Particles allow cells to absorb more light, researchers say
(NEWSER) - Scientists believe they’ve found a way to make less expensive, more efficient solar cells: Just add silver, the Economist reports. Standard cells, which rely on a thick layer of pricey silicon, are costly. Problem is, thinner cells absorb less red light, reducing electricity output by 20%. Sprinkling a few cents’ worth of silver on the surface could solve this. More»
