‘Fool’s gold’ aids discovery of new options for cheap, benign solar energy(PhysOrg.com) – Pyrite, better known as “fool’s gold,” was familiar to the ancient Romans and has fooled prospectors for centuries – but has now helped researchers at Oregon State University discover related compounds that offer new, cheap and promising options for solar energy.“These new compounds, unlike some solar cell materials made from rare, expensive or toxic elements, would be benign and could be processed from some of the most abundant elements on Earth. Findings on them have been published in Advanced Energy Materials, a professional journal.Iron pyrite itself has little value as a future solar energy compound, the scientists say, just as the brassy, yellow-toned mineral holds no value compared to the precious metal it resembles. But for more than 25 years it was known to have some desirable qualities that made it of interest for solar energy, and that spurred the recent research.The results have been anything but foolish…” -- source link
