Microwave Oven Cooks Up Solar Cell Material
May 6, 2013 — University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity.
Using microwaves "is a fast way to make these particles that have a broad range of applications," says Michael Free, a professor of metallurgical engineering. "We hope in the next five years there will be some commercial products from this, and we are continuing to pursue applications and improvements. It's a good market, but we don't know exactly where the market will go." read more>>>
