Scientists at the Fraunhofer Institute for Solar Energy Systems ISE claim to have reduced the silver content of TOPCon solar cells tenfold.

Current solar PV module price increases are largely dictated by five major components, according to data from Intertek CEA

The cost of Chinese solar module manufacturing will rise in the first half of 2026, though prices may fall again before the end of the year.

As the year comes to an end, we bring you a recap of the most-read Premium stories that have been published throughout 2025.

Chinese researchers have developed a process to boost the efficiency and bifacial performance of TOPCon solar cells while reducing silver consumption.

Wood Mackenzie has warned of a supply bottleneck as the renewable energy shift drives a spike in global copper demand over the next decade.

PV Talk: AIKO's chief scientist, Yongqian Wang, tells PV Tech Premium that copper is now a “highly suitable” alternative to silver.

Researchers from the University of New South Wales (UNSW) and the University of Newcastle have found that “hidden contaminants” in TOPCon and HJT modules can lead to a power loss of up to 16%.

Fraunhofer ISE has developed a solar cell which uses “one-tenth” of the amount of silver as a standard cell.

Reducing silver consumption remains one of the key trends in the solar industry, such as going busbar-less, highlights the ITRPV.
