China’s largest solar company has started producing solar cells that use copper instead of silver, according to multiple reports. The change is driven by sharply rising silver prices, which have pressured costs across the solar industry since last year. By replacing silver with copper in cell components, the manufacturer aims to reduce exposure to volatility in the precious-metal market and contain production expenses. The reports describe the switch as an operational adjustment in the firm’s manufacturing process, rather than a one-off supply change. While the silver-to-copper transition is intended to address the economic impact of metal price swings, the articles do not provide detailed timelines for the scale of adoption, performance comparisons between the two materials, or specific financial impacts. Overall, the coverage indicates that the industry’s cost pressures from silver have prompted at least China’s top solar producer to alter its material sourcing and production approach to support continued manufacturing under higher input costs.
