New Material Can Absorb Infrared, Increase Solar Efficiency

ecogeek.org — Semiconductor solar cells absorb sunlight from the visible spectrum, ignoring ultraviolet and infrared rays, which limits how much energy a solar cell can create from sunlight. But a new material made by researchers in Spain throws titanium and vanadium into the mix so it can utilize infrared and potentially boost efficiency of solar cells. Aug 5, 2008 View in Crawl 4
