According to Solar Power World, a key component of solar panels, silver, has seen a significant increase in price, influencing manufacturing approaches. This metal constitutes a notable portion of the manufacturing cost for silicon solar panels, with an even higher share for advanced n-type designs now prevalent in the market.
Silver prices, which remained below a certain threshold for over a decade, reached a peak in late January 2026 and have maintained elevated levels into March. Each silicon solar panel requires a specific quantity of silver, making the cost impact substantial for manufacturers.
In response, major solar brands are exploring methods to reduce silver content, often by increasing the proportion of copper. While copper is a conductive and less expensive alternative, researchers indicate the substitution may introduce unknown long-term durability concerns.
The integration of silver occurs during solar cell production, where it is used to form conductive grid patterns. The industry’s adoption of n-type technologies, such as TOPCon and HJT cells, has actually increased silver usage per watt compared to older PERC cell designs.
Industry estimates indicate that the volume of modules shipped in 2024 contained cells that consumed a significant tonnage of silver, representing over a quarter of the global supply that year. Global demand for silver has exceeded supply annually for several years, tightening the market.
The majority of silver production is a byproduct of mining other metals, complicating rapid output expansion. With limited ability to increase market supply, manufacturers are compelled to reduce usage.
Copper, however, presents technical challenges including a tendency to oxidize and risks of corrosion and diffusion into silicon, particularly at high processing temperatures used for some cell types. These issues are especially acute for TOPCon technology, which holds a dominant share of manufacturing capacity in a key producing nation.
Alternative cell designs like back-contact and HJT may offer more straightforward paths to reducing silver reliance. The transition pace is expected to vary by cell type, potentially shifting market shares in the coming years.
At least one major manufacturer has announced plans to begin substituting base metals for silver in its solar cells in the second quarter of 2026. Other leading companies are reportedly already using silver-coated copper pastes for some contacts and testing further applications.
These efforts have so far aimed to remain compatible with existing manufacturing lines to control capital costs. A shift to copper electroplating, more common in HJT production, would require new equipment.
Testing organizations are preparing to evaluate new failure modes associated with copper, such as oxidation and corrosion under thermal cycling and damp heat conditions. Experts note that industry experience with copper paste is limited and new failure types may emerge as solutions are deployed commercially.
Small defects in module packaging that are inconsequential for silver-based modules could become significant problems when copper is present underneath. Historical data from a now-acquired HJT manufacturer that used copper electroplating provides some evidence that copper can function in a solar cell, with modules from that venture reportedly passing extended reliability tests.
At least one Chinese manufacturer has already introduced a silver-free, all-back-contact module to several international markets, using a proprietary copper electroplated interconnection. The long-term performance of such designs moving away from silver will require extended testing to validate, as current mass-production experience spans only a few years, a short timeframe compared to typical product warranty periods.
