To my way of thinking, the important parameter is not output power versus input power but output power per dollar cost. The size of the arrays is generally not the deciding item. If their efficiency were only 10 percent, but they cost 10 […]

Photon Double Whammy: Careening electrons may rev up solar cells
A newfound cue ball effect in nanometer-scale crystals of a semiconductor compound may lead to highly efficient solar cells made from such nanocrystals.
