Fraunhofer ISE Research Cuts Silver Use In Solar Cells by 90% Updated On Tue, Apr 29th, 2025 by Saurenergy Scientists at Germany’s Fraunhofer Institute for Solar Energy Systems (ISE) have developed silicon heterojunction (SHJ) solar cells with silver consumption of just 1.4 milligrams per watt peak — about one-tenth (which is 90%) of the current industrial standard. The breakthrough comes as global demand for photovoltaics rises, with a shift to a climate-neutral energy system […] Read more
