Silver: the highest-conductivity metal behind solar and AI infrastructure
Key insights from this briefing
Why does the solar industry remain a major consumer of silver?
Silver has the highest electrical conductivity of any metal and is used in photovoltaic contacts to move current efficiently. Manufacturers continue to reduce silver intensity per watt, but the scale of global solar deployment means total industrial consumption can remain very large.
Why is silver important to AI data centres?
High-density computing requires efficient and reliable power delivery. Silver is used in switchgear, high-voltage circuit breakers and silver-plated copper connectors to minimise electrical resistance and manage heat in high-performance server infrastructure.
Excerpt from this briefing's Industry Insight
Silver remains the benchmark electrical conductor and is increasingly pulled between its monetary role and industrial demand. Solar manufacturing consumes large volumes even as producers reduce silver intensity per watt, while AI data centres rely on silver in switchgear, connectors and high-current power systems. Its antimicrobial properties also support medical uses in wound care and implants. The result is a metal whose industrial applications are becoming more strategically important at the same time as physical supply and investment demand influence price formation.
