, ensuring the safety of personnel in combat scenarios.

How can we meet antimony's growing demand?

To meet antimony’s growing demand, a multi-faceted approach is essential: Investment in Domestic Mining: Expanding mining operations in countries like the U.S. and Canada can reduce reliance on imports and strengthen supply chain resilience.

Why is antimony a bottleneck in the supply chain?

China controls nearly 50% of global antimony mining and 80% of processing, creating a bottleneck in the supply chain. Recent export restrictions by China, citing dual-use applications of the mineral for both civilian and military purposes, have exacerbated this dependence.
