Silver prices surge, yet 'thrifting' poses little threat to solar cell, module quality

With silver prices nearing $50 per ounce, researchers from the University of New South Wales (UNSW) and the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) tell pv magazine that efforts to reduce silver use in solar cells will not compromise module quality if properly engineered.Silver traded around $49 per ounce on Thursday, up from about $44 in the last week of September. The price increase and the possible crossing of the $50 threshold in the coming weeks or months are prompting the PV industry to intensify efforts to implement "thrifting," or reducing silver content in cells ...
